In Reply to: should we upgrade to a modulating boiler? posted by Dave on October 02, 2005 at 10:31:26:
The Efficiency+ is a 2 stage firing boiler. So how much more could you gain unless it is way over sized. With a copper fin boiler you should pipe primamry/secondary. Maybe re-piping and getting some boiler controls might be a better use of your money.
