20+ years of focused experience with radiant heating, also known as hydronic heating, brought to every radiant floor, baseboard loop, and boiler-fed radiator we touch.
Hydronic and radiant heating is at the core of what we do, not an add-on service. That means when you're deciding between a boiler repair and a full replacement, or figuring out whether an air-to-water heat pump fits your home, you're getting answers from a team that's done it hundreds of times.
Older Bay Area homes were built with radiant and hydronic systems that last decades, but valves corrode, boilers lose efficiency, and floors develop cold spots. Here's what we hear most.
Air pockets, failing manifolds, or zone valve issues can leave parts of your floor cold while others run hot.
Often a sign of trapped air, low system pressure, or worn check valves in the boiler loop.
An aging boiler losing efficiency is one of the most common culprits behind a steady creep in heating costs.
Our specialists handle your project from first call to final walkthrough. Steady, careful, and explained as we go.
We take the time to listen to your concerns and explain your system in easy to understand terms so you can make informed decisions for your homes needs

A walkthrough confirming everything runs the way it should, with notes for future maintenance.
20+ years on radiant heating systems means we've seen every brand, every era of installation, and every quirk older Berkeley and Oakland homes can throw at us. You get that depth from a specialist, start to finish.
Mniska was amazing, he helped set up our water filter and was great to work with. He was extra clean and tidy, was thoughtful and provided excellent ideas and information including a video to make sure I knew what to do in the future. He was quick to respond to my inquiries and did a quick job. I will be using him moving forward for all my plumbing needs. I highly recommend him.

When our tankless water heater broke, I called Mniska and he came the same day. He was very good and thorough. He patiently explained our options and answered all our questions. Definitely recommend!
Mniska approaches projects with care, intensive attention to detail, and a laser focus on his clients' wants and needs--he's the definition of a consummate pro. Highest recommendation.
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.
Mniska came to our rescue fast and did a thorough investigation of our failing boiler. He was able to fix all of the problems as well as a shower arm issue we were having. He was thoughtful, efficient, informative and very helpful. It was a long project that took most of the day but he stayed until it was finished and made sure the house was as clean as when he arrived. Thank you for helping us out!
Radiant heating, also called hydronic heating, circulates hot water through pipes to radiators, baseboards, or radiant floor tubing. Many older Berkeley and Oakland homes were built with these systems. The existing distribution can usually be preserved while upgrading to a high-efficiency boiler or air-to-water heat pump for better performance and lower energy costs.
Radiant heating uses water to distribute warmth, while forced air blows heated air through ducts. Water carries heat more effectively than air, so radiant (hydronic) systems deliver more even, consistent comfort without drafts, dust circulation, or blower noise.
We recommend annual maintenance on the boiler or heat source. That includes checking pressure, testing safety controls, inspecting the expansion tank, and flushing if needed. Radiant floor tubing can last 50+ years with minimal attention.
Yes. Air-to-water heat pumps are designed to integrate with existing hydronic distribution including radiant floors, baseboards, and radiators. The Bay Area's mild climate makes them particularly efficient, and many installations qualify for California rebates and federal tax credits.
Costs depend on scope, system type, and the condition of existing infrastructure. A boiler replacement can range from several thousand dollars depending on the unit and complexity. A full radiant floor installation is a larger investment but adds significant home value. Call us for an estimate.
