Hi Houzz!!! Looking to replace an old boiler w/ one of the two above. Cost is about the same, but I'm wondering if there are any opinions on Peerless vs Burnham in general, or comparing these two units in particular. AFUE seems to be within .5% for both, so really more curious about reliability. I know every home is different etc, but just generally is one of these more dependable or well known? Price and install for either unit is almost a match. THANK YOU!!!
