Heating a Swimming Pool - Top 10 Cost-Efficient & Eco-friendly ways to heat a pool

...Heat pump pool heaters are really energy efficient and the energy efficiency of a heat pump pool heater is measured by the coefficient of performance (COP). The higher the COP for the pool heater, the more energy efficient it is. Typically, COP is measured by testing a heat pump pool heater with an outdoor temperature ...

...passive solar design is that much of the heating load is carried by the heat coming in the windows, with energy modeling suggesting that about 30% of the house's total heat load is being passively provided by the sun. The final thing that always needs to be mentioned when discussing a building envelope is air-tightne...

Thinking about renewable home energy and a battery backup?

...passively-heated homes, it's really just a traditional wood stove that will save your bacon (or help you cook it) when the power is out. A photovoltaic (PV) solar array that is designed to run the basic systems of your home, excluding heat, likely wouldn't be enough to heat your whole house if you diverted power to h...

...heaters: large stone masonry heaters are very expensive, but they are a very efficient way to heat with wood. While a wood stove provides heat primarily when burning, a fire in a masonry heater warms the mass of stone, which then releases heat over many hours or even days. Due to its thermal mass and greater extraction...

...heating needed for this home is accomplished by sun streaming in the windows. I've taken just enough of a look at the passive solar heating literature to know that this is roughly as high as one should go with passive solar heating in a home unless one is willing to endure unwelcome overheating on warm sunny days in ...

...passive heat gain in living spaces. To know if that's really a good idea for the planet, you would need to realistically calculate how much food you could produce in that space compared to how much heat could have been passively generated and decide which improves your carbon footprint. We would argue for the heat ga...

How much insulation is too much in attics and walls?

...heat, they need to ADD less heat. And sometimes…not all the time but sometimes… that can also mean reduced costs in heating and cooling infrastructure. What that in effect means, is that rather than buying a big furnace to heat a poorly insulated house, it's possible to buy a small furnace to heat a well-insulated hous...
