    Glow-Worm Essential Combi Boilers

    The Glow-Worm Essential Combi Boiler will set you back anything between £618.00 and £658.00, which includes VAT and excludes installation.

    Glow-Worm Essential Combi Boilers

    Simple and reliable, the Glow-Worm Essential Combi is a highly efficient combination boiler that comes in a choice of 24kW or 28kW outputs.

    It has fairly compact dimensions which measure 740mm (H) x 418mm (W) x 300mm (D) and is suited to small and medium-sized properties. This model is also ideal for homes where loft and storage space is limited because it doesn’t require a separate cold water tank or hot water storage cylinder.

    Essential Combi prices vary according to the heat output, typically from £618.00 to £658.00. When it comes to cover, you’ll be given a free 3-year parts and labour guarantee provided the boiler is fitted by a Glow-Worm Club Energy installer. For added peace of mind, you can choose to extend the warranty period for a fee.

    Boiler Energy Efficiency Credentials

    Glow-Worm’s Essential Combi features a modulating Grundfos pump – one of the most energy efficient pumps on the market that is known for achieving the highest possible energy savings. Of course, this means that the pump will play its part in saving you money on your fuel bills as well. You’ll also be pleased to know that the boiler comes with an 89.3% efficiency rating and is SEDBUK A rated for heating and hot water efficiency.

    Essential Combi Technology and Main Advantages

    This sleek model by Glow-Worm has a powerful aluminium heat exchanger, helping the boiler to perform to a high standard. It also has the impressive Grundfos pump we mentioned above, which helps to reduce energy use and save you money.

    The range includes two output sizes with different maximum hot water flow rates, which are as follows:

    • Essential 24kW Combi – 10.0 litres per minute
    • Essential 28kW Combi – 11.7 litres per minute

    By being a lightweight boiler, installation is quicker and easier so you should save some cash on fitting costs. The Essential Combi is easy to use and manage, thanks to the smart interface, bright LCD display and in-built analogue timer. This appliance is also compatible with Glow-Worm’s range of flues and intelligent accessories including the MiGo personal heating assistant control and wireless programmable room thermostat.

    Is the Glow-Worm Essential Combi the Right Boiler Type and Size for Your Home?

    Available in two outputs, the Essential Combi is suitable for small and medium properties – not large houses with higher heating and hot water demands. As a general rule, the 24kW unit is best for flats and smaller dwellings with 1 bathroom and up to 10 radiators, and the 28kW version is ideal for medium-sized homes with 1 bathroom and around 15 radiators. Having said that, this information won’t be accurate for every property, so you must consult with a Gas Safe engineer over your needs before you purchase this model.
