What Is a Combi Boiler?

A combi boiler, short for combination boiler, is a versatile heating system that combines the functionalities of a boiler and a hot water heater into one compact unit. Combi boilers provide central heating by circulating hot water through pipes in your home. They keep you and your home cozy during our chilly Edmonton winters. Plus, they also act as your water heater so there’s no need for a separate Hot Water Tank.

Why Choose a Combi Boiler?

  1. Space-Saving: Combi boilers eliminate the need for separate heating and water heating units. They’re perfect for any home but especially homes where space is precious. Plus, they’re great for retrofit applications where two water heaters were needed previously.
  2. Efficiency: Combi boilers heat water on demand, avoiding energy wastage from storing hot water in a tank. Their high efficiency translates to lower operating costs and a lower energy bill for you. Payback can occur in just 3 years due to energy efficiency increases from 50% on your old water heater to 96% with your new combi boiler.
  3. Seamless Switching: Combi boilers seamlessly switch between space heating and water heating, ensuring you have hot water whenever you need it.
  4. Upgraded Warranty: Warranties are twice that of conventional hot water tanks. Most combi boiler units have a 12 year warranty so you can rest assured these units will last.
