Adding radiators query

[GaryinAshby]

I need to add a few radiators to my system for a new extension. My boiler is a Baxi Bermuda inset fire/back boiler. This is 5 years old.

In the house I have:

5 off 6' x 2' 6" radiators (singles).
2 off 2' x 2' 6" radiators (doubles).
1 off 2' x 2' 6" radiator (single).

I am looking to add:

1 off 6' x 2' 6" (single).
2 off 2' x 2' 6" (doubles).
1 off 2' x 2' 6" (single).

I've been informed that the boiler will be fine with this, anyone confirm/deny this?

Depends on the output of your boiler. You need to calculate the total heat output of the radiators - the catalogue should give you this info, and you can also use it to give you a rough guide of the output of the existing rads. If the total output of the rads is less than the max output of the boiler, you'll be fine. If it's more, then it's new boiler time.
