Before you do so you might also want to look at our frequently asked boiler questions.
Sorry comments are closed at the moment.


You state the size but not the weight. Do you know what is the weight of this boiler and will it fit on a wall?
These type of boilers are often wall hung and the small dimensions mean that they are not unsightly.
The manufacturers guide says these weigh 22.6 kg, not a large boiler so the installer should be happy to fit this one.
The gas supply to my boiler is only via 15mm pipes. Do any boilers run on this supply - preferably a system boiler?
No condensing boilers run on this supply, unfortunately all condensing boilers have to have a 22mm supply, whether they are system or combi style.
