Truma Combi 4E installation kit with iNet X
This Truma Combi 4E package combines 4 kW space heating and a 10 litre hot-water system in one compact appliance for caravans, motorhomes and campervans. The kit is centred on the Truma 33714-20 heater and includes the iNet X control panel plus core flue, water and warm-air outlet components.
Run it on LPG when travelling off-grid, on 230 V electricity at a powered site, or in mixed mode when you want faster heating. Order online for delivery across New Zealand, or contact the Select Caravans team in Auckland for product and compatibility guidance.

Installation and NZ gas safety
This is a fixed LPG appliance. In New Zealand, gasfitting work on caravans and motorhomes must be carried out and certified by an authorised person. Your installer must confirm appliance suitability, ventilation, flue position, service access, electrical supply, water-system pressure and compliance for your particular vehicle.
Frequently asked questions
Is this the full installation kit?
It includes the heater, iNet X panel and the core items listed above. Vehicle layouts vary, so 65 mm warm-air ducting and other installation-specific parts may still be required.
What is the difference between this kit and the heater-only product?
This RVC860 package adds core installation components around the Truma 33714-20 heater. If you already have the required flue, water and air-distribution parts, compare the Truma Combi 4E heater-only option.
Can it heat water without heating the cabin?
Yes. In summer mode, the Combi 4E can heat water without running the space-heating function.
Can I install it myself?
The fixed LPG installation and certification must be handled by an appropriately authorised New Zealand gasfitter. Electrical and other work should also be completed by suitably qualified people where required.
