Going to add new rad to system.......

[gregoski]

Hi Guys,
Sorry if there is any similar thread but can't find myself at the moment, so decide to ask out loud.
Have a gas boiler Potterton Promax Combi28HE A Plus (output 28kW) I need to add one more radiator to the system. I have already 7 rads in the house. upstairs 4 x single panels and downstairs 3 x double panel ones. Semi-detached house(pre-war built).
The reason for this improvement is that the spare toilet is constantly cold and that leads to build of condensation and mould started to appear on walls, as outer walls leads to back garden. Spare toilet with little corridor leading to back garden is connected to kitchen but there is only small double panel radiator. So thought that add up small rad will improve air circulation in spare toilet and will help to prevent damp and mould.
Looked for some manuals or tech guides for that type of boiler on google but only been lucky to gather some info relating to other manufacturers products of same output stating that it can be up to 14 rads.
Any suggestion guys will be appreciated.

If it's 28kw your boiler will be big enough. Just make sure that if you take it off the flow and return from the other radiator is big enough to cope. Piggy backing can cause issues.
