Why Vvkb?

When you buy a Vvkb heater, you're buying direct from the manufacturer — not a reseller, not a drop-shipper. That means lower prices, real technical support, and a team that actually built what you're running in your truck or RV.

Certification is granted per model, by a national authority — not to a whole catalogue. Our 2.5KW Apollo-V1 diesel air heater holds ECE type approval under UN Regulation 122 (E24*122R00/06*0054*00) and UN Regulation 10 (E24*10R06/02*4825*00), both issued by NSAI, the National Standards Authority of Ireland, and both covering 12V and 24V. Our diesel air heaters carry CE, RoHS and FCC. Our Titan engine heaters carry CE and RoHS and were EMC tested by TÜV Rheinland. Tell us the model you need and we will send you the exact documents we hold for it.

Thirty years of cold-weather engineering, since 1996. Your questions answered by email, usually the same working day.

With Built-in Pump

The new Titan circulates coolant automatically — no manual bleeding, no external pump to buy or install.

Built-in Thermostat

The thermostat cuts power when your coolant reaches the target temperature. You don't have to remember to unplug it.

Plug-and-Play Installation

Connects to your coolant hose in under an hour. The old design required custom fittings and a mechanic.
