  • Description

    An ErP 'B' rated thermal store for flats, apartments & electrically heated properties

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