12V Diesel Air Heater

From: Prijesse

This 12V 5kW parking heater runs on diesel and works without the engine on. It pulls air from outside, burns it with diesel in a sealed chamber and blows the warmed air into your space. The Prijesse diesel air heater costs £71.99 and comes as a split type in black or red.

What does it heat? It covers about 15m² and fits vans, caravans, boats, trucks and even sheds or workshops. It runs for up to 48 hours on a single supply of heat and works from -40°C to +50°C.

The box holds a 10L tank, LCD thermostat, silencer, remote control and a full mounting kit. Fuel use starts at just 0.14L per hour.

Product Features

5kW Heat Output - The 5000W output covers around 15m², which suits a van, caravan or small workshop. How fast is it? One listing claims a small car reaches 72°F in 8 minutes from 35°F weather. A reviewer took a VW Crafter to 26°C in 20 minutes. That is quick for a 12V unit. Low Fuel Use - Fuel use runs from 0.14L to 0.64L per hour. The motherboard controls the mix of air and diesel to save fuel. One reviewer used about 1 litre of diesel per day in a campervan on a low setting. Power draw is only 0.036kW per hour, with a 15A startup current and 3A rated current. Works Without the Engine - Why does this matter? You can heat your vehicle while parked and the engine stays off. Air is drawn from outside and burned with diesel in the chamber. Heat passes through the aluminium shell and a fan blows it out. It can also preheat engine coolant, which cuts wear on cold starts.

Remote and LCD Control - The remote works within 30m, so you can start the heater from the house on a frosty morning. The LCD thermostat sets the temperature. The remote has no batteries included. Tip from reviewers: hold the up and down keys together to prime the fuel pump. Noise Reduction - A silencer, silent fan and metering oil pump with low frequency pulse help keep noise down. Is it silent? Not fully. Reviews are mixed, with 5 positive and 7 negative mentions on noise. The fuel pump ticks, so mount it outside the cabin and insulate it. A silent pump swap is a common fix. Full Kit and Wide Use - The kit includes the heater, silencer, LCD thermostat, remote, 10L tank, wire bundle, 2 vents, 2 air outlet pipes, intake and exhaust pipes, oil pump, fixed plate, oil pipe, nozzle, tee, fastener, oil extractor and screws. It works up to 3,500 metres altitude and weighs 10kg. Several reviewers advise replacing the supplied clips.

FAQs

Can I run it without the engine on?

Yes. It runs from its own diesel tank and the 12V battery. The engine does not need to be on. The 3A rated current is low and one reviewer used only a couple of amp hours for about an hour of running. Make sure the battery keeps enough charge for the cooling cycle at shutdown.

How much diesel does it use?

The listing gives 0.14 to 0.64 L/h. The low end is for the lowest setting. A buyer in a Vauxhall Vivaro used about 1 litre per day over five days of campervan use. Running on setting 1 uses far less than full output. Tuning with a CO2 meter may cut waste further.

Is it loud?

The heater itself is about as loud as a car blower on a middle setting for some buyers. Others found start-up very loud. The fuel pump ticks and this is the most common complaint. Mount the pump outside the cabin or insulate it. The pump has to stay tilted between 40 and 90 degrees. A silencer comes in the box.

Does the remote come with batteries?

The listing says no. One buyer found a battery already fitted and it worked without pairing. Others could not pair it and found no instructions. One said a 12V battery that fits the remote was hard to find. Check the battery type when it arrives and buy a spare.

How do I prime the fuel pump?

Hold the up and down keys on the LCD controller at the same time. The manual does not cover this, so several buyers lost time on it. Prime before first use so fuel reaches the heater. Skipping this can cause the fuel pump to appear faulty.

Is the 10L tank too big for a van?

It can be. One Vivaro owner could not find space for it and bought a 2.5 litre tank. Another used a water bottle as a fuel container in a VW Beetle. The tank measures part of the 10kg package weight, so check the space under your seat or floor before fitting.

Will it work in cold weather and at altitude?

The heater works from -40°C to +50°C. The oil pump works from -40°C to +40°C. It works up to 3,500 metres above sea level. That covers most UK use. A buyer ran it at 4°C outside and got ample heat on the lowest setting.

Is it only for vehicles?

No. The 15m² heating area suits small spaces. Buyers use it in a shed, a greenhouse, a workshop and a caravan. One owner runs one in the shed and one in the camper. For an outbuilding, a reviewer suggested mounting the main unit outside and piping the warm air in.

PRIJESSE Diesel Air Heater Specs

Prijesse diesel air heater Specs

## PRIJESSE 12V 5KW Diesel Air Heater (Split Type, Black) The PRIJESSE 12V 5KW diesel air heater is a parking heater for vehicles and small buildings. It burns diesel only and runs from a 12V supply. The listing gives the heater power as 5KW (5000W) and the model as TSD-2 (12V 5000W). The manufacturer part number is PR-15-1. It is sold in black or red and in two layouts: all-in-one or split type. This page covers the black split type. ### How it works The heater does not need the engine to be running. It draws combustion air from the surroundings and diesel from the fuel tank. The two mix in the combustion chamber. The heat from burning passes through the aluminium shell. A fan then blows the hot air into the space being heated. This lets it work as a stand-alone unit while parked. It can also preheat engine coolant, which helps prevent engine wear when starting in low temperatures. ### Performance The listing says it can warm a small car from about 2°C to 22°C in 8 minutes. The heating area is 15m². It can supply heat continuously for up to 48 hours. The heater works in temperatures from -40°C to +50°C. The oil pump works from -40°C to +40°C. The heater can work at up to 3,500 metres above sea level. Fuel use starts at 0.14L per hour and reaches 0.64L per hour at the top setting. Power consumption is 0.036KW per hour. The startup current is 15A and the rated current is 3A. The mother board controls the ratio of combustion air to diesel to save fuel. One reviewer used about 1 litre of diesel per day in a Vauxhall Vivaro. Another reached 26°C in a Volkswagen Crafter in 20 minutes. A reviewer measured exhaust temperatures of 200°C or more and advised using exhaust wrap. ### Controls A remote control lets you change the temperature and start the heater before you get to the vehicle. Its range is 30 metres. The remote does not come with batteries. Some buyers said their remote arrived with a battery fitted. An LCD thermostat controller is included. Reviewers said the pump is primed by holding the up and down keys together. One said the priming button for the pump is also on the display. ### Build The fuel pump is a plunger type. The listing describes it as precise and sensitive with strong suction and a stable fuel supply. It must be mounted with the pump up and tilted between 40 and 90 degrees. The base has a high temperature resistant cushion to protect it from damage. The internal parts are fully blasted aluminium sand parts for even heat spread and resistance to ageing. A silencer is included. The fan speed is controlled and the fan and oil pump are described as silent. The metering oil pump uses a low frequency pulse with low vibration. The listed size is about 38.9 x 14.5 x 14.5 cm. The item weighs 10kg. The package measures 40 x 16 x 16 cm. The outlet diameter is 76mm and the inlet diameter is 26mm. ### What is in the box - 1 x air heater - 1 x silencer - 1 x LCD thermostat - 1 x remote control - 1 x 10L tank - 1 x wire bundle - 2 x vent - 2 x air outlet pipe - 1 x intake pipe - 1 x exhaust pipe - 1 x oil pump - 1 x fixed plate - 1 x white oil pipe - 1 x oil nozzle - 1 x tee - 1 x fastener - 1 x oil extractor - 1 x installation parts A full mounting kit is included with all mounting screws and instructions. The listing notes that the manual is a generic version. One reviewer said the air ducting supplied is only about 1.2 metres long. ### Uses The heater can warm the cabins of cars, RVs, vans, buses, trucks, recreational vehicles and engineering vehicles. It can be removed and fitted to a new vehicle. It can also heat homes and shops. Reviewers have fitted it in campervans, a caravan, a boat, a Land Rover, a classic VW Beetle, a shed, a workshop and a greenhouse. ### Installation notes from reviewers - One reviewer cut a hole of about 7cm by 10cm in the floor for the three pipes and four bolts. They then sealed the hole and bolted the plate and heater down together. - Several reviewers said the supplied jubilee clips and pipe clamps are poor and replaced them. - The installation instructions were called hard to follow by several reviewers. One said they were written for a different model. - Reviewers said to bleed or prime the fuel system before first use. - Some reviewers saw white smoke on the first start. - The 10L tank was too big for one reviewer. They fitted a 2.5 litre tank instead. - One reviewer said an adapter or a piece of ducting is needed to fit a Y pipe to the hot air outlet. - One reviewer warned the car battery should have enough charge for the shutdown cycle. The glow plug and fan run at shutdown to clean and cool the unit. - Reviewers said the ducting gets very hot at full output. ### Noise Reviews are mixed. One reviewer said the heater is about as loud as a car blower on a middle setting. Others said it is very loud on start up and at full output. Several said the fuel pump ticks or taps and is best mounted outside or insulated. One reviewer swapped the pump for a silent type. ### Delivery and returns The seller is PRIJESSE.
