It is just a matter of considering what their advantages and disadvantages are before you choose to buy the right type of water heater for your home. In the case of tankless water heaters, here are the following pros and cons for you to consider.

Advantages

One of the advantages of having a tankless water heater is that it can provide you with considerable cost savings in the long run. Tankless water heaters are more efficient in using energy as compared to storage tank water heaters. They don't need to maintain a steady hot water temperature all the time. They only heat up the water whenever a person opens the water faucet. In the case of conventional water heaters with storage tanks, the heater may continue to use energy even if people are not using any hot water throughout the home.

Another advantage of tankless water heaters is that they are more durable and longer lasting than conventional water heaters with storage tanks. Generally, the tankless variety can last five to ten years longer than tank heaters. Tankless water heaters also occupy less space in the home upon installation. They can even be installed outdoors as well as indoors, giving homeowners more flexibility in terms in finding the ideal place for the water heater. Tank heaters generally require indoor installation in order to take advantage of energy efficiency.

Disadvantages

One of the disadvantages of having a tankless water heater is that it can cost more to buy than tank heaters. They usually cost three times more than the conventional heater. This can be something that buyers should consider. They might need higher upfront cost when buying a tankless water heater.

Despite waterless tank heaters being more energy efficient, they can also cost in some other ways. For one, electric tankless water heaters may consume quite a lot of energy to provide hot water for the home. Gas-fired tankless water heaters may require special venting stainless steel pipes upon installation which ca considerably add into the upfront costs. One of the other disadvantages of tankless water heaters is that they do not necessarily offer instant hot water after opening the faucet. There might be a brief waiting period before the water heater turns on to heat up the water flowing through the source. Knowing these pros and cons may help you choose what water heater might be better for your own home.

Tankless water heaters at home can be optimized with solar or some other water heating systems. It can work out well and the efficiency of any solar water heating system is substantially optimized by the tankless water heating system.

How it works

Storage tanks of typical passive systems have electrical resistance heating elements or gas burners. These are activated in response to thermostatic controlled switches.

Now, these thermostats are set at 135ºF like in a standard stand-alone water heater. On the other hand, the solar collector’s fluid thermostat is generally set at a maximum of 160ºF for safety reasons.

This controls the maximum temperature of the solar heated fluid and can be used to provide hot water to the storage tank with a difference of only 25ºF.

An important note: when the incoming water temperature is 45ºF the temperature rise required to a tank set at 135ºF is 90ºF.

Auxiliary heating source

The auxiliary heating source (the tankless water heater) will be much faster in providing the temperature rise needed. Thus, the solar collector set at 160ºF can increase the fluid temperature by only an additional 25%.

As hot water from the storage tank is being drawn out and used, cold water enters at the same time into the tank. This causes the fluid temperature to drop.

The tank thermostat will then activate the auxiliary heating source (the tankless water heater system) which heats the water again. This heating action done on the water is much faster than a solar heater can do.

Tempered water

When water is used and goes out of the tank, it passes through a tempering valve. This valve regulates the water temperature by adding cold water when needed. This is to insure that the out-flowing water temperature does not exceed that of the preset temperature.

The tempered water flows through the tankless water heater externally mounted down stream of the storage. If the passing water flowing through the tankless water is already hot enough, the water heater does not turn on.

When the water temperature drops, the precise heating controls add only enough heat to the water to bring it up to the desired set point. When the use of water is stopped, the tankless water heater turns off. The solar power heating system is then allowed to return to its work – providing all the heat it can to the stored water.

The tankless water heater does not heat the water unless when needed, and never heats more than what is used. It only adds the heat needed and improves the efficiency of other existing water heating systems.

This saving offers a considerable amount of relief on the budget of simple households and can also boost the funding conservation of offices and establishments in need of hot water. For tankless water heaters there is no demand for storage of hot water as water is only heated during the exact time that it is used. Hot water placed on tanks undergoes continuous heat loss which leads to subsequent energy drain.

Another important aspect on the benefits of these types of heater is the reduction in the risk of water damage. Water damage normally occurs because of improper and inefficient piping or fitting. Water heaters with no tanks have lower risks of water damage since there is no need for storage.

Moreover there is unlimited supply of hot water. Flow rate is an important determining factor on the amount of hot water that can be supplied all throughout a certain area. Since the heating process takes place as water enters the tankless water heating system there is ensured supply of heated water available any time of the day. Tankless water heaters are normally placed on a wall or in the internal aspect of a building or structure. This brings about the lessening of the physical space needed to accommodate such heating machinery.

Another convincing feature of tankless heaters is its capacity to stabilize temperature and water pressure via a mixing and bypass valve which comes with the machine structure. These temperature compensating valves eradicate the misconception that constant usage of tankless heaters usually brings about the decrease in pressure and temperature. The flow control valve is another significant portion of tankless water heaters. This allows for the maintenance of stable temperature within the whole unit thus resulting into a smooth flow in the system.

Tankless water heaters are classic examples of things that can really be worth every penny and every cent. With its benefits and advantages you can really experience life on a higher level.

Tankless water heaters offer variety of benefits including raised energy potency and continual supply of hot water. Andrew Karre, writer of the book The Coomplete Guide to Home Plumbing claims that "a moderate-size tankless water heater will deliver 4 to six gallons of heated water per minute which is sufficient volume to provision a shower or tub and a sink tap or 2.

Nevertheless inasmuch advantages it bring, installing tankless water heater is a massive challenge. As an example, gas fueled tankless water heaters must be vented out of the house with three inches chrome steel vent pipe. You are also needed to install them a twin-pipe system to permit clean air to pipe right into a sealed burner from outside. Electrical tankless water heaters, from the other standpoint, are a little less dodgy to install but involves concerns like meeting minimum supply pipe diameters. This job is best fitted to experienced plumber or a pro installer. Additionally , a permit and on-site inspection are needed for this specific task. The book Gaiam Real Products Solar Living Sourcebook warned not to install your tankless heater outside unless you are in a place where it never freezes. Freezing is the commonly seen problem of these heaters. Sometimes , the gas piping of tankless water heaters need replacement as it needs a bigger gas supply.

An existing half -inch supply line attached to a three / 4-inch at the heater will choke the fuel supply and limit the water heater output. So if the manual claims "3 / 4-inch supply line that implies all of the way back to the gas pressure regulator of the unit. Tankless water heaters must be vented to the outside. Vent pipe isn't included in the unit nevertheless it is generally available at plumbing, building supply, or hardware stores. The vent piping used with the majority of these heaters is bigger than tank type vent piping.

You want to replace the vent and don't conform down to an existing vent size. You have to also make a request for the installer to chop bigger clearance holes as obligatory if doing a retrofit. Venting might be run horizontally as much as ten feet.

The Aquastar FX model and all Takagi heaters use cheap 4-inch single-wall vent pipe. Aquastar endorses ten feet vertical vent at some specific point in the system to improve good flow. And bear in mind ; it isn't legal and perilous to install a tankless water heater in a RV unless the heater is authorized for RV service

Working all the time, tankless water heaters are favored for it's remarkable devotion to duty compared to storage heaters. Popular Science magazine, issue April 1986 enumerated the reasons why it's best to choose tankless water heaters:

1. Less energy, less utility bills - A storage tank is second only to a space heater in its appetite for energy. To keep 50 gallons of water hot 24 hours a day, it would costs you about $200 for gas and $ 450 for electricity annually. With tankless heaters, all you need to do is hook up an electric or gas unit to your hot water line, turn on a faucet, and voila! You'll get a never-ending supply of hot water -- instantaneously. You will surely cut your hot-water heating bill and save your pipes and tank from corrosion caused by water heated to greater than 120 degrees.

2. Manageable water temperature - Most storage-tank heaters maintain water between 150 degrees and 180 degrees which is too hot for anything but a dishwasher. For these, you have to mix in cool water to bring down the temperature. With tankless heater, you can adjust the water temperature to suit the task. At the heart of a tankless heater is a het-transfer mechanism. Ground water, usually at 50 degrees , enters the unit and tripe a flow sensor, If the flow is high enough, a sensor turns on the burners, and the heat is transferred to the water, As long as the faucet stays open, the heater fires up the water - endlessly.

3. Payback is fast - Energy saving varies depending on the installation. You could save more by replacing a storage tank with a tankless heater than keeping the tank and using a tankless booster. While tankless heaters can be more expensive than storage models, payback can be fast. 

4. Tankless water heaters save your pipes - Water can be a nasty thing. Kept above 120 degrees in  a storage tank, the water's alkali calcium will corrode the pipes and tank. The higher temperature, the more severe the damage can be. If unchecked, calcification can shut down a water heater and lead to costly re-piping jobs. Now that unlimited hot water is available, all you have to do is a little planning. If that's too drastic a change, you may consider installing a tanklessheater as a point-of-use booster. This will save energy.

This way, no other faucets in the house would be able to enjoy the hot water produced by the unit.

Thermostatic tankless water heaters are those that are specifically aimed at bolstering or raising temperature of water that is lowered by long pipe runs, sanitation facilities, and dishwashers. This application is common in hospitals, schools, and laboratories where there is a constant need for precise and fast temperature control.

Flow controlled unites are those that could serve two points or water faucets in the house. This application purpose is essential for entire bathrooms, residential showers, summer cabins, apartments, and small houses.

Whole house tankless water heaters are for households that are aiming to significantly cut on costs. These heaters could significantly lower overall water-heating bill by about 5% to as much as 50%. The savings could be possibly greater. This fixture is designed to heat water that is moving through the system. In comparison, the conventional water heater system is heating an entire tank of water and keeping it hot.  

Such whole house tankless water tanks could also be classified into two, namely, those for indoor and for outdoor use. Indoor application is covering water requirements in the entire internal structure of the house. The outdoor type is covering other water needs outside the house like the water requirements in the garage, the garden, or other points outside the house.
