Tankless Water Heater Cost – How It Saves You Money?

Ecosmart Tankless Water Heaters offer the luxury of unlimited hot water on demand at a competitive cost. Their patent-pending Self-Modulating technology makes the Ecosmart the most energy-efficient water heating appliance on the market. What this means for you is big savings on your energy bills – up to 60% savings over conventional tank water heaters. In fact, most households can expect to recover their initial investment in a new Ecosmart model in under 18 months! Learn more about what makes the Ecosmart Tankless Water Heater the best value in hot water heating for your home.
Affordable to Purchase: The Ecosmart Tankless Water Heater is the most technologically advanced water heater on the market, yet it costs about the same as a conventional tank water heater.
Inexpensive to Install: Unlike tank water heaters, the Ecosmart Tankless Water Heater requires no extra hot water lines, valves, or other special materials. You will save money on both cost of supplies and the installation labor time of your plumber or electrician.
Lasts a Lifetime: The average tank hot water heater lasts only 8 -10 years. For a similar cost, you can purchase an Ecosmart Tankless Water Heater which will last you a lifetime, guaranteed. Why would anyone buy an appliance which is destined to fail when they can have one which will deliver superior performance and last a lifetime?
Dramatically Lowers Energy Costs: The Self-Modulating technology of the Ecosmart makes it 99.8% energy efficient. What that means for the homeowner is a dramatic reduction in their energy bills. Hot water heating represents about 25% of the average electric bill. The Ecosmart can save up to 60% over the cost of operating a standard tank water heater, and it is also the most efficient of all the tankless water heaters on the market. Slashing your water heater’s energy consumption equals big savings off your utility costs, and it is eco-friendly too!
Self-Modulating Technology Saves You Money: An old-fashioned tank water heater is terribly inefficient, which wastes your money. This is what happens when you take a 10 minute shower heated by a conventional tank water heater:
For this example, we will assume that the tank hot water heater is set at 125F, with a water flow of 2GPM (gallons per minute), a city water inlet temperature of 55F and an actual shower outlet temperature of 105F. Most tanks have 2 heating elements rated 240V at 4500 watts each. Generally only one element works at a time. Starting with a full tank of hot water, at 3 minutes into your shower one of the heating elements kicks on, because as warm water flows out, it is replaced by incoming cold water. Not only does the new cold water needed to be heated, but it mixes with the already heated water, bringing down the temperature of the water stored within the tank. In other words, the tank heater has to re-heat the water it has already heated as well as heating new cold water, all the while consuming energy. Think about how wasteful that is!
When your shower ends at the 10 minute mark, the work of the tank hot water heater is not done! It takes approximately 45 minutes for the water in the tank to be heated back up to the temperature set on the thermostat. So for a 10 minute shower, the tank hot water heater has actually been running and consuming energy for 52 minutes. This is how to determine the precise amount of electricity consumed:
4500 watts (the wattage of the tank heating element) ÷ 60 minutes per hour = 75 watts per minute
75 watts per minute x 52 minutes of running time = 3900 total watts or 3.9 KWH
3.9 KWH x 12¢ per KWH = 47¢ per shower
That is based upon an average cost of electricity in the U.S. of 12 cents per KWH – and if you live in the Northeast, California, or Hawaii you are paying a lot more than that. Now 47 cents might not sound like a lot, but if you have a family of four, the annual hot water cost of your daily showers would be $686.20! Keep in mind that is just the electricity required to heat the water for your showers; it does not include the costs of heating water for your dishwasher, washing machine, radiant flooring, pool, spa or other hot water applications.
Now, let’s compare how a tankless water heater does with that same 10 minute shower:
The tankless water heater only consumes energy when hot water is actually being used. That means that for a 10 minute shower, the Ecosmart Tankless Water Heater runs for 10 minutes, not 52 minutes like a conventional tank water heater. The patent-pending self-modulating technology of the Ecosmart constantly measures the incoming water temperature, rate of water flow, and outgoing temperature to ensure that it ONLY uses the exact amount of energy needed to heat the water without any waste. Because it loses less heat than a standard tank water heater, to produce a 105F shower temperature, the Ecosmart only has to heat the water up to 105F, not to 125F like the tank heater. For the 10 minutes during which it runs, the Ecosmart will draw 14,700 watts – a larger amount of watts than for a tank water heater, but because it is for such a brief duration, the total energy used is actually much lower. Let’s do the math to get the precise amount of electricity consumed:
14,700 watts ÷ 60 minutes per hour = 245 watts per minute
245 watts per minute x 10 minutes of running time = 2450 total watts or 2.45 KWH
2.45 KWH x 12¢ per KWH = 29¢ per shower
For a family of four, that comes to a total annual cost of daily showers of only $423.40. That represents a savings of $262.80 just for your showers when you choose an energy-efficient Ecosmart tankless hot water heater over a standard tank water heater. Imagine getting that same kind of savings on all of your hot water applications across the board, and it is easy to see why the Ecosmart Tankless Water Heater pays for itself many times over.
