How to Calculate Your pool Water Volume
You can easily calculate the water volume in your pool as follows:-
Round Pools
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
Example
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 SunSpring 5kw supports pools up to 12m3 so would be OK for this pool, as we always allow a 20% difference in the pool volume in the pool and what volume the heat pump can cope with.
We always recommend going up in size when choosing a heat pump (where possible) as the results will be far more satisfactory, especially if you are located anywhere north of our location in Essex. All our sizing is based on the South of the UK outdoor air temperatures and any difference to this equation will make a huge difference to performance of the heat pump, and the results that you feel in your pool.
Rectangular Pools
Pool volume = length x width x depth
Example
6m x 4m pool, 0.8 m deep = 6 x 4 x 0.8 = 19.2 m3
