Ruiangaore Diesel Heater 12V 7kW (All-in-One Water-Air)

How does the dual heating system work?

The heater combines air and water heating in one unit. It heats air for immediate warmth in living spaces whilst simultaneously heating water for domestic use. The system prevents dry burn by maintaining water circulation, making it safer than air-only heaters. You can operate both functions together or independently depending on your needs.

What fuel consumption can I expect?

In standard mode, the heater consumes approximately 1 litre of diesel per 24 hours at sea level. The fuel-saving mode reduces consumption by 43%, bringing usage down to around 0.57 litres per day. Actual consumption varies based on outside temperature, desired heat output and operating altitude.

Is installation difficult for beginners?

Installation requires experience with diesel heating systems. The unit needs proper fuel lines, exhaust ducting, electrical connections and water circulation setup. Many users report inadequate installation instructions, so previous experience with similar heaters is recommended. Consider professional installation if you're unfamiliar with diesel heater systems.

How loud is the heater during operation?

The heater operates at under 45 decibels, similar to a quiet library or soft rainfall. This makes it suitable for overnight use in campervans or boats. The motor runs at up to 5900 RPM but sound dampening keeps noise levels low. Most users find it quiet enough for sleeping areas.

What maintenance does the heater require?

The automatic cleaning cycle removes carbon deposits every 30 minutes of operation, reducing manual maintenance. Regular tasks include checking fuel filters, cleaning the combustion chamber periodically and ensuring proper ventilation. The LCD display shows error codes to help diagnose any issues that arise.

Can it heat water to usable temperatures?

Yes, the water heating function provides hot water suitable for washing, cleaning and basic domestic needs. The system circulates coolant through a heat exchanger to warm your water supply. Water temperature depends on flow rate and ambient conditions, but it reaches practical temperatures for campervan use.

What power supply does it need?

The heater operates on 12V DC power, drawing from your vehicle's battery system. It includes aviation-grade plug connectors for secure electrical connections. You'll need adequate battery capacity and charging capability to run the heater for extended periods, especially overnight.

Does it work at high altitudes?

The heater functions from sea level up to 6000 metres altitude. Some users report better performance using the high altitude setting even at sea level, which can improve fuel efficiency. The automatic mode adjusts combustion parameters based on operating conditions to maintain optimal performance.
