Mixergy Ltd has developed an efficient hot water tank that makes use of a novel inlet diffuser and angled heating element scheme to increase the utilisation of stored water within a domestic hot water tank.

The SME received a statement of verification by NPL as part of the Environmental Technology Verification (ETV) programme for their 'energy technology'.

The Mixergy tank has an inlet arrangement that reduces mixing to increase the amount of hot water that can be recovered from a given preheated tank volume.

NPL were able to verify that the Mixergy tank, with a volume of 75 litres, was able to deliver 120 litres of hot water at the threshold 43 °C compared to 90 litres delivered by a tank built to British Standards.
