I'm getting a condensing boiler for my house (Monitor MZ25C), and am
considering replacing my gas water heater with an indirect heater
feeding off the boiler. I was quoted $1900 for a 40-gallon tank
(Buderus ST-150) plus installation, and live in Minnesota.
Does this sound right? It's much costlier then I expected. And
assuming this is the going rate for these things, is it a reasonable
purchase? There's supposed to last a very long time and be very
A final point is that here in Minnesota, single-walled boilers are not
allowed by code, (except for some reason Buderus was just now allowed),
which limits choices. And supposedly, double-walled boilers have
trouble keeping up with the Monitor's output, which makes it cycle
several times while heating up the tank.
Thanks for any feedback.
