Tankless water heaters are relatively new home appliances that ensure you have piping hot water at the ready while taking up as little space as possible and using energy efficiently. Tankless water heaters can be up to 34% more efficient than a conventional storage tank-type water heater, which can save the average family $100 per year. But before you head to the appliance store to purchase one for your home, there are a few key factors to consider.
The total cost of a tankless water heater will depend on its size and fuel type. Gas-powered tankless water heaters cost between $1,000 and $1,500, while electric units cost between $500 and $1,500.
Professional installation is an added cost that can vary depending on who you hire, how big the tank is and how complex your system is (i.e. if venting is needed). The average cost to install a tankless water heater ranges from $2,500 to $4,500.
Propane or natural gas-powered tankless water heaters often heat water more quickly than electric tankless water heaters can. Gas and propane are also less expensive than electric power, but they cost more to install than electric heaters and require more maintenance.
By extracting heat from the exhaust before releasing it into the venting system, condensing tankless water heaters eliminate the need for expensive flue pipes and venting materials. And they use that extracted heat as an additional way to heat water.
Typically, condensing tankless water heaters are more expensive to purchase than their non-condensing counterparts. But they have lower installation costs and higher energy efficiency, so the cost is lower in the long run.
Non-condensing water heaters use heat exchangers to heat water and then vent the exhaust outdoors. They need stainless steel flue pipes to withstand the heat of the exhaust, which can increase installation costs.
You can determine the right size for your home by figuring out how many fixtures you will want to operate simultaneously and how much hot water each one uses. Added together, this will give you the desired capacity of your hot water heater.
We recommend that you get your tankless hot water heater serviced by a professional at least once a year. Increase that to twice a year if you live in a very cold area or if you consistently have hard water.
Installing a tankless water heater is not a DIY project. Your home may need to be updated to accommodate your new water heater, which often requires new wiring or gas lines. Gas and electricity are very dangerous to deal with, so we highly recommend leaving this project to the pros.
Some municipalities even require professional water heater installation. A professional will know to abide by all current codes involving things like carbon monoxide emissions, thermal resistance, venting and more.
Tankless water heaters, also known as demand-type or instantaneous water heaters, provide hot water only as it is needed. They don't produce the standby energy losses associated with storage water heaters, which can save money. Here you'll find basic information about how they work, whether a tankless water heater might be right for your home, and what criteria to use when selecting the right model. Check out the Energy Saver 101: Water Heating infographic to learn if a tankless water heater is right for you, and our #AskEnergySaver discussion on water heating for more answers on efficient water heating.
Tankless water heaters heat water instantaneously without the use of a storage tank. When a hot water faucet is turned on, cold water flows through a heat exchanger in the unit, and either a natural gas burner or an electric element heats the water. As a result, tankless water heaters deliver a constant supply of hot water. You don't need to wait for a storage tank to fill up with enough hot water. However, a tankless water heater's output limits the flow rate.
Tankless water heaters avoid the standby heat losses associated with storage water heaters. However, although gas-fired tankless water heaters tend to have higher flow rates than electric ones, they can waste energy if they have a pilot light. This can sometimes offset the elimination of standby energy losses when compared to a storage water heater. In a gas-fired storage water heater, the pilot light heats the water in the tank so the energy isn't wasted.
The cost of operating a pilot light in a tankless water heater varies from model to model. Review the manufacturer's literature to determine how much gas the pilot light uses for the model you're considering. Look for models that have an intermittent ignition device (IID) instead of a standing pilot light. This device resembles the spark ignition device on some natural gas furnaces and kitchen ranges and ovens.
Proper installation depends on many factors. These factors include fuel type, climate, local building code requirements, and safety issues, especially concerning the combustion of gas-fired water heaters. Therefore, it's best to have a qualified plumbing and heating contractor install your demand water heater. Do the following when selecting a contractor:
If you're determined to install your water heater yourself, first consult the manufacturer. Manufacturers usually have the necessary installation and instruction manuals. Also, contact your city or town for information about obtaining a permit, if necessary, and about local water heater installation codes.
After your demand water heater is properly installed and maintained, try some additional energy-saving options to help lower your water heating bills. Some energy-saving devices and systems are more cost-effective to install with the water heater.
Gas-burning tankless water heaters should operate for 20 years or more, two or three times longer than tank-type heaters. Tankless electric units have shorter life spans, on the order of 7 to 10 years.
Owners of vacation homes know well how long it takes to drain a water-heater tank before closing up a house for the winter. With a compressor, you can drain a tankless heater in a few seconds; then you just unplug it.
When the distance between heater and fixture exceeds 50 feet, look for units with a built-in recirculation pump, which saves water and reduces waiting time. The pump, which can be turned on by a timer, a push button, a motion sensor, a smart speaker, or a smartphone (above), pushes the cold water in the pipes back through the heater.
Noncondensing tankless gas heaters use stainless-steel vents that can withstand high exhaust heat. Condensing units have a cooler exhaust, and use less expensive PVC pipes. A concentric vent, which has an exhaust pipe inside a larger air-intake pipe, simplifies installation because only one hole needs to be cut in the wall.

The water pressure will be much lower than when you use a tank water heater because the heating elements take a certain amount of time to heat a certain amount of water. They produce a flow rate around 2 to 5 gallons (7.6 to 18.9 liters) of hot water per minute, though some can get up to 11 gallons (42 liters) per minute.
While your tankless water heater can provide endless hot water for one tap, it can't also supply hot water to the washer, sinks and other showers all at once. If you typically have multiple taps using hot water at the same time, you'll want to install two or more tankless water heaters to keep up with the demand.
You can purchase either a gas or electrically heated tankless unit. There are some benefits to each. For example, tankless water heaters usually need larger gas lines than conventional water heaters. This will typically make installation more expensive than electric.
Gas tankless water heaters can heat water faster, though, allowing them to supply higher water pressure. On the other hand, the pilot light is always on, even when you don't need hot water. This can make them use more energy than electric units.
To figure out what size of tankless water heater you need, you'll need to do a little research. First, add up the flow rate. This is the gallons per minute of hot water you will use at any given time. This includes any washers, dishwashers, showers, tubs and sinks that you run at the same time. A Google search of your appliances and shower heads will give you a good idea of the flow rate. 59ce067264
