Like oxygen, hot water is something you only appreciate when it's absent. So, it's not surprising that a water heater is a vital part of the home. Since each home has its own hot water needs, understanding the various types of heaters and what they offer will help you make the right choice for your family.

Choosing the best high-efficiency water heater

A typical hot water heater accounts for about one-fifth of the energy used in most Canadian homes.

Choosing the right hot water heater, therefore, can have a huge impact both financially and environmentally – especially as energy prices and carbon levies continue to rise.

Many of us still choose conventional, gas-fired hot water tanks because they're cheapest – but are they really? The initial price of your hot water heater can represent as little as 12 per cent of the overall cost over its lifespan. The other 88 per cent is energy.
