Natural Gas for Residential Temporary Heat (Construction/Finishing Heat)

**IMPORTANT** Information about Temporary Heat


The Enbridge “Residential Construction Heat” program will now be referred to as “Residential Temporary Heat”. Temporary Heat will include options to request activation of: portable construction heaters, furnaces approved for temporary heat (premises under construction), and furnaces used for “Finishing Heat”.Only Enbridge or its authorized contractors will have authority to activate an Enbridge meter for temporary heat or any other purpose. As a condition of using natural gas for temporary heat, builders are required to follow the policies and guidelines for Using Natural Gas for Temporary Heat. Further, builders must send Enbridge an Inspection Request before the new homeowner occupies the property.

If you need heat at your construction site, we can help. Whether you use a portable heater, an approved furnace for construction  heat, or furnaces used for finishing heat, natural gas is an efficient cost-effective choice.

Arrange with joint utility construction beforehand to have your services installed. Once the natural gas appliances have been installed, contact us for an inspection.

Plan for Natural Gas Heating

Effective May 1, 2017 – Manufacturer members of the HRAI have prohibited use of certain furnace models being used for construction heat, which applies to furnace models manufactured after May 1st

For further information, please see our “Frequently Asked Questions”, and “Site Preparation” documents which can be located at www.buildwithgas.com

Whether you're using a furnace or renting a portable heater, your site must meet the following requirements:

  • The building's foundation must be poured and capped.
  • Compacted soil must be within 150 mm (6 in) of the final grade.
  • The site must be clear of obstructions.
  • The meter's final location and position must be clearly marked. (Remember to account for fireplaces and windows when marking a meter's location).

Safety and Training Information

If you are installing or operating a residential gas-fired portable heater, you must have a Record of Training (ROT) certification or have at least a G2 license before the system can be activated. Enbridge will activate the gas service for you - as an ROT holder you will still be required to operate the portable heater.

Your ROT certificate must be presented when your rental company delivers portable heaters to your site and the ROT certificate must be on hand during all work.

Builders, employees and contractors can get certified in a class or on-site. Your local rental company will have more information. 

Your ROT certification is valid for three years and must then be updated.

Customer Testimonials

Using natural gas construction heaters on our job sites has been very convenient. We enjoy a continuous supply of gas, without worrying about switching tanks. And we've experienced few equipment breakdowns. Also, natural gas construction heaters are safe and more cost-effective than propane.

Dominic Di Genova, Contracts Manager, Cachet Estate Homes


When it comes to building a home, we need a safe, cost-effective and reliable source of heat on the job site. Our solution is natural gas construction heaters. They do a fantastic job, and they are cleaner and quiet compared to other temporary heating systems.

Brian McEnaney, VP Construction, Mattamy Homes


I like using natural gas construction heaters—not only are they safer, but they are easy to operate and maintain. I avoid using heaters with an open flame for insurance reasons. These units provide a dry heat that is effective in removing frost from the ground.

Anthony Continelli, Premium Building Group (PBG)
