With a water source heat pump you collect energy from the water in a lake, river, sea or just from the groundwater in the ground. This solution can be the right alternative for you that have water or groundwater readily available near your house.
The technique of the water source heat pump is similar to the alternative solution - ground source heat pump, with vertical and horizontal loops. Another alternative to a water heat pump is the air source heat pump.
The ground water is pumped up to the water source heat pump from a water borehole to a heat exchanger, where the energy is recovered. The water is then discharged back through another well.
The benefits of a water source heat pump with a vertical loop are that the solution gives you high and even temperature from the groundwater all year round. By using a water source heat pump you will therefore have the opportunity for passive cooling, i.e for cooling your house in the summer.
With a water source heat pump you collect the solar energy in a lake by using a large tube which is placed on the bottom of the lake. This tube is then weighted.
How long tube you need depends on the size of the house and which capacity of the water source heat pump you choose.
The benefits of a water source heat pump with a horizontal loop are that you don't need to drill and get minor impact on your plot. The solution also gives you high and even temperature from the groundwater all year round. By using a water source heat pump you will therefore have the opportunity for passive cooling, i.e for cooling your house in the summer.
