CUSTOMER TESTIMONIALS
Don’t just take our word for it.
“This is a fantastic piece of kit. The electrician who fitted mine was very impressed with the build quality, documentation, ease of installation and setup. It was up and running in no time. The first full day of running saw it divert 5.6kWh into my hot water tank and the total recovery for the first week has been 20kWh (and I have a battery system so I’m already utilising most of the PV anyway).”
Rock-solid product — G. Hex
“If you have an east-facing solar array (like mine) then this device is a godsend. All that otherwise excess solar power generated early in the morning now converts into a tank full of hot water. In my case, I spend a lot of time in the same room as the IMMERSUN and the fan noise is a reassuring reminder of the bucketloads of solar power I’m generating!”
Love this product — Tim R.
“Only one word to describe it really – brilliant. Last year we tried to put immersion heaters on when the sun shone ourselves. This worked to a certain extent but to have them being heated at a lower wattage up to thermostat point throughout the day is so cost-effective and hassle-free. The app is easy to understand and knowing we are being paid to heat our water and whilst also saving on electric/oil costs gives you a great feeling.”
