Diesel & Engine Block Heaters — Engineered Since 1996
Diesel Heaters & Engine Block Heaters — Direct from the Manufacturer
You get a heater that actually works at -40°F/-40°C — tested and certified, not just labeled that way. Every unit leaves our factory CE and RoHS certified, and the Apollo-V1 carries ECE R122 and R10 type approval on top, so you know exactly what you’re buying.
You’re buying direct from a manufacturer with 30 years of production experience and our own tooling — not a middleman. Whether you need one unit or a full container, you get factory pricing and the same certified product.
ECE Type Approval — R122 & R10 (Apollo-V1)
The Apollo-V1 carries ECE type approval under both R122 and R10 — approval numbers E24*122R00/06*0054*00 and E24*10R06/02*4825*00, issued by NSAI, the National Standards Authority of Ireland, under UN regulations. Type approval is required for heaters fitted to vehicles used on European roads.

FAQ
A diesel air heater burns a small amount of diesel in a sealed combustion chamber, then blows your cabin air across a heat exchanger — so no exhaust ever mixes with the air you breathe. Vvkb diesel air heaters come in 2.5 kW (Apollo-V1) and 5 kW (Apollo-V2) and work down to -40°F (-40°C). Fuel use stays low, around 0.14–0.25 L (about 0.04–0.07 gallon) per hour depending on heat level.
Yes — the combustion chamber is sealed from your cabin air, and exhaust exits outside the vehicle. Our Apollo-V1 holds ECE R122 and R10 type approval (E24*122R00/06*0054*00), which requires independent safety testing. Fit a carbon monoxide detector anyway — it is cheap insurance and standard practice among van and boat owners.
Most $100–200 diesel heaters are unbranded units with inconsistent quality control — the common forum complaints are fuel-pump failures, carbon build-up, and weak controllers and wiring. Vvkb designs and builds its own heaters, backed by CE certification, ECE R122 type approval on the Apollo-V1, a 1-year warranty, full spare-parts supply, and direct technical support. You are buying from a manufacturer with 30 years of production, not a rebranded batch you replace next winter.
A 2.5 KW–5 KW diesel air heater pulls about 10 amps for the first minute at startup, then settles to roughly 1–2 amps once it is running. Overnight that is about 10–20 Ah, depending on how cold it is and how often the heater cycles. Use a deep-cycle or lithium leisure battery — a starter battery handles a single night but wears out fast under repeated use.
A diesel air heater warms cabin air directly — best for trucks, vans, and RVs. A diesel water heater heats coolant, which can pre-warm your engine, supply hot water, or feed underfloor heating. Choose air for fast cabin heat, water for engine pre-heating and multi-use systems.
An engine block heater pre-warms your engine coolant on 110V/230V shore power so it starts reliably in deep cold. Most drivers plug in a diesel around 32°F (0°C) and a gas engine around 0–10°F (-18 to -12°C); below -20°F (-29°C) it is close to essential. Put it on a timer 2–3 hours before you drive — it cuts cold-start wear and improves fuel economy on the first miles. (A block heater warms coolant, not fuel — for fuel gelling you need a separate fuel heater.)
Tell us your cabin size (or coolant volume) and your coldest expected temperature, and we will point you to the right model. You can also use our heater application guide, which sorts heaters by vehicle and use.
