175,000 BTU Kerosene Heater 5 Models at 50 kW
A search for a 175,000 BTU kerosene heater is a search for roughly 51.3 kW of output. Heaters are not built to arbitrary BTU figures — they are built to output steps — and the step we build nearest to this one is 50 kW, which is 170,607 BTU/h, 2.5% under the figure searched. There are 5 models at that step.
The 5 models split by firing type. 3 are direct fired — the open flame heats the air stream and a fan delivers it, which is the choice for workshops, factory floors, hangars, warehouse aisles and outdoor assembly areas. 2 are indirect fired, where the flame heats a heat exchanger and the flue gases are ducted away; those are the ones specified for dust-sensitive processes, coating lines, painting and coating booths and food preparation halls.
All 5 share the category build: 441-grade stainless steel combustion chamber rated to 1000°C, overheat cut-off, heat-dissipation protection, flameout protection, shutdown protection and error indicator light, and an electrical load limited to 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.
The 50 kW Step at a Glance
175,000 BTU/h is about 51.3 kW. The nearest output step we build is 50 kW, which is 170,607 BTU/h — 2.5% under the figure searched. BTU/h is converted at 1 kW = 3,412.14 BTU/h.

Output Steps on This Page
All 5 models on this page sit at the same output step, so the choice is firing type and application rather than output.
What a 50 kW Diesel or Kerosene Heater Is Specified For
Around 170,607 BTU/h is a large-workshop output, not a room output.
Large workshops and factory floors
The direct-fired models at this step are specified for large workshops, factory floors and hangars.
Warehouse aisles and logistics halls
High-volume spaces heated by air movement. One model at this step names warehouse aisles, logistics hubs and storage halls.
Coating lines and food preparation halls
The 2 indirect-fired models at this step are the ones to specify when the air has to stay clean.

Each specification below opens the models in production for it, with heat output, firing type and recommended application.
175,000 BTU Kerosene Heaters — Common Questions
Do you make exactly 175,000 BTU?
No. Output is stepped, and the step nearest to 175,000 BTU/h (51.3 kW) is 50 kW, which is 170,607 BTU/h — 2.5% under. We list that honestly rather than re-badging a lower rating.
How many models are at this step?
5: 3 direct fired and 2 indirect fired.
What is 175,000 BTU in kW?
About 51.3 kW at 1 kW = 3,412.14 BTU/h. The nearest step we build is 50 kW.
Direct or indirect at 50 kW?
3 of the 5 are direct fired and 2 are indirect. Pick indirect if people occupy the space all day or if there is dust, coating or food in the air.
Will it run on kerosene?
Yes — diesel or kerosene only, on all 5 models. Petrol and bio-oil are excluded on every specification sheet in this category.
Is there a higher step if this is not enough?
Yes. The next step up is 60 kW — see the 220,000 BTU kerosene heater page. The range runs to 190 kW.
