8KW Diesel Heater, 12V Diesel Air Heater with Bluetooth Remote Control and Smart APP

Have this installed now about a week and it has done a great job in my 6.5m sprinter. Temps got down to -3C this week and I had this set on level 3 keeping a fairly constant 20c internal temp with the roof vent open and some fairly big air leaks around both the back and side doors respectively. The app makes using it a lot friendlier than previous non Bluetooth versions. Ability to easily set a timer is a nice touch. Easy to fit, good value for money. The only slight issue is the pump which I found to be a little noisy on the lowest setting. If I had a smaller van, I would maybe opt for a 2kw version. It’s not actually good to run these units on low constantly and I find they give the best heat around setting 3 or 4. They get very hot at level 5 and 6 but it’s nice to use when you want to warm the place quickly. The controller also gives the option to set a specific temp, however I find this function can be a bit temperamental and caused mine to constantly change from level 1 to level 5 which can be a bit annoying when going to bed, therefore I just set mine on level 3 or 4 depending on outside temp. Final note if installing these in a vehicle, make sure when you park up that you aim the exhaust away and upwind of the air intake. You really do need the fumes exiting the side or back and blowing away from your vehicle. If using overnight, You also need to check if the wind direction is going to change by morning as they can not only cause fumes to enter the cabin, but also cause a flameout. This is all from experience with other models and so far I have not experienced a single error code on this unit.

Install was easy and self explanatory, seen comments about fuel line clips not being great and replacing them but to be honest the fuel line fits so tight I dont think upgrading the clips is necessary.I have 2 other diesel heater which are both self contained (free standing with built in fuel tank) as I thought they would be easier to install but have now swapped to this type as it takes up a lot less room as fuel tank can be installed in location of you choose.Once installed the heater fired up on 3rd attempt (once fuel had found its way to pump) and the heater fired up and started producing masses of heat.Can’t fault this product so far.

I have had a cheap Chinese diesel heater for the past 3 years ago. I payed £80 for it. Fantastic heater that eventually failed on me after 1000's of hours use. Always hot even on temp H1 you could not put your hand in fromt of the blower for too long. Your hand would start to burn. My last unit was a 5KW heaterReplaced it with this unit, supposedly an 8KW unit. The size, weight and dimensions were exactly the same as my old 5KW unit. So I am not to sure it is 8KW, Label does not state the power like my last one.Fitted very easily as it everything was the same as my old unit. Even the wiring was the same and connectors the same. To be on the safe side all the wiring was replaced with the new loom.The heater worked straight away, but it was no where near as warm as my last heater. My hand could be held close to thew outlet vent and my hand did not burn, even after 60 seconds. Even after 1 hour on H6 my van was no where near as warm as it used to be.Not sure if it is a faulty unit or I have got a 2KW version, but I will be asking for replacement or refund.The bluetooth and the timer works fine though and would be useful.

easy to assemble & set up. complete installation kit supplied in the kit, everything you need to get it running.This is a Hcalory "re-branded" as KROAK so the quality of the parts is above average, for example the exhaust clamps are stronger than cheaper models and did not strip when tightened.The app was easy to download and install (search Hcalory) and the manual is pretty good too, easy to understand.

Installed this a couple of months now on our boat, only just started to use it now colder weather is here and it’s doing a great job. Highly recommended for the price. Hope it lasts

Within 2 days of fitting the rubber pomp housing split in two causing the pump to hang down and the fuel line touched the exhaust and melted spilling diesel all over the exhaust and the road . I also find this model extremely noisy compered to my previous one

Fingers crossed with this manufacturer as I've tried 4 others this year already all failed. Reviewed well. Install was easy, set up easy. Fan noisy, not as hot as previous heaters, I don't believe it's 5kw let alone 8. The low end thermostat works brilliantly though. I use it to keep the chill and moisture out the work van. Heating the space though it'd be working hard to do that. Early days see how long this lasts.

I've just talked and 8k heater out due to damage but this one is not hot at all. It's lukewarm and takes the chill off, but would not recommend this one. The previous one you could not put your hand in front of
