Water heating is important, and not just because it feels good to step into a hot shower. Water heating is the third-largest energy expense in most households, coming in just behind heating and cooling. A little knowledge about water heaters can go a long way toward protecting you from losing your hot water or paying more than necessary for this necessity.

What’s new with water heaters? PLENTY!

Most homes in the U.S. have tank-type water heaters. These units use electricity, fuel oil, natural gas or propane fuel to heat the water stored in the tank. Thanks to the ENERGY STAR® program and to our increasing awareness of energy and environmental issues, many improvements have been made in water-heating technology. Here’s a brief summary:

tank-type water heaters

Oil-fired tank-type water heater

More efficient tank-type water heaters. 

The weak point with tank-type water heaters (regardless of energy source) has always been standby heat loss.

When the hot water stored in the tank cools, energy is required to bring water temperature back within the 120-140 degree range.This cooling and reheating cycle goes on continuously, whether hot water is being used or not.

To reduce standby heat loss and make tank-type water heaters more efficient, today’s ENERGY STAR® models are equipped with extra tank insulation.

Tankless water heaters

Gas-fired tankless water heater

Tankless water heaters.

Also known as “demand” water heaters, these units never waste energy because of standby heat loss. Instead, the heating element is activated only when a hot water tap or washing machine is turned on.

Most tankless water heaters burn natural gas or propane fuel, and are small enough (about the size of a suitcase) to be mounted on the wall, taking up very little space.

Depending on water usage habits, replacing a tank-type water heater with a tankless model can cut your water-heating expenses by as much as 40%.

But it’s important to note that a tankless water heater can cost twice as much to install as a new tank-type heater.

Heat pump water heaters

Heat pump water heater

Heat pump water heaters.

This tank-type water heater relies on a small, electrically powered heat pump instead of an electric resistance heating element.

A heat pump water heater can be twice as efficient as standard electric tank-type water heater, making it a smart upgrade if you need to replace an old tank-type water heater.

Indirect water heaters.

With an indirect water heating system, your whole-house boiler, furnace or heat pump does double duty. In addition to keeping your home warm, this HVAC equipment also heats the water you use for washing. In other words, you don’t need a separate water heater. During winter months when your HVAC system is supplying heat to the house, you get your hot water for free.

Solar water heating.

Solar thermal systems have been in use for many years. Today’s systems are reliable and can cut water heating costs by around 80%. Any solar thermal system will require some sort of backup water heater to take over when the sun isn’t shining.

Nick Nason completed an insulation evaluation and upgrade at our condo last winter. As a result of his excellent work our heating costs so far this winter are 50% of what they were last winter at this time, despite much colder conditions. In addition to the financial savings the level of comfort has improved tremendously.
