Turn off your boiler. 4. Turn both filling loop handles to match the direction of the pipe until you hear water flowing. 5.
How does a boiler work?
These gases are made to come in contact with the water vessel, the point where the heat transfer takes place between the steam and water. Thus, the boiler’s basic principle is to convert water into steam with heat energy.
What is a Boiler?
Most commonly, the boiler is defined as a closed vessel into which water is heated the point it is converted into steam at the imperative pressure. The boiler function is either to produce hot water or steam. Hot water boiler heats water for the domestic or commercial purpose heating and hot water supply. Steam boilers generate steam to power turbines for power generation and other various industrial heating applications.
What is the safety valve on a boiler?
Safety Valve: This valve is fitted on the drum, which is used to prevent the boiler explosion due to high pressure, which blows off when the inside pressure exceeds the limit. Always, these are present two in number
What are the components of a boiler?
The main components of boiler include: Super Heater: This heater is used to superheat the steam before it is passed in the turbine as saturated steam that causes corrosion. Feed Pump: We use this to pump the water into the continuous boiler working. Steam or electricity or turbine is used for the feed pump running.
How to calculate boiler efficiency?
Boiler Efficiency (%) = (Heat Exported by Outlet Steam) / (Heat Supplied by the Fuel) * 100
What is steam boiler?
Steam boilers can be used for cooling, heating, cleaning, humidification, and in production processes and also can be used for power generation. Steam boilers can be used in industries like feed, food processing, textile, paper, building materials, metal smelting, heating engineering, and many more.

Why would a boiler stop working?
The general purpose of most new boilers is to heat up and transport water to various different appliances. Almost everybody who owns one got their boiler for hot water, so you can usually assume that it is an issue with the supply or pipes in some way.
How do I know if my boiler is broken?
The easiest way to tell if a boiler has stopped working is to see if there's no hot water. A lack of central heating, radiators that don't provide heat or other obvious signs could hint that something is very wrong with the boiler in terms of its heating system - either the heating itself or the fuel/power that's needed.
Why is my combi boiler not working?
A leaking combi boiler is one of the most well-known causes of a boiler not working. A leak can spring up anywhere in the system and drop the boiler pressure significantly - if it's after the boiler pressure gauge, it might not even get picked up by the readings.
Why does my boiler pressure drop after topping up?
If you find that the pressure on your boiler continues to drop after topping up this may be a sign that there is a leak on your existing system. These type of leaks can be hard to find as it means following your pipework from the boiler throughout your home to every connected point.
What does it mean when there is no pilot light on boiler?
No pilot light or thermostat means that your boiler will produce no central heating or warm water.
What to do if you are not facing a common problem?
If you are not facing one of the common problems, then it might seem like there is not much that you can do to fix the problem. Identifying the issue can be important, and not just because you want to fix it: if you know what is wrong, you can keep yourself safe and make sure that the boiler does not break.
What is the lack of pressure in a boiler?
The lack of pressure is only a problem in pressurised systems and theses include System and Combination boilers which work on a sealed heating circuit. The pressure is created by an expansion vessel which has a diaphragm bladder inside it that contracts and expands with the increase and decrease of volume of water in the system. A conventional boiler or open vent does not have an expansion vessel and relies on a feed and expansion tank. These systems are fine and have been used in the UK for many years but they are slow to react and cannot be used on a combination boiler. [caption id="attachment_2206" align="aligncenter" width="700"] The black needle represents the pressure your boiler has, the red needle (or red area on the gauge should be the overpressure point.Most boilers operate well between 1.5 and 2.0 bar) caption]
Why do boilers drop pressure?
Furthermore if you have only been using the boiler for hot water on either a combi or a system boiler you may find that the system levels have dropped due to natural evaporation or air that was trapped. Trapped air can give a false reading on a pressure gauge so always make sure that you have bled all the radiators before topping up. You also get natural evaporation as you constantly heat and cool the system during the winter so topping up can be frequent but if it is too frequent then you definitely have a leak or an issue.
Why does my boiler shut down?
When your boiler has no pressure, for safety it will shut down. It is always a worry when you come to switch on your boiler after a long period of not using it and you find that the boiler is indicating that there is no pressure. There is no need to panic and first it is better to understand why you don't have any pressure.
What is the largest market for boilers in the UK?
The largest market for boilers in there UK is and has been for many years combination boilers and they make up over 80% of the market sales. They have a built in expansion vessel and require water to be constantly held with in the circuit as they are instantaneous water heaters.
