Sunamp Heat Batteries

View the latest range of Sunamp Heat Batteries at competitive wholesale prices from the UK’s best renewables distributor.

Sunamp’s UniQ Heat Batteries are designed to efficiently store heat for domestic hot water systems. Their super-compact Heat Battery technology offers a uniquely clean, safe, compact and very low maintenance thermal energy storage solution.

Using the non-toxic phase change material (PCM), sodium acetate,  they can be charged with a variety of energy sources: 

  • electricity from the grid (e.g. at off-peak rates)  
  • air source heat pumps, 
  • solar PV systems
  • ground source heat pumps
They can be retrofitted to existing hot water systems,  or specified for use in new build projects. Sunamp Heat Batteries can substitute a standard hot water tank in a fraction of the space.

With a lifespan of up to 50 years, and very little maintenance required, they are proving popular with housing associations too: They completely negate the risk of Legionella and the cleaning requirements of typical hot water systems, on top of the space-saving for occupants.  

The UniQ batteries are available in 7 different models with 3kWh, 6kWh, 9kWh and 12kWh capacities. For domestic hot water we recommend the 6kWh battery for 1-2 bed properties; 9kWh battery for 3 bed properties; 12kWh battery for 4 bed properties. 

For space heating, you may need to use several heat batteries in parallel and recommend contacting us for advice for configuring such systems.
