Harlequin HeatStream Electric 150L Direct Mains Hot Water System Internal Overflow

When the Harlequin HeatStream is installed, it is filled with water using the filling loop provided. This static body of water is then heated using the built-in immersion heaters (and or coil on the Electric PLUS). When a hot water tap is opened the cold mains are passed through

a 22-mm corrugated stainless steel coil inside the HeatStream. Heat is transferred from the static hot water to the incoming cold

water inside the coil and exits through the provided mixer valve as temperature-controlled mains pressurised hot water.
