Would it be safe to put something (perhaps a a piece of wood?) on top of the water tank of an electric immersion water heater? It is making a lot of noise (not only the splashing water) and I'm sure it's disturbing the neighbours as it's quite loud. It also had gathered a lot of dirt at the top and looked like nobody had cleaned it for many years. So I though covering it would prevent the future dirt from going into the water as well. So is the open-top design necessery for the tank to operate safely or could it be closed up with something? Any advice would be appreciated,
Would need a bit more info. It sounds like you are talking about a split hot/cold water tank commonly used in flats. If this is the case it wouldn't be a problem to cover the top of the tank with possibly a shelf that was removable for maintenance.
Ho, yes that sounds like it, the top department is for cold water, it is about 30cm deep and water flow is regulated by the ball (like in the toilet). I can't really see much of the rest of the tank beacuse it's in a corner and behind a piece of wood. Thanks for your help,
