SAV Danfoss Direct Substations

Ultra-compact SAV Danfoss Direct Substations supply instant hot water in individual dwellings served by central plant. It’s a safe, simple, cost-effective solution that’s engineered for high operational reliability.

Creating hot water only on demand (just like a combi) maximizes the energy saving potential of a central boiler and modern multiple heat source technology. Low return temperatures draw the maximum efficiency from condensing boilers, heat pumps and solar panels.

A single 53 kW Module can produce 19 litres of hot water per minute. Central plant and pipework can be sized using pre-calculated diversity factors.
