Sunamp Heat Batteries

Cascades of hot water from a heat pump.

The space-saving Sunamp UniQ HW +iLTHP heat batteries work with low temperature heat pumps to provide hot water for all your needs.

With a signal from the heat pump these heat batteries can be boosted electrically if required with an internal element also acting as a backup so that they never let you down.

Easy to fit, the Sunamp UniQ HW +iLTHP heat batteries provide a better alternative to outdated indirect cylinders and thermal stores for compatible heat pumps.

Available in four sizes which can also be combined, they are the right solution to perfectly match the exact hot water requirements of your property.
