Heat PumpsWhat are they? Heat pumps are devices that pump (or transfer) heat from one area to another. They don't create heat or “coolth”, they just move it. Exup prefers ground source heat pumps, which can be smaller than a regular boiler, and offer both heating and cooling at a low operating cost.
How do they work? Heat pumps have two modes; heating, and cooling. Heat pumps work by pumping a liquid through tubes placed deep in the earth, which maintains a constant temperature, between 50 and 60 degrees Fahrenheit, throughout the year.
The science of heat pumps In the winter, the liquid absorbs heat from the earth and because of its low boiling point, changes into a gas. The gas is then compressed in the heat pump, and the heat is “squeezed” out. The heat is transferred to the home system through forced air or radiant heat.
As the heat leaves the compressed gas it goes through a condenser and returns to liquid form, where it is pumped through the earth tubes again, beginning the cycle anew. Reversing the cycle, where heat is pumped out of the building, is used to cool down in the summer months.
What are the benefits? Because heat pumps use fuel to transport heat and not create it, they can be much more efficient at heating up a building. This translates into less fuel needed, lower operating costs, and as usual when less fuel is needed in a high-threat environment, higher security. Why?
Why does Exup use heat pumps? Not only do heat pumps operate much more efficiently than other active heating and cooling methods, in most cases they are smaller, more durable, and can be safely protected inside a building, shielding them both from environmental and human attacks.
