There is a lot of discuss the advantages and disadvantages of tankless water heaters verses tank water heaters. Water Heater Repair Oklahoma City is going to begin a discussion on tankless heaters today, pointing out some of the claims and discussing the truths. They have benefits and drawbacks over conventional water heaters and it may just depend on exactly what ones specific use requirements are that will identify which kind of the proper one for ones home.Water Heater Repair Oklahoma City

The standard concept of using a tankless water heater is among being energy efficient. Water is heated as it is used, and not stored in the large tank of a conventional water heater, continuously heated so it is prepared whenever it is to be made use of. Also, considering that they can hang on the wall and take up virtually no space at all, they are extremely useful.

Electrical Usage

Considering that tankless water heaters do need 240 volts of electrical power and up to 160 amps to establish, one may need to have ones electrical box updated to accommodate the power need of the unit. For example, and not to get extremely technical below, a traditional tank water heater has around a 4500 watt heating element, verses 4, 7000 watt elements of a whole-house tankless one.

As for 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 should figure out when and what ones greatest demand of hot water is to properly find out the best size unit to get.

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 in ones house should be analyzed as well in order to get the most out of a tankless water heater. If ones water is high in mineral material, like calcium, they will build up on the coils gradually and reduce the life span of the system. If the water hardness at ones home is above 11 grains per gallon, a water softener would be recommended. Manufacturers do include de-liming instructions and usually have a caution light on the system to identify when this should be performed. Nevertheless, remember what the makers service warranty covers. If it is simply against manufacturer’s defect, this will not cover any repairs required due to ones water quality. In perfect conditions, a tankless system will last much longer than a traditional water heater, which can assist validate the greater initial equipment expense and installation expenses, however one will need to be watchful of keeping it running correctly to earn back ones investment.

Service and Repair Costs

These costs are typically greater for a tankless system than a conventional water heater, just to have a heads up. Many individuals typically do not have their standard water heater services too frequently (unfortunately) however it is advised to have a tankless device skillfully serviced when a year.

Instantaneous Hot Water

This should not be that huge of a deal, however though manufacturers do advertise immediate hot water. Clearly one realized 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 may not ignite if the faucet is not opened up more. As an example, a flow rate of 1/2 gallons to 2 gallons per minute is needed for electric tankless heaters to heat water.

Depending on the quantity of hot water one requires at the same time, even more than one system will require to be installed. This is simple to do, however certainly increases the equipment costs while doing so.

Equipment and Set Up Costs

An average cost range for tankless heaters is around $800 to $1200. A typical storage tank water heater it is around $300 to $500. Set up costs are about $1200 and $300 respectively then too. One will, once more, most likely need an electrical upgrade, along with a different gas pipe setup (if utilizing a gas tankless heater), and a brand-new ventilation system. An advantage of replacing ones water heater with a system much like the existing one is most of these upgrades will not be needed – they are already st up.

Advantages of Going Tankless

No stored water, which in itself has several benefits. Initially, if there was to be a leakage with a tank heater, there might potentially be water damage to ones house. Also, one need to flush the tank a minimum of once a year to keep mineral build up reduced, but there is the potential for smelly water smells, bad tasting water, and the growth of legionella bacteria in the tank if it is not at a high enough temperature. Traditional water heaters use up much more space too.

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 point to weigh is that indeed, tankless systems will use less gas than a traditional gas water heater which does have its ecological advantages. However, a lot of electrical power is used, for electricity takes longer to heat up water than gas. And, the majority of electrical energy is produced from burning nonrenewable fuel sources.


Just like any sort of technology, the field of water heating is ever advancing. Efficiency advances are increasing with conventional gas and specifically electric storage type water heaters. There are different benefits with tankless and conventional heaters that one will have to think about. Do not think twice to let Water Heater Repair Oklahoma City know of any concerns you could have in the choice procedure.
