domestic hot water from boiler
apologies if this has been covered here. I tried searching but may have been using incorrect terminology. Currently we have a coil inside our steam boiler for domestic hot water. It worked well enough in the winter when we were running our steam heat all the time, but now we have added some air-source heat pumps and are not running the steam heat much. We would like to add an indirect water heater. I've seen on-line that one can get a coil installed in a a water tank that uses hot water from the boiler and that this would be much more efficient than firing the boiler every time we needed hot water. I've had 3 HVAC people not that interested and even telling me it could not be done. Where do I find a contractor in the Metrowest Boston area who knows steam boilers and can tell me if I can do this or not? Thanks!
