What Goes Wrong
Where whole-home radiant installs fall short, and how to avoid it
Skipped Insulation
Without insulation board below the tubing, a significant share of BTU output escapes downward into the subfloor or slab instead of heating the room.
Insulation Board First
Rigid insulation board is placed below every loop so heat moves upward into the living space, not downward into the structure.
Undersized Heat Source
A boiler or heat pump sized for sea level loses output capacity at Golden’s elevation, leaving rooms short of their design temperature on the coldest days.
Altitude-Derated Sizing
The heat source is sized after a heat loss calculation that accounts for elevation, so the system meets its BTU target on the coldest nights of the year.
Wrong Tubing Choice
PEX B is lower cost but less flexible, making it harder to route through tight subfloor cavities without kinks that restrict flow and reduce heat output.
PEX A for Tight Runs
PEX A tubing bends without kinking and is the standard choice for above-subfloor installs where routing through framing bays is unavoidable.
No Zone Controls
A single-zone layout heats every room to the same setpoint, wasting energy in unoccupied spaces and making it impossible to balance comfort across the house.
Room-by-Room Zoning
A hydronic manifold with individual zone controls lets each area run its own schedule, so bedrooms, living spaces, and utility rooms are managed separately.
System Scope
What a whole-home hydronic system covers
Every component from heat source to finished floor, sized and laid out for the full house.
Heat Source Selection & Sizing
Condensing boiler or heat pump matched to the home’s heat loss calculation and altitude-adjusted BTU load.
Hydronic Manifold & Zone Controls
A central manifold distributes heated water to each loop, with individual thermostats controlling every zone independently.
PEX Tubing Layout & Installation
PEX A loops spaced 9 to 12 inches apart are embedded in slab or stapled above the subfloor under every room.
Subfloor Insulation Board
Rigid insulation placed below the tubing layer directs heat upward and improves system efficiency across the whole house.
Floor Finish Compatibility Review
Tile, engineered hardwood, and concrete are confirmed compatible with operating temperatures before tubing is laid.
New Construction Install
Tubing embedded before the slab is poured or subfloor is closed.
Open-Floor Remodel Install
Loops laid while floors are already open, minimizing disruption.
Slab-on-Grade Embed
Tubing cast directly into the concrete slab for maximum efficiency.
Full-House Scope
Whole-home radiant floors: sizing, insulation, and why new builds are the right window
A whole-home hydronic system heats every room from the floor up, with no ductwork and no cold zones.
A whole-home hydronic system starts at the heat source, a condensing boiler or heat pump, and runs through a manifold that feeds individual PEX loops to each room or zone. PEX A tubing is more flexible and easier to run through tight subfloor spaces than PEX B, making it the common choice for above-subfloor installs. Insulation board placed below the tubing prevents heat from escaping downward, keeping the BTU output directed at the living space.
Upfront cost and floor height change are the two objections that come up most often. A whole-home hydronic system costs more to install than a forced-air system, but operating costs are lower over time because radiant heat cycles less frequently and distributes more evenly. Floor height increases by roughly 1.5 inches for an above-subfloor install, a detail that matters for door clearances and transitions, and one that is addressed in the written estimate before any work is scheduled.
New construction and open-floor remodels are the lowest-disruption window to install. When floors are already open, tubing can be laid without tearing up finished surfaces. Slab-on-grade construction common in parts of the Golden area suits embedded hydronic tubing particularly well. Delaying past the point when floors close means a significantly more disruptive and costly retrofit later.
Why Choose Us
Why Mountain Radiant Heat for whole-home radiant floors?
Whole-house scope requires a process that accounts for every room, every zone, and the specifics of your build, before a single loop is laid.
Evaluation Before Estimate
Every enquiry starts with a load and equipment check, so the written estimate reflects the actual job.
Altitude-Adjusted Calculations
Heat loss and BTU sizing are run for Golden’s elevation, not a generic sea-level figure.
Itemised Written Estimate
Equipment, installation scope, and timeline are documented in writing before any work is booked.
Post-Install Performance Check
After installation, the system is tested to confirm it performs to the specified output and zone settings.
Vetted Local Partners
Enquiries are connected to independent local installers who work the I-70 mountain corridor regularly.
Questions homeowners ask before committing to whole-home radiant floors
Can radiant floor heat realistically cover an entire house?
Yes. The key is planning each room as its own zone, sized to its heat load, and running all circuits back to a central manifold. That layout is what makes even heat across every room achievable rather than theoretical.
Will the floor height change noticeably after installation?
It can add height, but the amount depends on the tubing method, insulation underlayment thickness, and the final floor covering. Floor buildup is calculated per room before any work begins, so doorway clearances and transitions are confirmed upfront, not discovered after the fact.
Does radiant floor heat work in an older Colorado ranch-style home?
It does, but older homes often need more subfloor prep before tubing is placed. Subfloor condition is assessed first, and the tubing method -- staple-up, thinset embed, or sleeper -- is chosen based on what that specific floor can support.
What happens if I delay addressing uneven heat or cold floors?
Continuing with forced-air or spot heating through another Golden winter means the underlying problem -- poor heat distribution -- stays in place. Cold floors and drafty rooms also put more load on an existing system, which can shorten its service life.
What checks are done before the system is turned on?
Every loop is pressure-tested after tubing placement and before floor covering goes down. Zone valves and thermostat wiring are verified, and the system is brought up gradually at startup so each zone’s output is confirmed before the project is closed.
How disruptive is a whole-home installation in an occupied house?
Disruption depends on the subfloor method and how many rooms are done at once. The written scope outlines the sequence room by room and the timeline for each phase, so you know which areas are out of use and for how long before work begins.
