Benefits of tankless (on-demand or instantaneous) water heaters.
- Tankless water heaters are a reliable source of hot water whenever you need it and at a preset temperature. If the unit is sized properly, you will not run out of hot water even when you’re the fourth person to take a shower in the morning.
- Tankless water heaters operate on demand to heat water only when you need it. This may reduce your annual energy costs by as much as 35%.
- A tankless water heater is up to 40% more energy efficient than a natural gas tank water heater and up to 55% more efficient than an electric tank water heater.
- Professionally maintained tankless water heaters have a longer life expectancy than tank water heaters. They will operate as long as 20 years as compared to an average of 10 years for a tank water heater.
- Tankless water heaters can be safer since they only operate when hot water is needed unlike tank water heaters that are constantly heating and reheating water. Many tankless water heaters have several features to further increase their safety. For instance, some models include monitoring systems that provide information about water pressure and flow; and, if a system fails, it would automatically turn off the heater.
- A tankless water heater is compact in size which takes less space; therefore, you have more options on where it can be installed in your home.
It is very important to rely on a licensed plumber to install your tankless water heater.
Important Factors to Consider When Choosing a Tankless Water Heater for Your Home
Heating your water is the third largest energy user in your home, accounting for about 14% of your utility bill. You can reduce that amount by choosing an energy efficient tankless water heater. Here are some things to consider when selecting a tankless water heater.
Cost. You may lean toward saving money with a less expensive tank water heater, but don’t forget about the energy savings. You may save money on the equipment but not get as much savings on your utility bills. It’s a matter of instant savings verses larger long-term savings.
Power Source. Electric tankless water heaters may place a higher load on your home’s electrical system which can require costly electrical upgrades. Things like not having the correct wire size can be unsafe. Gas and liquid propane tankless water heaters are most commonly used since they are more powerful than electric tankless water heaters. Of course, your home must have access to natural gas.
Flow Rate. Determine the peak water usage to meet your family’s hot water needs. How much hot water will you need if you often have two showers running while the dishwasher and washing machine are also running? What is the resulting required flow rate? Not sure? Use this information as a guide… smaller numbers for newer equipment and larger number for older equipment.
- Faucets: 0.75 gallons to 2.5 gallons per minute
- Low-flow shower heads: 1.2 gallons to 2 gallons per minute
- Older standard shower heads: 2.5 gallons to 3.5 gallons per minute
- Clothes washers and dishwashers: 1 gallon to 2 gallons per minute
Installation and Maintenance. Proper installation is required for your unit to operate at optimal energy efficiency which translates to energy savings. Proper installation takes into account fuel type, climate, local building code requirements, and safety issues. So, it’s in your best interest to have a Williams Comfort Air plumber install your tankless water heater.

Maintenance for Tankless Water Heater
Tankless water are marketed as “low-maintenance” units as compared to regular tank water heaters. While that is true, a tankless water heater is not a “no-maintenance” appliance. It does require preventative maintenance to lessen the chance of future problems. Tankless water heaters can last up to 20 years with proper preventative maintenance.
Hard water is something that can lead to the need for a repair. The tap water that runs through your tankless water heater always has trace elements of minerals that can build up over time within the heat exchanger, plugging up the passages so that water can no longer flow. This causes your water heater to work overtime to heat your water. Eventually this will shorten your tankless water heater’s lifespan and raise your energy bills. Plus, this mineral buildup on the heat exchanger can cause irreparable damage, requiring the replacement of the heat exchanger or the entire unit.
The more minerals there are in your water, the more scaling that occurs. Descaling is a process that removes the buildup in the unit by running a significant amount of vinegar water through the system, followed by flushing the system for about 45 minutes. Flushing the system removes the vinegar and any other debris from the unit.
During a regular maintenance visit, Williams Comfort Air will descale your tankless water heater to make sure there’s no buildup around the heating elements. Regular maintenance will keep your tankless water heater running efficiently and effectively over the course of its lifetime.
