Caravan Water Heaters & Anodes


Caravan Water Heaters & Anodes

Shop caravan and RV hot water essentials including water heaters, replacement anodes and common service parts. Anodes protect the tank from corrosion, so replacing them on time can extend the life of your hot water system—especially if you travel in areas with harder water.

To choose the right anode, check your heater brand/model and confirm the thread type, length and diameter. If you’re unsure, compare your existing anode measurements or the heater’s part number before ordering.

If your hot water system isn’t performing well, common causes include a worn anode, scale build-up, valve issues, or incorrect fittings. Start by identifying the heater model and doing a quick visual check of the anode and connections.


What does an anode do in a caravan water heater?
An anode is a sacrificial metal rod that attracts corrosion so the tank doesn’t. Over time it wears away, and replacing it helps protect the water heater tank from rust and damage.
It depends on water quality and usage, but a common rule is to inspect it at least yearly and replace it when it’s significantly worn. Hard water can wear anodes faster, so more frequent checks help.
Match the heater brand/model first, then confirm thread type, length and diameter. If you have the old anode, measuring it and comparing to product specs is the quickest way to get the right one.
If the anode is heavily eaten away, thin, or rough and crumbling, it’s due. Poor hot water performance can also be linked to scale or other parts, so checking the anode is a good first step in troubleshooting.
Often yes. Turn off power/gas, let the system cool, relieve pressure, and drain the heater if needed. Use the correct tool and sealing method (tape/sealant as appropriate). If you’re unsure or it’s a gas unit, get professional help.
Common causes include a failing heating element/burner issue, thermostat problems, scale build-up, or valve/fitting issues. Identify the heater model, then check power/gas supply and inspect for leaks or pressure relief valve problems.
Yes. Different brands/models can use different thread sizes and anode lengths. Always match by model/part number or by accurate measurements.
