Never Run Out of Hot Water,
April 26th, 2010 | 
Author: It is possible to never run out of hot water again no matter how many people have taken a shower before you. This was just a dream not too far in the past. Those with large families dreaded the long line of washing and taking a shower due to the limited amount of hot water the tanks would hold.
On average, a hot water heater tank would hold 40 gallons of hot water ready for use. As the hot water is being used, additional cold water is being released into the tank so its level is maintained. This reduces the amount of accessible hot water to approximately 20 gallons before there is a significant temperature decrease.
A byproduct of readily accessible hot water from traditional water heaters is the fact that the heated water can have more suspended solids because of the elevated temperature. These solids are salts that when left in the pipes precipitate out and collect on the walls of the pipes in the system. Over time, the buildup of these precipitated solids will reduce the water flow from the pipes.
With tankless hot water systems, both of those disadvantages are eliminated. Hot water is produced upon demand for any length of time that it is called to do so. The amount of dissolved solids is also reduced since there is not a chance for them to build up like in the old style water tank before the water flows through the pipes.
Most tankless hot water systems are slightly more expensive than the traditional hot water heaters. On the other hand, there is an 80% reduction in the energy that is needed to produce the accessible hot water. The savings you will incur on your energy bill, along with the fact that you will never run out of hot water, makes it the most popular choice for hot water systems being installed in most homes today.
Another benefit of the tankless system is that energy is not being used just to keep a tank of water at a set temperature. The old style heating would cycle on and off as the stored water cooled off whether you were using it or not. This new method uses energy only as the hot water is being used.
