This range is ideal for above ground or in-ground pools that you want to use for an extended season.

The Thermotec Eco Fun deliver greatly reduced running costs with COPs of up to 5.98. This means that for every 1kw of electricity used by the heat pump, 5.98kw of heat is delivered to the pool. This delivers reduced running costs compared with electric heaters on the market.

3a. What size heat pump do I require for my pool?

The sizing guide for an in-ground covered pool is:-

Model Kw Above Ground Pools

Max Pool Volume

In ground Pools

Max Pool Volume

In Ground Pools
Absolute Max Pool Volume
Thermotec Eco Fun Horizontal 5kw 12m3 25m3 35m3
Thermotec Eco Fun Horizontal 8.5kw 25m3
Thermotec Eco Fun Horizontal 11.5kw 35m3
Thermotec Eco Fun Horizontal 13.5kw 45m3
Thermotec Eco Fun Horizontal 15kw 50m3


Please note if you have an above ground pool, please increase the size of the heat pump as there will be more heat loss from the sides of the pool than an in-ground pool.

4. COP And Performance

The Thermotec Eco Fun heat pumps can work well with outside air temperatures as low as -7c

Even as the outside air temperature falls, the Thermotec Eco Fun will still perform well, delivering heat to your pool.

The COP (Coefficient of Performance) is the ratio of the amount of heat (in kw) that the heat pump delivers to your pool compared to the electricity that the heat pump uses (in kw)
