Toolbox type deisel heater
This heater was bought to heat a large garage it works very well heats up fast and with no pump noise very good on fuel This is the second diesel heater that I have bought and this is far the best in quality and ease of use

Fantastic Heater
This product is amazing. I have it outside in a waterproof box and plumbed into my front room via an existing air vent using an 8 foot hose. It very quickly warms up the space saving me having to heat the whole house. I am over the moon with this purchase and the excellent customer service I have received. I cannot recommend this product highly enough and my only regret is not buying this sooner. I raised a concern about the pump not being as quiet as I'd expected and a replacement pump was sent out immediately. 5 stars all round

Not reliable at all
This diesel heater is advertised as one of the best out there however they don't tell you it will fail daily- numerous issues with glow plug heating and fuel issue yet using top quality diesel and a 240 input to avoid any issues with battery voltages etc in van I don't recommend buying this as I've emailed but had no further support or refund as requested

I bought this heater because my partner's idea of "roughing it" involves anything under 20 degrees Celsius. Let me tell you, this 8KW beast doesn't just heat a tent; it basically attempts to recreate the surface of the sun in your campsite

Still waiting to be impressed
Dose not perform noticeably better than two other diesel heaters I own which cost less than half the price of this product. It has 10 heat settings, number1 giving out less heat than number1 on the 6 heat setting models, I assume that the pump Hz setting is a lower value which allows the 50 plus-hour run time on low to be made as it it uses less fuel but gives out less heat therefore it is not a true comparison, that and the 6 litre tank compared to 5 litre. Also using the supplied controller as reference it it gives out no more heat than my other heaters. Be aware that nowhere in the supplied manual or on the box does it say it is a 8kw heater only the Amazon listing says that. At the moment it is out of action as it is smelling of diesel in the room the air is being pumped into and I need to investigate why. In conclusion I think this product is more of a marketing exercise than possessing any meaningful improvements over other similar cheaper products.

A veratile heat source.
I love this machine, it operates well and is so easy to use. Operation can be as easy or sophisticated as you choose, it springs into life without hesitation.

I bought this to install in my side by side and has worked better than expected! This unit looks great and at home mounted in the machine. The TB2 is a good value and well worth the money! It has not failed to keep up when riding and bouncing down trails and it keeps you warm! I highly recommend this unit. The hardest part of the installation was figuring out how to mount it in my side by side. As for noise the unit is very quiet and is barely audible even with the side byfunctions. I will try to add video of the unit functiong.

I would give zero stars but not a choice. Item arrived and looked nice. Installed items as shown and added fuel. Primed per directions and then started up. Machine smoked like crazy and never FIRED up. Probably used 1/3 of tank at start up. Drained fuel out exhaust and tried again later with zero luck. It just throws a E10 code and shuts down. Manufacturer suggested checking glow plug. Let me say that pulling machine apart to do that sucks. Glow plug worked as should and cha,her was very wet with diesel in it. Cleaned and put back together. E10 once again. This sucks. Manufacturer saying they are checking to see if they can send me another mother board and glow plug. I will amend if that fixes with 3 stars. I will have three hours in taking apart and putting back together after that. Not happy. Update to previous 1 star. HCalory really stand by their products. They have been working with me to try and figure out the issue but also shipped a replacement unit in case they and I can’t figure out issue. That is service and will gladly buy from them again.

Received it with no issues. Excitedly set it up and after following the instructions for priming, it fired right up. It was quieter than what I hoped for and the pump noise everyone talks about was pretty much nonexistent. Within no time, it started heating my tent up and I was looking forward to using it while camping during the upcoming cold front. And then.... I received an E08 error and was never able to get it to run again. Each attempt ended with the same error code with the occasional E10 popping up. To top it off, after putting it up and returning it to the next day I found that the fuel had leaked out of the heater and now covered by garage floor.

I bought one of these heaters, added fuel after setup, and ran for 30 minutes to test. No problems, but two weeks later to use when I needed the unit to work, unit ran for 2 minutes and it failed to restart, and still won't start after several tries. I bought a second unit thinking I just might have bought a lemon, but it failed also after 30 minute. Link for product support on product page doesn't work at all. 2 pieces of crap.
