Model h100id banging noise when turned on shuts off
VERY low water flow!
Or... No water flow.
This heater as all heaters do, need to have sufficient water flow thru them, or else they Bang like this.
This then creates a problem, for future banging - due to lime up!
The minimal water flow gets so Overheated, that it turns to steam! The steam knocks and pushes the heater around, then the Minerals will precipitate out of the water and forcefully attach to the inside walls of the heat exchanger! Which will then drastically reduce the inner diameter of the exchanger making a much smaller passageway for water to travel thru! This is a major problem to remain this way. It will then need to be dismantled and de-limed to increase the holes once more, and allow a proper water flow.
