From high-efficiency replacements to annual service on the boiler you already own, we handle every step with the steady care of a specialist who's been at it for 20+ years.
A boiler is the heart of a hydronic home, and the wrong install can cost you for years. We help you choose, size, and install the right unit for your home, then maintain it so it actually delivers what the manufacturer promises.
Boilers often give warning signs before they fail. These are the signs most frequently reported by homeowners in the Bay Area.
Older boilers run far less efficiently than modern condensing units, even when they're still working.
A steady rise in your gas bill, even with the same usage, often points to a boiler losing efficiency.
Some rooms warm up, others stay cold. Often a circulator, zone valve, or pressure issue at the boiler.
A specialized team that will take care of your home as if it were their own.
We evaluate your existing system, your home, and your goals before recommending anything.
You get options, trade-offs, and an honest cost. No upsells, no pressure.
Our specialist handle the work with precision and real care
You'll know how to run your new system, and we check back to confirm everything is dialed in.
A boiler installed by a generalist can underperform for its entire 15-20 year life. We bring 20+ years of focused hydronic experience and high-efficiency expertise to every job.
After hearing an increasingly loud hissing sound in my kitchen wall, I gave Afterglow a call, worried it was a gas leak. Mniska was prompt, professional and focused. He also took time to explain what steps he was taking to hone in on the problem. He was able to fix the leaky hot water pipe in my wall skillfully and smoothly.
All plumbing experiences should be this pleasant and easy. Mniska gave me a clear, accurate estimate for all work, including the installation of an automatic gas shut-off valve on my house gas line, which shuts off in case of earthquake, along with a tutorial on how to use and/or reset it. He also performed a major seasonal flush of my on-demand water heater, as well as several minor deferred maintenance faucet-related fixes. Thanks!
Great experience with Afterglow: Mniska is very knowledgable, describe the work order in detail and answer questions.
Afterglow heating provided us with thoughtful advice regarding our plans for radiant floor heat that saved us a ton of headache. They provide exceptional service with impeccable attention to detail. Highly recommended!
Mniska taught us about our system, reviewed all of our options, and helped us decide how to proceed. His work was excellent. We are warm in our apartment for the first time in 9 years.
Highly recommend Afterglow Radiant Heating! Mniska Lamb, the owner, quickly diagnosed and fixed our intermittent hot water issue with our tankless system. He completed important maintenance, suggested valuable upgrades, and communicated clearly throughout the process. He worked efficiently, was respectful of our home (and our two cats!), and I trust him completely. He's now on my schedule for annual maintenance and ongoing service.
For most Bay Area homes with hydronic heating, yes. Modern condensing boilers run at 90-95% efficiency compared to 70-80% on older units, and many installs qualify for utility rebates. Over a 15-year lifespan the savings usually outweigh the upgrade cost.
Costs depend on the size of your home, the model, venting requirements, and the condition of the existing piping. A straightforward replacement can range from several thousand dollars upward. Call us for an estimate.
Once a year, ideally before the heating season. Annual service includes pressure checks, safety control tests, expansion tank inspection, and a flush if needed. It's the single best way to extend the life of the unit.
It comes down to how much of the fuel a boiler turns into usable heat, measured by its AFUE rating. A condensing boiler pulls extra heat out of the exhaust gases that older, non-condensing units sent straight up the flue. The result is more warmth from the same fuel and a lower gas bill.
Often, yes. We diagnose the actual cause before recommending replacement, and we'll be honest about whether a repair is the right call or whether a replacement will save you money over time.
