What is the best time of day to use my Eccotherm??
Because it's a heat pump Eccotherm will be more efficient when the day is hot. Unlike solar however, it will still produce all your hot water in the absence of sunshine. Because it relies on the heat in the air it will be more efficient when the air temperature is higher. Approximately 30% greater efficiency can be expected when running at mid-day compared to midnight. Units are set up with an internal clock to ensure operation takes place when outdoor temperatures are high..
Does Eccotherm need sun to make it work?
Eccotherm is an air source heat pump which relies on the heat energy contained in the surrounding air. It works independently of the sun - day or night with no booster element.
Will it work in bad weather?
Eccotherm works in all weather conditions - rain, hail or sun. Peak efficiencies will occur on sunny humid days.
How long does it take to heat my tank?
