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 supports pools up to 8m3 so would be too small for this pool, please look at the Sunspring 5kw instead
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 = 8m3 so this 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 OK !
10′ x 30″ Intex above Ground pool = 5.5m3 – Nano Action Reversible OK !
12′ x 36″ Intex above Ground pool = 9.6 m3 – Nano Action Reversible too small
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
Or call us to get some help with these items.
Note: The Nano Action requires a pump/filter with a system flow rate of 2.8m3/hr or more to operate (There is an error on the manufacturer’s specifications chart). Please check that your pump/filter is adequate before purchasing.

Installation is very easy and straightforward.
The Nano Action Reversible is connected to your existing pool pipework
It uses the existing pool circulation pump to pump the pool water through it.
Please see the user manual below for more information on how to install your Nano Action Reversible heat pump
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 only uses 0.6kw of electricity to produce 3kw of pool heat.
If you compare this with an electric pool heater, a 3kw electric pool heater would use 3kw of electricity
The Nano Action Reversible therefore is only less than 1/4 the running cost of an electric pool heater – saving you money!
10. Pool Hose
You may need to purchase an additional length of pool hose to connect from your heat pump to the pool
We sell both 1.5″ and 1.25″ pool hose
