The most talked-about type of water heater is the tankless or instant water heater. The tankless heater does not have a reservoir of water to keep heated constantly. It heats the water as it is needed.

If you’re like most folks, You want hot water that is fast and plentiful. You want a heater that heats quickly without costing a fortune. You expect your heater to be robust enough to take a shower while the dishwasher is running. For these reason, a tankless water heater falls short.

The up-front cost is the first consideration. A 40-gallon tank heater only costs about $800 installed. A comparable tankless water heater can run $3500 or more after installation, depending on whether your new heater fits your old fittings.

Another consideration is the level of use. Unless you buy a very hearty tankless heater, it will not be able to multi-task very vigorously. Tankless heaters also have a temperature swing of up to ten degrees--five above and five below the thermostat--and the water can run hot and cold when turned off and on.

Despite their nickname, instant water heaters are not. When you turn the tap, a sensor turns on a fan, then a burner, and finally the pipes get hot and the water is heated. That means a twenty second wait for the heated water.

Tankless heaters tend to get lime deposits which require regular cleaning. Their pilot light is always lit, so the expense of running a tankless heater is not much less than a tank heater. The tankless heater must heat the Plumbing the entire way from the heater to the faucet. After the water is turned off, the plumbing cools. This is the major loss of energy in the system. When the tankless heater is turned on again, it must reheat the pipes anew.

Tankless heaters have had reliability issues in the past, when the product was brand new. These bugs have been ironed out but the companies making tankless heaters have had quality issues previously and could again.

There are many companies making claims regarding the superiority of tankless heaters. When comparing, be sure to use similar models, not a high end heater versus a lesser model. Check into some consumer report web sites or forums with real reviews from real consumers to help you make you decision.

Save Water and Money with a Tankless Water Heater?

A tankless water heater system can save you hundreds of dollars a year on your energy bill. It is also designed to use less water, which will save you money on your water bill. Tankless water heaters are common in European architecture and are beginning to be more popular in the United States. Only Heat the Water You Use The way the tankless water heater works is that there is a heating element that heats the water as it goes through the pipe to the tap that is turned on. Since the water is not heated until someone turns on a tap, there is no need to keep a large amount of water warm during the day and night. Tankless water heaters make it possible to have as much hot water as you need as soon as you need it. They are far more efficient than the traditional water heaters that store several gallons of hot water all the time. No Water Storage Necessary Tankless water heaters eliminate the need to keep hot water on hand in case it is wanted. The water that is used by the tankless water heater is the exact same water that would be used if you turned on the cold water tap. The only difference is that the hot water is heated by a powerful heating element as soon as it passes through the pipe. Eliminating the need for water storage makes the hot water from a tankless system cleaner and more environmentally friendly. Water is Hot Immediately Tankless water heaters deliver hot water as soon as the tap is turned on. You do not have to run the water for a few minutes before it begins to be warm. The heater provides instant water heating as soon as the water passes through it. Tankless water heaters also provide enough hot water for as many applications as necessary. Since there is not a limited supply of water that has been heated, there is no opportunity for the hot water to run out because too many people are using it at once. Tankless water heaters provide an endless supply of hot water that is available on demand.

You live on a third floor with your hot water storage tank in the basement Where would a tankless heater need to be located to work effectively?

A tankless and a gas(with a normal tank) water heater both burn gas to heat the water, so they need vents to bring air into the space where they are located, and a venting system for the exhaust. Some considerations for tankless: 1) they require larger gas supply pipes; 2) they can be placed on most walls, but you still need room around them; and 3) they heat the water as it flows through the pipe, so you still have to deal with the cold water which is in the pipe. I mention the last one because many people think that they will immediatley obtain hot water. For your situation, placing the tankless heater on the third floor would require new gas pipes. Commonly gas pipes are 3/4" in a home, and a tankless unit may need 1" at a minimum. Having the water heater on the same level would provide you with hot water sooner. Placing the tankless unit where the hot water storage tank is may require less plumbing, so it could be an easier task. The water will take longer to heat, and you could be wasting energy of the heated water in the pipe. This can be partially resolved by insulating the hot water pipes. Insulating these pipes is a wise idea for efficiency in either location.


Can a new tankless water heated be attached to old galvanized plumbing?
