Regardless of the ease of use of tankless water heaters make sure that before you go ahead and buy one for your household that you thoroughly think about how much hot water your family uses for bathing, washing up and other household needs because tankless water heaters have a heating capacity.

Moreover, you will need to think about how many household appliances are going to be using the hot water, this step is crucial in determining whether the tankless water heater will be strained once installed.
Keep in mind that household appliances such as washing machines and dishwashers are capable of heating the water by themselves because they come with a built-in heating coil inside the mechanism.
Furthermore, depending on whether you value convenience or comfort you could choose a standard tankless water heater or a more premium one.
The main difference between the two is that the latter has a larger water capacity and tends to heat water quickly due to the much more powerful heating coil.
Both types of tankless water heaters offer ease of use and maximum convenience as you will only need to turn the switch for the tankless water heater to start heating the water.
However, remember that with tankless water heaters as opposed to traditional water heaters you will have far less control with water temperature.
Despite these minor disadvantages, tankless water heaters are still great because you can turn them on only when needed thus this way you can save electricity and as a consequence have far lower electric bills throughout the year.
Nowadays, you can find a great variety of tankless water heaters ranging in color, design, functionality and volume capacity.
Thus, if you have a large household and family then you will still be able to find just the right tankless water heater for your home.
What are demand-type tankless water heaters?
Demand type tankless water heaters are often also called efficient tankless water heaters because they come with a fairly small hot water reservoir thus they are only used to heat up small volumes of water on demand.
In other words, you could use these heaters to heat just the right amount of water to take a shower and bath. This way you would not have to heat large volumes of water that will then cool down and will need to be reheated as this will lead to increased and unnecessary electricity use.
Moreover, demand-type water heaters are much easier to use and maintains as opposed to standard tankless water heaters.
The demand-type water heaters work the following way:
- You turn on the demand-type heater
- Water starts flowing through the internal heating system and passes the heating coil, this heats the water
- You get hot running water from the tap
Also, keep in mind that some old models of demand-type water heaters can use gas to heat up the water as opposed to modern models that use heating coils for these purposes.
If you will have a choice then always go for the latter one because water heaters with gas heating elements can be hazardous and cause potential burns or even fires if all the safety precautions are not followed.
Moreover, such water heaters with gas heating elements will not be suitable for use in households that have pets or small children.
Furthermore, the latest models of tankless water heaters go through several stages of testing and are certified by leading institutions.
How much hot water can tankless water heaters produce?
Standard tankless water heaters can produce on average about 15-20 liters of hot water per 60 seconds. On the other hand, tankless water heaters with gas heating coils can produce about 25-30 liters of water per minute.
Regardless of what type of water heaters you will choose to purchase and install, keep in mind the number of family members because that will directly correlate to the volume of tank that you will need to look for.
Also, remember that if you are the type of individual that sets the dishwasher and the washing machine at once at night to run then make sure that there will be enough hot water for them to use and that the tankless water heater does not get overwhelmed.
Some families with large household even opt to purchase and install two tankless water heaters for best results.
