Tests can be made to measure the air tightness of a building, to follow air movement, and to locate leaks throughout the home. Airtight houses have dramatically affected how air moves and how it impacts health and comfort. It is important to understand air pressure and the subtle, unseen way it affects the environment inside a house. Check for properly balanced air flow.
Inadequate ventilation can increase indoor pollutant levels and may lead to discomfort and even harmful health effects. STEP Warmfloor® runs on low voltage and there is no dangerous storage of heat sources like gas and fuel, as with boilers and furnaces.
Installing a well-designed separate heating and cooling system provides the best levels of comfort. Cold air has a higher density than hot air. Cold air will fall or sink into the room, while hot air will rise. Initial cost may be a concern, but the comfort benefits and energy savings of separate heating and cooling systems as opposed to a hybrid system far outweigh the price.
Excessive moisture can contribute to a large number of problems, ranging from serious building damage to mold growth. The migration of moisture is determined by the combination of temperature, humidity and air movement. Mold and microbiologic contamination can be controlled with an even overall distribution of heat, as provided by STEP Warmfloor®.
During the heating season, the indoor humidity level should be maintained around 30 to 40 percent. With high humidity level, condensation forms on cold surfaces, while a too dry home will seem colder. STEP Warmfloor® delivers the right amount of heating to a given space and the temperatures can be zoned at different levels with an electronic voltage regulator.
With radiant floors, the heat source is the floor itself and any covering placed over the top of that source may restrict heat transfer. It is therefore important to know the thermal transmission properties of the different floor covering materials. Both thermal conductivity and thermal resistance should be taken in consideration. STEP Warmfloor® radiant heat transmission products provide superior insulation over cold floors and give unparalleled heat transfer from radiant heated floors to floor coverings.
R-value is a measure of thermal resistance of a material in terms of heat transfer caused by conduction and convection. However it does not measure or rate a product’s ability to reflect radiant heat energy. The tests that are used to show the R-factor of insulation may not correspond to the installed R-value. For example, insulation will lose much of its effectiveness with excessive moisture and a 4% void area will cause up to 50% increase in heat loss.
When higher thermal resistance is applied on the radiant floor, compensate by placing more insulation under the heating elements. STEP Warmfloor® is self-regulating and will not overheat.
Our radiant heating solution gives you the option to heat a single room, several rooms or your complete house. You can use our radiant heating elements as the only heat source or as a complementary heat source to get a comfortable and warm floor.
