'The Immersun unit at the Crossway Passivhaus has clocked up 2,689kWh over 326 days. Looks like we might break 3mW when we meet the year mark which is fantastic ! Let's do the maths; Good Energy's Economy 7 day rate (the one relevant to us) is 16.63p/kWh so that would have cost £447 (not that we'd have used daytime grid electricity to heat our heat store). It's reduced our winter wood pellet consumption by approximately 500kg which equates to about £120 saving in wood pellets i.e. 1/3 of our usual annual pellet consumption. Genius - keep up the great work guys. Hope you enjoy the stats!' -

'I'm absolutely delighted with the Immersun, it is the ideal partner to our solar panels to help us use the spare electricity generated. We have piping hot water in the evening, saving our oil boiler the job of heating it!' - Julian at the garden impressionists

'We've had 365kWh of free hot water from ours since it was installed about a year ago. During last summer, we only had the boiler on 5 times in three months. Saved us a packet. ' - Graham Tapper

'Without the ImmerSUN, Good Energy's Economy 7 day rate would have cost £447, and it's reduced our winter wood pellet consumption by about £120. Genius - keep up the great work guys.' - ‘Richard Hawkes at the Crossway Passivhaus’

'I fitted my immerSUN recently and not only is it very easy to wire, with the excellent instructions walking me through the process having converted the immersion heater supply to a dedicated supply, it was simple to set up as well. ' - ‘Noel Fay’ – an Immersun Man
