What is the difference between these Evacuated Tube panels and the Flat Plate Panels?
On a hot and sunny day they both offer good benefits. However, the newer technology of Evacuated Tube Panels has led to much greater efficiency in operation in less perfect conditions. This is most apparent in our changeable climate, where wind or weak sun can prevent the flat plate collectors from providing any useful heat. The Evacuated Tube collectors will continue to work in relatively overcast conditions when the traditional Flat Plate collectors cannot. As such, the Spring and Autumn seasons can offer good amounts of hot water and even in sub-zero conditions on bright Winter’s days, as the solar energy is trapped behind the vacuum, rather like a Thermos flask.
