Ark Insulation Installers
Central heating installation is a cost and labour thorough attempt. There are many tasks needed to be done from fitting the pipework throughout your house, placing radiators to be ready for use in your rooms, and of course installing the boiler.
While it is possible to install the whole system on your own, it is recommended to have it done by a professional installer due to the complex nature of central heating. On this page, you will find the price and tasks involved with installing a central heating system.
In order to central heating installation, there are many tasks other than just fitting a boiler and radiators. A Central heating installation system is complex and is made up of several components, which will vary based on the type you choose.
Cost Of Installing Central
Think about all the components needed and you can start to visualize the high total price of both supply and labour.
With everything involved, you need to have a general idea of the cost to avoid nasty surprises. If you know the average price of a central heating system, you will be better informed when determining whether an estimate is reasonable or not.
That being said, the type of heating system and the specific details of the installation can vary greatly depending on multiple factors in your home. Because of this, it is difficult to calculate an exact price. Expect a lot of variability in terms of prices and that obtaining multiple quotes and averages is the best way of determining an accurate price.
Gas Heating System Works
Gas heating systems are the most commonly used in the UK. This type of central heating installation is known as a ‘wet system’ where a gas fired boiler heats water, which provides heating via radiators and hot water through the taps in your home. Here is how they work, step-by-step:
- A gas boiler has a continuous supply of natural gas streaming into it from a pipe that goes out to a gas main in the street.
- Gas jets are directed onto a pipe containing cold water, heating it up to approximately 60 degrees Celsius.
- The water pipe makes up one small section of a large continuous circuit of pipe. This network travels right around your home.
- It passes through each hot water radiator in turn and then returns to the boiler again.
- As the water flows through the radiators, it gives off some of its heat, warming each room in turn. The boiler has to keep firing in order to keep the water at a high enough temperature to heat a home.
- An electric pump is used to direct the water flow around the circuit of pipework and radiators.
- Some houses without a connection to the gas network will use liquid petroleum gas (LPG) or heating oil, which work in a similar way to gas but just more expensive to run.
Hot Water Cylinder
In simple terms a hot water cylinder is a water storage tank that is used to contain hot water in certain types of central heating system. This hot water tank is used to provide hot water to your taps and shower. You will often find the hot water tank in the airing cupboard in your house if you have one of these tanks.
Not all central heating systems use a hot water cylinder. For example, central heating installation systems with a combi boiler do not need one as this boiler type heats the hot water on demand and does not need to store any hot water. Traditional boilers and system boilers that are alternative central heating system set ups will require a hot water storage tank.
Types Of Boiler
A combination or combi boiler is the most common type of boiler system in the UK, it will provide hot water on demand and is a great choice for many homes. But it is not the best option for all. Heat-only and system boilers are much better suited than combi boilers in a variety of situations, and the wrong type could lead to significantly higher bills or long delays for hot water.
Heat Only Boiler
With a heat-only boiler, the hot water is stored in a hot water cylinder or hot water storage tank. You will also normally have an on and off switch, so you can heat water in the storage tank when you know you are going to need it, and leave it switched off when not in use after central heating installation.
System boilers, sometimes known as closed vent boilers, are the perfect choice if you think you will need a heat-only boiler but do not want lots of external components. This is because many of these external components are built into the body of the boiler, as with a system boiler.
Electric boilers work under the same principle as traditional gas boilers, other than the fact that they use electricity to heat the water rather than gas. This makes them an ideal option for properties that have no access to mains gas supply or which have gas boiler restrictions, such as listed buildings or bed-sits, giving the benefits of wet central heating without the need for a gas supply.
There are many electric boiler manufacturers in the UK, with models ranging from 4kW to 14.4kW. The size of your home and your heating requirements will determine what kW output you will need. The lower kW boilers are cheaper to buy and their running costs are generally lower, though they may not be as efficient as larger models.
There is a big difference between electric boilers and electric storage heaters. Electric boilers use electricity to heat the water in a wet central heating installation system the same as a gas or oil boiler. Electric storage heaters store up electricity during the off-peak electricity periods and then radiate that heat throughout your home the next day.
