Advantages to on-demand water heaters:
● Tankless water heaters are compact in size, taking up less space than conventional tank type water heaters.
● They can virtually eliminate standby losses – energy wasted when hot water cools down in long pipe runs or while it’s sitting in the storage tank.
● By providing hot water immediately where it’s used, tankless water heaters waste less water.
● You don’t need to let the water run as you wait for hot water to reach a remote faucet.
● A tankless water heater can provide unlimited hot water as long as it is operating within its capacity.
● Expected life of tankless water heaters is 20+ years, compared to 10+ years for tank type water heaters.
● A single central Tankless electric water heater may not supply enough hot water for simultaneous uses such as showers and laundry unless it has the correct output capacity and is properly configured.
● Unless the system is equipped with a modulating temperature control, it may not heat water to a constant temperature at different flow rates. That means that water temperatures can fluctuate uncomfortably – particularly if the water pressure varies in different parts of the house.
● Electric tankless water heaters require a relatively high electric power draw because water must be heated quickly to the desired temperature. In some cases the home’s electric service may need to be upgraded.
Cost and Savings
Tankless water heaters range in price from $200 for a small under-sink unit up to $1,000 or even more for a unit with enough capacity for a whole house. But a tankless unit can last up to twice as long as a conventional storage type water heater, saving on replacement costs. By eliminating standby losses from the tank and minimizing losses from hot water piping, tankless water heaters may be able to cut your water heating energy costs significantly.
Pros and cons of tankless water heaters
● Saves money in the long run – According to Energy.gov, “For homes that use 41 gallons or less of hot water daily, demand (or tankless) water heaters can be 24%–34% more energy efficient than conventional storage tank water heaters.”
● Doesn’t take up much space – They are small and can be installed in more places—even outside on a wall.
● Lasts much longer – Lasts 20+ years. Almost double a traditional water heater’s life.
● Delivers hot water on demand – Provides two to three gallons of hot water per minute on demand.
● Higher initial cost.
