Hi everyone. I have recently purchased a home and am in the process of planning renovations. The house is old and the current geyser will have to go ( its a very old geyser). I am looking at getting an IHP geyser for the property. Has anyone installed one of the 200litre units from power4less? If so how are you finding it in terms of consumption and efficiency? We are a family of 4. I am intending on going with a solar and battery back up system and hoping that the IHP geyser can also be powered by the system.
