Types of heaters we rent

Not sure which one you need? The right temporary heater depends on your site, climate, power source and moisture levels. Our team will recommend one when you call.

Electric Heater Rentals

• Flameless, 100% clean heat that adds no moisture
• Easy to install and, in most cases, easy to move
• 5,000 to 200,000 BTU, from 10 kW to 60 kW

Direct-Fired Heater Rentals

• Converts nearly 100% of the fuel source to usable heat
• Runs on propane, natural gas or diesel, with built-in thermostats
• For warehouses, construction sites, tents, mechanic shops and industrial spaces
• UL and/or CSA rated

Indirect-Fired Heater Rentals

• The choice for tightly sealed, enclosed spaces
• Adds no moisture or CO: fresh, clean, dry air only
• The unit sits outside and the heat is ducted in
• Ductwork and corded thermostats are included with most units, and most are on wheels

Construction Heater Rentals

• Converts nearly 100% of the fuel source to usable heat
• Runs on 110V electric power using propane, natural gas or diesel
• Other power options: 240V 1Ph, 220V 3Ph and 480V 3Ph
• Holds about 50°F for drywall, paint, adhesives and finish work

Where our temporary heating is used

• Construction sites and enclosures: keep drywall, paint, adhesive and finish work on schedule through the winter. See our guide to temporary heating for construction.
• Wet or flooded job sites: pair a construction heater with a commercial dehumidifier to dry the space so work can proceed.
• Warehouses, mechanic shops and industrial spaces: high-output direct-fired heat for large areas.

• Vacant commercial properties: electric heaters keep the space above 38°F so wet sprinkler pipes don’t freeze. Read about heating vacant commercial properties.
• Restaurants and occupied buildings during HVAC outages: we delivered and set up electric heaters for two Bob Evans restaurants in Bel Air, MD and Mt. Laurel, NJ during rooftop unit failures.
• Offices, assisted living facilities, tents and events: clean, dry indirect-fired heat.

Heater Rental FAQ

What types of temporary heaters do you rent?

We rent electric, direct-fired, indirect-fired and construction heaters. They run on diesel, propane, natural gas or electric power.

Which heater should I use in a sealed, enclosed space?

Indirect-fired heaters are the only choice for a tightly sealed space with no windows or doors open to fresh air. The combustion by-products are forced outside and only fresh, clean, dry air comes out of the vents.

What size are your electric heaters, and what power do they need?

Our electric heater rentals range from 5,000 to 200,000 BTU, from 10 kW to 60 kW. Some electric heat needs access to higher-voltage, high-amperage power. Construction heaters run on 110V electric power using propane, natural gas or diesel, and 240V 1Ph, 220V 3Ph and 480V 3Ph options are also available.

Do you deliver, set up and supply fuel?

Yes. We provide full-service installation and start-up consulting, propane and diesel fuel delivery and set up, fuel container rentals, free equipment maintenance while on site, and daily, weekly or monthly monitoring if needed.
