Air energy, low temperature heat pump water heater, ground heating + hot water + air conditioning triple for one machine, how to use it in the end? Is there any good publicity? If it's warm
Please choose a good brand, as for which good, depends on what angle you choose, if only the air - energy heat pump water heater,
I don't know where you are. What's the temperature in winter? If it is below zero, the effect of the so-called air energy is greatly reduced. Purely using air heating is objectively unrealistic. The use of electricity as an auxiliary energy, the use of the cost will be high.
Air energy heat pump water heater heating + hot water + air conditioning triple supply, of course, is better, this is more economical. I can't tell you a word here. You'd better go to some experience tubes to have a look. Only your own feelings, is the best way to convince you, the future may be everyone will use. I still compare this to the people, but I can't make it clear at once
