What is so good about a heat pump?
Heat pumps are closely related to air conditioning units. Instead of taking heat out of the air and discarding it they use the heat to warm up the pool water. The air doesn't have to be all that warm, even at 10 deg C a heat pump will work very well.
Best of all you get more Kilowatts of heat out than you put kilowatts of electricity in. The heat is put into the water by compressing and evaporating gasses. The energy required to run the gas compressor is much less than the energy the gasses transfer to the water so typically for each unit of electricity put in you get 4 units of heat out.
What is so good about the TDM Heat Pump?
Designing a heat pump is all about getting the balance between the gas compressor, the heat exchanger and the evaporator to produce the most heat for the least energy input. But not only that. The performance at low temperatures and the noise produced are just as important. To make a heat pump produce 4 times its input at 30 deg C is easy. To make one produce over 5 times its input at 10 deg C (typical night time temperatures in the UK) and do it quietly takes clever design and a dedication to quality. Add to this a warranty lasting up to 10 years and you can see what makes the TDM stand out from the pack.
With Economy 7 electricity the best time to run a heat pump is at night but it’s cold at night and so you can’t run your heater. Think again! Below are the performance figures for the TDM at 10 deg C, typical night time temperatures. Even at night the M35 can pump 22kw of heat into your pool for about 12p per hour. A direct electric heater in the daytime would cost £2.00 per hour. The biggest Calorex heat pump can't reach these performance figures during a hot day and costs £700 more.
