I run with my wife a canine hydrotherapy unit in the South West of England and I need some advice on heating our pool.
We have an above ground indoor pool 6m by 3m, depth of 1m and maintained at around 29 dec C all year round. We have been heating the pool with an oil fired boiler but have been considering adding inline an air source heat pump to save money.
I have some concern about the effectiveness of the heat pump as the air temperature drops.
Any suggestions or advice would be greatfully received.
