I JUST put in a 10 plate HX for DHW. The more I read, the more I think I should have gone 20. Have not had a fire yet so I cannot say if my decision was good or bad. Anyone one up for some pros and cons of the 10 plate?
Senario: put in to at least assist HWH. Going against rule of thumb, mine is after the blower and before the electric water heater bumping up the intake water temp and using the tank as tempering. I hope to make enough hot water that the elements don't turn on, but we will see. Hence my seconf thoughts on the 10 plate. I could replace it, but really don't want to throw away $100 for the 10 plate already installed.
Help a sophmore burner and rookie DHW out.
