The heart of your hydronic system
The boiler is what makes radiant floors, baseboard, snow melt, and domestic hot water all possible — and it's the one piece of equipment where correct sizing and installation matter most. As a licensed Utah boiler and pipeline contractor, Phillips Hydronics installs, replaces, and repairs hydronic boilers for homes and commercial buildings throughout the state. Because hydronics is all we do, we approach a boiler not as a box to swap but as the core of a system that has to be engineered as a whole.
Boiler replacement done right
Most boiler calls we get are replacements — an old, oversized, or failing unit that's costing too much to run or no longer keeping up. The biggest mistake we see is simply matching the new boiler to the old one's size. We start with a proper heat-loss calculation so your new boiler is sized to your home's actual load, then we install a modern high-efficiency condensing unit that modulates its output to match demand. The payoff is lower gas bills, more even heat, quieter operation, and a system that isn't short-cycling itself to an early grave.
Correctly sized
Heat-loss calculation first — no guessing, no oversized equipment burning extra gas.
High-efficiency units
Modern condensing boilers that modulate output and reach efficiencies older units can't touch.
Clean, serviceable piping
Near-boiler piping done to spec so the system runs right and is easy to maintain for years.
Licensed & permitted
Work done by a licensed boiler contractor, permitted and inspected where required.
New boiler installation
For new construction and additions, we size and install the boiler as part of the larger hydronic design — coordinating it with the radiant zones, snow melt, indirect water heaters, and controls so everything works together from day one. We handle near-boiler piping, primary/secondary loops, expansion and air management, venting, and the controls that tie it all together.
Boiler repair & troubleshooting
When a boiler goes down in a Utah winter, it's not something that can wait. We diagnose and repair no-heat calls, leaks, pressure problems, ignition and short-cycling issues, circulator failures, and control faults. Because we understand the entire hydronic system — not just the boiler — we can find root causes that a general HVAC tech might miss. And if a unit is genuinely past its service life, we'll tell you honestly rather than selling you repair after repair.
Maintenance keeps it running
An annual boiler service keeps efficiency up, catches small problems before they become winter emergencies, and protects your warranty. We offer maintenance for the systems we install and for existing boilers across Utah — see our maintenance and design page for what's included.
Frequently asked questions
How long does a boiler last?
A quality hydronic boiler typically lasts 15–25 years with regular maintenance. Condensing boilers tend toward the lower end, cast-iron units the higher end. If yours is over 15 years old and needing repairs, it's worth pricing a replacement against the rising repair and fuel costs.
Should I repair or replace my boiler?
If the boiler is under ~10 years old and the repair is minor, repair usually makes sense. If it's older, inefficient, oversized, or facing a major repair, replacement with a correctly sized high-efficiency unit often pays for itself in lower bills. We'll give you an honest assessment either way.
What size boiler do I need?
It depends on your home's actual heat loss — not its square footage alone or the size of your old boiler. We run a heat-loss calculation that accounts for insulation, windows, climate zone, and the loads it serves so the boiler is sized correctly. Oversized boilers waste fuel and wear out faster.
Do you offer emergency boiler repair?
Yes. We're available for no-heat and boiler emergencies — call (385) 234-1916. A failed boiler in a Utah winter is urgent, and we prioritize getting heat restored.
