Why Choose the Planar 4D Over a Cheap Diesel Heater?
There are many inexpensive diesel heaters available today. While some budget heaters can provide good value, the Planar 4D is aimed at customers who place greater importance on the overall heating system, documentation, serviceability and long-term ownership.
More Heating Capacity
The Planar 4D produces up to 4.0 kW / 13,600 BTU/h, giving it substantially more maximum heating output than a typical 2 kW portable heater. This makes the 4D a strong choice when you need to heat a larger space or want additional heating capacity in very cold conditions.
Purpose-Built Portable Design
The heater comes in a crushproof, rain-resistant case, allowing the complete heating system to be transported between your RV, camper, boat, hunting shelter or ice-fishing hut.
Designed for Cold-Weather Applications
The Planar 4D is intended for recreational and outdoor applications where dependable heat is important, including winter camping, RV use and ice fishing. Planar also provides dedicated installation, repair and spare-parts documentation for its heater systems.
Serviceability & Documentation
A major advantage of buying an established heater system is access to technical information and replacement components. Planar provides installation manuals, repair manuals, spare-parts information and controller documentation for its heater products.
