Heating Your Pool or Spa with Electricity
A heat pump is simply an air conditioning system working in reverse.
A heat pump takes in large quantities of air via the fan. The heat contained in the air is absorbed by the refrigeration gases in the radiator. The cold air is expelled from the unit via the fan. This heat is transferred to the heat exchanger. The pool water is pumped through the heat exchanger and collects this heat.
This heated water then returns to the pool.
The main characteristic of the heat pump absorbing heat from the air means that the system has a low electrical input relative to the heat output.
Heat pump output heat at a rate of around 5:1. This factor is called the co-efficient of performance or COP.
This means that a 5Kw heat pump would be generating an equivalent heat output of 25Kw.
Or will it?
Not exactly, as the COP will change depending on the ambient temperature.
The heat pump design, and the ability of the heat exchanger to effectively transfer the heat to the water are extremely important.
Heat pumps, correctly chosen for their intended purpose and used correctly, can be a very economical way to heat the pool.
It is important to decide on how long you want your swimming season. Do you want a small heat pump to take the chill of the water in the spring and autumn, or do you want a heat pump that will keep the pool warm all year?
It is VERY important to choose the correctly sized heat pump for your pool, and the correct specification for the climate in which we live.
The costs to install a heat pump will vary greatly depending on your requirements, pool size and pool location.
Typically the costs start at around $4000 for a basic small pool season extender.
