There are two types of water heater used in motorhomes and caravans, stored hot water and instantaneous hot water.
Instantaneous water heaters are rare nowadays due to changes in gas regulations and only appear in older vehicles.
However they can be repaired as many of the parts are still available especially on Vaillant heaters, but also if an instantaneous heater is already fitted it can be replaced as long as up to date regulations are followed.
Stored water systems are far and away the most common heaters used in motorhomes and caravans.
Truma water heaters and combi boilers are most commonly seen in new vehicles along with Alde systems which are becoming more popular.
On older vehicles the Carver Cascade was a popular choice and parts for them are still available from the manufacturer, other than replacement tanks.
If a Carver Cascade heater is beyond repair there are a number of alternatives which can be fitted in place of the original.
I can often diagnose a problem with a heater without seeing it, if you have the make and model and can explain what it is doing.
If you have a problem with your water heater please give me a call or drop me an email.
