Traditional water heaters constantly heat a big tank of water, but once it’s gone, you’re stuck waiting. On the other hand, tankless models heat water only when you need it, so you’ll always have a steady, endless supply—no more shivering under a freezing stream first thing in the morning; leave that for the winter.
Benefits of Going Tankless
- Endless Hot Water – No more cold showers! Tankless water heaters provide hot water on demand, perfect for large households or those using multiple appliances at once.
- Lower Energy Bills – ENERGY STAR-qualified tankless heaters use up to 40% less energy, saving the average household $100 or more annually.
- Longer Lifespan – While conventional water heaters last 10-13 years, tankless models can last up to 20 years.
- Compact Size – At about 28″ tall, 20″ wide, and 10″ deep, tankless heaters take up far less space than traditional 60″ tall, 24″ wide tanks.
- Eco-Friendly – Most propane-fired tankless models are made from recycled materials, reducing landfill waste compared to conventional tanks.
- Enhanced Safety – Since tankless water heaters only activate when needed, they have fewer risks associated with overheating and leaks than traditional heaters.
Consider These Factors Before Choosing a Tankless Water Heater
- Replaceable Parts – To extend its lifespan, choose a model with replaceable parts so repairs don’t require a full system replacement.
- Proper Sizing – Tankless heaters are rated by gallons per minute (GPM) and temperature rise. Use the Department of Energy’s guidelines to determine the right size for your home.
- Installation Location – Thanks to their compact design, tankless heaters can be installed on interior or exterior walls, in attics, or even in crawl spaces. Ask your installer about the best placement for your home.
- Gas vs. Electric – Gas-powered models offer higher flow rates, while electric models tend to be cheaper to install. Consider your home’s existing setup and energy costs when deciding.
Making the Switch
With heating water accounting for nearly a third of a household’s energy use, a tankless water heater can be a great way to save money and, more importantly, spare you from those ice-cold winter showers when your old tank runs out of hot water.
