Frequently Asked Questions About Water Heaters

Here at Rooter Hero Plumbing & Air, we get a ton of plumbing questions, and we are grateful to be a trusted source for answers. On this page, we share some of the most frequently asked questions on water heaters. If you ever need to hire a uniformed plumber for water heater repair, maintenance, or replacement, then call Rooter Hero Plumbing & Air.

What are the different types of water heaters?

There are several different types of water heaters available, with the most common ones being:

  • Tank-style water heaters: Currently the most common type of water heater, its defining characteristic is a hot water heater tank installation that stores water and heats it in batches.
  • Tankless water heaters: Also known as an on-demand water heater, the aptly named tankless water heater does NOT have a water tank. These units readily heat water as it passes through special piping.
  • Heat pump water heaters: Though uncommon, these efficient water heaters move heat from the air or ground to heat the water.
  • Solar water heaters: This type of water heater uses the sun’s energy to heat water.

What size water heater do I need?

There are many factors that play into deciding the right size water heater. For instance, how many people are in your household? Do you bathe often? You should also clarify what type of water heater you have. A tank-style water heater is selected based on the tank size while a tankless water heater is chosen by its flow rate as measured by the GPM, or gallons per minute.

How long will my water heater last?

In general, tank-style water heaters can last between 10 and 15 years while tankless water heaters can last 20 years or a little longer. Of course, yours may last more or less than these estimates. The life expectancy depends on proper installation, appropriate usage, routine maintenance, and timely repairs.

How much does professional installation cost?

A professional installation offers a valuable peace of mind, and the cost to hire a licensed plumber depends on the type of water heater and other factors. Rooter Hero is happy to provide a consultation and offer price estimates UPFRONT.

How do I maintain my water heater?

Water heater maintenance is crucial for effective and efficient results, and there are many maintenance items to consider. These include, but are not limited to:

  • Testing the temperature & pressure relief valve,
  • Draining the tank, if applicable,
  • Checking the anode rod for corrosion,
  • Cleaning the burner or heating element,
  • Inspecting the venting system for secure flow,
  • And checking for leaks.

For comprehensive multi-point maintenance, hire a licensed plumber.

How can I improve the efficiency of my water heater?

Buying an efficient water heater can save energy and lower your utility bills, but there are ways to improve the efficiency of an existing water heater too:

  • Insulate the pipes and tank to reduce standby heat loss,
  • Flush the water heater tank once or twice a year,
  • Set the thermostat to 120 degrees,
  • Install low-flow plumbing fixtures,
  • And install a timed or programmable thermostat.

What should I set the thermostat to?

It is generally advised to set the water heater’s thermostat to 120 degrees. Many people crank their unit up higher, but this can overwork and overheat the water heater – especially if there is mineral buildup in the water heater or tank. Worse, water temperature above 125 degrees can cause skin burn within minutes or seconds.
