If you're in the market for a new hot water heater, you may be unaware of the options available to you. Here's a list of types of hot water heaters to consider, and some alternatives.
Tips for choosing a hot water solution
- Think about how much capacity you need. If the number of people in your household has gone up or down, or if your water use has decreased in general, maybe it's time to look at something with larger or smaller capacity.
- Go with what's already there. It will be easier and less costly to go with a new natural gas furnace if your old one ran on gas too. Same with electric. Tankless water heaters are easier replacements for electric tanks.
Types of tanks
Atmospherically vented – The oldest type, not much available anymore. Hot gases from the burner rose past the tank, heating the water, and then up through a flue to the outside. Not very energy efficient, but still works in a power outage.
Power vented - Instead of the gases naturally rising into the flue, a fan pulls the gases out of the tank and into the outdoors.
Sealed combustion - A power vented tank with an additional inlet pipe that comes from outside and supplies air to the burner. This isolates the combustion part of the heating completely from the air inside of the house.
Condensing tanks - These are sealed combustion tanks that use technology advances to squeeze more efficiency out of the burner's heat, directing more of it to actually heating the water.
Tankless - not really a tank, these are very popular in Europe where space and fuel are at a premium. The water isn't kept hot in a tank all the time; the heater kicks in when the tap turns on, heating a long series of pipes that the water flows through and heats up.
