Heat pumps that use water as their source of heat and heat sink are called water-source heat pumps. In contrast to geothermal heat pumps, or ground-source heat pumps, in these systems water is used as a medium of direct transfer of heat. The water source can be groundwater filled extraction wells, in which case it is a open loop coupling system, or a pond, stream or lake, in which case it is a closed loop coupling system.
Cast iron radiators are used in hydronic (hot water) and steam heating systems. They transmit heat by both convection and radiation heat transmission. Air contacting the heated iron surfaces becomes heated through convection, then circulating through the room. Warmed air radiates out into the room air as well. Most modern radiators use hot water
Radiator modules are constructed by joining together a series of hollow vertical sections, each section having a waterway opening at the top and bottom. Metal round fittings and gaskets are attached to the openings to form passages, through which hot water or steam flows. The number of section used varies depending on the size of the space to be heated and configuration of the room, window placement, etc.
Although you might think it a waste of money to start heating your crawl space – it is actually something that could save you money in the long run. Having said that, anyone living in a relatively warm and dry area might then think that heating crawl space won’t apply to them, as it will only be necessary to prevent heat loss through a floor.
Well, the reality is that unheated crawl spaces in areas that air conditioning is used regularly, can be in just as much need of heated crawl spaces as colder regions. The reason for this is not just to do with heat control and efficiency but – moisture.
Once thought to be only economically viable for energy utility companies to install, there are now residential geothermal heat pumps available that are suitable for new properties or can be retro-fitted to older buildings.
Propane is a commonly used fuel alternative. These are some ways to make a propane heater safe to operate in your home. Propane is stored and transported as a very cold liquid. So cold that it can cause frost bite if exposed to your skin. In this page we cover safety tips for indoors propane heaters.
Propane tanks are constructed from carbon steel. They are incredibly puncture resistant. They come with a device that shuts down filling when the tank is at 80% capacity. This is to allow for pressure change that occurs with changes in temperature. Propane tanks are often painted white or silver in order to reflect heat and prevent severe pressure changes.
