GALMET MAXI is a heat exchanger that ensures the best use of heat pump's power and enables heating up to 1000 litres of domestic water. Thick insulation was used during production process, which makes GALMET MAXI more efficient. It ensures negligible heat loss and low operating costs, which guarantees comfort of use.
The lower anode and regularly replaced upper anode extend its durability and protect inside of tank. To improve performance of tank you can also use active titanium anodes that do not require maintenance and service.
EXTRA GLASS is a ceramic enamel that covers entire interior of tank to ensure long, hygienic use and to adequately protect our tank.Optimized design allows for quick and comfortable installation. Connections have been placed at the back allowing for comfortable use. Lightweight outer casing made of skay makes it easy to transport exchanger to investment site. Standard colour of casing is grey, but you can order one of 4 additional colours: red, blue, green, white.
