Rensus Ltd are recognised installers of the immerSUN device.  This clever piece of equipment diverts all of your excess solar pv energy produced by the solar system to your hot water cylinder's immersion heater. 



Savings can be significant, especially if you use oil, LPG or electric elements to heat your domestic hot water, and payback can be as low as 2 years. 

​

The immerSUN device is quick and easy to install. You can get the full benefit of your solar pv system by using the excess energy to heat your hot water, towel rail, or storage heater.
