GALMET MAXI PLUS is a bivalent exchanger which ensures maximum use of heat pump power and enables heating up to 500 litres of domestic water. An additional solar coil has been placed in the lower part of tank, which gradually heats up water in the whole tank.
GALMET MAXI PLUS is equipped with thick insulation, thanks to which it is very efficient, provides negligible heat loss and low operating costs, which increases the comfort of use.
The top anode should be replaced regularly to protect tank and extend its life. Active titanium anodes can also be used, which are maintenance-free and require no maintenance. However, thanks to the use of EXTRA GLASS ceramic enamel we can use our tank for a long time and hygienically.
Connections located at back allow for comfortable use. Lightweight external casing made of skay makes it easy to transport exchanger to place of investment. Standard colour of casing is grey, but one of 4 additional colours can be ordered free of charge: red, blue, green, white.
