Radiant heat / Guides

...heat loss. Contrary to common beliefs, heat does not rise. Warm air rises, but heat goes everywhere. You need only pick up a hot coffee in a ceramic mug to answer this question for yourself. Does all the heat come out the top? Is it cold on the bottom? Absolutely not. Heat radiates from all sides, including the bottom....

...heat throughout the house. You can find out more about Ecohome's LEED V4 Platinum Edelweiss House , Radiant floors , slab on grade construction step by step , Raft slabs for building on soft soils , and anything else about sustainable green home construction in Ecohome's green building guide pages.

...heat pump to heat the air of the house. This gives us air that is heated on average three times more efficiently (and three times cheaper) than had we relied on electric resistance heat in the form of baseboard heaters or our radiant floor boiler. We also have an air-to-water hybrid electric heat pump hot water heate...

...heated by those solar panels in winter, when the sun's angle is lower, will be fed into the floor heating radiant system, which will reduce the energy demand on the heater coil. Conversely and cleverly, in summer if the heat isn't needed in the house, the heat is diverted to an air/water heat exchanger for heating the ...

...heating, electrically-heated mats are sometimes installed below the tiles in bathroom floors for added comfort. What you don’t see a lot of, are floors heated with air. Electric wire radiant floor heating © Ecohome How to make air-heated floors work: Since the first forced-air heatin...

...heat pumps in this house, an air-to-air heat pump that extracts heat from outside air to heat inside air, and an air-to-water heat pump. The air to water heat pump extracts heat from ambient air inside the home and transfers it to the hot water tank, offering efficient air conditioning in summer. As for heat storage,...

...heat gain and the heat normally generated though human occupancy. This will be the first winter for the Kenogami House, and its performance will be closely monitored. Should it be necessary to take measures to avoid overheating during mild periods, Alain is considering an air-to-water heat pump to extract heat from t...

...Heating during off-peak hours: If you rely on radiant heat from thermal mass such as heated concrete floors, this can make heating with electricity a more realistic option in regions with high peak rates. A radiant floor can be charged with heat overnight during low rate hours, and timed to stay off during peak rate ho...

...heat movement and insulation is a bit like that. The cold hard facts about heat loss: Yes, a bit more heat is lost through the ceiling than the walls, but not nearly as much as much as you might think. The rate of heat loss from any surface of your home depends on the difference in temperature, and it just isn't ...

...radiant floors: Heating cables can be run under both tiles and engineered hardwood. This is not a cheap system to install, but it is a very comfortable way to deliver heat. Radiant in-floor heat can also be achieved through hydronic heating systems , which when heating with water from an electric boiler again offers ...

...heat load based on your specific climate, building envelope, air-tightness, and then design a system to meet those needs. Radiant heating: There is seemingly endless debate in green-building circles as to the comfort benefits of radiant heat , specifically floors. Walls and ceilings can equally be heated and cooled...
