Zodiac Z300 MD5, M7 & MD8 Heat Pumps


Why use a heap pump, isn’t solar more efficient? 
Although a solar heater will receive all its heat energy from the sun this is only truly effective on sunny days and they may struggle to reach temperature on cloudy or unseasonably cold days. This is where a heat pump can have a real advantage as a heat pump will draw heat from the ambient temperature even in cooler weather.

Doesn’t a heat pump use a lot of energy? 
Certainly not. Although a heat pump requires electricity to operate it draws over 80% of its heat energy from the air and it does this even though it may feel cool. Drawing heat from the ambient air temperature and using principles similar to a reverse cycle air conditioner, the Z200 then heats the pool water.
