Caravan hot water systems are one of the more problematic appliances installed in your van. Maintenance type water heaters require the regular replacement of the anode, so you should always carry a spare. But did you know that when you replace the anode, you should flush the tank at the same time? Also, there are a number of different types of anode which can give better performance for different types of conditions.
Because the caravan hot water systems are under such high pressure, they are subject to leaks from the tank, and also through the plumbing inlet and outlet fittings, as well as the over pressure valves. A leaking hot water system in your caravan can cause a huge amount of damage if left unchecked. From wetting your gear to completely destroying the floor and furniture.
