A question we often get asked is “Can you heat a swimpond?”
The simple answer is yes, however, there are many factors to consider before being able to heat it.
Traditional swimming pools are often heated, especially in the UK where the air temperature is much lower than other countries around the world. When people are drawn to the idea of a natural pool, a swimpond, they want to be able to heat it just as you would with a traditional pool.
Can you heat one?
In reality, it may not be financially viable. Swimming ponds require a significant amount of energy to keep warm due to being a natural alternative to the typical swimming pool.
Types of pool heaters
Pool heaters look a bit like boilers and can run off oil, electricity or gas. Some modern systems will use air-source heat pumps to extract energy from the air.
One of the problems with heating a pool is that the pool will lose heat just as soon as it gets up to the required temperature (usually 26–30°C).
- A super energy- efficient system (perhaps to linked to a ground-source heat pump) with a solar cover. You can invest in a solar and debris blanket, which covers the pool to minimise heat losses.
- A clever option is to invest in some form of renewables setup, which runs through a heat exchanger to heat the water. Using a solar thermal array means the pool will be heated well on the sunny days when you really want to use the pool.
- Another option is to use biomass. For these more complex solutions you’ll need specialist advice, but the significant investment is usually well worth it.
Most of our customers opt for an air-source heat pump, with typical running costs of just £20 per day in summer, for a 11m x 4m natural pool.
So the answer is, yes it is possible, however, it is much more complicated than you may initially think!
