Radiant Floor Heating in Las Vegas, NV

Winters here are mild and short, with cold nights and mornings. Most homes already have ducted heating that shares equipment with the air conditioner, so tearing into finished floors to add whole-house radiant heat is rarely the practical choice. These are the cases where it earns its place:

• Bathroom and kitchen remodels. Electric mats under new tile are the most common radiant job. The floor is already coming up, the area is small, and warm tile on a cold morning is the whole point.
• New construction and additions. Hydronic tubing is far easier to place before a slab is poured than after.
• Rooms the ducts do not reach. A converted garage, workshop or casita qualifies, though a ductless mini split both heats and cools such a space and deserves a comparison.

Most valley homes sit on concrete slabs. Adding hydronic tubing over an existing slab raises the floor, which affects doors, cabinets and transitions to other rooms. A slab also stores heat for hours, so on days that start cold and warm up quickly by afternoon, the controls have to anticipate the swing or rooms overshoot.

Design comes before materials. We calculate the heat each room loses, then set tube or cable spacing, water temperature and zoning from that. Floor covering is part of the calculation: tile and stone pass heat readily, thick carpet and pad hold it back, and wood floors need a limit on surface temperature to avoid damage.

For hydronic systems we lay out the loops, connect them to a manifold, and pressure-test the tubing before concrete or flooring covers it. The heat source, pump, expansion tank, air separator and mixing controls are sized to the loops. Insulation under a heated slab and around its edge matters as much as the tubing, because without it a good share of the heat goes into the ground.

For electric systems we measure the heated area, leaving out the space under cabinets, tubs and toilets, test the cable's resistance before and after the tile goes down, and wire it to a thermostat with ground-fault protection on a correctly sized circuit.

Typical hydronic problems are a zone that stays cold, gurgling from air in the lines, a failed circulator pump or zone valve, a drip at the manifold, or system pressure that keeps dropping. A closed loop should not need regular topping up, so falling pressure usually means a leak. When tubing in a slab is suspected, we narrow down the location with pressure testing and thermal imaging before anyone opens the floor. Our leak detection page explains the methods. With electric floors the usual culprits are the thermostat, the floor sensor, or a cable damaged during a later remodel.

Hydronic systems should be checked once a year, ideally in fall: heat source serviced, pressure and expansion tank verified, pump and valves operated, air purged, and the condition of the system water tested. Electric systems need little beyond pressing the thermostat's test button now and then. Either way, tell anyone drilling or nailing into a heated floor exactly where the heat is.

Call 702-497-0888 and describe what you have or what you are planning. For a new floor the best moment is early, before the tile is ordered or the slab is formed, so the heating can be designed in. For an existing system, tell us which type it is and what it is doing. Our licensed technicians and plumbers serve Las Vegas and nearby Clark County communities, with 24/7 emergency service for leaks and loss of heat. If another kind of heating would serve you better, we will say so.
