Even though there is a remote control, it needs to be programmed by taking help from YouTube videos. The instructions provided in English are quite difficult to understand, to be honest.

Buying Guide

So, what are the features that you should look for in the best diesel heater for boats? Scroll down to get an idea!

Construction

Generally, a Chinese diesel heater is made of 304 stainless steel. Since the combustion chamber becomes heated during the operation of the device, stainless steel will keep it from catching fire. 

Diesel is likely to catch fire in the presence of air. Therefore, for a marine diesel heater to keep running for hours, the construction of the device must be considered. 

Nylon and aluminum are also heat-resistant and durable materials that are used to construct this device. Check if any toxic material has been used to build its inner and outer components. Since it’s producing diesel, you don’t want to poison yourself to death. 

Temperature Control

A diesel heater should have a temperature control system that can be manipulated either manually or with a digital remote. 

When you run the device at low temperature, it will use less fuel and warm up the room at an even pace. On the contrary, fuel consumption is higher and the chance of overheating increases when it’s running at a high temperature. 

For safety measures, keep a fire extinguisher, fire alarm, and carbon monoxide detector on the boat to prevent carbon monoxide poisoning. Ventilate the enclosure well for the same reason. 

Number of BTUs

You should calculate the volume of the enclosure before getting a diesel heater for your boat. Ideally, a good boat heater must be able to produce 90 to 180 BTUs per cubic meter of space. 

If the specifications are not given, just multiply the watts of the diesel air heater by 3.4 to find out its BTUs. 

Noise Level

You don’t want to have an indoor diesel heater if it’s noisy. The last thing you want is the sound of fans spinning when you’re deeply asleep. For that reason, most diesel heaters in this article come with mufflers to prevent noise. 

Heat Output

Rest assured, all the heaters I have reviewed here are capable of spreading heat evenly into the enclosure. It provides comfort in the colder days and also dehumidifies glass windows. 

To find out the heat output level of a diesel heater, check its power and current units. A good diesel heater should have a power of 12V at 5 kilowatts.

On top of buying a boat heater with high heat output, also consider insulating the boat with closed-cell foam and foil barrier. It will prevent cold air from coming inside the chamber and stop warm air from leaving. It also helps mold and mildew from not forming inside the enclosure. 

Cost

There is a number of options to choose from when it comes to its pricing. The Chinese diesel heaters are cheaper than European heaters. However, the functionality, ease of use, and heat output of the devices can’t be judged by their costs. 

In the affordable range are Happybuy and Tseipoaoi .

Fuel Consumption

I’m content to say that my carefully chosen list of diesel heaters is all friendly on fuel consumption. Since diesel is the core element, it burns slowly, producing maximum heat output, and lasts a long time.
The diesel heaters for boats with the most efficient fuel consumption system are Eberspacher, Tuningsworld, and VEVOR.

Frequently Asked Questions

Since it involves a diesel heater, a very technical device, you are sure to have a bunch of questions. Yes, I get it. So, here are a few of them answered.

  • Are Chinese diesel heaters safe?

Most Chinese diesel heaters are made from lower-quality materials and are usually not as safe as standard quality boat heaters. However, there are people who love and buy these Chinese diesel heaters without reporting any issue. 

These devices also produce less carbon monoxide than their gasoline counterparts. Because they run on diesel, you can keep them on at night and sleep without worry. But if your Chinese diesel heater doesn’t include an auto shut-off feature, don’t fall asleep with it turned on!

  • How efficient is a diesel heater?

A diesel heater is one of the most efficient options to consider. It only consumes about 0.11 to 0.51 liters of diesel per hour. 

These heaters can warm up the room in only 30 minutes. Some can even do so quicker! They are economical, easily obtainable, and produce slow and steady heat for even temperatures everywhere. 

Fuel consumption of a diesel heater can vary depending on the altitude, ambient temperature, and construction quality of the heater. Typically, it will be using about 100 ml of diesel per kilowatt.

  • How much electricity does a diesel heater use?

When you’re just starting the diesel heater or shutting it down, it pulls upto 11.5 amperes of current at 12 volts. That is why the running cost of a diesel heater is sometimes considered insignificant.   

It usually sources electricity from the boat’s diesel tank, power source, or battery. The electricity that it pulls from the power source is to run the fan and thermostatic controls.

  • Can you mount a Chinese diesel heater on its side?

If you mount a Chinese diesel heater on its side, the fuel may leak from the glow plug. If you’re considering it to be mounted on its side, know that it’s dangerous. 

The boat heaters on my list are small. Hence, you should not have the problem of a lack of space. You can get just mount them upright (the way it’s supposed to be).

  • Can I mount the diesel heater vertically?

When a diesel heater that is supposed to be mounted upright is mounted vertically, you may experience some problems, including diesel leaking. 

Unless you’re a professional heater technician, you shouldn’t even attempt to do something abnormal and dangerous. Just stick to the rules, please!

To Finalize

So, what did you think of all the diesel heaters I thought are ranking well in the market? Did you find something that you like?

Your opinion may differ from mine. But in my opinion, Eberspacher Boat Heater is the overall best diesel heater for boat. It’s fuel-efficient, has an altitude detector, uses less energy, has a fault diagnostic feature, and a timer!

Happybuy and Tseipoaoi are good picks if you are looking for a budget-friendly heater. They are Chinese products, but you won’t be disappointed once you begin to use them. 

Also, you can get Tuningsworld and VEVOR for the most efficient fuel consumption mechanism. You want to use as little fuel as possible if you’re camping and traveling to different altitudes. 

In all, that is all for now. I hope you take care till my next review!
