Frequently asked Questions:
Q: How much does it cost to install a diesel heater in a campervan, motorhome, or van conversion?
A: Installation costs vary depending on factors like heater brand/model, power output, vehicle/vessel size, complexity of fuel feed, exhaust routing and ducting. According to a UK installer guide, a complete supply + fitting job for a campervan or motorhome usually runs between £700 and £2,500+.
For more basic vans or simpler installs, costs can be lower; for large motorhomes, horse-boxes or marine setups with extra work needed, costs sit at the higher end of that range.
Q: What size heater (kW output) do I need for my vehicle or boat?
A: The heater size depends mainly on the volume of the space (insulation quality, internal volume), usage (occasional camping vs full-time living) and climate (UK winters vs milder seasons). As a guideline: a 2 kW unit is often adequate for small campervans, compact vans or mild-weather use; a 5 kW or higher unit may be required for larger vans, motorhomes, horse-boxes or poorly insulated spaces - especially if planning winter touring.
If you’re planning a boat or narrowboat install or living aboard in cold weather, sizing should consider additional factors (draft insulation, number of cabins, water-heating needs, airflow/ducting requirements) - which makes proper consultation before purchase important.
Q: Can I install the diesel heater myself? Or should I get a professional?
A: While some people do opt for DIY installation, it’s often risky - especially with fuel supply, exhaust routing, combustion-air intake, and ensuring everything is safely installed. Many UK installers strongly recommend professional installation to avoid safety issues, inefficiency or damage.
Professional installation ensures correct fuel line and pump installation, safe exhaust routing, proper ducting, and electrical integration. This is particularly important for narrowboats or marine installs, where compliance with safety standards (e.g. to avoid carbon monoxide ingress) is critical.
Q: Is it safe to run a diesel heater overnight?
A: Yes, but only when installed correctly, with sealed combustion and correctly routed exhaust and intake. For vans, motorhomes and boats alike, that means exhaust fumes must exit safely outside; combustion air should come from a clean, fume-free source; and you should have proper ventilation or a carbon monoxide (CO) alarm.
Many owners do use diesel heaters overnight without issues, but regular maintenance, correct installation and safety checks are essential to ensure ongoing safety and performance.
Q: Can I Have it tap into the vehicle’s main diesel tank for fuel, or do I need a separate fuel supply?
A: Yes, when we install diesel heaters, we can install it so it draws fuel from the vehicle’s main diesel tank via an auxiliary pick-up or standpipe method.
Alternatively, some people prefer us to install a separate auxiliary/“day tank,” especially if they want to avoid depleting their main fuel supply. This approach is often recommended on conversions, vehicles with petrol engines, or where continuous heating may leave little main fuel left.
Q: How often does a diesel heater need servicing, especially on a boat or narrowboat?
A: For boats, narrowboats, and marine installations, as well as regularly used campervans or motorhomes, an annual service is strongly recommended. This helps prevent carbon build-up, ensures the combustion chamber, glow plug, fuel pump, filters and exhaust are clean and functioning correctly, and helps avoid sudden breakdowns in cold weather.
Well-maintained heaters consume less fuel, run more safely and reliably, and have a longer lifespan. For occasional users, if the heater is used rarely, service intervals may be slightly more flexible, but regular inspection is still recommended.
Q: How much diesel does a heater typically use per hour?
A: Fuel consumption depends on several factors: heater size (kW rating), thermostat setting, outside temperature, insulation, and how often the heater cycles on. For example, many diesel air heaters run between about 0.10 to 0.55 litres per hour depending on load and conditions.
For overnight use, or long-duration heating on a boat, it’s worth planning fuel consumption and potentially topping up tanks before colder periods.
Q: Are diesel heaters noisy? Will I be able to sleep while they run?
A: Noise levels vary by heater model, installation quality and how the fuel pump is mounted. Older or lower-quality heater kits can be louder, especially when the fuel pump is directly mounted to a chassis rail or unisolated surface.
Modern heaters and good installations mitigate this, for example, pumps mounted on rubber isolation mounts, insulation around ducting, placing the heater under seats or inside furniture, and ensuring adequate airflow and ventilation.
For boats, additional acoustic ducting and intake/exhaust silencers may be used to reduce noise transmission.
Q: Can I use a diesel heater instead of a gas heating system or electric hookup?
A: Yes, diesel heaters are often chosen as an alternative to gas or electric heaters because they:
-
Use vehicle/boat diesel (no need to carry separate LPG bottles)
-
Draw minimal battery power (usually 12 V) and are efficient even off-grid.
-
Provide reliable heat and often quicker warm-up than electric heaters when no mains hookup is available.
For narrowboats or marine use, diesel heaters are often preferred over gas because of the safety, fuel logistics and overall practicality, especially for liveaboard or extended stays.
Q: Are diesel heaters appropriate for narrowboats, yachts or marine vessels — and what special considerations are there?
A: Yes, diesel heaters are widely used and well-suited for narrowboats, yachts and marine vessels. However, marine installs must follow stricter guidelines:
-
Combustion-air intake must come from a clean, fume-free source (not from living spaces or near fuel storage).
-
Exhaust must be routed correctly, sealed tight, insulated appropriately and exit well above the waterline (or use a swan-neck exhaust) to prevent water ingress.
-
Fuel lines and pumps must be marine-grade, correctly secured and installed safely - especially avoiding tapping into engine fuel supplies to prevent leaks or engine issues.
-
Annual servicing is strongly advised, especially since marine conditions can accelerate wear, fuel contamination or corrosion.
When done properly, a diesel heater gives boat owners dependable, controllable warmth - making winter mooring, cruising, or liveaboard life far more comfortable.
