What are the Types of Caravan Water Heaters?

Any sort of water heater appliance for caravans run can run on a few things. They are generally either gas or electric, but can also run on diesel or a mixture of two or more of those things. They can also run on solar energy if you can get enough panels and charge from the sun. However, there are only three main caravan water heater types. They are Boiler, Therme, or a Combi heater. Let’s take a look at each individual option below. 

Therme Caravan Water Heater

A Therme heater is actually the smallest caravan water heater model type. They usually have a capacity of approximately 5 liters, which is integrated into your caravan’s pre-existing warm air system to heat water for your shower or kitchen taps. This is the cheapest and most cost-effective way to get hot water for your caravan holiday.

Combi Caravan Water Heaters

If you need maximum power and water capacity, a Combi water heater is your ultimate choice. It can hold up to 14 liters of water or more in some cases, and uses electricity only to heat water. Not only does it make hot water, but it also has the ability to keep the water hot for a considerable amount of time. If you have an unlimited budget or are willing to splash the cash, we highly recommend that you buy Combi caravan water heaters. They are the most expensive option, but that’s for a reason.

Boiler Water Heater

Boilers heaters are very effective and can be powered either by electricity or gas. Boilers usually have a capacity of up to 10 litres, which is double the size of Therme models. They use an additional heating rod to heat the water without draining your power supply too much. These are definitely a convenient option, offering great value for money with ecological power usage.




Why Do I Need Caravan Water Heaters?

Can you last any amount of time caravanning on the road without washing your hands, washing pots, or even showering without hot water? Me too, it’s an absolute nightmare. Caravanning is great, but you do want more luxuries than a Siberian salt miner. You’re on holiday, remember. When you travel in a caravan, you really do appreciate the simple things in life like access to hot water. And by that definition, having a caravan water heater should be an essential, not a luxury.

In order to perform the ‘hook up’, you’ll need to buy an electrical cable to connect it to the mains supply. A cable that can receive a normal A/C electrical current is essential in this instance. Most campsites have these electrical access points, but we would suggest that you check with the campsite owners beforehand.
