Hydronic Radiant Heating — A Bitterroot Specialty

Radiant floor heating is highly sought after in the custom home market in north Idaho, but few plumbing subcontractors in the region have deep experience installing it. Bitterroot Plumbing does. We have designed and installed hydronic systems in dozens of custom homes across Bonner County — from simple single-zone PEX systems to complex multi-zone designs with snowmelt, garage heating, and domestic hot water integration.

If your client wants hydronic heating and you need a sub who can handle it from design through commissioning, call us early in the project. We can provide layout drawings and material specs to help with estimating.

Service Territory for General Contractors

We regularly take subcontracts in Sandpoint, Sagle, Ponderay, Kootenai, Hope, Clark Fork, Priest River, and all of Bonner County. We also serve Newport WA, Ione WA, and Pend Oreille County WA. For larger commercial or multi-unit projects, contact us to discuss scope and travel.
