So, why radiant floor heat?
Radiant floor heat is the most comfortable heat available. Warmth stays near the floor warming our bodies and the objects surrounding us. The heat energy that we pay for doesn't rise to the ceiling as with forced air heat, escaping through the ceiling or through open doors.
Why does RMS refer to only basements and garages?
Radiant floor heat is most effective in concrete floors that are either at ground level or below the ground. Garages and basements commonly meet these conditions and have relatively well-defined heat loss. Less common applications include home additions, workshops, storage sheds, small commercial buildings etc. Such structures may have more widely varying heat loss. For such applications contact us with a description of your plans. We are happy to help you choose the appropriate product.
Can radiant floor heat be added later?
Unfortunately, there are no low-cost ways to add radiant floor heat to an existing concrete floor. If you are building, now is the time to install radiant floor heat.
What if I want to heat a framed floor?
Radiant Made Simple relies on high mass material such as concrete to act as a radiator to distribute heat to the occupied space. Without the high mass material, more complex strategies not appropriate for do-it-yourself installation need to be employed.
What if I want more than one temperature zone?
For simplicity, individual RMS units are recommended for each zone. Zoning a concrete radiant floor will require framing thermal barriers between zones before concrete is poured. Otherwise, the efficient heat conductivity of concrete will blend temperature between zones.
What if I want to heat both my basement and garage?
Separate RMS units are recommended.
What tube spacing is appropriate?
Spacing depends on several variables including the heat loss of an area. In residential areas such as basements, 12-inch spacing is most common. It is helpful to space the first few tubes closer together in an area at ground level as in a basement walkout area where heat loss is greater. Likewise, spacing can be wider where heat loss is less, as where the floor is several feet under the surface of the ground, or in the center of a large space.
Do I need to insulate the concrete floor?
Insulation is critically important to keep from losing heat to the outdoors by conduction through the earth, the foundation or adjacent walls. When the radiant heated floor is not insulated adequately, it may cause dramatically increased energy cost. Also, the heating unit may not have sufficient output for the unintended heat loss.
Why would I choose electricity instead of gas to heat my floor?
Standard water heaters are rarely better than 55% efficient while the Seisco Electric Micro-Boiler is 99% efficent. Why pay for a lot of energy that goes to waste up the chimney or flue? Incidentally, with electric heat you don't even need a chimney, a vent or a flue.
Is electric heat affordable compared to gas?
You decide, depending on your electric rate. Generally, electric rate increases have not approached the continuing steep rise in propane, natural gas and fuel oil prices. Examples: If electricity costs you 5¢ per kWh it would compare to propane at 81¢ per gallon, natural gas at 88¢ per Therm or fuel oil at $1.13 per gallon. Or, if you pay 8¢ per kWh for electricity it compares to propane at $1.29 per gallon, natural gas at $1.41 per Therm or fuel oil at $1.80 per gallon.
What if I want to heat a floor larger than 1800 square feet?
In many cases more than one RMS unit is the answer for the Do-it-Yourself project provided the heating needs are relatively simple. Otherwise, see the "Not so Simple?" page.
How are RMS products shipped?
Radiant Made Simple products are shipped by Federal Express, United Parcel Service or by SpeeDee in the region that they serve. When requested, shipment by motorfreight is available.
