Hello, we are updating our wood burner and would like to fit a wetback, can we fit one to this type of mains pressure cylinder or would we need a new cylinder as well, is mains pressure OK for a wet back installation or do we need to drop to low pressure? Thank you for any advise.
Mains pressure Rheem 322-180-15 around 6 yrs old.
