CHOOSE YOUR RMS MODEL ACCORDING TO THE SPACE YOU WISH TO HEAT IN YOUR BASEMENT OR GARAGE
Whether you are heating your basement or garage, the same RMS model will usually accommodate a similar floor space even though a garage floor at ground level requires more heat per square foot than a basement floor several feet below the ground level. This is influenced by the fact that the typical temperature maintained in a garage is about ten degrees cooler than the temperature required for comfort in a basement living area. The following charts will guide you in selecting the appropriate RMS model. If you have concerns about which RMS model will be best for your particular application, please contact support@radiantmadesimple. We are here to help you.

NOTE: It is the customer's responsibility to verify that sufficient electric service is available before ordering an RMS system. If a customer orders a system and upon receipt decides that it cannot be used, Radiant Made Simple will authorize return, refunding the system price less a 20% restocking charge. Shipping costs are not refunded.
AREAS LARGER THAN 1800 SQUARE FEET? NO PROBLEM
Areas larger than 1800 square feet should be subdivided and served with two or more RMS units sized for each area. EXAMPLE #1: A 2500 square foot basement could be treated as two 1250 square foot areas each served by one RMS11-4. EXAMPLE #2: Two temperature zones are desired in the 2500 square foot basement, one 760 square foot zone could be seved by one RMS7-2 and the remaining 1760 square foot area served by one RMS11-5.
If you already have 1/2" PEX floor loops installed, order the RMSx-xxLT models. They are supplied without radiant floor tubing. TIP: The last digit in the model number indicates the number of radiant floor loops that the unit is equipped to serve. (The RMS7-3LT serves three loops)
YOU MAY QUALIFY FOR LOWER ELECTRICAL RATES WHEN HEATING WITH RADIANT MADE SIMPLE
Some electic utilities offer a reduced electrical rate in exchange for the right to interrupt the power to the Micro-Boiler in your RMS system. Contact them for information and details. If their program calls for interrupting your power for short periods (such as 4 hours) you will scarcely notice any drop in temperature because of the storage characteristic of radiant floor heating. The floor continues to radiate heat after the power is turned off.
Some electric utilities interrupt power for longer periods, such as 12 hours on/12 hours off. This will result in more significant reduced room temperature. Should you decide that you can tolerate the fluctuation in temperature, you would need to nearly double the capacity of your RMS system for the room temperature to "catch up" after the long power interruption.

DISCLAIMER
The design of RMS systems is consistent with generally accepted building practices. System sizing assumes that there is adequate insulation under the concrete slab, around its perimeter and edge, and that the walls and ceiling of the space to be heated are well insulated. It is also assumed that the heat loss of the structure does not exceed 20 BTU/sq. ft. which is consistent with basements and garages in the coldest parts of the continental US. These systems are specifically not intended for residential living spaces above ground or at ground level where building envelope construction is subject to considerable variation. RMS systems may be used in such applications if sized to accommodate actual heat loss and when installed properly.
