Utica boilers are nicely built units. I like the already installed hydrolevel control switch. The units are easy to install and seem to be built with integrity

Yes I would most definitely recommend using this product. I bought my house in 2000 and it had a Utica boiler in the house, fast forward until last week when I finally had to install a new boiler AFTER 40 years of having the same boiler. So for a product that is supposed to last 15-20 years last 40 years I would say they make an exceptional product.

I was surprised and impressed that it took this long for my boiler to be replaced.

Yes I’d recommend your products, I replaced a 45 year old Utica boiler, It was still working, just want to get an up to date model. The new one is more efficient and has a smaller foot print.
