The Benefits of Using Heat Pump to Heat Your Pool
A heat pump normally offers the lowest cost method of heating your swimming pool. Heat pumps extract heat from the outside air by using refrigeration technology.
They have a built in heat exchanger which transfers the heat captured from the air into the pool water. The heat exchangers are normally made of titanium so that they are resistant to the corrosive effects of pool chlorine on most metals.
Swimming Pool Heat Pumps are Highly Efficient
At HeatPumps4Pools., the swimming pool heat pumps that we sell are highly efficient and have very high COPs
The COP is the ratio of the input power to the output heat to the pool.
Most swimming pool heat pumps deliver around 5-6kw of heat to the pool for every 1kw of electricity they use.
This makes the efficiency of a swimming pool heat pump around 500-600% efficient.
Inverter Driven Swimming Pool Heat Pumps
The latest swimming pool heat pumps now use inverter technology.
Inverter technology allows the fan and the compressor in the pool heat pump to run at variable speeds.
The heat pump can therefore adjust its output to exactly match the demand from the pool.
Once the swimming pool has reached its desired temperature, an inverter driven swimming pool heat pump will reduce its output down to typically around 25% to 50% of its maximum power.
When the inverter driven swimming pool heat pump is running at reduced power, the COPs can reach around 13.
This means that for 1kw of electricity used, 13kw of heat is delivered to the pool.
No other method of swimming pool heating can deliver such high efficiency
At HeatPumps4Pools, we sell a wide range of swimming pool heat pumps that we consider to offer the best combination of price, performance, warranty and after-sales support (eg spare parts availability).
How Swimming Pool Heat Pumps Work
Swimming pool heat pumps provide a very low cost method of heating your pool by harvesting FREE energy from the air and using it to heat your pool
Pool heat pumps use technology similar to air-conditioning units. They use a fan and compressor to take heat from the surrounding air and transfer it to your pool. The fan blows air through the heat pump and in doing so, air is drawn over the evaporator coil (the fins on the rear of the heat pump). This then transfers heat from the air to the refrigerant gas inside the refrigerant pipes.
The compressor compresses the refrigerant gas which causes its temperature to increase considerably. This hot gas is then passed through a built-in titanium heat exchanger which has the pool water flowing around the hot refrigerant gas causing heat to be transferred to the pool water
Energy Savings from a Swimming Pool Heat Pump
For every 1kw of electicity that our pool heat pumps consume, they return approximately 5-6kw of heat to your pool making them around 500% to 600% efficient. Newer inverter driven heat pumps can give up to 13kw of heat for every 1kw of electricity used. The electricity to the heat pump simply powers the fan and compressor. The system takes FREE heat from the surroundng air and transfers it to the pool using the refrigeration cycle to give you a very Low Running Costs to heat your pool.
Installation of Swimming Pool Heat Pumps
Our pool heat pumps are very easy to install. They are completely self-contaned and only need an electrical supply and a supply of swimming pool water to operate. .
We have lots of tips on how to install your pool heat pump on our Installation Tips page
The Refrigeration Cycle
For every £1 that you spend on electricity with a heat pump, approximately £5 will go into your pool. With modern inverter driven heat pumps, this can be up to 14kw of heat for every 1kw of electricity used ! The electricity to the heat pump simply powers the fan and compressor. The system takes heat from the surroundng air and transfers it to the pool using the refrigeration cycle.
YOU PAY FOR 1 UNIT OF ELECTRICITY AND YOU GET UP TO 14 UNITS OF HEAT FREE !!
At stage 1, a unit of electrical energy (you pay for) runs the compressor which sucks evaporating freon gas from the liquid filled evaporator tube. This causes a strong cooling effect (just like sweat evaporates from you skin & cools you off). The gas picks up four units of heat (FREE) from the air flowing over the outside of the evaporator tubes.
At 2 the compressor squeezes this gas, causing its temperature to climb above 200° F (93° C) Result: Five units of heat added to the gas.
At 3 the hot,high pressure gas flows through the inside of the condenser coil. The colder 80° F (26° C) pool water picks up the five units of heat from the freon which cools it down back to a warm liquid.
At 4 the warm liquid is forced through a valve. As it drops in pressure, it rapidly expands and becomes extremely cold liquid .This liquid flows back into the evaporator At 1 where it repeats the cycle
The output of all air source heat pumps is dependent on the ambient air temperature.
As the air temperature falls, the heat output from the heat pump will also be reduced.
It is therefore important that the choice and sizing of the heat pump takes into account the lowest air temperature that it will be required to operate in.
Our sizing advice will take into account the output of the heat pump at the lowest air temperature.
