Before Ordering
What is a flameless mobile heater?
It uses an engine-driven hydraulic heat loop rather than an open flame at the heating unit, subject to the manufacturer's operating requirements.
What is an indirect-fired heater?
Combustion occurs in a heat exchanger so heated supply air is separated from the combustion stream and can be ducted to the work area.
How should BTU capacity be selected?
Required output depends on space volume, insulation, air leakage, outdoor temperature, target temperature and duct losses.
What details are needed for a heater quote?
Provide the site dimensions, temperature conditions, desired model or BTU class, ducting, fuel, runtime, restrictions, quantity and delivery location.
