What Is A Tankless Water Heater?

Known as demand-type or instant-on water heaters, tankless water heaters mainly makes hot water whenever you need it. As such, these flash water heaters don’t produce the standby energy losses that are used with the traditional storage water heaters — a feature that will save you tons of cash in the long-run.

How Does A Tankless Water Heater Work?

Have you ever wondered how your hot dishwasher or clothes washer work? Or just how the most remote of bathrooms or hot tubs operate? Tankless water heaters do their jobs without the use of a storage tank.

Your water gets heated with the help of a gas burner or an electric element and travels through a pipe into the device’s unit. So in case you are still wondering, this is exactly how your “instantaneous” water heater delivers a solid task of producing a nearly endless supply of hot water.

Has Flow Sensors

In addition, the installed heater in the unit is equipped with flow sensors which are activated when water is passing through. And with the use of a negative feedback loop, the water is brought to your targeted temperature. As per the unit’s coating, it is armed with durable coatings along with other acid-resistant add-ons to withstand temperatures of 1000 °C

Has High Flow Rates

However, this seemingly constant supply of hot water also has its limits. Your usual tankless water heater provides hot water at a rate of 2—5 gallons per minute while the gas-fired flash water heaters produce an even higher flow rates than the electric ones. With this, your inevitable simultaneous and multiple uses of hot water in your household could also dry up the largest, gas-fired models out there.

But worry not, my hot water-obsessed users, this common problem can now be resolved. By simply installing two or more tankless water heaters on a paralleled system, your aggressive demand on hot water is achieved.

POU, Tankless And Hybrids

Most of the tankless water heaters that reside in your bathrooms are point-of-use tankless types. As such, the water is almost instantly hot upon you choose the temperature and turn the machine on. POU tankless water heaters are more favored than the centrally installed tankless water heaters as no wasted water is left in the supply pipes as soon as you choose to shut it off.

Meanwhile, the hybrid tankless water heaters use a water heating system that combines the features of both the tank-type and tankless water heaters. In a nutshell, your hybrid instantaneous water heater maintains water pressure and the consistent supply of hot water in virtually all the water applications in your household.

Learning The Advantages And Disadvantages Of Tankless Water Heaters

As it also goes for a tankless water heater, your soon-to-be unit will have its own set of advantages and disadvantages. Before you head to the nearest store, it is a must that I cover these for you before I finally divulge my top list for this year’s best tankless water heater.

Advantages

Savings In The Long Haul

Despite the initial high expense of installing a tankless water heater, your spending will be compensated soon as the unit starts operating under a lower energy use.


Unlimited Hot Water

While this equates an ecological downside, the use of a tankless water heater will deliver a flow rate that is almost sure as it is indefinite.


Takes Less Physical Space

Significantly smaller than tank-type water heaters, tankless water heaters can be mounted on a wall or a building’s structure.


Reduced Risks Of Water Damage

As water storage is not present in tankless water heaters, the risk of a rupture or even a tank failure is lessened significantly.


Safer To Use

If you have a fear of reaching dangerous temperature spikes and levels, then tankless water heaters can prevent you from these troubles. Your instantaneous water heaters have a mechanism that precisely controls water temperatures.


Disadvantages

High Initial Costs

To piggyback on this unit’s first advantage, installing a tankless water heater comes at an increased cost. Western countries, for example, have unusually high prices as these types are not statistically dominant.


Noticeable Start-Up Delay

As a tankless water heater only heats water on demand, the idle water in the piping should start at a room temperature.


Lack Of Heat Source Flexibility

As they use either gas or electricity for heat, the design of a tankless water heater may not allow other heat sources that generate renewable energy options.


Incompatible With Recirculation Systems.

As your heater is inactive when hot water is not in use, the devices are not compatible with the passive or convection-based hot water recirculation systems.


Water Will Have A Lower Pressure

Compared to having your own tank full of water supply, the pressure of which is fully controllable by you, you may have to expect a lower supply pressure depending on what is being transmitted in your area.


Dependent On Electricity

Evidently, as all tankless water heaters either rely on gas or electric, this all goes down when either of these elements is down. Meanwhile, tank-type water heaters can still supply the hot water that is stored in the tank.
