Whole-Home Radiant Floors Questions

PEX tubing in a hydronic system can last several decades. Boilers, pumps, valves, and zone controls typically need replacement sooner. Longevity depends on installation quality, regular maintenance, and the condition of the heat source. A post-install check and annual servicing extend the working life of every component.

An undersized system will run continuously on the coldest Boulder nights and still fall short of the target temperature. At altitude, a boiler without derating applied can lose meaningful output. Correcting sizing after installation means replacing the heat source, a cost far higher than getting the calculation right before the project is scoped.

PEX-A is more flexible and handles tight bends without kinking, which suits complex loop layouts. PEX-B is stiffer and often lower cost, working well in straighter runs. The right choice depends on the loop layout, floor construction, and the installer’s assessment of each zone’s routing requirements.

Both are viable. New construction is simpler because tubing is placed before finish flooring. Remodels require a room-by-room check of existing floor build-up to confirm door clearances and transitions can be maintained. The written scope addresses this for every room before work begins.

Most homeowners reduce or shut down the system when it is not needed. The right approach depends on your controls and system setup. The main goal is avoiding unnecessary runtime while keeping the system ready for the next heating season, your installer will confirm the recommended procedure for your specific configuration.

Pricing is typically based on square footage, but the total depends on system type, floor construction, heat source, and whether it is a new build or remodel. An itemised written estimate is prepared after the site assessment, so you see the full breakdown before committing to the project.
