What is an On-Demand Water Heater?

An on-demand water heater (also known as a demand/tankless/instant water heater) is a type of water heater designed to heat water only as needed, rather than storing the hot water in a large tank as with a traditional storage heater. Tankless water heaters can be gas, electric, or hybrid, and vary in their range of capacity and power.

When a hot water tap is turned on, the water heater contacts a cold water feed—usually the municipal water supply—to draw cold water into the appliance. Once inside, the cold water passes through an internal heat exchanger, heats up rapidly, and then exits from the unit as hot water. Rather than maintaining a large tank of hot water at all times, this heat-on-demand system helps save energy and conserve water—as hot water is only produced when needed.

Benefits and Drawbacks of On-Demand Water Heaters

As with all systems, there are advantages and limitations to on-demand water heaters.

Benefits include:

Energy Efficiency: On-demand water heaters are significantly more energy-efficient than standard storage tank systems, often consuming 20-30% less energy. Following installation, you can effectively reduce energy costs and carbon emissions from your property.

Unlimited Hot Water: Unlike storage tank systems, which have limited capacity for storing hot water, on-demand water heatersheater can provide a near-constant stream of hot water for as long as necessary. This makes them ideal for large households or commercial properties with high hot water demands.

Space-Saving Design: On-demand water heaters are typically smaller than standard storage tank systems, allowing for installation in tight spaces or areas with limited space.

Drawbacks include:

Higher Initial Costs: Although on-demand water heaters have significantly lower operating costs, the initial purchase price is normally higher compared to traditional hot water tanks. This is because they're typically more technically complex—and therefore more expensive—to install.

High Fluctuations in Water Temperature: Another potential drawback of on-demand water heaters is the rapid changes in the water temperature at the start and end of a hot water cycle. This is because the system takes some time to 'reload' after the water flow has been stopped and started several times in a short space of time.

Local Regulations and Your Water Heater

Before you install an on-demand water heater in 78753, Austin, it's important to understand the local water supply regulations. This zip code is served by the local municipal water supply system, which imposes various regulations on water heater capacity and installation.

If the water heater is powered by natural gas or propane gas, the unit must be correctly ventilated and conform to local and national code standards. Equally, electric water heaters and tankless units must be installed in accordance with the stipulated standards.
