There is a great deal of discuss the benefits and drawbacks of tankless water heaters verses storage tank water heaters. Water Heater Repair Santa Rosa CA is going to start a discussion on tankless heaters today, explaining a few of the claims and discussing the realities. They have benefits and downsides over standard water heaters and it may simply rely on what ones specific usage needs are that will determine which kind of the correct one for ones house.

The standard theory of making use of a tankless water heater is one of being energy efficient. Water is heated up as it is made use of, and not saved in the large tank of a standard water heater, regularly heated so it is ready whenever it is to be used. Likewise, given that they can hang on the wall and use up practically no space at all, they are very useful.

Electrical Usage

Given that tankless water heaters do require 240 volts of electrical power and up to 160 amps to set up, one could have to have ones electrical box updated to accommodate the power need of the unit. For example, and not to get extremely 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.

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.”

Correct Sizing

Tankless systems are sized by the flow rate measured in gallons per minute (GPM). One will should determine when and what ones greatest need of hot water is to correctly figure out the very best size system 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 also 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 in time 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 suggested. Producers do have de-liming directions and normally have a caution light on the unit to recognize when this should be performed. Nevertheless, bear in mind what the producers warranty covers. If it is just against maker’s defect, this will not cover any repairs needed due to ones water quality. In ideal conditions, a tankless system will last much longer than a conventional water heater, which can help justify the higher preliminary product expense and installment expenses, however one will need to be conscious of keeping it running appropriately to earn back ones financial investment.

Service and Repair Costs

These costs are normally higher for a tankless system than a traditional water heater, just to have a heads up. Many individuals generally do not have their standard water heater services too regularly (regrettably) however it is suggested to have a tankless device professionally serviced when a year.

Instantaneous Hot Water

This must not be that big of a deal, but though producers do advertise immediate hot water. Obviously one realized that it takes a minute for the hot water being heated immediately to travel through ones hot water pipe to the faucet or shower. Though, if one is just using the faucet a little the tankless heater’s burner may not ignite if the faucet is not opened up more. For example, a flow rate of one-half gallons to 2 gallons per minute is needed for electric tankless heaters to heat water.

Depending on the amount of hot water one requires at the same time, even more than one system will have to be installed. This is simple to do, but certainly increases the equipment costs at the same time.

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 costs are about $1200 and $300 respectively then too. One will, once more, most likely need an electrical upgrade, as well as a different gas pipe setup (if using a gas tankless heater), and a new ventilation system. An advantage of changing ones water heater with a system just like the existing one is many of these upgrades will not be needed – they are already in place.

Benefits 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 possibly be water damage to ones home. Likewise, one should flush the tank at least once a year to keep mineral build up reduced, however there is the capacity for stinky water smells, bad tasting water, and the development of legionella bacteria in the storage tank if it is not at a high enough temperature level. Standard 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 utilize less gas than a standard gas water heater which does have its ecological advantages. However, a great deal of electrical energy is utilized, for electricity takes longer to heat water than gas. And, a lot of electrical energy is produced from burning nonrenewable fuel sources.


Similar to any sort of innovation, the field of water heating is ever evolving. Efficiency advances are happening with conventional gas and especially electric storage type water heaters. There are various advantages with tankless and traditional heaters that one will should think about.
