How will you know the right time to upgrade your water heater to improve hot water quality in your home in the Greater Springfield, MA, area?

FSi Oil and Propane wants you to know that the average conventional water heater lasts about 10 years. A lot depends on the water quality in your area and the quality of the water heater itself. Hard water, with its high mineral content, can shorten the life of a unit.

A tankless water heater lasts longer. Because the unit lacks a tank, the chance for corrosion is vastly reduced. The average life expectancy of a tankless water heater is about 20 years.

Tankless (also known as on-demand) water heaters will only heat water when you turn on your hot water faucets. In contrast, conventional water heaters continue to reheat the unused water that sits in the tank, which wastes energy—and money, Compared to conventional storage tank water heaters, a tankless unit can save you as much as 40% on your annual water heating costs.

Other water heater options

Indirect-fired water heaters installed in South Hadley and other towns in our service area use the burner inside your boiler to heat your tap water. An indirect-fired water heater is one of the most efficient water heating options available, and FSi offers professional installation of these units from top manufacturers.

Another choice is a direct-fired water heater—the kind of water heater that you may currently have in your home, or that you may have had in your childhood home. It’s the most common type of water heater, which has a dedicated burner inside to heat water that is stored in a tank. As you use the water in the tank, the supply of hot water is replenished.

Propane vs. electric water heaters

More of our customers are choosing propane water heaters instead of electric units. For starters, the propane models we install cost less to operate and heat water twice as fast as less efficient electric water heaters.

Compared with electric models, propane water heaters require less space and provide more accurate temperature control. They also last longer, and they come in many sizes, with a variety of installation options.

Tankless propane water heaters have become extremely popular, because they double down on efficiency and savings. They heat water on demand—rather than keeping gallons of water hot in a tank, which means that you can save a lot of money on hot water. Tankless units are compact and can be installed almost anywhere.

Water heater maintenance tips

You’ll get longer life from your water heater and prevent breakdowns if you follow these simple guidelines:

  • Every year, have your water heater inspected by a service technician to keep it in peak operating condition.
  • If you have a traditional water heater, drain a gallon of water from the tank every few months. Do this every month if you have hard water. This reduces the amount of sediment collecting in the bottom of the tank, which can make the burner or heating coils work harder. If you’re unsure about how to do this properly, speak with our technician the next time he visits your home.
