Husband and I are planning a new boiler install (seperate thread) but have a question regarding expansion tanks.
right now on our boiler is what looks like a #30 extrol expansion tank. (Its leaking bad).
We need to keep it going until our new boiler is installed.
Does it have to be replaced with the same size or can we use a #15 extrol expansion tank. (Reason being that we can get one for free)
Are they sized to the boiler?
If the answer is no to using the smaller tank, at how many btus is the max for the smaller tank.
