Replacement Boiler Recommendations?

We are considering replacement of the original A.O. Smith boiler in our upper Lucas Valley "Double A" Eichler, in order to obtain better energy efficiency, to reduce our energy costs, and to enable the use of a programmable thermostat.

We received a quote from Caron Plumbing in San Rafael for the installation of an Allied Engineering 125,000 btu, 84% efficiency boiler for just under $4,500. With a new pump, which was recommended, and a programmable thermostat, the total cost will be just under $5,000.

Has anyone had any experience, either good or bad, with Caron Plumbing, or with this particular Allied Engineering boiler? If so, please e-mail me directly with feedback at

Should we consider other contractors, such as Anderson Radiant Heating in Campbell? Should we consider other boilers (I note that there is a very high efficiency Munchkin 140M boiler rated at 92% efficiency for under $3,000)? If so, please e-mail me directly with feedback at

Any help or insights would be greatly appreciated!

Hi Dick:

You might also check out Jerry Rothfeld Hydronic Heating. He is up near your area and specializes in boiler replacement. Jerry prefers to use atmospheric boilers, which are not quite as energy efficient as the super efficient Euro boilers. His reasoning is that the atmospheric boilers are quieter (no fans) and have no moving parts and thus he never seems to get call backs for repairs, which he likes. He is an advertiser on this site, and his # is 800.478.3060.

You may want to check out some of the other companies who advertise here as well. At least this should get you started.
