Conventional & Tankless Water Heaters

The term “conventional water heater” refers to a large tank that stores a large amount of water that’s already been heated. However, when the water is used up, you must wait for the tank to replenish with more hot water. A tankless water heater is just that, tankless. It heats water on demand to cut down on usage and raise efficiency

Conventional Water Heaters: Benefits v. Drawbacks

For some homes, a conventional water heater may actually be the best option. They’re great for large homes or homes with high usage requirements. Think about all the showers you take, the laundry you do, and the dishes you wash. All that water will add up, meaning you may need the increased volume capability of a conventional water heater system.

  • Suitable for large families/homes
  • Most affordable water heating option


  •  Requires yearly maintenance
  • Less efficient than tankless models
  • Higher utility bills

Tankless Water Heaters: Benefits v. Drawbacks

Are you tired of paying to heat water that you never use? For some, hot water is a necessity only for things like showering and doing some laundry. With homes that aren’t large or that don’t feature as many people, a tankless water heater could be your best option. By heating water on-demand, as you need it, you’ll avoid the energy needed to keep a large amount of water heated at all times. This could help you cut energy spending in the long term.


  • Lower utility bills
  • Wall-mounted, space-saving units
  • Lifespan of 20+ years
  • Water heated on demand


  • Higher up-front cost
  • Retrofitting adds even more expense
