There are reasons why the tankless water heater tends to be increasing in popularity in the recent past. Also referred to as instantaneous or on-demand water heaters, they tend to have more benefits as compared to the traditional storage type. But it is good to note that, they have their own limitations and cons which you will need to consider before you decide to go for them. It is good to know the below before you decide that you want to reduce energy bills using tankless water heaters.
Due to their compact size and efficiency in energy, they have become very popular with many people going for them. They are capable of delivering to you hot water on demand by heating it only when you need it. With a traditional hot water heater, it stores water which is hot in a tank and continues to use energy to keep it hot before it is used.
When you have a tankless water heater, your hot shower will not be limited by the tank size, energy will only be used when you are heating the water and not to keep and store water. What it means is that water is only delivered on-demand and not having to sit in a tank somewhere, waiting to be used.
The logic behind the way the tankless water heaters work is very simple. When a hot water tap is opened, there is cold water which runs into the unit of the tankless and the gas burner or the electrical unit jumps into action and ensures that the water is heated as it passes through it. The water then leaves the on-demand unit when it is hot and ready to be used.
On-demand systems are capable of being able to deliver a constant supply of hot water but they are limited to the flow rate of the unit. The flow rate refers to the water amount the tankless unit will be capable of heating at whatever time you put it on.
In case your unit has too low flow rate, it will not be capable of delivering to you enough hot water to meet the needs of your household. When you select a unit which is large enough, it will be good as it will prevent you from running out of hot water.
The tankless water heaters have become very popular in Japan and Europe and in the last decade, they have started gaining popularity in the USA. This could be due to the fact that they tend to be environmentally friendly, are economical to operate and utilize less space. Many people view tankless water heaters as the future. The technology will be improved and with that, the systems will be able to become more popular and thus, the prices will go down and make them be affordable to many people.
