Thermal batteries: how to passively store heat

...heated coils from a solar collector. Through that same tank runs another coil that is extracting the heat to pump it through your radiant floor or whatever other heating distribution system you have. Specific Heat Capacity: If you take solid paraffin (heat capacity Cp = 2.5 kJ/kg·K and heat of fusion of 210 kJ/kg),...

...heat pump which will serve as an air conditioner. In effect this will prevent the home from overheating during consecutive sunny days in winter, while producing hot water essentially for free. Heat extracted from indoor air will be transferred to the existing hot water tank, allowing excess daytime heat to be used fo...

...heat , which helps balance temperatures in both summer and winter. Such quantities of heated thermal mass inside the building envelope also provides heat security in the event of a power outage, by slowly releasing its heat over the course of days. Raft slabs can be heated with hydronic systems (liquid) or air-heated...

...heat. We had our zone system designed by our sponsor Uponor which ensured that the heat would be balanced as best as possible. 9: The final floor will be a polished concrete, which is completely non-toxic and very durable. The production of concrete is a heavy polluter, releasing one ton of GHGs (greenhouse gases) pe...

...heat , specifically floors. Walls and ceilings can equally be heated and cooled, it is just much less common. Studies seem to show that there isn't a lot of energy savings reported in homes with heated floors, despite the fact that, in theory, there should be. Radiant floor heat temperatures © Uponor With heate...

Electric Heaters - is heating with electric an eco-friendly option?

Heating with electricity

...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 the same number of...

Ecohome Demo House: High performance, affordable cost

...heat loss rather than complex and expensive heating systems and the utility bills that come with them. When a design team focuses on heat retention rather than heat generation, the net result can be a home that is cheaper to own and operate; not far into the future but right from day one. Added building costs are off...

...heating strategy involves an air-to-water heat pump powered by photovoltaic solar panels that extracts heat from the interior air and transfers it to his water heater, from where it is distributed through his radiant floors. Along with providing air conditioning in summer, this system prevents the home from overheating...

...heating, which offers a very balanced and comfortable environment, transforming the concrete mass into one big radiator. One of the great advantages of radiant floor heat is that the further you get from anything radiating heat (imagine a woodstove), the cooler it gets. So heat is concentrated at ground level where w...
