Ground source heating is pure solar energy.
This is because solar heat is stored in the ground.
First on the surface, as you tidy up your garden in the spring.
Then further down, as you spend the summer evenings in your hammock.
And when you're brushing up the last of the autumn leaves, enough free energy has been stored to heat your house even in the coldest winter.
Perhaps we should add one thing.
Even the most miserable summer will be warm enough for sufficient heating energy to be stored beneath your land.
The collector brings up the heat.
Using a hose filled with liquid, known as a collector, you can bring up solar energy stored deep down in the rock, at the bottom of the lake or a metre or so beneath your lawn.
The one collective term "ground source heat" is often used to cover all three sources of heat, that is, rock heat, surface soil heat and lake heat.
The specific heat source that you should use is decided by the house's energy needs, your heating system and the nature of your plot of land.
The heat pump concentrates the energy.
It is the heat pump that concentrates the stored heat energy in such a way that it can heat the water, in both showers and radiators.
This is how it works.
The liquid in the hose circulates and is heated up by the stored solar heat down
in the ground or in the lake.
When the liquid passes up into the heat pump, it meets another closed system.
This contains a refrigerant that can turn into gas at a very low temperature.
Under high pressure, a compressor considerably increases the temperature of the refrigerant, which is now gaseous. Then, using a condenser, the heat is transferred to the house's heating system, while at the same time the refrigerant reverts to liquid form, ready to turn into gas once more and to collect new heat energy.
The result is the main thing
The principle behind ground source heating is basically very simple, but as we have developed the technology down the years, we have created increasingly sophisticated and advanced products.
In parallel with this, our heat pumps have become increasingly simple to install and use.
In effect, they look after themselves, year after year.
What Sigma and NIBE can offer now is a level of performance that guarantees both safe operation and astonishing savings. In terms of both heating costs and the environment.
We, Sigma and NIBE, have the right solution for all needs and for all properties.
