Hot Water Cylinders
Whether you are upgrading or have a new installation requirement - talk to us for expert advice in selecting the right system.
The Aquafire heat pump water heater is a split system which is designed to work with a solar-ready or heat pump-ready storage cylinder. These hot water cylinders are usually situated indoors, and the heat pump water heater is designed to go outside, as close as possible to the cylinder, but it can be up to 15 metres away.
We recommend and supply the HJ Cooper range of stainless hot water cylinders, as they are well suited to operate with our heat pump water heaters and come with a 20-year warranty. There are a number of other indoor and outdoor cylinders available which are also suitable.
The hot water cylinders pictured below come in 180, 250 and 300 litre sizes to suit any household. Please discuss with one of our team which size would best suit your needs.
