heat pumps for space heatingA heat pump is a mechanical device that transfers heat from one environmental compartment to another, typically against a temperature gradient (i.e. from cool to hot). In order to do this, an energy input is required: this may be mechanical, electrical or thermal...
LG's heat pump technology provides greater energy efficiency than conventional vented dyers, using less energy with every load. Easy Installation Due to the ventless design of heat pump dryers, there’s no need to create ventilation, so dryer installation could be as easy as plugging it in. ...
efficient home heating on all but the coldest days. When the temperature outside drops too low for the heat pump to operate effectively, the system will instead use the furnace to generate heat. This kind of system is often called adual fuel system– it is very energy efficient and co...
