Our church as a hot water heating system, fed by a large gas-powered boiler. The boiler is old and needs much repair. It is a two-zone system; one zone for the church sanctuary (upstairs) and one zone for the church hall, kitchen and offices (downstairs). We are thinking of replacing the boiler instead of repairing the existing one.

My questions are:

1 - would it be better (more cost effective and more energy efficient) to install 2 smaller boilers - one for each zone - rather than 1 larger boiler?

2 - what is the approximate cost of replacement boilers? (I understand that labour is an additional cost.)

3 - For our use - Sundays and occasional week days - would a medium efficiency boiler(s) be a better choice than a high efficiency unit(s)?

The current system was installed in the 60's and is 650 MBH. I am sure new boilers are much more efficient. Because we are a church, the building is only heated to normal comfort levels on Sundays and one or two days a week as we rent the basement hall. When the building is not occupied, we turn the temperature down to +/- 12 degrees C.

Defiantly go with 2 boiler system that way if 1 fails you always have heat.

It all depends on the application of the site. 2 boilers sounds right but again it would have to examined and expected before making decision
