Standard 12v Isotherm boiler Kit
Our intelligent controller constantly monitors the state of your batteries. If they are at least 80% charged, the electricity from your solar panels is in effect diverted to your water heater if the temperature is under 43°C. It cuts off at 52°C. Electricty consumption is modest because most of the time all you are doing is topping up, not taking the water from cold to hot! The fridge can stay on to keep the beers cold!
The existing mains electricity heating element is replaced by our 300w 12v water heating element supplied, and you get all the various items that you need to get it installed excluding the fuse/switch and cabling.
