Deciding on whether to replace your traditional hot water tank with a modern on demand water heater can seem complicated.

To help you out, here are 5 of the most common questions we get about tankless water heaters:

Traditional storage tank water heaters heat and store a large quantity of water in a big tank until you’re ready to use it. As the heated water in the tank is used up, more water is introduced where it’s heated and kept at its set temperature on standby until it’s needed.

Tankless systems, on the other hand, heat water on demand using a heat exchanger. Activated when you turn on your shower, washing machine, dishwasher or faucet, the tankless water heater efficiently heats cold water to a set temperature. Water is heated as it passes through the coils and exits from the hot water outlet pipe to where it’s needed in your kitchen, bathroom or laundry room.

Once hot water is no longer needed, cold water stops entering the tankless water heater and the appliance turns off until it’s signaled to turn back on.

If you don’t have natural gas in your home, a propane-powered model could be a great option for you.
