Hi, I wish to replace the domestic hotwater service from our boiler, with an electric water heater. Please give steps to do so, and what do I do about the part of boiler that now provides domestic hot water, disconnect? and or drain water from that part of boiler? Thank you, Adam Kadmon

Hi Adam.

Many of these systems are designed and installed by different people.
It would be just about impossible to give you a accurate answer to your question.
You need to have someone On Site to see the plumbing/piping for your install to be able to tell you exactly what you need to do for a electric water heater change over. All else is guess work and when you are messing with a boiler guessing is not something you should do.
