Most Liked Positive Review
So far its been great!
Its only been a week or so, but it seems to be great. I love the Economy Adjust mechanism as it is something that I hated was missing from our old boiler. If you are not familiar with the economy adjust, it allows the hot water in the system to circulate first to see if it meets the demand for heat before the boiler fires. Some may dislike all the safety checks involved in a boiler like this but after our old oil boiler back fired 3 times it certainly gives me peace of mind knowing that it will shut itself down if any issue occurs.

Most heat it produced was from my temper
It did not in 10 years work for a year without minimally 1 or two repairs. I purchased this unit at least 2 times over. Now it needs a new gas valve--I do not have the money for this years repair. Even if I do the work myself.

I would buy again.
This was purchased to replace a similar older unit. Installation was pretty easy. This has a more user friendly design. Unit came in slightly damaged. I was able to straighten the bent partsn and Supply House refunded a discount. I appreciate that. Unit works well...not winter yet, but expert it to be fine.

1.5 Years Leaks
I read many things online about the heat exchanger leaking but thought with all these positve review, it wouldn't happen to me. It did. Plus, I have many times smelt gas and my gas sniffer also detects a leak. JUNK!!!

Good purchase, no hassles
The boiler is a good, quality product. Fair price. Shipping was excellent, no damage whatsoever. Delivery Co. had a lift bed and got it to my driveway and I took it from there. Delivery was delayed a couple days for them to schedule. The boiler is excellent except the pressure gauge is defective and reading about 14 at no pressure. Not sure if I should make a claim.
