Installing sub floor radiant heat

This radiant-floor-heating system is relatively easy to install, won't leak, and doesn't cost a lot to operate. Stepping onto ice-cold bathroom tile is a cruel way to wake up in the morning. It's no wonder so many of us invest in extra-thick slippers and giant bath mats. But what if we were able to shed our slippers and step barefoot onto tile that's toasty warm? Radiant-floor heating makes that possible. And you can install it in your home with far less trouble and expense than you might expect.

Radiant-floor heating has been around for centuries. The principle is simple: The floor radiates heat to your feet, warming you all over. Most familiar are hydronic systems that heat your entire house. They produce wonderful heat, but they require serpentine runs of plastic tubing, water heaters or boilers, pumps and manifolds. This makes hydronic systems expensive and complicated to install.

A simpler, less expensive alternative for just a single room is one of the electric systems discussed here. System Basics An electric radiant system consists of thin heating cables, like the wires in an electric blanket, installed under ceramic tile.

Because the cables are so thin they don't raise the level of the flooring much; this makes them great for remodeling. They're installed where warm floors are appreciated: bathrooms, mudrooms, and kitchens. Controlled by their own thermostat, these electric floor heating systems don't replace your main heating unit—they augment it. If you're installing radiant floor heat in an existing room, you'll need a dedicated to amp GFCI-protected circuit to power the system, and an excuse to lay a new tile floor.

If you're remodeling, it's a good time to satisfy both requirements. This electric floor heating system will consume about the same amount of electricity as three W lightbulbs. While you can hire a pro to do a radiant-floor retrofit, it's not a difficult job if you're comfortable setting floor tiles. On the other hand, high temperatures caused by radiators increase discomfort and reduce oxygen levels.

The thermal circulation from air rising to the ceiling and then back gets all the dust going in circles which will not happen with a floor heating system. Underfloor heating is easy to install, especially if you make it part of a build or renovation project. Water-based systems are usually installed during the build phase and incorporated into the construction or renovation project, usually at a cost two or three times that of installing an electric system.

As you usually need to apply a self-leveling compound on top of the electric underfloor heating system, you should factor in the time it takes for this to completely dry before the floor covering can be put in place — this is usually a day or two. Furthermore, you may want to place insulation boards underneath the heating equipment to maximize efficiency potential by ensuring all the heat goes up rather than down.

Insulation boards will increase the height a little further, by approximately an inch. Underfloor heating is an easy and energy efficient way to warm your home and to keep your toes cozy. When remodeling your bathroom , radiant floor heating is especially worth thinking about. You will save a lot on the labor cost if the flooring is being lifted up and changed anyway.

The comfort and the cost savings of running the system on your heating bills will work out to your advantage in a longer run.

Lower Operational Costs The best subfloor insulation will ensure that all the heat generated by the radiant floor system stays inside the room and does not leak away to the concrete or framing below it.

More Reliable, Consistent, and Faster Heating The heater operates by quickly bringing the floor surface to the desired temperature, then clicking off and on only as necessary to maintain that temperature. Environmental Impact Electric radiant floor heating is one the most efficient delivery systems to heat your home. Moisture Prevention Condensation occurs when moisture-laden warm air gives up that water as it cools down in the process of heating up colder air that it comes in contact with.

The Best Subfloor Insulation Subfloor insulation provides cost saving benefits in an electric radiant floor heating system, but is there a board that provides the best value in heat retention, noise reduction and overall operational efficiency?

Lay boards on fresh grooves with staggered joints. Walls Standard wall insulation is fiberglass in batt form and the minimum in most areas is R, with R being standard in many regions. Windows Most windows on the market today are energy efficient, but you can increase their performance by ensuring that the cavity around the window is well insulated.

Doorways Like windows, doorways are best insulated with non-expanding foam which can be easily sprayed into the opening for a great seal. Ceilings Ceilings and attics are two areas that deserve the most attention in your insulation program. All ceilings should be insulated — even between floors inside the home. You can usually insulate floors to a minimum of R with batts, with standard 2x10 framing.

Depending on your region, attic insulation should be R to R This can be accomplished with multiple layers of batt insulation or with a combination of batt and loose-fill blown in insulation.
