The three installation types
There are three main installation methods, each with very different cost profiles. In-slab (PEX cast into a concrete pour, new construction or basement floors): the cheapest method per square foot. Staple-up (PEX stapled to the underside of wood subfloor, with reflective insulation): mid-cost, common for upper-level retrofits. Sandwich or panel (PEX in routed grooves on top of subfloor): the most expensive per square foot but highest performance for retrofits.
What's included in our quotes
Our infloor quotes include: LoopCad system design, all PEX-A tubing and manifolds, primary-secondary near-boiler piping, mixing valves, circulators, controls, the condensing boiler (if not tying into existing), and permits. We do not separate out "design fees" or " engineering fees" — they're included.
Add-on zone vs. whole house
A common project for us is adding a single infloor zone (often a bathroom, basement, or addition) to a home that already has a boiler. These projects run $5,000–$10,000 depending on access and tie-in complexity. Whole-house projects run $25,000–$50,000+ depending on square footage and finish floor materials.
How much you'll actually save on operating cost
Infloor radiant typically operates 10–20% more efficiently than baseboard or panel radiator distribution because lower water temperatures (~110 °F instead of 160 °F+) keep the boiler in its condensing range almost continuously. Combined with even, draft-free comfort, most owners say it's the best heating decision they've ever made.
