How do ground source heat pump works?
The earth absorbs and stores heat from the sun year after year so that it can provide us with a constant source of naturally renewed energy. Just a few distance under the ground, there is a constant average temperature of 4°C to 12°C. This stored energy is ideal heat source for your daily domestic heating demand.
The ground source heat pump collects heat from the solar energy stored underground, rock, ground water, lake, etc. The heat is transferred from ground to heat pump by the secondary refrigerant which consists of water and an environmentally-friendly anti-freeze solution. It circulates through the closed loop, collecting heat from the ground and transferring to the heat pump.
The refrigerant circulates in the heat pump, absorbing the heat from the ground stored in the secondary refrigerant and converts it into high grade heat to be released to your house by under-floor heater or radiator and into your domestic hot water tank.
1. The solar energy stored in the rock at the bottom of the lake or ground water can be brought up by a collector which is a house filled with mixture liquid of water and antifreeze. The liquid circulates in the hose collects the stored solar energy and is warmed up.
2. When the liquid go through the evaporator of heat pump, it seems another closed refrigerant system. The refrigerant can absorb the solar energy in the liquid and turn into gas at very low temperature.
3. The gas refrigerant is compressed and turn into very hot and high pressure, then the heat is transferred to the water-based heating system in the house by a condenser.
4. Then, the refrigerant reverts to low pressure liquid and ready to collect new solar energy.
Suoher ground source heat pump makes heating your house and domestic hot water much cheaper. It saves your 60% heating cost compared with the traditional heating elements like electrical heater, gas/fuel boiler, wood-fired boiler. The reason for this is that a ground source heat pump uses the free energy from natures.
Although the heat pump can not pay you back in the first month, you will notice the benefits soon since the heating bill is dramatically lower than before. The high efficiency of Suoher heat pump makes you get back the investment faster. In fact, it saves money for you as soon as you finish the installation and cycle it on.
By absorbing free & green energy stored in the ground, surface soil or lake to heat your house and domestic hot water, it makes much lower Co2 emissions than any traditional heating system such as gas boiler, wood-fired boiler.
Wherever you live, you can install a water to water heat pump and enjoy efficient, safe, problem-free, heating and hot water at a fraction of the alternative cost and a fraction of the environmental impacts.
FAQs of Suoher Ground Source Heat Pumps
1. Can ground source heat pumps be used in cold weather?
In the harsh winter, even if the surface temperature reaches below -30 degrees, the temperature under a certain depth of soil can still reach around 10 degrees. At such temperatures, the COP of ground source heat pumps can still reach 2.0 or above, providing customers with stable and reliable heating and hot water. In harsh cold areas, the energy efficiency and operational stability of ground source heat pumps are far superior to air source heat pumps, making them the best choice for heating.
2. How high can the outlet temperature of a ground source heat pump reach?
Even in the harsh winter, the outlet temperature of ground source heat pumps can reach 60 degrees, which can meet your heating and domestic hot water needs.
3. In which countries and regions can ground source heat pumps be used?
Ground source heat pumps can obtain heat sources through groundwater, soil, rock formations, lakes, and other means, so they can be used in many scenarios and can be used in most countries and regions around the world.
