Central Heating Service FAQs

  • How much does a new central heating system cost?

    The size of your property also plays a role. For example, a two-bedroom bungalow may require radiators and installation costing around £4000, while the supply and installation of a gas boiler can cost between £2,000 and £3,800 on top of this. The complexity of installation further add to these costs. Therefore, a comprehensive understanding of these factors can help you budget more effectively, ensuring your home stays warm.

    Remember that selecting an appropriate boiler is like choosing the heart of your central heating system. It influences not only the cost of installation but also the efficiency of your heating system.

    Some factors to consider when choosing a boiler include:

    • The size of your home and the number of bathrooms
    • The level of energy efficiency you desire
    • The hot water demand in your home

    Combi boilers, for example, are efficient because they produce hot water only when needed, potentially leading to substantial energy savings. However, they may not be suitable for homes with high simultaneous hot water demands as they might cause a longer wait for hot water.

    If you have a larger home with multiple bathrooms, a system boiler could be a better choice due to their ability to provide a reliable supply of hot water from an external cylinder.

    Your property’s size has a considerable impact on the central heating installation costs. Larger homes require more radiators and a more powerful boiler. This means more extensive pipework, which increases the complexity and cost of installation. It’s not just about the number of radiators, but also their size. Proper radiator sizing is essential for home heating efficiency and is determined using a radiator sizing chart.

    Balancing installation costs and system demands also requires choosing the right hot water cylinder based on the property size and mains water pressure.

  • What are gas central heating system advantages?

    Gas heating systems are the workhorses of home heating, offering low consumption costs and a high level of operational reliability. They are among the cheapest heat generators available, reducing high initial investment costs for homeowners considering a new heating system.

    Furthermore, an efficient gas central heating system can significantly reduce your fuel bills. Thus, if your home has access to the gas grid, gas central heating systems might be a cost-effective and reliable choice.

  • What components are part of a central heating system?

    A complete central heating system includes:

    • A boiler
    • Pipework
    • Radiators
    • Hot water storage solutions

    These components work together to keep your home warm. They maintain the system’s condition and improve its efficiency.

    Understanding these key components can help you plan your central heating installation and manage your budget effectively, taking into account the central heating installation cost.

  • Which radiator choices can I pick from?

    Radiators bring warmth to each corner of your home. They come in various types and sizes, and their choice and installation can significantly influence the efficiency and cost of your heating system.

    Radiator valves are available in three variants:

    1. Manual valves: These valves require manual adjustment to control the temperature of each radiator.
    2. Thermostatic valves: These valves have a built-in thermostat that automatically adjusts the temperature based on the desired setting.
    3. Smart valves: These valves can be controlled remotely through a smartphone app, allowing for personalized heating settings throughout a space.

    By choosing the right type of radiator and valve for your needs, you can ensure efficient and cost-effective heating in your home.

    Thermostatic radiator valves (TRVs) help control room temperature by shutting off water flow to the radiator when the desired temperature is reached, promoting energy efficiency and comfort. The cost for manual radiator valves ranges from £10 to £30 each, whereas thermostatic radiator valves are priced between £20 to £50, and smart radiator valves typically cost between £40 to £80.

  • Do I need a hot water cylinder?

    These come in two primary types for central heating systems: vented and unvented, costing between £2000-£2900 and £2400-£3,300 respectively. In installations with conventional or system boilers, a separate hot water cylinder is necessary, with vented cylinders connected to a storage tank and unvented providing mains pressure water.

    It’s essential to balance these costs with your system requirements and installation

  • Do I have to change my heating controls?

    Heating controls assist in managing temperature, timing, and energy consumption. Smart thermostats use learning algorithms and occupancy detection to adjust heating automatically, which can save an estimated 10%-15% annually on energy costs. They offer:

    • Remote access, enabling temperature adjustments from anywhere via internet-connected devices
    • Cutting down on unnecessary energy use
    • Contributing to lower energy bills

    Traditional thermostats, on the other hand, are more affordable and simpler to operate, although they lack the advanced energy-saving characteristics of smart thermostats.

    Equipping yourself with a smart thermostat offers several benefits:

    • It is akin to hiring a personal assistant for your heating system.
    • It can be integrated with existing central heating systems to provide more accurate and efficient temperature management.
    • It can be controlled remotely, offering convenience and ensuring your home is always at the perfect temperature upon arrival.

    Moreover, smart thermostats can integrate with other smart home systems, allowing for a more connected and automated living environment. Some systems also include multiple remote sensors for different rooms or zones, providing tailored heating or cooling based on the needs of each area.

  • Difference between a manual and programmable room thermostat?

    While smart thermostats are the advanced brains of a heating system, manual and programmable thermostats are the tried and true workhorses. Manual digital thermostats provide more accuracy than mechanical ones, enabling precise temperature control within +/-1°F or +/-0.5 degrees Celsius. Programmable thermostats, on the other hand, are well-suited for those with predictable schedules, automatically adjusting home heating in their absence. They may feature 7-day programming, energy-saving modes, and user-friendly touch-screen displays, adding convenience and potential energy savings.

    Some programmable thermostats are even designed for DIY installation, making them a balance between advanced features and ease of use.

  • How can central heating installations lower energy bills?

    Despite the potentially high cost of a central heating system installation, its long-term benefits warrant consideration. Here are some of the benefits:

    • A new combi boiler should be around 90% efficient, offering increased energy efficiency compared to many older boilers.
    • Condensing combi boilers pre-heat water using waste flue heat, enhancing their efficiency to 90% or better.
    • Modern condensing system boilers with a minimum energy efficiency of 92% can provide annual savings of up to £630 by replacing less efficient models.

    Furthermore, smart thermostats and programmable room thermostats can help users make informed heating and cooling decisions with detailed energy consumption reports, potentially reducing energy bills. In fact, upgrading your heating system could potentially reduce your energy bills by up to 30%.

  • What to expect on Installation day

    On the day of installation, the engineer will lay pipes beneath the floor to connect the new boiler to radiators and faucets. The heating system might not require draining during the boiler change, however, this should be verified with the installer.

    While the installation process can be messy, installers are expected to clean up after the work is completed, maintaining the cleanliness of your home.

    The time required for a central heating installation can vary from a few days to several weeks depending on the size of the project and the efficiency of the installation team.

  • Can you install your own central heating system?

    It’s possible to install radiators and pipework if you’re comfortable with DIY, but a certified heating engineer must install or repair the boiler due to safety concerns.

  • How much does it cost to install central heating in London?

    The average cost of installing central heating in London ranges between £5,500 and £10,000, covering the boiler, radiators, pipework, heating controls, and potentially a hot water storage cylinder and tanks.

  • Which areas do you cover?

    We install central heating systems in London, Surrey and Kent.
