i dont get this question?
A combination boiler provide hot water to a central heating system whereas the multi-point water heater does not. The multi-point water heater provides hot water to multiple appliances or taps at the same time.
Do you mean does it have to run/spin? Yes, it is very important that this fan works otherwise the core will get too hot. if it gets too hot, you risk damaging (melting) components. most computers have a sensor that will shut off the computer if it gets to hot, but to be on the safe side, i wouldn't use the computer until the fan is replaced. However, there is the possibility that you are using a passive cooling setup if your computer is fairly old (more than 5 years) in which case, there shouldn't be a fan so its not a problem as long as it has been running fine up until now. Or, you could have a water cooling setup but if you have to ask about the fan, you probably don't have it water cooled
Depends on what pipe you are asking about. Most pipe such as PVC has a max heat rating for internal and external temperatures. this is why regular white PVC should never be used for hot water from a hot water heater which can be 120 degrees (F) or more and melt regular PVC. That is why they recommend using CPVC which has a higher temperature rating. Depends on what pipe you are asking about.

does it have anti freeze in it? is the electric fan coming on or any fan? thermostat could be bad, or cooling system clogged, bad water pump?
In my heating system the circulation pump pushes hot water around the pipes in my house to all ate radiators. Different systems will have different functions but generally to "circulate a liquid".
Hot water
This is to allow for expansion of the hot water-- otherwise the cylinder would blow up.
burning hot water works best
There are four main types of hot water cylinders: Direct hot water cylinders. These cylinders have an immersion heater inside that heats the water directly. They are the most basic type of hot water cylinder, and they are relatively inexpensive. However, they can be inefficient, and they can take a long time to heat up the water. Indirect hot water cylinders. These cylinders use a heat exchanger to heat the water. The heat exchanger is connected to a boiler, which heats the water from the mains supply. Indirect hot water cylinders are more efficient than direct hot water cylinders, and they can heat up the water more quickly. However, they are also more expensive. Vented hot water cylinders. These cylinders are connected to a cold water tank. The cold water tank is located above the cylinder, and it provides the water that is used to heat the water in the cylinder. Vented hot water cylinders are the most common type of hot water cylinder in the UK. They are relatively inexpensive, and they are easy to install. However, they can be inefficient, and they can lose heat through the venting system. Unvented hot water cylinders. These cylinders are not connected to a cold water tank. Instead, they are connected directly to the mains water supply. Unvented hot water cylinders are more efficient than vented hot water cylinders, and they do not lose heat through the venting system. However, they are also more expensive, and they require a special type of expansion vessel. The type of hot water cylinder that is right for you will depend on your individual needs and requirements. If you are looking for an inexpensive option, then a direct hot water cylinder may be a good choice. If you are looking for an efficient option, then an indirect hot water cylinder may be a better choice. If you are concerned about losing heat, then an unvented hot water cylinder may be the best option for you.
A tray place under the cylinder designed to catch any water that may leak and also available with an overflow to take the water away to a drain or outside, preventing structural damage caused by water leaks.
heat is transmitted by gravity between the boiler and cylinder ina hot water system. this is using the principle of?
It heats water to a desired temperature
At the lowest point on the hot water distributing pipework system
To measure a hot water cylinder, you typically need to measure its height and diameter. Use a tape measure to determine the height from the floor to the top of the cylinder and the diameter across the widest part. These measurements will help determine the cylinder's capacity and size for replacement or installation purposes.
Hot water works just keep rubbing hot water and soap it happend to me
Conduction
answer 2 Assume an electric hot water cylinder. The cold water is introduced at the bottom of the cylinder, for upon heating, the hot water will rise to the top. If you put cold water in at the top, this would cool the hot water you had just paid for! The hot water will be taken from the top, for that is where it will be.In an electric cylinder, there will be an electric heating element about 150 mm from the bottom of the cylinder.[There will always be dirt and crud in the water supply, and some of this will settle at the bottom of the cylinder. Having the element above this will avoid the crud being disturbed each time the element is turned on.]In the electrical circuit to the heating element, there will be a thermostat, to set the highest temperature to which the water will go. This is vital for safety, as water too hot can cause scolding.In addition, the electrical supply authority may only allow you to heat your hot water for certain hours of the day, hours when the demand otherwise is least.A cylindrical shape is chosen, for engineering strength. This will be thermally insulated, otherwise you will lose too much heat.
