This is why they are also often called instant hot water heaters. The water is instantly heated by running over a heating element on its way to the tap. No more running bath water forever to get it to heat up!

These can use either gas or electricity to heat–depending on whichever is available in your home. This is very energy efficient and will save you money on water and energy bills every month.

Another innovative appliance that Rinnai has is the solar hot water heater. This is similar to the above water heater, except that it is solar powered as opposed to gas or electric. These often actually have tanks, it is not very easy to instantly heat water with solar power.

Commercial tankless water heaters are commonly used for everything including businesses, apartment buildings, hospitals, schools and industrial developments.

The size of the tanks in a commercial tankless water heater usually starts at around thirty gallons and can go up into the hundreds. There are so many different types and models available, but they all generally function in the same manner. The tank remains full at all times and is constantly heated using one of three methods: oil, gas or electricity. When it is needed, the heated liquid is released from the top of the tank while cold liquid enters from the bottom. This is heated and the whole process starts all over again. If there is no immediate requirement for hot water then it remains in the system until it is needed.

Using this type of system does have it’s disadvantages. Since there is no way to tell when it will be necessary to tap into the stored reservoir then it is essential that the system be working at all times. This requires a large amount of energy to keep it going. That is why it has become necessary to develop more energy efficient setups to cut down on the cost associated with them and help eliminate unnecessary energy consumption.
A commercial tankless water heater should also be chosen based on their life expectancy. Paying more upfront for a more efficient unit will pay itself back in the long run in energy savings.
