Residential earth-water geothermal heating pumps home
GHP26-DNNNE, designed and tested by European standard EN14511, approved and tested by TUV china branch. Characterized by its high COP, competitive price and perfect quality.
HISEER GHP26-DNNNE, ground source heat pump, works by using heat stored in the ground from the sun's solar radiation to supply all of the energy required for a home's heating and hot water system.
HISEER geothermal ground source heat pump adopts the following world famous parts:
|
How it works |
|
1.The ground loop This is comprised of lengths of pipe buried in the ground, either in a borehole or a horizontal trench. The pipe is usually a closed circuit and is filled with a mixture of water and antifreeze, which is pumped around the pipe absorbing heat from the ground. The ground loop can be: •Vertical, for use in boreholes •Horizontal, for use in trenches •Pound/Lake installation |
|
2.A heat pump In the same way that your fridge uses refrigerant to extract heat from the inside, keeping a ground source heat pump extracts heat from the ground, and uses it to heat your home. |
|
3.Heat distribution system |
