    Central heating system installation explained


    Central heating installation is the process of setting up a system that efficiently heats your entire home or property. It works by distributing warm air or hot water throughout your house, ensuring a comfortable and cosy environment during the colder months.

    The heating system typically consists of a boiler, pipes, radiators, and a control system.

    A new central heating system usually includes:

    A central heating boiler: This is the heart of the system, responsible for heating the water or air that will be distributed throughout your property. This can be a gas or electric boiler, an air conditioner, a heating unit, or a heat pump.

    Radiators or underfloor heating: These components release the heat into your rooms, ensuring a comfortable indoor temperature.

    Pipes: These copper pipes connect the boiler to the radiators, allowing the hot water or air to circulate.

    A control system: This enables you to adjust and regulate the temperature and timing of your central heating. This new system also helps you control your gas bills.


    What types of central heating boilers are there?


    There are several types of central heating boilers, including combi boiler/s, conventional boilers, system boilers, condensing boilers, and electric boilers. In new builds, there are normally heating units. Each has its advantages and is suitable for different property types and heating requirements.

    When it comes to a heat pump, this can be a ground source or an air source of a heat pump.

    Step 1: Assess your heating needs. Before buying a new boiler, consider the size of your property, the number of occupants, and your heating and hot water requirements. This will help you determine the right type and capacity of boiler for your home.

    Step 2: Find a reputable supplier or heating engineer. Look for established suppliers or heating engineers who are Gas Safe registered. They can provide expert advice and guide you through the process of choosing the right boiler for your needs.

    Step 3: Get a detailed quote. Contact your chosen supplier or engineer and request a detailed quote for the new boiler and its installation costs. The quote should outline all the costs involved, including the price of the boiler, replacement charges, and any additional services.

    Step 4: Schedule the installation. Once you have received the quote and are satisfied with the offer, schedule a convenient time for the installation to take place. A qualified engineer will then install the boiler, ensuring it meets all safety and regulatory standards.

    How much does the installation of a new central heating system cost?


    The cost of installing a new heating system can vary depending on factors such as the type of boiler installed, the number of radiators, and the complexity of the installation.

    Combi Boiler System


    This is very popular and also the most energy-efficient system. These systems don’t require a hot water cylinder in the airing cupboard. This gas boiler heats the water only when you need it, which makes it very efficient. It is also heating your radiators when you turn up the room thermostat.

    With this central heating system:
    You save a lot of space and money on your bills.
    You will have modern heating controls.
    Your boiler is heating the water only when you need it.
    The main supply feeds the boiler, and you can have powerful pressure in the shower.
    This boiler is recommended to serve one bathroom.



    System Boiler

    Our installer helps you choose the best option for you.

    You can have a storage tank installed.

    The cold water will be fed from the main, thus producing powerful hot water for the bathrooms.

    You can have multiple bathrooms.

    You can use more than one shower at the same time.

    Conventional boiler system

    In this scenario, we install a regular boiler for you together with a storage tank. Usually, we replace or upgrade these types of central heating systems.
    This is a heat-only boiler, which will heat the radiators and also the cold water that is stored in the storage tank. This is ideal for homes, where are low pressure and high water demand.

    The Conventional Boiler Advantages:
    Because you have an immersion heater in the storage tank, you have backup hot water all the time. If your boiler breaks down, the immersion heater can be used.
    Multiple people can use the bathroom at the same time.
    Perfect where there is low water pressure.
