Diesel & Kerosene Heaters
10kW Diesel Forced Air Heater for Small Workshops
Model: FS10-21A
The FS10-21A is a 10kW direct-fired diesel and kerosene heater from our 10kW to 190kW forced-air range. It burns diesel or kerosene in a 441-grade stainless steel combustion chamber rated to 1000°C and blows the heated air straight into the working area through a high-power enclosed fan, so heat arrives within seconds of ignition. Direct-fired units raise the incoming air temperature by 40–60°C and are intended for well-ventilated sites with an air change rate high enough to carry the combustion products away — construction and renovation work, workshops, warehouses, barns, factories, dock yards and rail or road works. Other 10kW direct-fired models sharing this output: FS10-23A. Tell us the destination market and we will confirm the voltage, plug and certification package that goes with this model.
Features
- Compact 10kW unit — the lightest way to heat a one-room workshop or stall
- Runs on the same diesel or kerosene you already keep on site
- 441-grade stainless steel combustion chamber, rated to 1000°C
- Multi safety protection: overheat cut-off, heat-dissipation protection, flameout protection, shutdown protection and error indicator light
- Fuel: diesel or kerosene only — petrol and bio-oil must not be used
10kW Diesel Forced Air Heater for Small Workshops
The FS10-21A is the smallest unit in the FS range at 10 kW, and that is its point: a one-room workshop, a market stall, a garage or a single-site cabin does not need 50 kW of air, and buying it wastes fuel all winter. It burns the diesel or kerosene already kept on site, so no separate fuel supply has to be organised.
Because it is small enough to be carried and light enough to be moved by one person, this diesel forced air heater suits sites where the working area changes day to day — from a bench to a loading bay. The 441-grade stainless steel combustion chamber is rated to 1000 degrees C, which is what keeps the flame-side metal intact across season after season of use. Five protections are built in: overheat cut-off, heat-dissipation protection, flameout protection, shutdown protection and an error indicator light. Fuel must be diesel or kerosene only — petrol and bio-oil must never be used.
FirstSight builds the FS range from 10 kW to 190 kW as a wholesale and OEM line — your voltage and plug standard, your logo, your paint colour and your carton artwork. Direct-fired heaters need well ventilated space, so this model suits trade and industrial buyers rather than domestic retail. Ask for the diesel heater catalogue, certificates and test reports.
