4kw heater Phenomenal little heater. Better than espar, webasto, etc. highly recommend. Operation is simple and easy. Dropping the gas tank is tricky, and removing the fuel pump apparatus is also a bit of work. But it’s worth knowing this thing won’t crap out mid-winter. Highly recommended. Was able to fit this under the passenger seat of a 2023 transit, and I was able to rotate the inverter so inverter also fits

NOTE WELL the return policy!! The builder's opinion is that the unit is too heavy for the roof of my particular van. That is not Velit's fault. What I did not expect was the only return within 30 days if it does not work return policy. I did not even think to check the policy because...well, who doesn't have a 30 day return policy for an unopened box? I take responsibility for not checking, but I find this policy completely unreasonable. Now I have a $1700 (including shipping) unit that I cannot use.

Good product and solid customer… Good product and solid customer support. Our 2000R unit worked great on four 100ah lithium batteries. Install was a bit tricky, but got good answers from the support guy. Looking forward to the housing extension for thicker roof installations.

This is a first rate company. Everything from ordering to delivery was great. I had one question about items packed and I got a response right away (I'd misplaced the gasket as it turns out). I'm still in the midst of installation.

Diesel Heater Upgrade I just replaced my diesel heater with the Velit Gasoline Heater, it is definitely an upgrade. I no longer have to carry diesel and the fuel pump tick is not noticeable. I also tested the temperature control that shuts off the heater at 3 degrees past the set point and starts again at 3 degrees below the set point. I would recommend this heater for any RV that runs on gasoline.
