Welcome! Here are some tips for using this forum.
I have a customer looking to convert to gas. They currently have a monster oil boiler and a bock 32e direct fired water heater. Due to some financial constraints (and the fact that the HWH is only a couple years old) they would like to go ahead with the boiler now, add HW later.
Here is the Question... can i tee the gas boiler to the hwh flue pipe or do i have to open up a new hole in the chimney? I know that some people say the safety controls on the boiler and water heater are acceptable as safety shut offs, but i think i should add some type of spill switch because all they do is flame prove... am i right?
Thanks for any help on this subject.
