The Jacgood 5000W-8000W diesel parking heater is a 12V air heater that runs on diesel only. It comes as an all-in-one kit with a remote control, an LCD display and a muffler.
It heats around 15m² and can run for up to 48 hours without a break. Fuel use is 0.64 L/h and power use is 0.036KW/H. It suits vans, RVs, trucks, buses, boats and car trailers.
The body is sand-blasted aluminium. The kit includes all mounting screws and instructions. The heater works from -40℃ to +50℃ and at up to 3,500 metres above sea level. At £86.99 it is a low-cost way to heat a garage or cab.
Sand-blasted aluminium body - What is it made from? The combustion chamber, base and heat-dissipating scale are all aluminium and formed as one piece. Aluminium passes heat to the air quickly. That gives even heat from the outlet and a fast warm-up. One piece also means fewer joints that can work loose.
Remote control - Can you start it from indoors? Yes. The remote works within 30 metres. You can change the temperature and switch the heater on before you walk out on a cold morning. The LCD display also shows settings on the unit itself. It is useful in a garage or van.
Low running costs - How much does it use? Fuel use is 0.64 L/h and power use is 0.036KW/H. A frequency conversion ECU controls how often the oil pump injects fuel and how much air comes in. Tighter control means less wasted fuel. Startup draws 15A and running current is 3A.
Quieter running - Is it loud? Blower speed control, a silent fan, a silent oil pump and the muffler all cut noise. The metering pump uses a low-frequency pulse with low vibration. Some reviewers still report pump ticking and a louder warm-up. Mounting the pump on a metal chassis can add noise.
Complete installation kit - What is in the box? You get the mounting screws, muffler, remote, LCD monitor and instructions. The fuel pump must sit upright and tilted between 40 and 90 degrees. To start the heater you need to hold the up and down keys for a few seconds to prime the fuel.
Wide working range - Where can you use it? The heater works from -40℃ to +50℃ and up to 3,500 metres above sea level. The oil pump works from -40℃ to +40℃. It can supply heat for up to 48 hours and warms around 15m². That covers cabs, garages, boats and trailers.
The fuel pump must be mounted up and kept tilted between 40 and 90 degrees. One reviewer reinstalled theirs vertically so the pump would be lubricated and last longer. A tilted or flat pump may cause fuel delivery problems. Check the angle before you fix it in place.
The most common cause is fuel that has not been primed. Several reviewers found the manual does not say so. On this controller you press and hold the up and down keys for a few seconds to prime the pump. Without this the heater will not start properly. A weak battery is another cause. The startup current is 15A and one reviewer measured around 10 amps. Use a strong battery or power supply.
The remote works within 30 metres. You can adjust the temperature and start the heater before you get into the vehicle on a cold morning. Walls and other obstacles may reduce that range in real use.
It uses diesel only. Consumption is 0.64 L/h. At that rate a 5-litre tank lasts a little under 8 hours at full output. Reviewers describe it as economical and say it sips lightly on the diesel. The listing states a continuous heat supply of up to 48 hours.
The heater works from -40℃ to +50℃. The oil pump works from -40℃ to +40℃. The maximum working altitude is 3,500 metres above sea level. This covers UK winters and mountain use without trouble.
Yes. The listing says it suits cars, buses, RVs, trucks, engineering vehicles, boats and car trailers. It heats the cab or cabin through an air outlet. One reviewer suggested buying a version without a tank for vehicle fitting. A tank of diesel is bulky to bounce around inside. Mount it securely and keep the exhaust clear of anything that can melt or burn.
The exhaust gets very hot. One reviewer warned that the pipe must not touch anything flammable or meltable. The exhaust must also vent outside. Check pipe connections and clips before first use. One reviewer reported smoke from the exhaust after about 5 days and called the unit dangerous. Another noted the warm-up phase makes smoke. Test the heater outdoors or with the door open first and watch the first few runs.
Installation scored well. Of 9 mentions, 8 were positive. Reviewers said all parts were supplied and fitting needed no special knowledge. The instructions are the weak point. It is sold by JACGOOD and sent from Amazon. Amazon offers a 30-day right of return on many products. Deliverability outside mainland UK is confirmed at checkout. The heater cannot be shipped to some places.
The Jacgood 5000W-8000W Diesel Parking Heater Kit is a 12V diesel air heater sold as an all in one kit. It comes with a remote control, an LCD display and a muffler. Amazon.co.uk lists it under Car Ignition and Heating Systems (ASIN B0BLYVF9WR). It was first available on 10 November 2022. It is sold in black or red and the listing price is £86.99 including VAT. Amazon also shows £66.99 with a Gift Card if approved for the Amazon Barclaycard. The seller is JACGOOD and the item is sent from Amazon Fulfilment. Amazon says over 100 were bought in the past month.
The heater output ranges from 5KW to 8KW and runs on 12V. It uses diesel only. Fuel consumption is 0.64 L/h and power consumption is listed as 0.036KW/H. Startup current is 15A and rated current is 3A. One buyer says it needs a strong power supply or battery to start and puts the draw at around 10A. The listing says it heats about 15m² and can supply heat for up to 48 hours without a break. It works at altitudes up to 3,500 metres above sea level.
The heater works in temperatures from -40°C to +50°C. The oil pump works from -40°C to +40°C. The fuel pump must be fitted upright and kept tilted between 40 and 90 degrees. One buyer fitted the pump vertically so it would be lubricated and last longer.
The combustion chamber, the base and the heat-dissipating scale are sand-blasted aluminium parts. They are formed as one piece. The maker says this gives even heat dissipation and fast heat. The air outlet is large at 7.6 cm across and the air inlet is 2.6 cm across. The listing says the turbine wind speed is even and the air volume is large. The fuel pump is a plunger type. The maker says it pulls fuel with stronger suction and gives a steady fuel supply.
An optimised frequency conversion ECU controls the injection frequency of the oil pump. It also controls the amount of air taken in by setting the fan speed. The maker says this extends the life of the heater.
The maker reduces noise with blower speed control, a silent fan, a silent oil pump and a muffler. The metering oil pump uses an improved low frequency pulse with low vibration. Amazon customers have mixed views on noise. 17 reviewers mention it. 7 are positive and 10 are negative. Some buyers call it fairly quiet. One says the pump ticking can get irritating. Another says the fuel pump is a little noisy when mounted to a metal chassis. One buyer says it is noisy at first but settles down. One says the warm-up phase is fairly loud and makes a lot of smoke.
The remote control works within 30 metres. You can change the temperature remotely and start the heater before you get into a cold car. The LCD display shows the heater status. Two buyers say the instructions are poor and the controller is confusing. Two buyers say you must hold the up and down keys for a few seconds to prime the fuel pump or the heater will not start properly.
The package measures 51 x 49 x 21 cm and weighs 8.8kg. One buyer says the supplied exhaust tube is very short. Another says the air intake and exhaust were labelled the wrong way round. A third replaced the fuel line with a kit costing about £8 because the original kinks easily.
The maker says it can heat the cab of diesel vehicles such as cars, buses, RVs, trucks, engineering vehicles, boats and car trailers. Buyers also use it in garages, workshops, awnings, a garden shed and a container unit. One buyer heated a container unit measuring 15ft x 10ft (about 457 x 305 cm). They say it takes about 3 hours to reach around 16°C.
The product has 334 ratings with an average of 4.2 out of 5. The split is 68% 5 star, 13% 4 star, 4% 3 star, 3% 2 star and 12% 1 star. Amazon ranks it 3,073 in Automotive and 9 in Car Ignition and Heating Systems.

Several buyers report that the heater cuts out. One reports an E-8 error code. One mentions a faulty motherboard and one a collapsed tank. One reports smoke from the exhaust after about 5 days. One says the case clips came off and the Jubilee clips fell apart when tightened. Other buyers say it is cheap to run and gave strong heat from the first start. One reviewer says it has run well for a second year. One reviewer who rebuilt it replaced the hoses with rigid nylon and redid the wiring. Reviewers warn that the exhaust gets very hot and must not touch anything flammable or meltable.
