I have got an old potterton bolier providing DHW/CH via a cylinder and header tanks. The boiler is an old cast iron one and is absolutely fine but at some stage it will need replacing. The obvious thing to do is replace like for like and continue with the system I have got. The other option is to replace with a combination boiler and remove the old cylinder and tanks to create extra space in the bathroom and loft.
I'm prepared to give this a go myself if the sequence of events is logical. What considerations are there in converting from the old system to combi boiler? The pipework will obviously change but not to drastically. The pump is upstairs in bathroom. This will need to be removed as new pump will be in combi downstairs. The cylinder and header tanks will need to be removed and relevent pipework reconnected. Will taps, cistern washers etc need uprating?
And finally if I do go down the combi route, what size/type would be recommended for a 3bed 3reception house currently let out as a 5 bed
1recepion with 1 kitchen and 1 bathroom (with electric shower, which I could convert to thermostatic).Any help gratefully received
