Heat that comes from the ground
A few feet below the surface, the earth stays a steady temperature year-round. Geothermal heating taps into that constant warmth with a ground-source heat pump and a buried loop field, then delivers it through your hydronic system. The result is one of the most efficient ways to heat a building that exists — and because it pairs so naturally with radiant floors, it's a perfect match for what Phillips Hydronics does.
Geothermal is a bigger upfront investment than a conventional boiler, but for the right home or commercial project in Utah it delivers the lowest long-term running costs and a clean, renewable heat source that doesn't burn fuel on site. We design and install complete geothermal-hydronic systems statewide.
Why geothermal pairs perfectly with hydronic radiant
Ground-source heat pumps are happiest delivering moderate water temperatures — and that's exactly what radiant floor heating wants. Radiant runs efficiently on lower water temperatures than baseboard or forced air, so a geothermal heat pump and a radiant floor are an ideal technical match. Together they produce deep, even, silent warmth at remarkably low operating cost. We engineer the whole system — loop field, heat pump, radiant distribution, controls, and backup — as one integrated design.
Exceptional efficiency
Moves heat instead of burning fuel, delivering several units of heat per unit of electricity.
Renewable & clean
No on-site combustion — steady, renewable heat drawn from the earth.
Heating and cooling
A geothermal heat pump can reverse in summer to provide efficient cooling too.
Long system life
The buried ground loop can last for decades, with the heat pump as the serviceable component.
Is geothermal right for your project?
Geothermal makes the most sense on new construction and major remodels where the ground loop can be installed during site work, and where the home or building will be lived in long enough to recoup the upfront cost through years of low energy bills. Larger homes, custom mountain builds, and commercial buildings are especially strong candidates. We'll give you a straight assessment of whether geothermal pencils out for your situation, or whether a high-efficiency boiler is the smarter spend — we'd rather you have the right system than the most expensive one.
Designed and installed as one system
Geothermal only delivers on its promise when the loop field, heat pump, hydronic distribution, and controls are all sized and engineered together. As hydronics specialists, that whole-system design is what we do. We coordinate the loop installation, integrate the heat pump with your radiant and domestic hot water, and commission the system so it runs at the efficiency it was designed for.
Geothermal heat pump brands we install
We install and service the leading ground-source (geothermal) heat pump brands, including WaterFurnace, ClimateMaster, Hydron Module, GeoComfort, Bosch / FHP, and Nordic — and we'll match the right unit to your loop field and home rather than pushing a single brand.

Utility rebates and affordable monthly payments
The federal 25D tax credit for geothermal ended in 2025 — but Utah utility rebates can still take a real bite out of the cost. Rocky Mountain Power's Wattsmart program offers up to $2,000 back on a qualifying heat pump install, and if you're also a Dominion Energy (Enbridge) gas customer, the ThermWise rebate may stack on top of that. We'll help you claim every dollar you're eligible for — call us and we'll walk through what applies to your project.

Serving homeowners and builders across Utah
We design and install geothermal systems throughout the Wasatch Front and beyond — Salt Lake City, Park City & Summit County, Provo & Utah County, Ogden & Weber County, Davis County Weber County Summit County, Heber City, and statewide. Builders and contractors: we handle geothermal scopes for new construction too.
Frequently asked questions
How efficient is geothermal heating?
Very. A ground-source heat pump moves heat rather than generating it by combustion, typically delivering several units of heat for each unit of electricity it uses — far more efficient than burning gas. Paired with low-temperature radiant floors, the efficiency is even better.
Does geothermal work with radiant floor heating?
Yes — it's an ideal pairing. Radiant runs on lower water temperatures, which is exactly what ground-source heat pumps deliver most efficiently. The two are a natural technical match for deep, even, low-cost heat.
Is geothermal worth the upfront cost?
It depends on the project. Geothermal costs more to install but has the lowest running costs over time, so it pays off best on new builds and homes you'll keep long-term. We'll honestly assess whether it pencils out for you versus a high-efficiency boiler.
Can geothermal cool my home too?
Yes. A geothermal heat pump can run in reverse during summer to provide efficient cooling, making it a year-round system rather than heating only.
