PROS AND CONS

Tankless water heaters can avoid the standby heat losses related with storage water heaters. However, although gas-fired tankless water heaters tend to have higher flow rates than electric ones, they can waste energy whether they have a constantly burning 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 when you look at the tank so that the energy isn't wasted.

The cost of operating a pilot light in a tankless water heater varies from model to model. Ask the manufacturer just how much gas the pilot light uses for the model you're considering. If you purchase a model that uses a standing pilot light, you are able to always turn it off when it's not being used to save energy. Also consider models that have an intermittent ignition device (IID) rather than a standing pilot light. This device resembles the spark ignition device on some gas kitchen ranges and cookers.

THE WAY THEY WORK

Tankless water heaters heat water- Navien NPE-180A Premium Condensing Tankless Gas Water Heater directly without having the utilization of a storage tank. When a warm water tap is turned on, cold water travels through a pipe into the unit. Either a gas burner or an electric element heats the water. As an end result, tankless water heaters deliver a constant supply of hot water. You don't have to watch for a storage tank to fill up with sufficient warm water. However, a tankless water heater's output limits the flow rate.

Typically, tankless water heaters provide warm water at a rate of 2–5 gallons (7.6–15.2 liters) per minute. Gas-fired tankless water heaters produce higher flow rates than electric ones. Sometimes, however, even the largest, gas-fired model cannot supply enough warm water for simultaneous, multiple uses in large households. For instance, taking a shower and running the dishwasher in addition can stretch a tankless water heater to its limit. To overcome this issue, it is simple to install two or higher tankless water heaters, connected in parallel for simultaneous demands of hot water. It’s also possible to install separate tankless water heaters for appliances — including a clothes washer or dishwater — that use lots of hot water in your home.

Question: Inconsistent water temperatures
Solution: Manufacturers have also tackled this issue. Rinnai, for instance, has added a recirculation pump to its units to make certain that water is released hot from the start and stays that way for as long as it's running. Korean manufacturer Navien goes one step further by including a buffer tank on certain models that stores a ready supply of hot water. That eliminates the cold-water sandwich and ensures consistent temperatures.

Problem: Constant maintenance was required
Solution: During our last long-term testing, scale buildup was a big concern, since it could decrease efficiency, restrict water flow, and eventually damage tankless models. In homes with hard water, installing a water softener was recommended, which added to the upfront costs. Rinnai has addressed this issue by building isolation valves that make routine maintenance and descaling the unit smoother.
