The Heat King HK300 is a towable hydronic heater for ground thawing, concrete curing and temporary heat with compatible heat exchangers. BCI Rentals is preparing to offer the HK300 in Backus, Minnesota. It is available soon: call (218) 947-3353 to discuss your project and reserve ahead.
A Heat King heater warms a glycol-based fluid and circulates it through field hoses. Lay those hoses over prepared ground for thawing or use the approved arrangement for concrete temperature protection. Compatible air heat exchangers let a hydronic heater transfer heat into an enclosure without putting the burner's exhaust into that heated air.
| Application or feature | Manufacturer rating | Planning consideration |
|---|---|---|
| Ground thawing | Up to 5,600 sq ft | Soil, frost depth, hose spacing and insulation affect results |
| Concrete curing | Up to 11,200 sq ft | Use the concrete protection plan and required temperature monitoring |
| Temporary air heat | Up to 12,000 sq ft | Depends on insulation, weather and compatible heat exchangers |
| Field hose | Four 700-ft hoses, 2,800 ft total | Plan hose routing and the area layout |
| Heat input class | About 300,000 BTU/hr | Exact input and site requirements depend on configuration |
These are published equipment ratings, not a promised coverage area or thawing time. BCI will confirm the configuration, power, fuel and accessories before a reservation is finalized.
Measure the area and estimate the frost depth before choosing a heater. The hose layout and insulation over the hoses help determine how effectively heat reaches the ground. See our ground heater rental guide for current fleet options and sizing questions.
Hydronic heat and insulated curing blankets can be part of a cold-weather concrete plan. Specify the protection temperature and monitoring method with the concrete professional responsible for the pour.
Ask about compatible heat exchangers when the job calls for air heat from a hydronic system. If ducted warm air is the better fit, compare indirect fired heaters and the other choices in our temporary heat guide.
