Hawley Boiler Install

This is a water boiler replacement for a house that was still operating on gravity hot water heat. Some years ago, some yoyo took the asbestos off the Mercer boiler, but that left gaps in the heat exchanger big enough to put your fingers in. You could actually see into the flame. The electrician who is the clients regular guy, said he couldn't stand to be in the basement during winter. No dought! He was getting fumigated. Someone actually covered the boiler with wall cavity insulation in a sorry attempt at replicating the asbestos cement. We put in a Munchkin and an Ergomax combination buffer tank and water heater. The original single zone is now three zones. Two high temperature and one radiant floor.
