Caution - Heating Engineers

Depending on the water quality and quantity, in particular in the case of mixed installations and plastic pipes, mineral deposits (rust sludge, lime) may form impairing the proper functioning of the heating installation. A cause of this is the water hardness as well as oxygen dissolved in the filling water as well as additional oxygen from the air which may penetrate via valves, fittings and plastic pipes (oxygen diffusion). As a preventive measure it is recommended that a physical water conditioner such as ELYSATOR be used.
