What is an on-demand gas hot water system?

An on-demand gas hot water system, also known as a tankless or infinity system, heats water directly as it flows through the unit. Unlike traditional hot water systems that store hot water in a tank, on-demand systems don’t have a tank and instead heat water on demand, which eliminates the standby energy loss that is typical of hot water storage systems.

Why choose an on-demand gas hot water system?

There are many reasons why an on-demand gas hot water system can be a great choice for your home or business, including:

  • Energy efficiency: On-demand systems only heat water when it’s needed, which means they use less energy than traditional hot water systems and can help lower your energy bills.
  • Space savings: On-demand systems are typically smaller than traditional hot water tanks, which means they take up less space in your home or business.
  • Continuous hot water: With an on-demand system, you’ll never run out of hot water, as the system heats water as you use it.
  • Longer lifespan: On-demand systems typically have a longer lifespan than traditional hot water tanks, which can save you money in the long run.

Why is gas preferable to electric for hot water systems?

While both gas and electric hot water systems can be effective, gas systems offer a few advantages over electric systems, including:

  • Faster heating: Gas systems can heat water faster than electric systems, which means you’ll have hot water available more quickly.
  • Lower energy costs: Gas is typically less expensive than electricity, which means you can save money on your energy bills by using a gas hot water system.
  • More environmentally friendly: Gas systems emit fewer greenhouse-gas emissions than electric systems, which can help you reduce your carbon footprint.
