Water heater GALMET with 2 coils - SGW(S)B 250
Vertical heat exchanger designed for heating of hot water. (domestic hot water) using two energy sources. Solar energy is ecological and provides us with heat all year round and can serve as the main source of heat. An ecological central heating boiler can be used as a second heat source to support solar system in winter. The lower coil is designed to connect the upper solar system to central heating system. Water can also be heated by means of a heater located in inspection opening (accessory).
The big advantage of exchanger is its insulation, which reduces temperature loss to a minimum. Long temperature maintenance significantly reduces costs, saves energy and improves comfort.
Exchanger is protected against corrosion in form of EXTRA GLASS® enamel. This enamel is applied evenly on whole surface in wet technology. Two magnesium anodes used additionally protect exchanger and ensure hygienic use. Magnesium anodes periodically have to be checked and changed, but they can be replaced by an active magnesium anode which does not need to be replaced.
Use of top-class raw materials together with advanced production technology guarantees the highest quality of exchanger. Therefore, warranty period for exchanger is as long as 60 months (details are provided in warranty card).
