Is it okay to use three-eighths PEX pipe for a tankless water heater manifold system?

It depends on the length of the run. 3/8 pipe tends to be a little small and will restrict the flow. Use the 1/2 if you can. It's not that much extra but it will give you much better water delivery. Of course, between the manifold and the water heater, use 3/4 inch or larger copper.

I would have to agree with the previous contributor. 1/2" PEX is indeed the preferred size for running the water to the Plumbing fixtures.

How do you install a tanklless water heater?
If you choose to install the water heater yourself, there are instructional videos on the web you can follow, and the item likely comes with instructions in the box. Most companies that sell these items will install it for you for a price.
How to Determine Your Need for a Tankless Water Heater?
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.
What are the benefits of using a natural gas tankless water heater?
Some of the benefits of a natural gas tankless water heater are that hot water is available at anytime, the cost to operate the heater is less than a tank and there may be government grants to entice consumers to use the new system. Overall, energy saving and constant hot water availabilty at the main advantages.
Save Money With A Tankless Hot Water Heater?
A tankless hot water heater is both more environmentally friendly and economically sound than traditional storage units because it only heats water for use on demand as it is needed. These water heaters are less wasteful and generally more efficient. However, smaller units are sometimes challenged in meeting multiple demands for hot water at the same time. For a large family or home, consider purchasing a whole house tankless hot water heater system. Another option is to install multiple tankless hot water heaters to operate the dishwasher or washing machine separately.
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.

The Benefits of a Tankless Water Heater?
When replacing a water heater in your home, there are several different options that you can choose from. They can be found in traditional styles that heat the water in a large tank, or it is possible to get a tankless water heater. Tankless models have become increasingly popular within the past few years for a number of reasons. Though water heaters that do not require a tank can provide a number different benefits, one of the most popular of these is the energy-savings they can offer. Traditional water heaters hold a certain amount of water, and the water must be kept warm at all times. This means that the heater is always on, and it is constantly working to keep the water hot. When the tank is kept in a basement or other area where the temperature remains consistently cool, the tank has to work extra hard, which equates to more energy consumption. Tankless water heaters, on the other hand, only heat water as it is needed. With these models, there is no longer a need to keep water hot and ready to use all times. Instead, they work to heat water when a faucet is turned on. This can lead to very substantial energy savings. In fact, tankless water heaters actually require 40% less energy to operate than traditional hot water tanks. Not only is this better for the environment, it is also better for your wallet. Tankless water heaters are also safer than traditional models. Because they only heat water as it is needed, the water is significantly less likely to become overheated. They also take up much less space in the home, which can be very beneficial for homes where floor space is limited. The initial cost of a tankless water heater is higher than that of a traditional model, but they typically save enough money to pay for themselves with in a few years. Traditional water heaters are designed to last for only about 6 to 12 years. A tankless water heater, on the other hand, can last for 20 years or longer. This helps to make them a better value than traditional models, and it is better for the environment because it leads to less models in landfills.
Does a propane tankless water heater need electricity to ignite Currently have an off grid cottage and a 9000 kw generator Do you need to turn on generator for the tankless to work?
All tankless gas wwater heaters have an electronic ignition system, with one exception, Bosch made one that used the flowing water to turn a small generator to ignite the burner. It was a complete flop and i believe was discontinued. One thing you might concider is that they really DONT use much electric, a car battery with a power inverter will run it for quite a while
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.
What is better turbo system off the manifold or off the exhaust?
Off the manifold.
Why does the antifreeze overflow go empty on a 1999 S 10 blazer?
You have a leak in the cooling system. It could be from a number of sources such as, radiator, radiator hoses, heater core, heater hoses, water pump, intake manifold gaskets, head gaskets, cracked heads and probably a few more. Have the cooling system pressure tested to determine where it is leaking from and don't wait.
Does a tankless water heater require a thermal expansion tank?
In America, local building codes will decide. For example, in Pinellas County, Florida, they are required with every tankless installation, but not required in some surrounding counties. Always use a certified plumber, and hold him/her accountable to meet local Codes via the Inspection process. Contact your local Building Inspection officials for info on equipment requirements and permitting. Expansion tanks are ALWAYS a good addition to a gas or electric tankless system. All of these systems have their own controls that adjust the amount of heat applied to the water in the coils. If these malfunction, overheating may cause a steam bubble to be created inside the tankless heating unit. An expansion tank allows for the extra pressure from this expanded water to be absorbed safely.
