5. What size heat pump do I require for my pool?
How to Calculate Your pool Water Volume:
You can easily calculate the water volume in your pool as follows: –
To calculate the volume of a round pool, you can use the formula
Pool Volume = 3.14 x radius x radius x depth
- Measure the diameter of the pool in metres
- Half the diameter to give the radius of the pool
- Multiply 3.14 x radius x radius x pool depth
A 12′ (3.66 m) diameter round above ground pool with a depth of 0.8m
Diameter = 12′ x 0.305 = 3.66m
Radius = 3.66 / 2 = 1.83m
Volume = 3.14 x 1.83 x 1.83 x 0.8m = 8.4 m3
The Nano Action Reversible 5kw supports pools up to 10m3 so would be ideal for this pool!
Pool volume = length x width x depth
6m x 4m pool, 0.8 m deep = 6 x 4 x 0.8 = 19.2 m3
Maximum for Nano Action Reversible 5kw = 10m3 so this pool would be too large – look at our SunSpring heat pumps
Note that a solar cover must always be used when heating the pool and the cover must be kept on the pool whenever it is not in use.
Typical Pool Sizes and Volumes
8′ x 30″ Intex above Ground pool = 3.6 m3 – Nano Action Reversible 4kw OK !
10′ x 30″ Intex above Ground pool = 5.5m3 – Nano Action Reversible 4kw OK !
12′ x 36″ Intex above Ground pool = 9.6 m3 – Nano Action Reversible 5kw OK!
6. Additional Fittings
The Nano Action comes with two screw on hosetails that accept both 32mm (1.25″) and 38mm (1.5″) standard pool hose
You may need some of our fittings so that you can add this heat pump to your pool, so please take a look at our Hose pipe and Fittings

Installation is very easy and straightforward.

Using the Nano Action Reversible heat pump to heat your pool rather than an electric heater will save you money on running costs
The Nano Action Reversible 4kw only uses 0.69kw of electricity to produce 3kw of pool heat.

The Nano Action Reversible therefore is only less than 1/4 the running cost of an electric pool heater – saving you money!
