Are Reno Tankless Water Heaters Practical

There is a great deal of discuss the advantages and disadvantages of tankless water heaters verses storage tank water heaters. Water Heater Repair Reno is going to begin a discussion on tankless heaters today, explaining some of the claims and discussing the truths. They have benefits and downsides over standard water heaters and it could simply depend upon exactly what ones certain use demands are that will identify which kind of the proper one for ones house.

The standard concept of using a tankless water heater is among being energy efficient. Water is heated as it is used, and not kept in the large tank of a standard water heater, continuously heated up so it is ready whenever it is to be used. Likewise, because they can hang on the wall and use up virtually no space at all, they are really useful.

Electrical Usage

Since tankless water heaters do require 240 volts of electricity and up to 160 amps to set up, one may have to have ones electrical box upgraded to accommodate the power need of the system. For instance, and not to obtain excessively technical right here, a standard 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.”

Correct Sizing

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

Here 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 have to be examined as well in order to get the most from a tankless water heater. If ones water is high in mineral content, like calcium, they will develop on the coils in time and minimize the life expectancy of the device. If the water hardness at ones home is above 11 grains per gallon, a water softener would be recommended. Makers do have de-liming directions and normally have a warning light on the system to recognize when this needs to be performed. However, remember what the makers warranty covers. If it is simply against producer’s defect, this will not cover any repairs needed due to ones water quality. In perfect conditions, a tankless system will last much longer than a conventional water heater, which can help justify the higher initial equipment cost and installment costs, however one will should bear in mind keeping it running appropriately to make back ones financial investment.

Service and Repair Costs

These costs are typically greater for a tankless system than a traditional water heater, just to have a heads up. Lots of people usually do not have their conventional water heater services too frequently (sadly) but it is advised to have a tankless unit skillfully serviced once a year.

Instantaneous Hot Water

This should not be that huge of a deal, but though makers do advertise instantaneous hot water. Clearly one understood that it takes a minute for the hot water being heated right away to go through ones hot water pipe to the faucet or shower. Though, if one is simply turning on the faucet a little the tankless heater’s burner could not ignite if the faucet is not opened up more. As an 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 very same time, more than one unit will should be installed. This is simple to do, but clearly increases the equipment expenses in the process.

Equipment and Set Up Costs

A typical cost range for tankless heaters is around $800 to $1200. A typical tank water heater it is around $300 to $500. Set up costs are about $1200 and $300 respectively then too. One will, again, most likely require an electrical upgrade, along with a different gas pipe setup (if utilizing a gas tankless heater), and a new ventilation system. An advantage of replacing ones water heater with a system comparable 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 several advantages. Initially, if there was to be a leakage with a tank heater, there could potentially be water damage to ones home. Also, one should flush the tank at least when a year to keep mineral build up reduced, but there is the capacity for stinky water odor, 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 much more space also.

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 yes, tankless systems will utilize less gas than a standard gas water heater which does have its environmental benefits. However, a lot of electrical energy is made use of, for electricity takes longer to heat up water than gas. And, the majority of electricity is produced from burning nonrenewable fuel sources.


Similar to any kind of innovation, the field of water heating is ever developing. Efficiency advances are increasing with traditional gas and particularly electric storage type water heaters. There are different benefits with tankless and standard heaters that one will have to think about.
