The furnace is working all day but the house just does not get warm enough.
This page is a guide to help you
understand, why your home is not warm
enough. Many people think a new, or
larger boiler will solve the problem,
but in most cases it will not. I have
had people ask me to install a new
boiler, and after it is installed, they
complain that it is not putting out any
more heat then the old one. If they told
me the problem was not enough heat I
would have explained that, most of the
time it has nothing to do with the age
of the boiler.
