Water quality

The indirect heating of the water for consumption is an advantage, which makes Danfoss DWH suitable in areas with high calcium levels
in the water. In installations where the water comes from a well the water should be checked to ensure that it cannot cause damage to
the hot water installation.
• Stainless steel tanks and pipes should not be exposed to water with high chloride levels.
