Space saving with the Sunamp UniQ Heat Battery compared to the equivalent hot water cylinder

The Sunamp heat battery works well for hot water and/or a space heating supply. It works with heat pumps, can be charged with cheap rate economy 7 and/or solar photovoltaic electricity and for heating and hot water with combi boilers.

Sunamp UniQ heat batteries are a way of maximising the ROI (Return on Investment) of solar systems, replace space wasting and inefficient hot water cylinders and reduce your carbon foot print by using excess solar produced electricity to charge the battery. You can also charge them using cheap rate overnight electricity (Economy 7 or equivalent).

How it works: The ‘battery’ is made of a simple chemical similar to that found in hand warmers. It is ‘charged’ using electricity. When it ‘discharges’ the heat stored by the battery is used to heat your hot water for washing up, showers and baths. This removes the need for an inefficient, wasteful hot water cylinder. The Sunamp UniQ heat battery provides instantaneous heat for you when you need it.

The image above shows how the system works with a solar photovoltaic system. The excess electricity generated by the solar panels is used to charge the thermal battery. This heat is released to your hot water system when you need it simply by turning on the tap.
