You probably don’t want your customers to slow down just because of a little chill in the air, or even when there’s three feet of snow on the ground – especially when it means you can rent them a portable heater.

You probably don’t want your customers to slow down just because of a little chill in the air, or even when there’s three feet of snow on the ground – especially when it means you can rent them a portable heater.

The heater industry isn’t usually subject to massive revolutions that change everything in the blink of an eye. Instead, the typical way forward is one of slow, incremental progress. This year is no different, with a number of heater companies launching models with improved performance, additional features, or both.

Allmand Bros.

Allmand Bros. has upgraded its Maxi-Heat portable heater with higher static pressure and longer ducting. The static pressure of the Maxi-Heat has increased from 0.5 water gauge wg to 1.5 water gaugewg. This increase in static pressure has allowed Allmand to increase the length of the Maxi-Heat’s 16-inch ducting from 40 feet to 110 feet.

According to Allmand, the new upgrades to Maxi-Heat have increased both the performance and versatility of the portable heating unit. Maxi-Heat features twin heater units that produce a maximum of 1,010,000 British thermal units (BTUs), and may be operated independently, depending on heating requirements. A standard 1,800-revolutions per minute liquid-cooled Isuzu diesel engine with regulated generator provides power for the heaters and electrical accessories. A 191-gallon fuel tank provides more than 24 hours of operation without refueling. 

In addition to the static pressure and ducting upgrades, the company says it has incorporated another important performance feature into the Maxi-Heat. Allmand has also added an in-line fuel heater and pre-filter to the fuel system on the unit. Allmand says this is especially important in situations where fuel may be contaminated or is not blended properly for the operating conditions. The heater/pre-filter makes the system more tolerant to dirt and variances in the viscosity of the fuel, which means improved performance and dependability.


Model 800

DeCloet presents its Model 800 series indirect-fired heater/dryers. According to the company, extensive winter testing has proven that the DeCloet approach to heating and drying is both effective and extremely fuel-efficient. The DeCloet heater/dryers utilize the basic principles of traditional forced air heating with no gimmicks or electronics, which the company says makes the DeCloet heater/dryers as simple to use as a household forced air furnace.  

The DeCloet 800 series heater/dryers are designed to both warm and dry a building space. The DeCloet 800s are available with Tri-Fuel Burners – Fuel Oil, NG or LPG – and provide 800,000 BTU’s of clean hot and dry air at over 11,000 CFM. The units can be used indoors or outdoors, and air can be ducted 100 feet or more into a building or into existing ductwork to supply emergency or temporary heat. The units are capable of recycling from zero to 100 per cent of the air in a building, allowing the user to save up to 40 per cent of fuel costs.

The Model 800 boasts heavy-duty all-stainless steel skins and all-steel construction, with a stainless steel heat exchanger to ensure clean, dry air.

The kerosene line sizes range from 75,000 BTUs/hour to 700,000 BTUs/hour.

Heatstar’s kerosene heaters can actually operate on kerosene, heating oil, or jet fuel. A simple air pressure adjustment on the intake end of the heater allows the operator to fine tune combustion for clean burning, oduor free operation.

The company also offers forced air propane, convection, and portable radiant heaters.

Using the motto “Workin’ Warm, Workin’ Tough,” Heatstar promotes its line as “the toughest portable heater you can buy.”



According to Suncat, the VAL6 can start up or shut off in seconds, and reaches peak efficiency in a couple of minutes. This feature provides more flexibility in application, and achieves high efficiency.

The VAL6 is an infrared heater, rather than forced air. Suncat says this provides several advantages, as it will not lose heat from and cold air when used outdoors. The straightforward infrared heat generated is completely unaffected by air flow, thus creating a quiet and dust-free environment.

The combustion system of the VAL6 produces no odour and no smoke while running. The exhaust gas goes upward.


Sure Flame

Sure Flame heaters are often recognized by their blue colour, but the company says that this model just got greener. Building on the previous successes of the Model IX1500 heater, Sure Flame has announced further enhancements to this 1,500,000 BTU/hour indirect-fired construction heater. With refinements to the burner and heat exchanger, Sure Flame says the 2010 model achieves even greater efficiency, thereby reducing fuel consumption and the amount of carbon being released into the environment.

The burner utilizes UV flame sensing technology for increased reliability in tough construction environments. The heater retains its compact design from previous models. The small footprint means not only that it takes less space on the job site, but it also requires less space for off-season storage. At only 32.5 inches wide, it will fit through most openings. The IX1500 will operate on either natural gas or propane.  Switching fuels is done with a simple turn of a handle. The IX1500 is part of Sure Flame’s line of fifteen models of direct and indirect-fired heaters ranging from 100,000 to 2,250,000 BTUs.
