What Is a Water Source Heat Pump?
Water source heat pumps (WSHP) move heat from a source of water to
your household more efficiently than any other heating and cooling
technology. A river or a small stream can be pumped through a heat
pump, and it can deliver excellent results, especially if the water
temperature is somewhere around 5 to 8 degrees celsius. This kind
of technology has been used since the late 1940s. Water source heat
pumps use the rather constant temperature of water as an exchange
medium instead of extracting the heat from the outside air
temperature. Thus, the system can reach reasonably high
efficiencies (300% to 600%) on the coldest winter nights, in
comparison to 175% to 250% for air-source heat pumps on cool days.
How Do Water Source Heat Pumps Work?
The system is made of fairly efficient reverse cycle heat pump
units which are interconnected by way of a water loop. Every unit
offers specific air comfort requirements in the particular zone
they are installed. During cold weather, the heat pumps transfer
heat from a water loop through the unit’s specially designed
refrigerant-to-water heat exchanger and then move it into the air.
In extreme weather conditions, when a lot more heat is necessary to
warm up the building, units are operating in heating mode, hence
heat is provided to every individual unit from the water of the
loop. In case there isn’t enough heat in the loop water, an energy
efficient fluid heater must be installed in the loop in order to
assist the heating process.
Ideally, the water source should be close to the house, so that it
would not need to be pumped up at any significant height or the
energy required for pumping could be decreased, thus increasing
your savings. Water can be sourced from substantial distances if
the pipe diameter is adequately big, especially in a downward
direction. When considering installing such a device, you must take
into account the permissions and paperwork that must be completed
in order to start your installation.
Save Money With A Ground Source Heat Pump
At a 300% efficiency rate, a ground source heat pump will prove a
cost efficient as well as an environmentally friendly investment
that will help you save up to 40% on heating bills compared to
conventional heating systems. Among its advantages are the pump's
- cut your heating bills in half.
- last for around 25 years (indoor components) and 50 years (for the
- ensure a more equal distribution of heat.
