ThermaFlow 'E' Plate Heat Exchanger Packages


The Thermaflow 'E' range is the latest generation of GMS's highly successful plate heat exchanger packages. The main application of the Thermaflow 'E' is the instantaneous generation of Domestic Hot Water (DHW) using Low Temperature Hot Water (LTHW), with or without a secondary Buffer Tank.

At the heart of the package is the highly effective Thermaflex gasketed Plate Heat Exchanger. Primary water is driven through the heat exchanger by the primary pump. The pump is glandless for low maintenance and powered by the latest high efficiency motors. The motors automatically modulate speed to match the demand, therefore saving energy due to this improved control. For example if there is no demand, the control valve is closed and the pump motors stop completely.

Each primary pump is EUP compliant and A rated for its energy consumption, therefore meeting the requirements of UK Building Regulations as well as the new EUP legislation.

GMS are committed to reducing the impact on the environment of our products and the Thermaflow 'E' range embodies this commitment.
