Tankless vs. Tank Water Heater: Why Tankless is Better

The Ecosmart tankless water heaters are superior to old-fashioned tank heaters in every way. Their unique self modulating technology is eco-friendly, provides an endless supply of hot water on demand, and is highly energy and cost-efficient. Let’s compare tankless vs tank water heater to see the differences:

Hot Water Supply:

Tank: A finite supply of hot water, limited to the amount stored in the water heater tank. This means running out of hot water in the middle of showers, an inability to use multiple hot water applications at the same time, and waiting up to 40 minutes until the tank refills with hot water once it has run out. tank vs tankless

Tankless: Unlimited hot water on demand! Never run out of hot water again while showering or washing dishes. A family can take one shower after another in the morning and the last shower will be just as hot as the first. Hot water on demand also means that multiple hot water applications can be used simultaneously, something that conventional tank water heaters simply cannot handle.

Energy Efficiency:

Tank: Conventional tank water heaters are terribly inefficient. They are designed to store a specific amount of water at the temperature set on the thermostat. The entire tank of water is heated to the set temperature, at which point the heating elements turn off. However, heat loss throughout the day causes the heating elements in a tank water heater to kick on periodically just to re-heat the same water back up to temperature. In other words, even when no water has been used, the tank heater has to run. The stand-by mode can account for 15 – 30% of the unit’s total energy consumption. That would be like keeping your car running all the time just in case you might want to go somewhere later. It is shockingly inefficient and wastes huge amounts of energy and money, and that is just when the tank heater is sitting idle.

When a hot water application like a shower or dishwasher is run, the energy consumption of a tank water heater increases. It must run at maximum power to heat up the new cold water which flows into the tank to replace the hot water being drawn. The cold water mixes with the heated water in the tank, which brings down the temperature of the water which has already been heated, meaning that same water has to be heated again, wasting energy and money. 40 minutes after a 10 minute shower has ended, the water in a conventional tank heater is finally back up to temperature again – until the inevitable heat loss occurs and the whole inefficient cycle starts all over again.

Tankless: The Ecosmart Tankless Water Heater is 99.8% energy efficient. It only runs when hot water is actually in use – that’s it! When no hot water is needed, the tankless water heater consumes no energy. This solves the problem that tank water heaters have of heat loss while the tank sits idle. The Ecosmart has no wasteful “stand by” mode. The result: up to 60% savings on your energy bill!

When a hot water application is turned on, Ecosmart’s innovative self-modulating technology constantly monitors the temperature of the incoming water, the flow rate, and the desired temperature setting to ensure that it only uses the exact amount of energy required to keep the water temperature consistent. The readings are processed, calculated, and adjusted at a rate of 60 times per second, which is why the Ecosmart is the most energy efficient water heater on the market – tankless or tank.

Cost to Own and Operate:

Tank: Did you know that the average tank hot water has a lifespan of only 8 – 10 years? That means that every 8 years or so, another bulky hot water heater ends up in a landfill, and the homeowner has to buy a new one. If the water heater tank ruptured when it failed, there can also be costly water damage to the home. The energy cost of operating a conventional tank hot water heater are significantly higher than those of an energy -efficient tankless water heater. A family of four can save an average of over $250 a year just on their daily showers by switching to a tankless water heater!

Tankless: The initial cost of an Ecosmart Tankless Water Heater is comparable to that of a conventional tank water heater. It is designed to be a complete kit; unlike a tank water heater, the Ecosmart requires no secondary hot water lines, valves, or additional materials which keeps the installation costs to a minimum. The American designed Ecosmart uses only the finest materials. Our proven record of quality, safety, and reliability allows us to offer an industry leading 100% lifetime warranty on all Ecosmart Tankless Water Heaters when installed by a licensed plumber or electrician. The Ecosmart is literally the last water heater you will ever have to buy! Factor in the hundreds of dollars you will save on energy annually by switching to an Ecosmart from a tank water heater, and it is clear to see that the Ecosmart will pay for itself many times over.

Eco-Friendliness

Tank: A tank heater is not eco-friendly. It wastes tremendous amounts of energy because it has to re-heat the same water stored in the tank multiple times to keep it at the temperature set on the thermostat. Storing all that unused water in the tank is also not environmentally friendly. Imagine a new development of 600 homes with 50 gallon water heater tanks was to be built: the initial environmental impact of that one small community would be 30,000 gallons of water drained from local sources. Factor in that the average tank water heater spends only 8 – 10 years in use before ending up in a landfill, and it is clear that a tank water heater is not an environmentally sound choice.

Tankless: The Ecosmart Tankless Water Heater is the greenest water heating appliance available anywhere! Its unsurpassed energy savings of up to 60% over conventional tank heaters greatly reduces the environmental impact of operating an Ecosmart, while saving you money. Because tankless water heaters store no water, their water conservation benefits are indisputable. The lifetime warranty means that once you buy an Ecosmart, you will never add another tank water heater to the landfills again. At Ecosmart, the most advanced technology is used to make the most eco-friendly water heater on the market.
