Heat Pump Heating

Heat Pumps and Heating

A heat pump is an electrical device that basically moves heat from one location to another. This type of device has been used around the world and in North America. Refrigerators and air conditioners are both examples of a heat pump that is functioning in the cooling mode. However, this heat pump cycle is completely reversible. In this situation, a heat pump can supply your home or building with year-round climate control right through the year despite the weather conditions outside. Some heat pumps even supply heat for your water heater as well.

The process of heating through heat pumps is that they relocate heat by transferring a refrigerant through a series of rotating and alternating evaporation and condensation. A compressor pushes the refrigerant through two heat exchanging coils – the condenser and the evaporator. The evaporator is the coil where the refrigerant absorbs heat from its surrounding environment and becomes a low-temperature vapor. The condenser is the coil where the refrigerant gives off its heat to its surrounding environment and becomes a liquid. In short, the evaporator takes in the heat and the condenser gives it off.

It is not advisable to use a heat pump alone to supply all your heating needs. Generally speaking, this would not be cost-efficient for you. However, if you use your heat pump in conjunction with another source of heating – such as an electric, gas or oil furnace – you have consistent and cost-efficient heating in wintertime and cooling in summer.

It is important to have an assessment done on the insulation of the building before installing a heat pump. If you are losing heat through walls, ceilings, doors or windows which are poorly insulated, there is really no point in spending the money on an efficient heating system. It would be advisable to upgrade your insulation levels to reduce the loss of quality air before installing a heat pump or heating system in your home or building.

Before you purchase a heat pump, it is important to count all the costs involved and weigh all the benefits. Heat pumps would have a lower fuel cost, but are more expensive to purchase than standard heating systems. You must carefully compare your projected savings on fuel with the initial cost of buying a heat pump. In general, heat pumps will be most cost-effective if they are used year-round, so if you intend on using both winter heating and summer cooling systems, it will be more sensible, and even advisable, for you to invest in a heat pump.

Installing a heat pump in your home or building can greatly increase your level of comfort on those hot summer days and cold winter nights.
