There is a great deal of talk about the pros and cons of tankless water heaters verses tank water heaters. Water Heater Repair Sacramento is going to begin a discussion on tankless heaters today, pointing out a few of the claims and discussing the truths. They have advantages and downsides over traditional water heaters and it could just rely on exactly what ones certain usage requirements are that will figure out which kind of the proper one for ones home.

The basic concept of using a tankless water heater is one of being energy efficient. Water is heated as it is utilized, and not stored in the large tank of a conventional water heater, regularly warmed so it is all set whenever it is to be made use of. Likewise, since they can hang on the wall and use up practically no space at all, they are very practical.

Electrical Usage

Because tankless water heaters do require 240 volts of electrical power and around 160 amps to set up, one may need to have ones electrical box updated to accommodate the power need of the unit. As an example, and not to get overly technical right here, a traditional tank water heater has around a 4500 watt heating element, verses four, 7000 watt elements of a whole-house tankless one.

When it comes to efficiency, According to the Partnership for Advancing Technology in Housing (PATH), and supported by Housing and Urban Development (HUD), “further testing is needed to determine if electric tankless water heaters will match the efficiency of tank-type heaters.”

Appropriate Sizing

Tankless systems are sized by the flow rate determined in gallons per minute (GPM). One will have to identify when and exactly what ones highest demand of hot water is to correctly find out the very best size device to purchase.

Below is the formula for figuring this out from Keltec Inc:

Flow rate (GPM)
Temperature rise ( T ºF)

To determine the size and kilowatt rating you need, apply this formula:
“The result of this formula is the maximum kW needed to accomplish your project requirements for on-demand heated water. Other media will vary slightly. This formula is a nearly universal method of calculation for energy input to yield temperature at required water flow.”

Water Quality on the Tankless System

The quality of the water one has at home should be examined also in order to get the most out of a tankless water heater. If ones water is high in mineral content, like calcium, they will build up on the coils in time and decrease the life span of the system. If the water hardness at ones house is above 11 grains per gallon, a water softener would be advised. Manufacturers do include de-liming directions and normally have a caution light on the device to identify when this ought to be performed. Nevertheless, bear in mind what the makers service warranty covers. If it is simply against maker’s defect, this will not cover any repairs required due to ones water quality. In optimal conditions, a tankless system will last much longer than a standard water heater, which can help validate the higher preliminary product cost and installment expenses, however one will need to be cautious of keeping it running correctly to make back ones investment.

Service and Repair Costs

These expenses are generally higher for a tankless system than a traditional water heater, just to have a heads up. Lots of people typically do not have their traditional water heater services too routinely (unfortunately) however it is advised to have a tankless unit expertly serviced as soon as a year.

Instantaneous Hot Water

This must not be that huge of a deal, however though makers do advertise instant hot water. Undoubtedly one understood that it takes a minute for the hot water being heated right away to travel through ones hot water pipe to the faucet or shower. Though, if one is just turning on the faucet a little the tankless heater’s burner might not ignite if the faucet is not opened up more. For example, a flow rate of .5 gallons to 2 gallons per minute is required for electric tankless heaters to heat water.

Depending on the quantity of hot water one requires at the exact same time, even more than one device will should be set up. This is simple to do, but obviously increases the equipment expenses while doing so.

Equipment and Set Up Costs

A typical price range for tankless heaters is around $800 to $1200. A normal tank water heater it is around $300 to $500. Set up expenses are about $1200 and $300 respectively then too. One will, again, most likely require an electrical upgrade, as well as a different gas pipe setup (if using a gas tankless heater), and a brand-new ventilation system. An advantage of replacing ones water heater with a system similar to the existing one is many of these upgrades will not be required – they are already st up.

Benefits of Going Tankless

No stored water, which in itself has numerous benefits. Initially, if there was to be a leakage with a tank heater, there can potentially be water damage to ones house. Likewise, one ought to flush the tank a minimum of when a year to keep mineral build up low, but there is the potential for smelly water odor, bad tasting water, and the development of legionella bacteria in the tank if it is not at a adequate temperature level. Traditional water heaters use up a lot more space as well.

The previous video shows the advantages of tankless water heaters and this video expresses some of the drawbacks of tankless water heaters:


Here is what Consumer Reports has found: “Gas tankless water heaters, which use high-powered burners to quickly heat water as it runs through a heat exchanger, were 22 percent more energy efficient on average than the gas-fired storage-tank models in our tests. That translates into a savings of around $70 to $80 per year, based on 2008 national energy costs. But because they cost much more than storage water heaters, it can take up to 22 years to break even longer than the 20-year life of many models. Moreover, our online poll of 1,200 readers revealed wide variations in installation costs, energy savings, and satisfaction.”

The Center for Energy and Environment says that “A 37% savings of water heating energy per household was found for replacing a typical natural draft storage water heater with a tankless one. However, this savings was not enough to offset the high incremental cost resulting in paybacks from 20 to 40 years.”

Finally, the National Rural Electric Cooperative Association concludes that “Tankless water heaters generally aren’t as energy efficient as well-kept tank water heaters. Insulation, temperature setback, timers, and heat traps can all lower energy costs with tank water heaters.”

One indicate is that indeed, tankless systems will use less gas than a traditional gas water heater which does have its ecological benefits. Nonetheless, a lot of electrical power is utilized, for electricity takes longer to heat water than gas. And, a lot of electricity is produced from burning nonrenewable fuel sources.


As with any kind of technology, the field of water heating is ever advancing. Efficiency advances are happening with standard gas and specifically electric storage type water heaters. There are various benefits with tankless and standard heaters that one will have to think about.
