Did you know that space heating can represent up to 63% of a home’s energy use, according to Natural Resources Canada? That means choosing the right furnace or boiler can make a real difference to the cost of heating your home.

Here’s a quick comparison:

Heating and Combi Boiler

  • May not be suitable for all homes, depending on the architecture. (Ask you Home Comfort Advisor if you’re unsure.)
  • Keeps your house warm by pumping heated water to radiators and other radiant heating devices.
  • A Heating and Combi Boiler system provides heat as well as a steady supply of hot water.
  • Can be a great choice for homeowners interested in upgrades like in-floor heating, heated driveways, and hydronic towel racks.
  • Can even be used to keep your pool or spa water warm.

Energy-Efficient Furnace

  • Keeps your house warm by pumping heated air to air vents.
  • Today’s energy efficient furnaces have AFUE ratings of between 92% and 98%, which is a considerable increase over older models.
  • When you choose an ENERGY STAR certified, forced-air, gas-fueled furnace it will use 6% less energy on average than a standard model.

Your Home Heating Advisor is here to help you select the best heating solution for your home. We’ll even let you know about any government rebates and other incentives available for residents of St. Catherines that may help you lower the cost of your new system.

Your furnace installation should always be left to a professional. A poorly-installed system may not work efficiently, and could even pose a safety risk.

When you call on Reliance™, you can rest assured that the installation of your new system will be completed by a team of licensed HVAC technicians who abide by our Technician Code of Conduct.

We’ll deliver, install, and test your furnace. We’ll even clean up before we go! And our customer service doesn’t end there. If you’re not 100% satisfied with the performance of your new home heating system, we’ll return to address and resolve any issues.

You can help installation day run smoothly by decluttering your furnace room, keeping pets and children away from the workspace, and having your WiFi password handy.

Then, you’ll just have to relax in comfort and enjoy everything winter in St. Catherines has to offer!

  • How do you currently heat your home?
  • Are you interested in added luxuries like in-floor heating?
  • Is energy-conservation a top priority?
  • Do you prefer to rent or buy your home heating equipment?

Renting vs. buying a furnace

When it comes to the decision to rent or buy, there is no one-size-fits-all solution. The right answer depends on many things, including the type of equipment you choose, your lifestyle, and your budget.

Here’s what you need to know:

If you buy, you’ll pay for your system upfront and will be responsible for the cost of maintenance and repairs once your equipment warranty expires. Owning your unit may add value to your home, and a Protection Plan from Reliance™ can protect your monthly budget from unexpected repair bills.

If you rent, you’ll be responsible for an affordable, monthly payment. Your rental fee covers maintenance and most repairs, as well as an annual inspection, furnace filters, and humidifier pads.

Still not sure whether it makes more sense to rent or buy? Read more about buying vs. renting.
