What Are On-Demand Water Heaters?

An on-demand water heater is a type of appliance typically used to provide hot water in households. Also known as tankless or instantaneous water heaters, these appliances heat water as it passes through them rather than heating and storing large amounts of water.

On-demand water heaters typically feature a few key components, such as a control valve, a heat exchanger, and a thermostat. The valve closes when the water pressure is low, which helps to conserve energy. The heat exchanger is the device that heats the water while the thermostat detects the temperature of the water and adjusts it as needed. In this way, the water is always heated only when it is needed.

What Are the Benefits of On-Demand Water Heaters?

On of the most appealing benefits of on-demand water heaters is their energy efficiency; since the water is only heated when it is needed, there is no wasted energy as there is with traditional hot water heaters. Additionally, because these systems heat up water quickly, they provide almost instant hot water to reduce waiting time significantly.

Other advantages of on-demand water heaters include their relatively small size. This means they can easily fit into tight spaces, like under a sink, in an attic, or in a closet. They also don't need to be vented, so they can be installed nearly anywhere in the home.

Finally, on-demand water heaters can often provide higher water pressure than storage tank water heaters — which means a more luxurious shower experience.

How Do On-Demand Water Heaters Work?

On-demand water heaters work by activating an inlet valve when a hot water tap is turned on. This allows cold water to enter the appliance and move through the heat exchanger. The thermostats inside the appliance detect the water temperature and adjust it as needed.

The now-hot water is then sent to the appropriate plumbing fixture. Since the water has been heated as it has passed through the appliance, the process requires no time for the water to be heated and stored, as is the case with storage tank water heaters.

Are On-Demand Water Heaters Right for My Home?

The right water heater for a home depends on a number of factors, including the size of the home, the flow rate of the water, the number of hot water fixtures in the home and whether there are any water conservation ordinances in place.

Ultimately, on-demand water heaters are generally a great choice for most residential homes. Plus, if you live in an area where water conservation is emphasized, an on-demand water heater may be a great option because of its efficiency.

What Type of On-Demand Water Heater Is Right for Me?

The right type of on-demand water heater for your home will depend on your specific needs and preferences. You'll likely need to consider factors such as the size of the space you'd like to install the water heater, the water flow rate you need, the recovery rate you need, and the temperature settings you require. Additionally, you'll want to consider the upfront cost, the cost of installation, energy efficiency ratings, and warranties, among other things.

Before you make a purchase, make sure you do your research and work with a professional to determine the best model for your home.
