This job was a gravity hot water to pumped hot water conversion. What was there was a coal boiler with a conversion burner in it. The job was made somewhat difficult by the presence of a sanitary soil stack on the right side of the wall the boiler was to be mounted to, and a waterheater sitting inches off the wall that we were going to have to pipe around. The house is rental property so it was a budget job. We were actually surprised the homeowner wanted to spend the extra money on a modulating boiler instead of the cast iron ones most landlords want to put in. Its actually a smart move on his part. But being on a budget we couldn't move the waterheater to the corner which would have made a nicer ''canvas'' of the wall. This is a Trinity boiler.
