Condensing boilers
Pros: Condensing boilers are the best types of boilers for the environment. Condensing boilers allow you to heat your home in a way that’s much more efficient, and that means you’ll save money on your heating bills and save energy as well.
What’s the difference between condensing and combi boiler?
Unlike an immersion heater, a combi boiler heats your water on demand, instead of storing it in a tank.A condensing boiler is any boiler which uses condensing technology to make better use of the heat they generate from burning fuels such as gas or oil – so a combi boiler can also be a condensing boiler.
How are boilers classified?
Boilers are classified into different types based on their working pressure and temperature, fuel type, draft method, size and capacity, and whether they condense the water vapor in the combustion gases. Boilers are also sometimes described by their key components, such as heat exchanger materials or tube design.
What is PF boiler?
From Wikipedia, the free encyclopedia. A pulverized coal-fired boiler is an industrial or utility boiler that generates thermal energy by burning pulverized coal (also known as powdered coal or coal dust since it is as fine as face powder in cosmetic makeup) that is blown into the firebox.

How do I choose a boiler?
You should consider how much hot water you and your family use, the size of your property, the fuel that is available to you, your existing system and the types of boiler you can have installed. You may also want to consider other factors such as energy efficiency and options for renewable energy use.
How can I tell if my boiler is condensing?
How to tell; If you have a white plastic pipe coming out of the bottom of your boiler you have one of these. Another way to tell is your flue (exhaust) if this is plastic it’s a condensing high efficiency boiler, if it’s all metal a non condensing boiler. No external cylinder necessary.
Does a condensing boiler need a flue?
The regulations and guidelines for boiler flue siting have changed significantly since condensing boilers were made compulsory in 2005.If the flue goes through the roof (a vertical flue) rather than a wall (horizontal flue) then other alterations may need to be made.
Do condensing boilers need a water tank?
Condensing boilers help the environment with an increased efficiency to up to 12% .Space savings: a condensing combi boiler does not need a hot water tank and is available in a wide range of compact sizes, making it much suitable and convenient to fit in a kitchen cupboard than conventional boiler models.
What are the two basic types of boiler?
There are two basic types of boilers: firetube and watertube. The fundamental difference between these boiler types is which side of the boiler tubes contain the combustion gases or the boiler water/steam.
What is a 3 pass boiler?
A 3-pass boiler design is the most efficient way to get the maximum amount of heat from the fuel. The design extracts heat from three times as much interior surface area of the boiler, compared to a single-pass, pin-type boiler design.
What is shell type boiler?
Shell boilers may be defined as those boilers in which the heat transfer surfaces are all contained within a steel shell.1b shows a more efficient method of reversing the hot gases through a wet back boiler configuration. The reversal chamber is contained entirely within the boiler.
Why coal is pulverized?
Pulverized coal firing ensures complete combustion of coal, thus ensuring higher efficiency of steam generators. It is predominantly adopted in large coal-fired utility boilers. The finer the grinding of coal, the more efficient its combustion.
In what form is the coal used in boiler?
Explanation: The coal used for boiler is in powder form, in order to increase thermal efficiency. The different types of coal used in boiler are generally bituminous coal, brown coal and peat. Commonly bituminous coal is most preferred boiler fuel since it has volatile matter from 8 to 33% and ash content of 5 to 16 %.

Using coal as fuel in order to create energy in the form of electricity and/or heat is very common in the world.
How long should a boiler last?
between 10 to 15 years
A good boiler should not only heat your home efficiently but also do it for a long time. If you have just bought a new boiler, you likely do not have to worry about getting a replacement for a good many years. Most modern boilers last for anywhere between 10 to 15 years on average.
How much should it cost to replace a boiler?
A new system boiler costs ?600 – ?900 for a budget model, ?900 – ?1,300 for a mid-range model and ?1,300 – 2,500 for a premium model. A regular or heat-only boiler costs ?500 – ?2,500 depending on the size and quality. You might expect to pay between ?7,000 – ?15,000 for a biomass boiler.
How often should a boiler be replaced?
The average boiler lasts around 15 years if well maintained and although a yearly service can improve the lifespan, an older boiler has to work harder to heat your home. If your boiler needs replacing it could be costing you more money as the energy efficiency is reduced and there is a danger that they are not safe.
