Combined tank Galmet SG(K) Complete 250/135 for heat pumps - DHW/buffer tank
Combination tank for Complete heat pumps is a complete solution that combines a hot water exchanger and a hot water buffer in one unit. Compact design saves space and is therefore ideal for buildings with air heat pumps.
Complete Tank is a solution in which two separate tanks have been tuned together - an enamelled domestic hot water tank type 250 l and a storage tank for central heating system 135 l. Domestic hot water tank has been placed in the upper part of unit and storage tank in the lower part. One of advantages of this tank is possibility of functioning independently of two heating circuits, i.e. preparation of d.h.w. does not depend on boiler water temperature. Two tanks located in 1 device operate independently and supply two systems: heating of d.h.w. and heating/cooling of building.
Twin tanks are ideal for use with air heat pumps such as Airmax2. Complete 250/135 has a capacity ideally suited to heat pumps of approx. 6kW - 10kW.
Complete tank, thanks to a thick insulation layer of 70mm of polyurethane foam, ensures long water temperature maintenance and low operating costs. Ceramic enamel EXTRA GLASS, creates a smooth and durable protective barrier inside the heat exchangers, preventing corrosive effects.
Additional protection of hot water tank is DIELECTRIC PROTECTION protection of tank connections.
