Harlequin HeatStream Electric Plus 150L Indirect Mains Hot Water System With Internal Overflow Kit

Product Overview

The HeatStream 150 Electric PLUS with Overfill ensures a consistent and ample supply of hot water, efficiently meeting the demands of standard-sized households and apartments. It is also equipped with an overfill system, offering added safety and convenience, particularly in settings where managing excess water is crucial.

It is an open vented thermal store and therefore not subject to part G Building Regulations in the U.K. and the discharge requirements associated with traditional unvented cylinders. It is very well suited to flats and apartments, but equally at home in larger properties.  The HeatStream Electric PLUS Internal Overfill require no external overfill connection at all. Alternatively, the HeatStream Electric PLUS can simply run the overfill to an external pipe or to a low-temperature waste pipe internally within the property.

Once the 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 is passed through a 22mm corrugated stainless steel coil. 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. So simple…

Features and Benefits

• External discharge not required overcoming part G of building regulations in UK.
• ErP B rating for energy efficiency with a heat loss of only of 1.12kWh per day.
• Maximise the benefit of available off-peak electricity tariffs or solar PV.
• Pre heat in 10 mins from boiler
• 14-bar rated primary coil ideal for district heating
• Mains pressurised hot water with No G3 qualification requirement for installation, and no requirement for expansion vessel or T&P relief valve
