Electric immersion heater, er, ah, oh of course we had an Ideal boiler under there and it, that's what heated this kitchen actually an Ideal boiler and it heated the water in the winter and also heated the, and in the summer we let that out and had an immersion heater, well being in the electrical trade we had an immersion heater all the time and if we wanted to top up from the boiler we used to just put the immersion heater on for a erm week or so and get hot water and then let it go off in the winter time, you know, but er  we haven't made a great deal of alteration to this place really, we've put a new front door on fairly recently, that was one of the things that er was very ugly, they, the back of the front of the doors to look at, ooh they were ugly doors
