Heating with Heat Pumps

Heating with Heat Pumps Heat Pumps can be a very economical way of heating and cooling your dwelling depending on geographical location and the cost of electricity in your area. The volatile costs of natural gas, propane, and oil has enabled these conditions where it can be cheaper to heat with a heat pump than with fossil fuels. There is a common conception that a heat pump blows cold air and while this can be true in some cases it is not true to all heat pumps. If a heat pump is blowing cold air when in the heating mode then it needs to be looked at because there exists a problem that needs to be corrected. Even when the outside unit kicks into the defrost mode the unit should provide adequate heat to heat the zones which it serves. Again, if it is not providing adequate heat then it needs to looked at for a technical problem that needs correcting. A well designed heat pump system, working properly and efficiently, can provide competitive and economical heat for your dwelling
