Heat pumps can extract heat from either the air or the ground, for providing central heating in buildings. This is a cheaper, more sustainable method when compared with current central heating systems that require oil or gas.
Air source heat pumps absorb heat from the air. In principle, they
work exactly like refrigerators, except that they extract heat from the outside;
a refrigerator extracts heat from the inside.
Air source heat pumps work best with proper wall cavity and loft insulation, and when combined with ground source, can be extremely effective.
Ground source heat pumps work on the same principle as air source, in that
that extract heat from the outside. Much heat is stored in the ground, and can
be readily used. These operate effectively for underfloor or air heating systems
(radiators) in your home or business.
Pipes will be installed beneath your garden, in what is known as a 'ground loop'. The bigger the garden, the more effective the system can be. The best part about ground source is that underground temperatures remain relatively constant on an annual basis, so even during the cold Winter, they can be effective.
There are already companies and organisations that heat their buildings
with this type of technology. The price of renewable energy in general,
including heat pump technology, has fallen dramatically over the years.
Not only that, but they have also become more efficient. The best thing
that any discerning home owner can do, is invest in renewable energy. These
products are safe, reliable and extremely efficient. Not only that, they are cheap.
The initial investment cost pales in comparisons to the savings on energy bills that
can be made. In so many cases, bills are even wiped out completely, so much
so that energy is generated in abundance, to the point of excess.
