Awesome so far
My 30 yr old boiler and water heater gobbled gas and were on their last legs. I yanked them and replaced both with this. An hvac friend coached me along with a couple decisions and choices over the phone. Youtube too. I tapped in to the existing zone sends and returns. Since I installed I had no choice but to learn everything about it which usually doesn't happen. So far I love it and I am sure the utility will be much more lovable as well.

love it.
Fantastic boiler for the price, super easy to install and convert to propane. Loved the air purge feature and the built in air vent on the integral pump. havent had any issues with it and its been running all winter.
