Frequently Asked Questions

General FAQ
Q: How do I choose what type of heating appliance I want?

A: The type of heating appliance you need depends on the type of fuel you want to burn and the square footage of the area that you need to heat.

Q: What are the different costs involved between fuel types?

A: Your total annual heating cost will depend on the price of fuel, the efficiency of your system and the energy efficiency of your home. Heating a poorly insulated home with an outdated inefficient system that consumes a high priced fuel will cost the most.

Q: How will my insurance be affected if I get a gas or wood appliance?

A: We recommend that you discuss all insurance related questions with your insurance provider. Generally there are no problems with insurance as long as your system is installed according to all applicable codes.. For more information please consult our insurance section.

A: We suggest you check with your local building authority as to whether or not a building permit is required.

Q: Can I buy my appliance online?

A: At this time we do not offer an online shopping service. Online shopping may be offered at a future date.

Q: How do I know what size of insert will fit into my existing fireplace?

A: We have created a form detailing the measurements required to fit an insert into a fireplace. Once the measurements are taken we do a scale drawing of your fireplace and then compile a list of inserts to choose from.

Q: What is a pellet stove?

A: Pellet stoves are heating appliances that are designed to burn pelletized fuels made from wood, corn or other biomass wastes.

Gas Appliance FAQ

A: Most new gas appliances are shipped from the factory setup for natural gas. The licensed gas installer will be able to convert the unit to propane.

Q: Can I install my new gas appliance myself?

A: No, the activation of the appliance must be done by an appropriately licenced technician.

Q: What is the difference between natural vent and direct vent?

Q: Can I clean the inside surface of my gas appliance?

A: Yes, using the appropriate cleaner.

Q: Do I have to have an existing gas line into my house?

Venting / Chimney FAQ

A: In most case no. Wood stove chimney’s must meet the CSA standard S-629.

Q: What is the difference between single and double walled stove pipe?

A: Single wall pipe is a minimum 24 gauge mild steel and requires 18″ clearance to combustible material. Double wall pipe has an interior stainless steel pipe surrounded by heat shield and in most cases requires 6″ clearance to combustibles.

Q: Will my new appliance require a flue pipe damper?

A: No. Combustion is controlled with the air control on the stove. In rare cases with a tall chimney a damper will help slow down the airflow.

Sauna FAQ
Q: What size of electric sauna heater does my sauna room require?

A: For every 50 cubic feet of room space one kilowatt of heating capacity is required.

Q: Should the wood walls in my sauna be unfinished or be sealed?

A: The wood walls should be sealed to prevent water damage. Do not use oil based sealers because as the sauna room heats up off-gasing will occur.

Looking Forward to Using Our New Fireplace!

The guys from Nordic Energy Systems were really good. We called them to install a new fire place/chimney. Going into the project I was a little bit worried. We had a brand new steel roof and I was afraid it might get messed up during the installation, but my fears were unwarranted. Everything looks great!

I can’t say enough about Nordic Energy

I can’t say enough about Nordic Energy. From the choosing of the stove to the explanation of how it works the store staff (Denis) was amazing. Where to start with the installation crew. Lucas (Logan) lol Rob and Jacob. What an awesome crew. Very pleasant and knowledgeable. They took such care with my home and in their detail to the little things. The job was never rushed and was done with care. Everything was explained so that it was clear and questions answered. I cannot say enough about Lucas and how he explained everything to me and how if he didn’t like the way things were working once the stove was set up he went back and made sure it was to his satisfaction. It speaks volumes to see someone take such pride in his work. Thanks so much for the amazing service to you all. I would give an 11 if I could. Will highly recommend your company. I will definitely be back for future business. Thanks so much.


We absolutely love the fireplace!

We wanted to let you know that we have used our fireplace a few times now. There were several evenings earlier in September that were chilly and gave us a good excuse to try it out.

We absolutely love the fireplace! It fits our room perfectly and provides just the right amount of heat. You suggested the perfect model for what we needed and wanted.

Thank you so much for the wonderful service provided by you and your team. We also appreciate your patience with us through the installation process, including the return trip to our house to get the fireplace in the right spot. Your efforts to make everything just perfect were much appreciated. Kind regards

A. Lavoie

A completely great experience every step of the way.

Your installers are superb.
