Yes, it's a one man system and I would like to upgrade it to two but I am also interested in hot water so need to consider that as well. What did you do for hot?

This fogwash thing seems okay. So either follow the install on that or nathaneals advice.

The install that roy showed was good.The basic one man is tank pump heater. Roy has two men off one pump.

I do it differently for two men, and have a back to tank feed.
