Get hot water on demand every time you turn on the faucet with a tankless water heater. Choose from our selection of tankless water heaters from brands like Ecosmart and Titan to bring instant hot water to your home.

How Does a Tankless Water Heater Work?

Tankless hot water heaters do as their name implies: provide hot water without storing it in a tank. Instead, tankless heaters heat cold water instantaneously and on demand. In theory, they provide an endless supply of hot water when you need it. The wide range at Ace delivers simplicity and ease while also increasing your home’s energy efficiency. 

Are Tankless Water Heaters Gas or Electric? 

Tankless water heaters can be either gas or electric depending on the make and model. Read on to learn more about the differences between electric and gas heaters and which may be right for your home. 

Electric Water Heaters

If you want to make your instant hot water heater electric, enjoy easy installation with our range of wall-mountable electric tankless hot water heaters. Save both space and money compared to conventional electric hot water heaters with tanks. Search the selection of easy-to-use, lightweight models at Ace to find the right size and output to match your home’s needs.

Our electric heaters may offer several advantages, including:

  • Reliable heat exchangers providing near total energy efficiency
  • Compact size and lightweight design
  • Units with built-in flow sensors 
  • External temperature control knob

Natural Gas Tankless Water Heaters

Tap directly into your municipal distribution system with a gas tankless hot water heater. Clean-burning and efficient, these models bring a sleek, low-profile design to your water heating configuration. Ace typically offers various sizes and BTU ratings to help you find the option that best suits your home as well as other features, including: 

  • High hot water maximum output ratings

Can Tankless Water Heaters Run on Propane? 

Propane is an efficient option for tankless heaters, delivering more BTUs per gallon of fuel than natural gas heaters while still burning clean. Look for the following competitive features among our selection of high-quality propane tankless hot water heaters:

  • High UED recovery efficiencies
  • California Ultra Low NOx requirement compliance
  • Condensing indoor design
  • PVC-compatible venting
