My company installs 3-4 Ultra's a year. They are a very reliable unit, and because of the modulation rate, they are very efficient.

I agree with the above post about investigating a domestic hot water system at the same time. It is about 1500 more, but will replace your existing water heater with an approx 90% boiler heat source. Go with the larger tank, as it puts less strain on the boiler.

Costwise, any boiler install will start at 7k and go up from there. The boilers themselves go for 3k+, depending on btu value.

edit-- your existing 15yr old boiler runs no risk of leaking, the cast exchanger can go for 30-40yrs easy.

Absolutely. I have an electric HWH right now, and while I don't run out of hot water, we all know they're inefficient.

To be frank, the W-M 68 Series is older technology, but it's damned reliable. It just keeps cranking out heat ...

I was curious if anyone installs used boilers. I don't even care about making any money on the cost of the boiler... Since I have a working boiler & HWH that are going to be taken out of service, I was wondering if there was a way to get them to a family that could use them - someone that might be cash-strapped and has a broken boiler, something of that nature.

I'll ask my contractor when I talk to him about this whole thing ... I've got to give him a call tomorrow anyway.

Thanks again - this is some good news!
