I own a 165 old stone house and my sons house is about 65 years old and we
both have hot water heating systems. Like everyone else we are looking for
any new technological advances that would help us improve the efficiency of
our heating systems. I have a mid efficiency Viesmamn boiler thats about
15 years old and my sons boiler is about 30 years old.

Any info on how to improve the efficiency of our systems would be much
appreciated.

Thanks in advance

I've worked on a lot of these systems, the best way to increase
efficiency is probably to install a set-back control to tune the
temperature of the circulating water to the outdoor temperature and to
perhaps install a flue damper to help control off-cycle heat losses.
It wont't be cheap, but I think you would get at least a two year
payback and after that the gains are free. This all depends on
factors that I can't see from here, but I think it might work for you.
