If you have been thinking for a long time about how resourceful water heaters that use tank are, you must be aware of how big are their energy consumption and the space that they use.
People who knew about this before realized that the need for tankless type of water heaters arises.
However, there are still some individuals who are not accustomed to the new technology and prefer to use the conventional water heaters.
Unknowingly, these on demand water heaters are the solutions to their recurring problems.
Basically, the concept about these heaters is conceptualized from hot water on demand only.
There are several kinds and they require using various types of energy sources to be able to heat water, it can either be electric or gas.
Because these heaters do not use tank, the water is heated up only when there is a need to do so.
The basic component is a heat exchanger that is turned on every time you use the faucet or shower.
There is a switch that activates the flow and can sense it if the water gets inside the pipeline.
Normally, there are two types of heat exchangers, there is a burner that uses gas and the other one is electric coils.
Those that are fired with gas can heat water faster and more efficient.
Tankless water heaters have various sizes and they depend on certain things.
These include the quantity of water that must be heated in a minute, the temperature of water when it gets inside the heater and the desired temperature that you want from the outlet.
In tankless heaters, water is heated on demand where as in water tank heaters water is kept at the preferred temperature through the thermostat.
Hence, the first amount of water that comes out as soon as you turned it on is not yet hot.
Because of this, you will be able to waste water before it becomes hot.
There are two kinds of tankless systems that you can choose from.
You can have the single point, which is normally smaller and is used to give hot water from a single point such as shower.
Because it is placed near the water outlet, a single point heater usually has lesser waiting time to heat the water.
This means less water is wasted.
Fire exchangers that use electricity work well with this type of heater because it is only used to give hot water at a single point.
Thus, most homeowners prefer to use this type of system because aside from using less electricity, it is compact and occupies small space.
On the other hand, multi point water heater is a system that can heat more amount of water per minute and can supply hot water to several points all at the same time.
Because they need more energy to heat large amounts of water, they normally use gas.
As for larger houses, you will definitely need more than a single water heating system.
Usually, showers need another multi point water heater since they need more heat.
Because of their additional features, multi point water heater is quite expensive compared to single point water heater.
