Tankless water heaters continuously supply hot water to the bathroom and kitchen. Installing tankless water heaters signals a welcome break from the deplete-heat-wait cycle of tank-style water heaters for many homeowners. 

How Do Tankless Water Heaters Work

Tankless water heaters don’t store hot water in reserve. These small appliances, typically mounted to a wall, have an inbuilt heat exchanger that warms water as it passes through them. The pipes in the exchanger circle and connect, allowing many lines to be placed within a small area. It resembles how water in a garden hose will eventually warm up after spending some time in the sun.

Tankless Water Heater Size Guide Considerations

The Size Of Your Home 

The sizes of tankless water heaters vary. However, practically all contemporary water heaters can thoroughly steam your entire home’s water supply. Smaller models can be ineffective because you might only be able to heat the water that enters a few of your home’s bathrooms. 

Well-sized tankless heaters heat as much water as you can run through them, unlike conventional storage tank heaters, which only allow you to store and heat the amount of water you anticipate using. You must not choose a size that produces less warm water than is necessary to fill all of your bathrooms.

Water Flow in Your Home

Tankless water heaters steam water as it enters your home. Your heater controls the water flow from your taps. This lets you operate multiple taps or showers without slowing them down. If one shower head flows at 1.8 gallons per minute, another may start running at the same rate. The tankless water heater must provide enough flow rates for both showers. While those two showers run, other hot water taps and faucets in the kitchen or another bathroom often run, increasing the required flow rate.

Temperature Increase 

Temperature rise is the difference between the winter, or coldest, groundwater temperature in your location and your tankless water heater’s desired set temperature. Find your area’s typical winter groundwater temperature on a map. At your region’s coldest moment, you can use a thermometer to detect water temperature as it comes out of the ground (usually at an exterior faucet). If your chosen tankless set temperature is 120 degrees and your area’s coldest groundwater temperature is 50 degrees, the temperature rise is 70 degrees.

Family Size 

Every home uses hot water when hosting guests or preparing for an occasion. When picking a tank, consider how often these occur. Your tankless water heater requirements should be based on your peak demand, even if you don’t use warm water all the time. If you’re around others and their activities, increase your usage.
