What to Look For While Renting a Portable Heaters

Portable Heaters

Renting portable heaters to warm an office, retail space, event tent, indoor building, and construction site or manufacturing or industrial facility can be less straightforward than you may think.

“Many people simply think ‘heat,’ and they do not consider all of the elements that might go into sizing a job,” said a popular industrial professional.

Knowing the space you want to warm, the type of heater which may meet your requirements, and the most voltage that your sockets can manage are among the challenges of deciding on the type of portable heater for your job.

Heating needs

What ambient temperatures do you need the space to be, and just how much heat output you need from a portable heater to achieve it?

Several factors figure into answering the second question. They comprise the square footage of your space, the number of windows and doors, the substances of the floor, ceiling, and walls, and the height of the ceiling. “Many individuals don’t take ceiling elevation into consideration — and heat rises,” said a professional.

The degree of insulation matters, too. If you’re heating an outdoor tent, do not treat it as an indoor space of identical size. “Lots of people don’t consider that a tent doesn’t have any insulating material,” said an industry expert. “That’s why you’ll go to a lot of event tents and it will be cold, or hot on the other side of this equation.” Also, think about the number of people that will occupy the space; more individuals generate more heat.

Qualified power and HVAC climate specialists will calculate the heat needs of the space before recommending a temporary heating solution. They will use the insulation factors of the area’s surfaces (walls, ceilings, flooring) and the sizes of these surfaces to figure out the total BTU load, then use the following formula to figure out the BTU/kW of heat required. If you happen to know your total BTU load, then you can figure out approximately how many kW that you need in a heater. Multiply the heater’s wattage by 3.412 for BTU per hour. A 15,000W electric heater produces approximately 51,180 BTU per hour. You can also call professionals from Preferred Climate Solutions to get the perfect and right size electric heater on rental.

Propane, natural gas, and diesel, electric — your choice will be dependent on your needs and your budget. Electric heaters generate clean, dry heat, and they do so quietly. In case the unit will sit indoors, it’s the simplest choice because it generates no exhaust or carbon monoxide.

Combustion-powered units must be utilized outside unless you have a way to extend the flue pipe outside. If placed outside, the heat can then be ducted indoors through a window, door, or another opening.

Budget-wise, electricity usually will not function as the best bet. “Diesel, natural gas and propane will be cheaper to run than electric,”

A heat pump is just another option when you have a way to vent the exhaust.

So far as fueled-fired heaters and the risk of fire goes, indirect-fired heaters, in which the flame is contained in a heat exchanger, are safer, albeit more expensive and less efficient, compared to direct-fired heaters.

Voltage requirements

If you’re looking to rent a heater and all you need to work with regarding power outlets is a conventional 115-volt outlet, electrical will not do the trick unless the space is small or you intend to rent multiple low-wattage heaters. For bigger BTU/kW output, you’ll need natural gas, diesel, or propane heater.

A higher-voltage energy supply, on the other hand, can power the larger electric heaters. If you’re not sure what you have — and a lot of people aren’t — consult your electrician or engineer.

Once you verify that you have the voltage you need for the electrical heater that you want to rent, ensure you have the appropriate breaker to the amperage.

Specifying the most effective temporary heating solution for virtually any job requires a considerable amount of thought.

Choosing a heater that isn’t suitable for your job can leave your workers or customers in the chilly, blow your fuses, or worse. Choosing any appropriate heating solution starts with performing a precise load calculation. “Otherwise you are just throwing a heater in a problem and you do not even know if it’s going to operate.”
