Garage Kerosene Heater 2 Models, 10–20 kW
A garage is the hardest small space to heat: a big door, a concrete floor, and no insulation worth the name. Electric heat at the kW required usually means a supply upgrade, which is why the two models here are fuel-fired. 2 of our 28 diesel and kerosene models name a garage in their recommended use — the FS10-21A at 10 kW and the FS20-23A at 20 kW, or 34,121 to 68,243 BTU/h.
Both are direct fired, so both need ventilation — that is the trade for getting a cold space warm in minutes rather than hours. The difference is control: 1 of the 2 carries thermostat control, which lets the burner pause rather than cycling the whole unit on and off. That is the model to specify if the garage is used as a workshop rather than as storage.
Both share the category build: a 441-grade stainless steel combustion chamber rated to 1000°C, overheat cut-off, heat-dissipation protection, flameout protection, shutdown protection and an error indicator light, and an electrical load covering only the fan motor, ignition and fuel pump. Every model on this page is built for diesel or kerosene only — no model here is approved for petrol or bio-oil.

Garage Kerosene Heaters — Full Specification
Heat output as published on each model’s own specification sheet. The BTU/h column is the kilowatt figure converted at 1 kW = 3,412.14 BTU/h — it is a conversion, not a second rating.
What a Garage Kerosene Heater Is Specified For
The question is whether the garage is storage or a place someone works.
Single bay and domestic garages
The FS10-21A at 10 kW is the unit for one bay. It is also the model specified for market stalls and single-room site huts.
Workshops and small construction sites
The FS20-23A at 20 kW steps up when one bay is not enough, and it is the model in this pair that carries thermostat control.
Intermittent use
Fuel-fired heat reaches working temperature in minutes, which suits a space that is cold when you arrive and empty when you leave.

Garage Kerosene Heaters — Common Questions
What size heater do I need for a garage?
The FS10-21A at 10 kW covers a single bay; the FS20-23A at 20 kW covers a small workshop or site. An uninsulated space with a big door needs the higher figure.
Do I need ventilation?
Yes. Both models on this page are direct fired, so combustion products enter the air stream. That is why they are used in garages and ventilated workshops rather than in living spaces.
Which of these has a thermostat?
1 of the 2 — the FS20-23A. See the kerosene heater with thermostat page for the full group.
Can it run on kerosene as well as diesel?
Yes, both models. Petrol and bio-oil are excluded on every specification sheet in this category.
How many BTU is it?
34,121 to 68,243 BTU/h across these 2 models, converted from the published kW ratings at 1 kW = 3,412.14 BTU/h.
Is there a bigger model if this is not enough?
Yes — the full range runs to 190 kW. Start with the kerosene diesel heater range to see every output step.
