A heat pump for a swimming pool is a fantastic and cost effective method to heat your swimming pool.
There are a number of alternative ways to heat your swimming pool ranging from gas and oil burners to wood burners. Despite having these options that are available on the market to all consumers there is one simultaneous disadvantage to all of these options. They can be costly, inefficient and require constant maintenance.
A heat pump for a swimming pool is an air source heat pump specifically designed to meet the requirements of heating your pool.
They are powered by electricity, but consume far less than their equivalent fossil fuel options, this efficiency is measured in COP,.
What is COP? The coefficient of performance or C.O.P. is the ratio of heat output to energy input, a higher C.O.P. equates to lower running costs.
Inverter heat pumps have variable speed compressors allowing them to achieve higher C.O.P.s than fixed speed heat pumps. For example, at an ambient air and water temperature of 26°C and a C.O.P. of 13, then for every 1KW of energy consumed by the heat pump 13kW of heat would be output to your pool.
Why is a heat pump a better investment to heat my swimming pool compared to the alternative methods?
A swimming pool heat pump is foremost a much more cost efficient design to meet your needs.
For every 1Kw the swimming pool heat pump uses, up to 13Kw of heat will be returned to the swimming pool. This alone makes the swimming pool air source heat pump up to 80% more effective than than other methods to heat your swimming pool than those that are currently on the market.
How does a swimming pool heat pump work?
The simple diagram below shows the sequence that a swimming pool heat pump performs on each cycle.
Step One: The large fan on the heat pump draws in outside air across the surface of the evaporator.
Step Two: The liquid refrigerant within the evaporator coil absorbs heat from this outside air and the refrigerant ‘boils’ and becomes a gas. Because the liquid refrigerant is colder than the surrounding air it can still absorb heat at zero degrees and below.
Step Three: The warm gas passes through the compressor where it is compressed to form a very hot gas.
Step Four: The ‘heat exchange’ occurs in the condenser as the hot gas gives up heat to the cooler swimming pool water circulating through the coil. The pool water becomes warmer and the hot gas cools down as it flows through the condenser coil.
Step Five: The refrigerant gas returns to its liquid form and after passing through the expansion valve the whole process begins again.
What are the clearance distances required for air in and out?
To ensure the most efficient operation, heat pumps should be located away from walls, fences and dense vegetation to allow proper air flow around the unit, if cooled air is not allowed to escape, the build up of cooler air around the heat pump will reduce its ability to heat.
Horizontal units should be placed at least 300mm from a wall or hedge, allowing 700mm to each side, 500mm clearance above the unit and a minimum clearance of 2500mm in front of the unit to allow the fan to expel cooled air.
Vertical units should be placed at least 800-1000mm from a wall or hedge, allowing 800-1000mm to each side and a minimum of 2000mm clearance above the unit to allow the fan to expel cooled air.
