Trusted, High-Quality Brands
At National Heater Shops, we stock heaters from dependable and well-known manufacturers, including Master, Arcotherm and Thermobile.
Our marquee heaters vary in size, power source and energy supply, with outdoor models available that run on diesel, kerosene or paraffin. Each heater uses an internal fan to draw air in, pass it over a heat exchanger and distribute it without any contact with the flame. This ensures warm, clean air is safely delivered into enclosed areas such as marquees and event tents.
Indirect heaters are positioned outside the marquee, with flexible ducting directing warm air indoors. A thermostat helps maintain a steady temperature, automatically switching the heater on and off as needed. Built to withstand rain, snow and challenging conditions, these robust units provide dependable heating for your event.
