This product is the Storm 18 KW /3 Phase Electric Combi Boiler This boiler was bought by a man who installed underfloor heating, unfortunately he didn't come every day and he installed it for me for 8 months until the electrician said that the purchased boiler was too powerful for my very small apartment of 30 m2. The man ran away and left me with everything and now I want to find a willing person who will buy this very good boiler. The boiler was not installed at all, as can be seen from the side walls of the boiler(please see photos) Please feel free to ask any questions, I will be happy to answer them. The boiler is on post code: SW15
