HEAT PUMPS – WHICH TECHNOLOGY
With the aid of a ground source heat pump, solar energy stored in the ground can be collected and used to heat your home. Often referred to as geothermal heating, the heat collected is mostly from the sun in fact and not the earth’s core.
Warmth builds up underground from the first days of spring when the surface temperature of the earth starts to increase, to high summer, when the rays of the midday sun penetrate down into the ground. Warm rainwater also permeates the upper layers of the ground. By the time the autumn leaves are falling, there’s enough energy stored in the ground to heat up your house throughout the coldest winter. A heat pump captures and upgrades this naturally occurring warmth, so even if the summer seems wet and cool, it can still provide enough energy to maintain a comfortable indoor temperature throughout the coldest winter.
