Diesel Heater Supply & Installation

Warm your campervan with a heater selected for its space and use. SP88 offers diesel heater supply and fitting, customer-supplied heater installation and fault finding across South London and nearby Surrey.

AUTOTERM heater installation

AUTOTERM products: supply only or installed

Ask SP88 for a supply-only quote for an AUTOTERM heater kit, or choose supply and fitting together. We confirm the exact heater, voltage, controller, kit contents, availability and warranty terms before taking payment.

Send the product link for any larger heater, controller, ducting, outlet vent or replacement part you need. Supply and fitting suitability are assessed individually; the 2D/4D installation prices do not cover every model.

Request an AUTOTERM product or fitting quote

Manufacturer links are ordinary reference links. Manufacturer checkout is separate from an SP88 order.

Ask about AUTOTERM Air 2D, Air 4D and other models appropriate to your vehicle. Bigger is not automatically better: insulation, internal volume, typical conditions and duct layout all affect the choice.

The AUTOTERM Air 2D provides 0.8–2.0kW of heat; the Air 4D provides 1.0–4.0kW. Both have separate 12V and 24V versions. The choice depends on the heat demand of your conversion, rather than choosing the highest output. See the Air 2D manufacturer specifications. We confirm the correct voltage, kit, mounting position, fuel supply and ducting before quoting.

Already bought a Chinese diesel heater?

We can assess customer-supplied Chinese diesel heater kits for installation. Send the brand, model, voltage, manual and photographs of everything included before booking fitting.

Missing or unsuitable exhaust, fuel, wiring or mounting parts may need replacing and will be listed in the quotation. Installation depends on the kit being suitable for the vehicle and having enough information to fit and test it safely. Workmanship and the equipment supplier’s product warranty are separate.

What the installation covers

Your quotation sets out the agreed heater and fitting parts, mounting work, fuel connection, electrical supply and protection, combustion air/exhaust routing, warm-air ducting and controller position. Installation and operating checks follow the exact heater’s instructions.

We plan combustion exhaust away from openings and fresh-air intakes, protect surrounding materials and check access for servicing. A suitable carbon monoxide alarm should be part of the vehicle’s safety equipment.

Heater wiring, ducting and running faults

Contact SP88 about starting problems, electrical cut-outs, controller faults, poor warm-air delivery or an existing installation needing assessment. Send any fault code and details of what happens at start-up. A low battery voltage at the heater or a poor connection can interrupt operation even when there is fuel available.

Supply and fit, or fitting only

Diesel heater fitting prices

AUTOTERM Air 2D — supply and fit from £995; labour-only fitting from £450.
AUTOTERM Air 4D — supply and fit from £1,195; labour-only fitting from £450.

Labour-only prices apply to customer-supplied equipment; additional installation materials are quoted separately. Supply-and-fit starting packages cover a straightforward internal installation, standard controller, one warm-air outlet, fuel connection and commissioning. External mounting, extra outlets and difficult access are quoted separately. Allow one fitting day.

Customer-supplied heater fitting: labour from £450. Suitable Chinese heater kits are welcome following assessment. Any additional installation materials or replacement kit parts are quoted separately. Allow one fitting day.

Assessment, booking and payment

Start with a free WhatsApp photo assessment. Where a vehicle inspection is needed, the assessment costs £100, credited against an installation booked within 30 days. After we agree the specification and total price, the fitting deposit is £100 for labour-only work or 30% for supply and fit. The balance is due after installation and testing. Fitting dates are confirmed after assessment; sending an enquiry does not reserve a date.

Supply and fit: we assess the vehicle and quote a suitable heater with the installation parts and labour.

Customer-supplied fitting: we review the kit first and quote labour plus any necessary additional parts.

Tell us your vehicle, postcode, preferred heater and intended mounting area. Installation dates and total cost are confirmed after the assessment.

Heating needs dependable leisure power

A diesel air heater uses fuel for heat but still needs electrical power for starting, controls and its fan. Battery condition and charging matter on longer stays. Combine a heater installation with a leisure-power assessment where needed.
