On Demand Water Heater, the Answer to Your Water Problems
The tankless water heater is also known as on demand water heater, reflecting the way hot water is produced by this system. There are several factors that may influence your decision to install an on demand tankless water heater which produces instantaneous hot water.
One factor is an increase in your energy efficiency, and the other, the more important factor is the lowering of your energy bill. Traditional hot water heaters always operate turning on in order to heat the water in the tank, whether you need it or not. It is also immaterial if you are using hot water at all.
If water cools, energy is lost, and you have to turn on your traditional heater to heat it back up. This causes a standby loss, i.e., the energy escaping from the water sitting there in the tank.

By switching to a on demand water heater, households can save about 20% off their monthly water heating bill, which accounts for about 15% total expenses.
On demand water heater also enables access to unlimited hot water. This takes place as follows. The heating in an on demand water heating system is activated by the flow of water. So when you demand hot water, at different points, this system can produce hot water for hours, depending upon the size of the system.
A whole house water heater can offer between 2-5 gallons of hot water per minute. This compares to a 35-50 gallon traditional water heater in most homes.
There are two kinds of tankless hot water systems; the gas tankless hot water heater and the electric tankless hot water heater. Usually, electric tankless water heaters are small in size, and are designed for a point of use installation. That means they can be used for one small area in the house.
Compared to this, the gas tankless hot water heater installation is different. With a large heater, they can be used for the entire house. And their installation needs to be done professionally.
Cost is another consideration in selecting a water heating system for your household. On demand water heaters usually cost two to four times of the cost of a traditional hot water heater. But the benefits they give you in value, savings on energy and water bills will more than offset the extra dollar for their initial cost. On top of this, these systems give you a performance over 20 years, compared to the average 12 years by the traditional hot water heaters.
