AUTOTERM Flow 14TC-Mini (Flow 14D) — 14.5kW Diesel Water Heater
This is the big gun of diesel hydronic heating. The Autoterm Flow 14TC-Mini (now officially called the Flow 14D) pumps out 14.5kW of heat — enough to pre-heat a large truck engine, warm a full-size motorhome, or heat up a hydronic system holding up to 70 litres. It runs independently from the engine, so it's doing its job before you even turn the key.
If you're building on a larger platform — a big truck, a coach conversion, or a commercial vehicle — and you need serious, reliable heat without draining your battery, this is the heater for the job.
Important: Please contact us before ordering to confirm this heater is right for your installation. Some newer vehicles may require a third-party EPCU module for cabin heating integration.
