Types of Underfloor Heating
Underfloor heating is a type of heating that is considered central type of heating because it provides indoor climate control to make the home more comfortable. Underfloor heating can heat a home using three different types of heat production: conduction, convection, and radiation. The phrase radiant heat or radiant heating is often times used to describe this type of heating because radiation creates a great deal of the heat produced for purposes of comfortably heating a house. Even though the term radiant heat is sometimes used to describe all underfloor heating, not all underfloor heating technology uses radiation. Underfloor heating actually has a long history that goes back before electricity even. Archelogists have discovered in Asia that create tunnels to allow drafts of smoke through these tunnels covered with stone underneath floors of terraced homes. The smoke from fires heated the stones, and this would heat the ancient homes. Underfloor heating has evolved over the […]
How Efficient Is A Geothermal Heat Pump?
Geothermal heat pumps or GeoExchange have been used in homes since the 1940s. This type of heat pump is earth-coupled, water-sourced or ground sourced. This type of heat pump uses the temperature of the ground or water as a means of collecting or exchanging heat instead of using the air as a means of collecting or exchanging heat. Since the ground and water holds a steadier temperature than air does, this type of heat pump is 300 percent to 600 percent more efficient than an air-sourced heat pump especially on a bitterly cold winter day. There are temperature extremes all over the world. In some places the summer sees excessively high heat and in other regions winters are bitterly cold reaching well below zero. These temperature extremes really only exist on the earth’s surface, and just a few feet below the ground the temperature of the earth stay fairly consistent most of the time. Depending […]
