The central heating installation process
At Boilerhut, we follow set procedures to ensure that each installation is undertaken to the highest standards. The central heating installation process will usually take place in the following order:
- Installation of the radiators in rooms around the property – The radiators will be sited first so that the engineer can see where the pipework should connect to. Once this has been done, the radiators will be fixed in place using brackets drilled into the wall.
- The pipework will be laid – At Boilerhut, we utilise copper pipes. These will be laid around your property and will be connected to the various outlets, water tanks (where relevant), radiators, and boiler that make up your central heating system. This can be a time-consuming job, especially where the flooring needs to be taken up.
- The new boiler will be installed – We will shut off the water and gas (if relevant), in order to undertake the installation of the boiler.
- Setting up the heating system – We will make sure that all of the vents on the radiators are closed and then fill the heating system with water. We will then vent the radiators to rid them of excess air. The boiler will then be switched on to warm up the water and we will use the radiator valves to balance the hot water flow around the system.

A recent full central heating installation
In the video, you will be able to see a recent full central heating installation that we undertook in a property development in Cyncoed, Cardiff.
See the full case study here >
The property which was formerly a doctors surgery was being redeveloped into a day nursery and required an upgraded heating system to meet building regulations.
To this property, we installed the complete pipework, all new radiators, and an Ariston Clas ONE combi boiler.
How long will it take to install a new central heating system?
On average, it will take 2 heating engineers between 2-5 days to install a full central heating system. Installation times will vary depending on the size of your property and whether or not you are currently living in the property. If you are living in the property, the heating engineers will need to work around you so the installation will take longer.
Below you will find the typical installation times for various installation scenarios:
Do you need planning permission for central heating?
Planning permission is not usually required for central heating installation, providing the installation isn’t being undertaken in a listed building. If your property is listed and you are unsure whether you will need permission, it is worth checking with your local planning authority.
What is a sealed heating system?
A sealed heating system is a contained loop not exposed to the open air, typically pressurised to around 1 bar. Favoured for its efficiency, sealed systems also reduce common issues like airlocks and system contamination. Combi boilers are a sealed system, as are most new system boiler set-ups.
What is a gravity or open vented system?
Traditional open vent systems are open to the atmosphere and use a feed and expansion tank to regulate pressure and accommodate system expansion, a hallmark of older heating setups.
What size boiler do I need?
Selecting a boiler that matches your property’s heat loss and emitter types (like radiators) is critical to avoid under heating or inefficiency due to short cycling. When discussing your needs, Boilerhut engineers will ensure that all radiators, hot taps and showers are taken into account to ensure that you have the right size boiler.
It’s important to note, that a bigger boiler isn’t always better. If power, in kW (kilowatts) is too high you won’t be running efficiently and will be using more fuel to do the same job a smaller boiler could easily handle. Why pay 50p when you can pay 25p?!
Do I need a magnetic filter?
Magnetic filters are crucial for a clean heating system, trapping both magnetic (rust, steel) and non-magnetic (limescale and dirt) particles, thus protecting the whole system including the boiler’s heat exchanger. This helps improve your boiler lifespan.
Is central heating installation messy?
The process of fitting a new central heating system, or updating an existing one, typically involves a certain level of upheaval in your property. Expect this short-term inconvenience to last for several days. During this period, you may need to remove or lift carpets and be prepared for some dust and debris on your floors and surfaces.
Is installing gas central heating a big job?
Yes. The expense associated with installing central heating in your home encompasses the purchase and installation of essential components such as the boiler, heating controls, an intricate network of pipework, and radiators. For some systems, a water tank may also be necessary. The installation process is quite labor-intensive and involves integrating these elements into your home’s infrastructure.
The overall cost is influenced by the scale and complexity of the installation, which in turn is often a function of your home’s size; larger homes require more extensive pipework and a greater number of radiators to achieve a uniform distribution of heat. Consequently, as the scope of the project increases with the size of the property, so does the financial outlay required to ensure a fully functioning central heating system. It is also worth considering that higher quality or more advanced systems, while potentially more costly upfront, can offer greater efficiency and cost savings over time.
Is it difficult to install central heating yourself?
Yes. It’s complicated and required understanding of the boiler and the property. There are lots of legal regulations that you need to understand to ensure the system is safe and installed correctly.
Installing central heating requires skill and understanding due to connections to gas and water mains and an interconnected network of heating and hot water pipes. The complexity also increases with the project’s size and the extent of existing system replacement. Please be aware, only Gas Safe registered engineers are allowed to work with gas pipes and boilers.
Components:
- Boiler: Choose a boiler suitable for your property’s needs. Options include conventional, combi, system, biomass, and liquid petroleum gas boilers.
- Radiators: The number, style, and size of radiators affect installation complexity and cost.
- Control System: Options range from smart thermostats to traditional heating controls, impacting system efficiency and cost.
- Additional Parts: Depending on the boiler type, you may need filters, thermostats, cleaning solutions, hot water pipes, etc.
- Tools: Ensure you have the necessary tools for installation.
Installation Steps:
- Step 1: Create a map of the new system, considering boiler placement and radiator positioning.
- Step 2: Install radiators, ensuring proper valve installation and maintenance space.
- Step 3: Lay pipes connecting radiators to the boiler, using copper piping recommended.
- Step 4: Set up the control system following manufacturer instructions.
- Step 5: Fit the boiler, turning off hot water and gas during installation. A gas-safe registered engineer must handle the gas connection.
- Step 6: Commission the system by flooding it with water, activating the heating pump, and balancing the radiators.
