Torrent Multi Fuel Store HP

Rather than operating with a conventional carbon fuel boiler as the main energy source this appliance has been designed to operate with an air or ground source heat pump. However it still provides mains pressure hot water from an open vented thermal store and enjoys all the other benefits outlined previously for the other Torrent MultiFuelStore appliances.

The main difference when using a heat pump compared to a conventional boiler is the lower temperatures generated by the heat pump. This causes problems in conventional storage/unvented cylinders with low storage temperatures. This can lead to health problems such as Legionella and unacceptable hot water delivery temperatures, which are not helped by the further heat losses that occur due to the need for a primary heat exchanger/coil.
