Find the right caravan hot water system or spare part for your van. Start with a complete gas, 240V, 12V/240V or instant hot water system, or match parts for Suburban, Truma, AquaGo, Camec, Girard, Atwood and Duoetto units.
Shop Hot Water SystemsChoose complete systems if the heater is being replaced. If the heater is staying in the van, start with the brand, model or diagram sections so the part matches what is already fitted.
If you are new to caravan hot water systems, the easiest place to start is with one question: are you replacing the whole heater, or are you trying to fix the one already in the van?
If the whole heater needs replacing, browse complete hot water systems first. A storage-tank system is usually the simplest replacement when the caravan already has a Suburban, Truma UltraRapid/B14 or similar tank-style heater. Match the capacity, power type, door or cowl colour and wall opening before comparing brands.
An instant hot water system suits people who want continuous hot water, but it is not always a straight swap for a tank heater. Before changing styles, check gas supply, venting, water flow, wall thickness, door size and 12V control requirements. For a broader overview of the main options, read the Suburban vs Truma hot water guide.
For most replacement jobs, copy the important details from the old heater: brand, model code, tank size, gas-only or gas/240V, door or cowl colour, and the cutout size. Use the storage-tank comparison if you are comparing Suburban, Truma, Duoetto, Global Heritage and similar units by capacity and power type.
Do not assume every heater with a similar door will fit. Pipe positions, depth, wall opening, cowl style, wiring and service access can all affect the job. Gas and 240V work also need the right qualified trades.
If the heater is staying in the van, find the brand and model label before buying parts. Once you know what is fitted, use Suburban hot water parts, Truma hot water parts, AquaGo parts or water heater diagrams to narrow the search.
Suburban tank heaters commonly need anodes, 240V elements, pressure relief valves, thermostats, doors, switches and boards. The anode is a normal service item on many Suburban tanks, so read the Suburban maintenance guide before replacing the whole heater because of poor performance.
A part that looks close is not always the right one. Truma UltraRapid/B14 storage heaters do not use the same parts as Truma AquaGo instant heaters. Camec, Girard, Suburban Nautilus and Suburban ST60 instant heaters also have their own doors, sensors, burners, controllers and service parts. If you are not sure, match the model number against the diagram or manual before ordering.
Use these paths to choose between a complete heater, instant hot water, storage tank replacement or spare part for the model already fitted.
The first decision is usually storage tank or instant hot water. The best caravan hot water system depends on how the van is used, the space already available, the gas and power setup, and whether you want a direct replacement or a different style of heater.
| Hot water type | Best for | Power options | Watch-outs |
|---|---|---|---|
| Storage tank HWS | Replacing a familiar tank-style heater such as Suburban, Truma UltraRapid/B14, Global Heritage or similar caravan hot water systems. | Gas only, gas/240V, 240V-only or mixed power depending on model. | Tank capacity, door or cowl colour, wall cutout, element or anode requirements, pressure relief valve and exact SW/B14 model. |
| Instant gas HWS | Continuous hot water when the caravan layout suits the vent, door, water flow and gas requirements. | Gas heating with 12V controls on many caravan instant systems. | Water flow, venting, gas compliance, door size, freeze protection, wall thickness and whether the brand has matching spare parts. |
| 12V/240V electric HWS | Compact electric hot water where a small-capacity unit such as Duoetto suits the available space and electrical supply. | 12V, 240V or dual input depending on unit. | Capacity, current draw, wiring, mounting and whether electric-only heating suits how the van is used. |
Most wrong hot water orders come from a small mismatch: model suffix, door colour, cowl, capacity, power setup, wall cutout or service part. These are the details worth confirming before you buy.
Caravan hot water system spare parts are often model specific. A valve, door, board, sensor, element or fitting can look close but suit a different storage-tank or instant heater.
| Brand or model | Use for | Check carefully | Best next step |
|---|---|---|---|
| Suburban SW series | SW4/SW5/SW6 tank systems, including anodes, elements, thermostats, valves, doors, boards and SW6DEA/SW6DERA diagrams. | Model suffix, door colour, gas/electric type and anode/element fit matter. | Start with Suburban parts, then use the maintenance guide or diagram if the part is not obvious. |
| Truma UltraRapid / B14 | Truma tank systems, including cowls, covers, elbow fittings, elements, PCBs, sensors, burners and manuals. | B14, UltraRapid and AquaGo parts are not interchangeable. | Use the Truma B14 parts and diagram paths before ordering look-alike parts. |
| Truma AquaGo | Instant Truma hot water systems, decalcification tablets, door panels and AquaGo service parts. | AquaGo is an instant system, not a Truma storage-tank heater. | Use AquaGo parts and manual links rather than guessing from Truma storage-heater parts. |
| Camec / Girard instant | Instant gas heaters, doors, ventilators, sensors, burners, valves, control units and manuals. | Door size, wall thickness, model generation and spare-part diagram must match. | Use the instant hot water comparison and diagrams before choosing parts. |
| Duoetto / compact electric | Compact electric hot water systems where the 12V/240V supply and capacity suit the van. | Capacity, current draw, wiring and mounting are the main fit checks. | Check the product page and install manual before fitting. |
If you already have a heater in the caravan, start with the brand and model label. These guides and diagrams help compare systems, confirm service parts and avoid parts that only look similar.
Helpful when you are comparing caravan hot water systems, troubleshooting a known model, or checking a part before you buy.
Use these shortcuts once you know whether you need a complete caravan hot water system, a brand-specific spare part or a diagram.
The best caravan hot water system depends on whether you want a storage tank or instant hot water, what power and gas setup the van already has, the available cutout, and whether you need a complete replacement or service parts.
Storage tank systems such as Suburban and Truma UltraRapid suit many direct replacement jobs. Instant systems can provide continuous hot water but need careful checks for gas, venting, flow rate, wall thickness and door size.
Common Suburban service parts include anode rods, 240V elements, thermostats, pressure relief valves, doors, switches, probes, boards and fittings. Check the SW model code before ordering.
No. Truma UltraRapid/B14 storage systems and Truma AquaGo instant systems use different parts. Use the model name, manual or diagram before ordering.
Some tank systems, especially many Suburban models, use an anode rod as a service item. Not every HWS uses the same maintenance parts, so check the manual and model before buying.
A hot water system can involve gas, 240V, 12V, plumbing, venting and pressure components. Use the install manual and qualified trades where gas, electrical or compliance rules apply.
No concerns with the mechanisms for delivering the part, it arrived quickly and conveniently at the local post office but the $10 delivery cost for a $10 component no bigger than a medium size screw was excessive. This may be the standard delivery cost but this needs to be reviewed by administration within your company.
Excellent service and product
Very fast turn around. Item as expected. Will purchase from.here again.
