My current boiler is a vaillant turbomax 824 which I presume is a 24kw output.
Its getting quite old now so considering having it replaced with a similar current vaillant model.
Since the boiler was installed, two additional small radiators have been added.
I measured all the rads in the house and got an approximate output for each one and totalling this up it came to around 35kw.
Most of the rads are controlled with a Honeywell Evohome zoned system, so it is unlikely that all rads will be open at the same time, and the system heats the house satisfactorily.
If I go for a new boiler, should I upgrade to something higher than 24kw or would I be just wasting money?
