Harlequin HeatStream Electric Plus 150L Indirect Mains Hot Water System

Product Overview

The HeatStream 150 Electric PLUS is an ideal solution for meeting the daily hot water needs of a standard-sized household or apartment. It is tailored for modern living spaces where traditional overfill connections to the outside or an internal waste pipe might not be possible

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 can simply run the overfill to an external pipe or to a low-temperature waste pipe internally within the property. Alternatively, the HeatStream Electric PLUS Internal Overfill models require no external overfill connection at all.

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*.
  (*It requires an overfill connection or overfill kit)
• 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
• Small 520 x 520 mm square footprint, making it perfect for today’s smaller airing cupboards in new build homes, and an ideal replacement for many thermal stores installed in older properties.
• Stainless steel corrugated coils with large surface area provide very fast heat transfer.
