Tankless Water Heater FAQS

Q: I’ve heard people say tankless water heaters are unreliable. Is this true?

A: When they were first released, decades ago (tankless water heaters were invented in 1895!), tankless water heaters weren’t as reliable as conventional water heaters. However, continued advances in technology have improved tankless water heaters to the point where they heat water faster, operate more efficiently, and last longer than conventional water heaters!

Q: What size tankless water heater do I need?

A: It’s hard to say without looking at your home and figuring out how much water you need. You can get a rough estimate of the gallons per minute capacity you’ll need by thinking about how much water you use every day. How long do your showers last? How often do you run the dishwasher or the washing machine? Do you ever need to run both at once? When you have an idea of how much water you use on a daily basis, call Wheat & Sons to start looking at tankless water heaters!

Q: What is the average payback period on a tankless water heater?

A: While this varies based on the amount of water you use, how hot you like your water, etc., many people recoup the cost of a tankless water heater in about 3 – 7 years. Considering a well-maintained tankless water heater can last upwards of 20 years or more, your investment will pay you back for years to come!

Q: I’m worried the water from a tankless water heater won’t be hot enough. Is this true?

A: Tankless water heaters come with a thermostat that allows you to set the temperature of the water to any level you want. Many people set their heaters to 120 degrees – the same temperature as conventional water heaters!

To further improve your energy efficiency, you can actually set your tankless water heater’s thermostat a few degrees lower and still get the same temperatures! Since conventional storage tank water heaters have a lot of water to keep hot, you need to set the thermostat higher to keep temperatures consistent. Tankless water heaters heat water on demand so you don’t need to worry about wasted heat!

Q: What are some of the benefits tankless water heaters offer?

A: One of the strongest benefits of tankless water heaters (and one people like the most!) is that unlike conventional heaters, tankless water heaters never run out of hot water. You could literally run the water all day and it would stay the same temperature (though we suggest you don’t do this)! Storage tank water heaters have limited capacity – usually between 40-60 gallons. This is water that goes everywhere: dish washing, clothes washing, sinks, showers, etc. Once the tank is empty, it can be hours before you get another hot shower!
Another benefit is that since there’s no stored water, there’s very little risk of leaks (flooding from water heaters is one of the most common homeowner insurance claims!).
