Engineering first, equipment second
A hydronic system is only as good as its design. Whether it's radiant floors, a boiler, snow melt, or all of them tied together, the difference between a system that quietly delivers comfort for decades and one that never quite works comes down to the engineering behind it. At Phillips Hydronics we design every system from the ground up — and because we install what we design, the plan on paper actually matches what gets built.
Custom hydronic design
Our design process starts with the numbers. We run a room-by-room heat-loss calculation for your specific home, then design the distribution — radiant loops, baseboard, panel radiators, or a combination — to deliver exactly the right amount of heat to each space. From there we size the boiler and heat source, lay out the near-boiler piping and zoning, select circulators and controls, and integrate any extras like snow melt, indirect domestic hot water, solar thermal, or geothermal. You get a system that's balanced, efficient, and built to work as one.
Heat-loss calculations
Every design is sized to your home's real load, room by room — never rules of thumb.
Whole-system integration
Radiant, boilers, snow melt, solar, and domestic hot water designed to work together.
Smart zoning & controls
Independent control of each area for comfort where you want it and savings everywhere else.
Contractor-ready plans
Clear designs builders and GCs can build to, with one specialist owning the hydronic scope.
Ongoing maintenance & service plans
Hydronic systems are durable, but they aren't maintenance-free. An annual service keeps efficiency high, extends equipment life, and — most importantly — catches small issues in the fall before they become no-heat emergencies in January. Our maintenance visits typically include checking and adjusting system pressure and the expansion tank, inspecting and purging air from the loops, testing controls and safeties, checking the circulators, servicing the boiler and its combustion, verifying glycol/antifreeze levels in snow-melt and exposed systems, and balancing zones that have drifted.
Service for systems we didn't install
You don't have to be an existing customer. We service and troubleshoot hydronic systems throughout Utah no matter who installed them — including older or poorly designed systems that need to be diagnosed, corrected, or modernized. If a previous installer left you with a system that never worked right, we can often re-engineer the problem areas rather than starting over.
Protect your investment
A hydronic system is a significant investment in your home's comfort and value. Regular maintenance protects that investment, keeps manufacturer warranties valid, and keeps your energy bills where they should be. Ask us about a recurring service plan so you never have to remember to schedule it.
Frequently asked questions
How often should a hydronic system be serviced?
Once a year, ideally in late summer or early fall before the heating season. Annual service keeps efficiency up, protects your warranty, and catches small issues before they become winter emergencies. Snow-melt and glycol systems benefit from a check on antifreeze levels too.
Why does system design matter so much?
Because comfort and efficiency are designed in, not added later. A correctly sized boiler, properly zoned loops, and balanced distribution mean even heat and low bills. An undersized, oversized, or poorly zoned system never quite works no matter how good the equipment is.
Will you service a system another company installed?
Yes. We service, troubleshoot, and re-engineer hydronic systems across Utah regardless of who installed them, including older systems that need to be corrected or modernized.
What's included in a maintenance visit?
Typically: checking system pressure and the expansion tank, purging air from loops, testing controls and safeties, inspecting circulators, servicing the boiler and combustion, checking glycol levels where applicable, and re-balancing zones. We tailor it to your specific system.
