10 Heating and Insulation Tips for an Energy-Efficient Home

In most cases it is not the type of heating that matters most for energy efficiency, but how well the home retains its heat. Here are a few simple tips that could save you hundreds of dollars a year in energy costs.

Install Programmable or Smart Thermostats

A programmable or smart thermostats helps reduce energy costs by allowing the user to set the temperature depending on family needs or the time of day.

  • For example, the thermostat can be set to lower the temperature automatically during the day while everyone is out and raise it again in the evening.
  • Set it to lower the temperature at night and raise it to a comfortable level in the morning. Air conditioning systems can also be pre-programmed in the same way. 

Add Insulation in the Attic

Most attics are insulated, but adding more insulation will dramatically reduce energy costs.

This is because heat rises. If the ceiling is cold due to insufficient insulation then the furnace will have to work harder to maintain the desired temperature.

  • In colder areas of the country, it is recommended to use insulation with an R-value (a material's ability to resist heat flow) of R40 to R50 (13 ½" to 16 ¾" of fibreglass blanket insulation).
  • Additional insulation will also help reduce air conditioning costs in the summer.

Plant Trees for Sun Protection

Trees provide welcome shade outdoors during hot summer days!

  • Trees can also keep the inside of the home cool by blocking the sun's hot rays.
  • In the winter, they provide a barrier against cold winds. 

Install a Ceiling Fan

Inside, heated air rises and accumulates at ceiling level, cooling the rest of the room down. In the winter, it takes time and energy to keep the whole house warm.

To solve this problem:

  • Install a ceiling fan to push warm air down and spread it evenly throughout the home.
  • The central heating system won’t have to work as hard to maintain the same temperature. 

Install an Insulation Blanket for your Water Heater

All hot water tanks are lined with special insulating foam, but heat can still escape from other parts of the tank.

To solve this problem:

  • Installing an insulation blanket is inexpensive and keeps the tank warm. The heating element inside will consume less energy to heat the same amount of water, reducing the energy bill.
  • The pipes leading out of the tank can also be covered with pipe insulating foam.

Caulk around Windows and Doorframes

Check for drafts around doors, windows, or electrical outlets with a special wick that gives off a small amount of smoke when lit.

If the smoke blows horizontally, there is a draft.

Seal any gaps with a durable acrylic caulking product.


Seal Air Ducts

Seal heating ducts with metallic duct tape to prevent heat (or, in the case of air conditioning, cool air) from escaping through cracks and joints.


Replace Furnace Filters

Air inside the home can contain dust particles that may cause discomfort to occupants. These particles can cause the furnace or air conditioner to work harder to maintain the desired temperature and even decrease the life of fan motors by getting into the moving parts.

To solve this problem:

  • Change the disposable filters in your heating or air conditioning system


  • Clean permanent filters twice a year.

Install Window Insulation Film

Window film is inexpensive and significantly improves thermal insulation in your home.

Even the best double-paned windows with a low-emissivity coating and argon gas-filled spaces only have an R-value (a measure of energy efficiency) up to R3 or R4.


Seal Electrical Outlets

Many homes built prior to 2000 were made without a barrier inside the walls to keep wind from getting in through outlets in exterior-facing walls.

Cold air can get past wood or vinyl siding, form channels in the fibreglass batts and then find its way into the home through interior light switches and outlet boxes.

To solve this problem:

  • Install vapour barriers over your electrical boxes to keep out cold air.
  • You can also install socket covers
