Domestic hot water systems

Product store

Water heaters can be split on three main groups, based on principle of hot water production: water heaters with tank; instantaneous water heaters and freshwater modules.

Water heaters with DHW storage tank are suitable solutions for hospitals, sports arenas, hotels, apartment blocks and similar large buildings. The product range covers storage and charge systems which all combine the demand for high-performance, comfort, hygiene and resource-efficient operation. The systems can be combined with a second or multiple DHW storage tanks for optimum tailoring to on-site conditions, available with ready-to-mount piping.

Instantaneous water heaters provide hot water instantaneously and only as it is needed. Danfoss offers a comprehensive range of products with different control solutions based on principles of flow, thermostatic, flow and thermostatic or electronic controlling.

Fresh water modules provide hot water, based on instantaneous principle from a heat accumulator. The accumulation buffer tank can be supplied by many different energy sources e.g. solar, boilers, district heating or heat pumps.

Instantaneous water heaters

The instantaneous water heaters are suitable for smaller households, as they provide hot water when you need it - you get instant hot water. Compared to storage water heaters they do not generate standby energy losses and can therefore save you money.

Fresh Water Modules

Fresh water modules provide hot water, based on instantaneous principle and only as it is needed from a heat accumulator.
