I have used Anderson for more than a decade for my Eichler. They serviced the original boiler installed in 1960 and kept it and the grid repaired and working efficiently until last year when we did some remodeling and decided to upgrade to a contenporary high-efficieny unit. The installation was absolutely great, the pricing was competitive, and Glen followed up with us often afterwards to make sure we were happy and that we knew how to adjust it properly. We had the System with seperate stainless steel hot water tank. Always plenty of hot water and the flooring is cozy and warm. Additionally I have had occassion to refer Anderson about a dozen times to other Eichler owners all of whom have been delighted with the work. Fast, efficient and their work is beuatiful and shows the pride they take in it. I work with a lot of trades people and a lot of really good ones. Glen exemplifies everything you want in a contractor. Explains everything carefully, offers options for solution, competitive pricing, on-time and on-budget and always there afterwards to support. Thank you Anderson Radiant!! read more

Glenn has a skilled in depth understanding of radiant heating systems and related problem solving. Our system is 18 years old and was not heating the house adequately. It was also making worrisome pipe banging noises. Glenn squeezed us in at the end of a busy day due to our worries of system damage. Within minutes of his arrival he had identified that we had a low pressure problem in the heating loops that circulate hot water through our floors. He quickly repressurized the system and the pipe banging went away. Then he thoroughly checked out the rest of our system and identified that we had a number of sticking valves that controlled different heating areas in the house. He made a second trip and replaced all the valves with new ones. After he was done the system was operating like new. His prices were reasonable and worth every penny to get our system working like new again. Next time there will be no doubt as to who to call. read more

after having one wet area manifest in our eichler concrete slab, we scheduled anderson radiant heating to come out for a round of leak detection. after a challenging day with our atypical 1950s-era townhome hydronic system, glen and his crew found/repaired a total of 3 leaks in our slab. subsequently our neighbors have also used them as well to great effect (including finding/repairing a leak in the slab that previously went undetected by another contractor also trying to use an inert gas detection method.) put simply, these guys are the best. it might take a while to get through to them on the phone (keep trying!) but if you are looking for topnotch (helium+spectrometer) leak detection along with expert repair/maintenance/install of hydronic heating systems then they are literally the best out there. also extremely knowledgeable specifically about eichler hydronic systems. we looked high and low and are convinced there is no better vendor for leak detection/repair and hydronic service for our eichler. [pro tip: ask larry about for the story of how he initially discovered the helium+spectroscopy leak detection method] read more

Last month we bought a 1962 Eichler home in Marin from the original owners that we are currently updating. Before buying, we had a hydronic heating system inspection from a contractor that stated we had no leaks in our system. The same contractor said we had a leak at our boiler on the flange with supposedly no problem with the pump. Lo and behold, only one week later we see water coming up through cracks in the floor. Luckily, we had torn out the layers of old flooring so we were able to easily see the water. I asked neighbors for referrals and researched for a specialist that could help us. Anderson Radiant Heating was suggested and after looking at their excellent, extensive, and very educational website I realized how the original inspection was in no way adequate to determine whether there were any leaks or not. Apparently this happens all the time to prospective owners, like us, who have no experience with a hydronic system and who have no way of knowing if we are being ripped off. The good news is that Glen fixed the leaks that I was able to see, one I was able to hear and 6 more that were small but detectable with the specialized equipment that they use. It was a fascinating process. I was blown away by how detailed a job Glen performed. I was scared about having to break into the slab that also contains our plumbing and electrical but Glen did it so carefully and with great skill that I quit worrying after the first repair was made. And that boiler pump that we were told was ok? Not so. It was visibly cracked. I don't know how it even functioned. Glen replaced that and also made fixes to the boiler installation that were done improperly. I am much relieved to know that my system is leak free before having 2000+ sq ft of tile installed. Other positives: Glen explained everything. The price was reasonable given the work required. And, they even came up from Campbell! read more

We live in an Eichler-built home and have undergone several rennovation projects since moving in. We still had the original boiler (1960) and that thing was as inefficient as all get-out. For obvious reasons, we needed to get a new one. I contacted Anderson and one other outfit to provide a quote. Both companies were recommended by neighbors who have had similar work done, but the more glowing recommendation was for Anderson. I specifically wanted to use a company that is experienced in Eichler homes even though I know that would cost extra since this is the type of thing you shouldn't cheap out on. Glen's quote was very reasonable relative to the unit and work required, and he was able to answer all my questions. The other company quoted much higher and was unable to articulate why their apples to apples quote came out for much more. All he could tell me was "We do it better." When I asked what exactly they do so much better to justify such a higher quote, all he could reply was, "We just do everything better." Ummm, no thank you, Mr. Confidence; if you can't provide specifics, I can't provide you my money. Glen just installed the unit last week, and I learned that he was very familiar with our home from the past few owners and was able to give us some information on the history of the home beyond the last owners, which was very helpful. He and his assistant did a very clean job, and Glen provided a thorough orientation of the unit and thermostat. He also offered up some recommendations So far, the unit is running beautifully and our floors are so nice and toasty! I know the manufacturer of the boiler also offers an indirect fire water heater that can be paired with the boiler. Since we are in the market for a new water heater, I asked Glen if he could install one of these and what the damage would be. Rather than trying to get a sale, he was very candid in informing me that he unit would be too much for our needs and that we wouldn't see any form of savings for a very long time. He recommended we consider other options that would perform well, and also hit our pocketbook more lightly. I appreciate a straight-shooter like that! read more

Efficient, effective, excellent service is how to best describe my experience with Anderson Radiant Heating. Finding and fixing a radiant heating leak in a concrete slab is a two-step process, but they can do it all in one visit as opposed to the prolonged and costly cycle of repeatedly contacting a leak detection company, then contacting someone else to fix the leak. They seemed both conscientious and thorough - determined to complete the job in a timely manner. Additionally, they kept us in the loop -- suggesting the least intrusive approach and helping clear the areas that needed work. read more

We recently had a water leak problem in the powder room under the sink area. The first 2 plumbing crew dispatched by the insurance company were hopeless, and we finally had to find our own plumber. Not knowing who to call, especially for an Eichler house, we looked up Yelp and decided on Anderson Radiant Heating company based on all the positive reviews. We are not disappointed at all! From the initial phone call to schedule an appointment, to debug the source of the leak, and to perform the repair, Glen and his dad are top notch in their trade. The repair time was just as quoted, even with the source of the leak being deeper under the cement slab than first thought . Being an expert in radiant heating system really made a difference here, as the digging part of the job was very localized. Overall, we are very happy with Anderson Radiant Heating, and would recommend to anyone who needs quality work. Way to go, Glen! read more

Last night water started to pour out of our water heater storage tank, through the pressure release valve and attached copper pipe, and into a poorly installed drain system. The drain set up did not work properly and so water leaked into many rooms. We called Glen and he showed up last night. He spent time diagnosing the system and found the pressure release valve had gone bad. Instead of leaving me without hot water, he ran out to the hardware store, bought a new valve and installed it, and tested the system to make sure all was working properly. In addition, he went above and beyond that service by adding copper pipe and modifying the drain so that if if happened again the water would not leak into the other areas. Great job, amazing night time rescue service. THANKS! read more

We've been using Anderson for a long time to keep our old boiler running despite my best efforts to neglect it as much as possible. Recently we had Anderson over to perform a long over due preventive maintenance. Glen informed us the boiler was on its last legs and was emitting more than the recommended carbon monoxide. So, we decided to bite the bullet and get a new one. They came over today to install it. Arrived punctually, three people worked all day, and then proudly showed off their excellent work. As an example of their pride in workmanship, although not something we paid for, they rebuilt the boiler closet with beautiful wood siding to cover over the completely rotted out dry wall that was there before. Looking forward to seeing how the new boiler performs this winter. read more

Anderson Radiant Heating is the _best_ company out there for any of your heating needs. I have hired Glen consistently to maintain an old boiler and he is awesome. Very professional. On time. No BS with his rate. He explains everything that is wrong and he explains everything he is doing or about to do to fix the problem. He gives you heads up on potential problems and how to mitigate them. He doesn't waste time and slack as he is fixing the issues like others to so they can stretch they hours on site. He gives you a formal receipts with detailed explanation of everything he did and recommendations. You will be impressed by his knowledge and professionalism. read more

Excellent service, highly recommend. I recently moved into an Eichler home that had what seemed, the original radiant heating system and an old water boiler. One day a pipe started to leak and I contacted Anderson. Glen got the call and stopped by quickly assessing the situation and replacing the part. Without a sales pitch or any pressure he shared his knowledge of the system and the recommendation of what to get when I was ready to upgrade. Fast forward, after researching and reading multiple reviews, he and his team came out to install a new water heater and boiler. The price was on the higher end, however I believe I am getting what I'm paying for. While he was on site, he noticed a water leak unrelated to their work. Turns out my grey water valve had been turned resulting in large volumes of water lost. Thanks to Glen who went beyond what he was there for, we could isolate the issue and stop the water loss. So in addition to getting a system that is beautifully done (labelled, clean installation, easy to read/decipher any issues, painted to match the house, etc.), Glen saved the day wrt the water leak- again! He is very knowledgeable and follows through 100% to ensure your satisfaction. read more

It can be challenging to have a rental property in the Bay Area and live in Southern California. Luckily I have the best renters, and lucky for us all, Anderson Radiant Heating is super responsive and experienced! When the water pump on the heating system leaked majorly, the carpet was completely soaked and no heat in the house, my immediate thought was another company that had come out in the past. Turns out they couldn't get by to even take a look until a week later. A week with no heat....in December? After looking on Yelp and seeing very good reviews for Anderson which is also close by, and leaving a voice message, they were able to come by in the evening the very next day to make sure there was heat in the house. Swapped out the pump with no problem. Clearly very caring, competent and lots of knowledge and expertise with radiant heat. I definitely recommend them and they will be our "go to" for any needs down the road. Thank you Anderson Radiant Heat! read more

The guys at Anderson Radiant Heating really knows their stuff. We are moving to an Eichler that has radiant heating, but it has not been turned on for 30 years. Glen checked for leaks and explained our options. They were professional and knowledgable. They saved us from putting a brand new system which would have costed a pretty penny. I would highly recommend Anderson Radian Heating. read more

I'm not sure if the previous reviews are about the same company... Glen is a fantastic guy and I have yet to see any contractor as professional, on-time and competent as him. They really understand radiant heating and do a fantastic job. I just replaced our radiant boiler and water heater with him and cannot be more pleased - they were the best and the cheapest out there. He was only bothered about doing a fantastic job and doing it efficiently. He and his helper took 6 hrs to do what most others would take 2 days. We have also used their service in the past for fixing leaks and pressure testing our radiant system and have always been pleased. I would trust these guys with a blank check. PS: I'm not a regular when it comes to writing reviews, but when I saw these poor reviews I was surprised and wanted to share my story. Update 7/5: I did steal that quote from Hunter about the "blank check" - sorry Hunter, should have given you the credit. Also, unfortunately the Rheem water heater turned out to be a lemon. Glen is trying to get it sorted out... it's starting to get a little frustrating. read more

Anderson Radiant Heating (Glen) is the best! They are experts! Glen fixed our leaky pipe issue on short notice in our Eichler. He saved us from a huge disaster and I know if anyone else stepped foot in our house, we would of had a demolished bathroom, without a doubt! Glen's knowledge and expertise of Eichlers and his thinking outside the box saved us. Glen is thorough, accurate and knows his stuff (I could go on and on). I would recommend Anderson Radiant Heating. read more

Our first experience with Anderson was a very impressive one. They performed an inspection of our radiant heating system, cleaned up the boiler, and determined that there was leakage in the copper piping in the concrete slab. A team of three returned and in one day detected and repaired eight individual leaks with very little impact on us. The job was made more difficult by the unusually thick concrete slab. The work was done efficiently and professionally with a cleanup that left no evidence of any repair work having been done. Many thanks to Anderson, a family-run company. read more

Anderson Radiant Heating deserves 25 stars! I've lived in my Eichler for 46 years. Over time, I've had to replace and to repair the boiler as well as to fix a leak. I thought the previous radiant heat companies were good, but Glen and his crew were fantastic. Initially, Glen fixed the boiler after I heard very loud noises after turning it on for the winter. Glen said the pressure gauge showed that I had a leak somewhere. When he came to fix it, Glen explained everything very clearly. Using his "sniffing machine," he found and fixed the leak. He told me that he had to wait a while until the pressure built up again to check for additional leaks, and repeating the process, he found two more. Before he left, he did several final checks. I told a friend of mine who had a radiant heat leak repaired several years ago (but not by Glen). The repairman left immediately after fixing the leak, then within weeks, she had another one. Meanwhile, she had replaced the flooring and had the furniture moved back, just to have to do both all over again. Glen's thoroughness and expertise prevented that problem for me--twice! Besides being so knowledgeable, thorough, and exceptionally neat, Glen and his crew were very careful moving a large antique piece and a heavy desk. I can't imagine a more professional, effective, expert radiant heat service--and they were exceptionally nice people as well. read more

Glen is the most knowledgeable radiant heating technician that I have met. His expertise in plumbing, electrical, and heating was clear as he troubleshot the issues with our heating system, creating a plan, and executed on it. His efficiency of working with his partner was the best I have experienced of any tradesman with whom I have worked (and we have had a lot through the years). And efficiency makes you feel that you are getting value for the money you spend. Five stars does not say enough! If you have issues, call them and get on their calendar. read more

Eager to come and repair and even more eager to collect...despite having sent in my check, two people showed up at my door to get another check. Left unrepaired holes in the foundation which allowed ants to invade our house and never returned phone calls for them to come back and fix the problem. I would suggest you check around at others before using them as they seem more eager to collect your money than make sure everything is ok. read more

My boiler was not working and after a quick call with Glen, he talked me through troubleshooting it. Any other company might (and could) have easily taken my money from a visit. He seemed incredibly knowledgable on the phone -- calling out locations, colors and of switches just from memory. When I do need boiler service again, I'll happily call Anderson. read more

Anderson fixed my boiler and did a great job. Having problems again, does anyone have his cell phone number since the business phone does not pick up. Boiler or thermostat shut down last night and I need immediate help. DOES ANYONE HAVE GLEN'S CELL PHONE NUMBER????????????? read more

I contacted Glen at Anderson because of a review I read about them on the Eichler Network. I just moved to the Bay Area and was in the process of purchasing an Eichler that had not been very well maintained. I was told by the sellers agent that the radiant heating was in working condition, but I was dubious. Glen came out and did a test of the system and as I expected, there was considerable leakage. I hired him to fix the system, and I'm so glad I did. He was able to pinpoint the problem areas and uncovered some pretty scary fixes that the previous owners used to remedy leaks in the system. Apparently, they used irrigation hose with hose clamps to bridge between the copper radiant tubing. Thankfully, Glen fixed the problem areas correctly in a matter of hours, and the system is back to truly working condition. They are definitely masters of their trade, and offer a lot of great free advice for how to maintain the system. I also really appreciated that they asked me before doing extra work outside of the contract instead of just going ahead and then presenting me with additional fees after the fact. There are only a handful of companies that specialize in radiant systems in the Bay Area, and while they may not be the cheapest option, I personally wouldn't trust anyone else with my system. read more

We needed our boiler replaced. The boiler was located in the basement of our home built in 1907. We had a series of contractors bid the porject, although each of these contractors engaged in some level of double talk about what they might experience during the course of the project. Glen of Anderson Radiant Heating showed up. He gave us a precise bid and start date. More importantly, it was clear he had extensive knowledge of all aspects of radiant heat systems. His bid was slightly higher than the other contractors, but worth every nickel. He (Glen himself) started the job on the day promised, and finished the next afternoon. The system works perfect. Glen takes tremendous pride in his works. For obvious reasons, Glen is busy. We strongly recommend that anyone needing quality work, wait for Glen. He is worth it. read more

We suspected that we had a leak in our Eichker heating system, and based on the favorable reviews in Yelp, we called Anderson Radiant Heating. Glen and his team were punctual, professional and efficient. They detected two leaks (one under a built-in closet and one under wood flooring.) Within six hours, they had jack-hammered the concrete floor, replaced the damaged copper tubing, filled the holes with new cement and restored the closet and flooring to their original condition. In addition, they replaced some of the old valves and cleaned the boiler. At all times, Glen kept us informed of what they had discovered and gave suggestions on the best (and least expensive) options for fixes. We're extremely pleased with the work that they did, and can recommend them highly for radiant heat repairs. read more

Glen from Anderson recently installed a new boiler at our home. The job turned out to be more complicated than we thought when he bid. He honored his quote and did a FABULOUS job......awesome workmanship. read more

I inherited a hydronic heating in my house, and when the boiler stopped working I had a lot of trouble finding anyone who understood it well enough to fix it. Even over the phone I could tell that Glen knew my system very well. He managed to troubleshoot the boiler and also fixed a few other issues which had been bothering me and got me back up and running quickly. Thanks! read more

I was able to witness firsthand as to why all my neighbors swear by Anderson's services. Top notch service. Our faulty pipe was jack hammered and removed surgically and quickly. And much to my surprise, Anderson was able to perform their services cheaper than their original estimate and cheaper than the other two estimates I received. read more

I was in an unfortunate position of needing a company to finish the partially completed radiant heating for my new home. I was referred to Anderson and Glen by another vendor. It turned out to be a great call. Glen is extremely knowledgable and professional. He is very busy (because he is that good) and it took a few calls to reach him but Anderson is worth the wait and I was very pleased with the expertise and the quality of work. read more

Managed to squeeze me in during a busy time for them, fixed my boiler, and did so for less than I thought it would be. What's better than that? read more

I had Glen Wagner of Anderson Radiant Heating (www.radiantheat.net) up to fix my A. O. Smith boiler system (hydronics) which had a new under the floor leak (the system was losing pressure) and bad thermostat and intermittent error in the ignition system. He did a great job. I bought the house (in Concord) five years ago and it lacked 20 years of maintenance. The pump had been replaced as part of a VA purchase but the ignition system and thermostat weren't working properly. Also, the burner hadn't been adjusted for efficiency. I had the firm that replaced the pump back within months of buying the house but they left me with an inoperative system. I had to turn the system on and off daily to heat the house during the winter and it was never warm. I lived with it but it was troublesome. Anyway, Glen found the leak using a helium leak detection technique (As a physics major I was impressed). He removed the concrete and replaced the defective section of pipe and repiped around a construction defect (from 1965!) . He replaced the pressure safety valve, it was old and grotty. He replaced the thermostat, it was the wrong type. And he replaced the defective components in the ignition system that were causing the intermittent start and stop failures for the system. He also replaced the expansion tank (rusty and not working well) and added a couple of valves needed for testing and repairwork. He adjusted the burner to burn clean. And checked and cleaned the heat exchanger. He even improved on the chimney structure. Also he checked the rest of the house for leaks using the helium detection method. He and his helper worked straight through. They had all the parts that were needed with them. (As an ex-AF jet mech I was impressed :-D) The house is warm and comfortable, quite a relief, and I wish I hadn't waited so long (until the leak) to call for help. I strongly recommend him. read more

Quality, integrity, responsible, responsive and cost effective ! Strong recommendation for ANDERSON RADIANT HEATING. Live in a Mountain View Eichler. Sharply increasing gas and water bills investigated to find that there is a hot water system leak, 1 gal/min (1500 gal/day); under the building slab. Initially had two leak detection specialists investigate that resulted in three different leak sites. One under the sliding glass door from kitchen to atrium, one about a foot inside the house by same sliding glass door and the third in a bathroom on the opposite side of the house. Concerned about digging unnecessary holes in the slab, we called Anderson for a third opinion. Glen and Larry came and used a helium leak detection unit to locate the leak (other two leak detection specialists used a "stethoscopic" location method). They we not rushed and careful; finally concluding the leak was about one foot on the atrium side of the sliding glass door. This is fortunate since there is no radiant heating pipes under the atrium and hence no need to go through the radiant heating system with potential damage, to reach the hot water pipe below the concrete slab. They were able to locate the leak (about a 5/64" hole, pitted from the outside) after jack hammering a little less than a one square foot hole. Continuous vacuuming during the excavation to minimize dust. About a one foot section of pipe with the leak was cut out and a clean new pipe section silver soldered in via couplings at each end; very clean brazed joints. Anderson was careful to pressurize the system then and make sure there were no other leaks. Jack hammer rubble was used to fill the hole and then a quick concrete patch applied. Glen was meticulous in leveling, drying and texturing the patch. Excellent job of clean up. NET: Total job completed in less than 4 hours including patch and cleanup. Avoided the possibility of three holes in my slab, through a radiant heating system, and no leak found. Helium leak detect the way to go to minimize cutting through the concrete slab. read more

This is the company to call if you own an Eichler. We had Glen Wagner(owner) come out to do an inspection on our radiant heating system. He really knows his work. He is honest, reliable, prompt and professional. He's the guy to get! read more

We had a 55 year old radiant heating system in a 6000 sq foot house that had numerous problems. In addition to several leaks in the system that Glen was able to locate quickly, we had the original furnace. That furnace weighed 750 lbs, was dirty, and inefficient. Glen replaced it and put in new pumps. His work is impeccable and his skill set impressive. You don't want anyone else messing with your radiant heating system! read more

Glen and the team were excellent to work with: prompt, courteous, thorough, and very helpful in explaining the work they were doing. Glen came to check our Eichler's radiant heat system before we installed a new floor. Our 58-year-old boiler (which had been installed by his grandfather) was in such poor shape Glen couldn't even test. He promptly installed a new boiler and his initial test indicated a leak. He returned to pinpoint the leak - and spent hours searching thoroughly but fruitlessly. Glen suspected the initial test might have been flawed, which he said is unusual but can happen. We gratefully accepted his offer to retest once the old floor was demo'd and the slab was exposed - and indeed, he found no leak. Glen didn't charge us for either of those testing visits, despite the considerable time he spent here and some inconvenient scheduling. We especially appreciated his patience and attention to detail, both in the work itself and in making sure we understood the new boiler and how to best care for our system. read more

We finally decided to address the radiant heating issue and found Glen through Yelp. We had a very old boiler for radiant heating sitting in a closet in our master bedroom which is a gas leak hazard. Furthermore, we were told by other contractor that there is a leak but no one can find where it is. We decided to let Glen fix all the problems at once. He completely gutted the old boiler and put the new energy efficient boiler in an outside boiler room, completely vacant the closet space. He cleaned out all the old Solar pipes on our roof in order to routing the hot water from the boiler to the ground pipes. Fixed two leaks underground. It was a fantastic job. The city inspector was very impressed with our Boiler room and all the neat placement of pipes and boiler there, he told me to recommend this contractor to my friends. Now I have finally got a walk in closet, a radiant heating system that works great that I can enjoy the winter in a warm home. The only regret that I have is that I should have called Glen 5 years ago... read more
