Factors involved in the water heater price

Before digging into the average prices for each type of water heater, let’s take a look at the factors that are involved in the water heater’s price.

  • Tankless or tank-based. This is probably the main aspect that decides the cost of your new power heater. Tankless water heaters are way more expensive than the alternative. They can even cost two or three times the price of a tank-based water heater. However, they may be more expensive, they are more energy-saving, and they are more durable. In the long term, therefore, the tankless unit could be the cheapest option.
  • Efficiency rating. As you may know, every home appliance comes with an efficiency score. High-efficiency models are better because they cut down your monthly expenses, but they are more expensive.
  • Size: of course, the bigger your water heater, the more expensive it’ll be. In particular, if you’re purchasing a tank-based water heater, there can be a lot of difference between the price of a small unit and the one of a bigger unit.
  • Gas or electric unit. Electric units are cheaper, but they determine a higher cost in the long term.
