Tankless Water Heaters

Water heaters are very helpful devices in anyone’s home as they provide hot water for our everyday needs – for showering, for washing dishes, clothes, etc.  In the old days, traditional water heaters are those that have a tank with them where the hot water is stored.

Nowadays, water heaters can come in different forms, shapes and sizes.  Tank-type water heaters are no longer the only kind of water heaters available in the market.  Tankless water heaters are becoming popular in many areas, and most of these users believe that their tankless water heater units are actually more convenient in many ways unlike tank-type water heaters.  However, due to the fact that tankless water heaters are relatively new to some, especially to those who have always had tank-type water heaters at home, they are quite hesitant or reluctant to buy one.  Moreover, switching from a tank-type water heater unit to a tankless one is quite a challenging decision.  You may have always been using a tank-type water heater ever since for all your hot water needs, but if you are looking to buy a new water heater right now and you are hesitant to switch, then you need to know about some misconceptions about tankless water heaters and understand how it can also effectively help in bringing hot water to you.

Below are 5 misconceptions about the use and efficiency of tankless water heaters:

Misconception #1

A lot of people believe that a tankless water heater unit will not be able to supply you sufficient hot water.  A 50-gallon tank-type water heater unit stores exactly 50 gallons of hot water in its tank.  When all that hot water is used up, water must be reheated to make a new batch, which can take for as long as 30 minutes or more.  Therefore, availability of hot water in tank-type water heaters is actually limited.

Every time you need hot water, a tankless water heater will be able to supply you with it.  There is no need for a storage tank, which means that you will never experience any shortage of hot water.  Water is heated as it goes through a heating element or coils to an outlet.  As long as you require hot water, you will get it.  All you have to do is turn on the tap.

A whole-house tankless water heater unit is designed to provide hot water for a household of 3-5 family members.  Due to the fact that water is heated only when demanded, it will never run out, which makes it possible for more than one individual to shower at the same time, or run the dishwasher and the washing machine at the same time.  There is no limit on how much hot water you can utilize.

Misconception #2

Almost anyone who has not really had a tankless water heater unit themselves is led to believe that these water heaters are very expensive to have and to operate.  In reality, they are not.  As a matter of fact, when you really know how to use a tankless water heater correctly, your expenditures are actually a lot lesser than when you have a tank-type water heater.  Tankless water heaters can really save you about 20% on your total energy bill.

How does it help you save? Tankless water heaters do not have any tank to store the hot water that is not yet being used, so you are not spending more on your energy bill based on the presupposed demand of hot water.  Tankless water heaters are also called on-demand water heaters because they supply hot water only on demand or as needed.  Tank-type water heater units store hot water inside a big 40-50 gallon tank and keep it warm 24/7, an unnecessary expense especially when hot water is not always needed.

Misconception #3

A lot of people are into the notion that tankless water heaters are inefficient.  As already mentioned earlier, tank-type water heaters provide hot water with the use of a storage tank.  A pilot light keeps the water inside it hot at all times.  Because of this design, tank-type water heaters tend to leave a much bigger carbon footprint than their tankless counterpart.  Tank-type water heaters really waste a lot of energy, whereas tankless water heaters do not.

Energy that is minimally used up typically makes the tankless water heater a great eco-friendly choice, so never assume that tankless heaters are costly.  It actually will cost you a few pennies to operate a tankless water heater as compared to a tank-type one wherein you still pay to heat water that is not going to be used yet.

Misconception #4

Many people believe that tankless water heaters does not really deliver a continuous flow of hot water.  They strongly believe that the cold water will typically enter the hot water stream, which is really not true.  Due to the fact that cold water goes through a heating element or coils before it reaches the outlet, you are sure to have a steady stream of hot water.  Just turn on the hot water tap and you get to enjoy hot water instantly.  Do not think that just because a tankless water heater does not have a tank and cannot store hot water, it does not mean that it cannot meet your hot water demand.

Misconception #5

Many homeowners strongly believe that a tankless water heater heats up water to a temperature that is unsafe or harmful to the human body.  This is considered a misconception because tankless water heater units have a thermostat that is adjustable to suit personal preferences.  Simply set the thermostat to suit your hot water needs and you will surely enjoy using hot water at just the right temperature you want.

The thermostat available in tank-type water heaters are very much similar to tankless ones, and it functions mainly to prevent overheating and avoid potential scalding.  You do not need to worry about the water getting too hot for your comfort unless the thermostat has been set too high.  An average thermostat setting in the shower area must not go over 105°F.  The thermostat can easily be adjusted according to your needs and your family’s needs as well.

These 5 misconceptions and the truth about tankless water heaters will convince you to consider trying out a tankless water heater unit for yourself.  Tankless water heaters are actually a great hot water provider, are inexpensive to operate, effective, safe and are very capable of meeting your hot water needs.
