Types of Water Heaters
There are a few types of water heaters for you to choose from:
- Conventional water heaters – the most popular and well-known type of water heater, conventional water heaters have a storage tank in which the heated water is held for usage. The average lifespan of a conventional water heater is 10-15 years.
- Tankless water heaters – tankless water heaters, also known as heat-on-demand, do not use a storage tank to provide your home with water. Instead, when you open your hot water tap on a faucet, your cold water is run through a heat exchanger that quickly heats the water and pushes it through your faucet. Tankless systems have an average lifespan of 20+ years.
- Heat pump water heaters – just as heat pumps for your home transfer heat from one location to another to both heat and cool, so, too, do heat pump water heaters – they just transfer the heat into a storage tank to heat your water. Heat pumps home heating and cooling systems can also heat water, or you can have a stand-alone heat pump water heater. Heat pump water heaters are very energy efficient and have a lifespan of 10-15 years.

Deciding which fuel type to use for your water heater will depend largely on what’s available in your home and your personal preferences.
Properly sizing your water heater requires a small calculation. First, you have to determine your home’s first hour rating, known as FHR. This is the amount of water used during the busiest water-using time of day, such as a weekday morning. To do this, allot 12 gallons of water per person; then add up the number of bedrooms and add 1. Take the number of bedrooms plus 1 and multiply it by the 12 gallons; this gives you your home’s FHR value.
