boiler question

rooster

I have an IDEAL classic boiler ff340 and was planning on adding a thirteenth radiator to my conservatory but I am concerned that this will be to many for the boiler. I did ring IDEAL who mentioned 40,000BTU but I don,t know how to find out how much each radiator is set at. any advice from plumbing wizards would be great.

Its also much less of an issue if you have TRV's on the rads since its probable they will not all be open / running at once.

You would need to work on the assumption that all the valves WILL be open as at some time they will be.

Depends on your system. i have 14 rads and 2 of them are only on when the hot water is heating which is 1 hour a day.

The only thing that would happen if all were running is the differential would drop, hardly something worth chnging a boiler for.
