How to Choose the Right Water Heater for Your Home

Choosing the right water heater can feel overwhelming, but the right model will save you money and provide hot water when you need it. Here’s a step-by-step guide to help you find the perfect water heater for your household.


  • Small Homes or Apartments: A 20-30 gallon water heater or a tankless unit like the EcoSmart ECO 11 will meet your needs​.
  • Large Families: A Rheem 50-Gallon Gas Water Heater provides ample hot water for multiple showers and appliances​.

  • Gas Water Heaters: Best for larger homes with high water usage. Rheem Performance 40-Gallon Gas Water Heater provides reliable hot water and works during power outages​.
  • Electric Water Heaters: Cheaper upfront and easier to install. The EcoSmart ECO 27 offers energy savings and is great for homes with limited space​
  • Tankless Water Heaters: Provide endless hot water but require professional installation. The Stiebel Eltron Tempra 36 Plus is an efficient option for larger homes​

Water heaters account for a large portion of home energy use. Choose models with Energy Star certifications and self-modulating technology to reduce energy bills. Solar water heaters are also an eco-friendly option, though they may be less effective in Wisconsin’s winter months.


Gas heaters typically have higher operating costs but lower upfront prices. Tankless models have higher initial costs but offer long-term savings due to their efficiency.


If you have hard water, install a water softener to prevent mineral buildup that can damage your water heater.
