    The Ferroli Econcept 51A Boiler has a typical price tag of £1,874.66, which includes VAT and excludes the cost of installation.

    Ferroli Econcept 51A boiler

    Designed and manufactured by Ferroli, the Econcept 51A is a wall mounted modulating condensing boiler that has a 5-star rating for low emissions.

    The boiler features cutting-edge technology and can operate on either natural gas or LPG (liquefied petroleum gas) depending on your requirements. It also has a high output of 50kW, measures in at 720mm (H) x 630mm (W) x 380mm (D) and is fully equipped with a ceramic premix burner.

    As the Econcept 51A can be installed as a singular unit or as part of a multi-boiler cascade setup (up to five units can be connected), this model is ideal for large domestic dwellings and small commercial properties. You can expect to pay around £1,874.66 for the boiler, which comes with a standard 1-year warranty.

    Boiler Energy Efficiency Credentials

    The Ferroli Econcept 51A is 98% efficient and 4-star rated for efficiency. Thanks to its very low NOx emissions, the boiler is rated 5 stars for low emissions and widely compliant with class 5 EN 297 – the best performing class. To ensure user comfort and energy savings throughout the year, this appliance can be installed with an optional external probe which activates a ‘Sliding Temperature’ mode to control heating system temperatures according to outside weather conditions.

    Econcept 51A Technology and Main Advantages

    This highly energy efficient boiler by Ferroli features a premix ceramic reverse micro flame burner to eliminate the effects of thermal expansion of the burners and deliver extremely low emissions. It has its own efficient aluminium silica alloy heat exchanger with 16mm waterways to prevent the risk of hot spots and debris-related corrosion.

    An inbuilt boiler pump has been included, or you can choose an optional inbuilt DHWS (domestic hot water system) pump if you wish – with the DHWS control performed by the on-board controller. The boiler is also available in cascade operation (maximum of five boilers) and there is no need for additional controls to allow for this.

    Ferroli’s Econcept 51A has a low water pressure protection switch, hot surface ignition with independent flame detection probe and internal 6 bar safety valve. It also features microprocessor controls and a multi-function display panel to enable you to manage heating temperatures with ease. What’s more, efficiency can be maximised with independent external switching of controls.

    Is the Econcept 51A the Right Boiler Type and Size for Your Home?

    Developed for modular application, the Econcept 51A is ideal for small commercial sites and large domestic properties with multiple bathrooms. Since this model has cascading boiler capability it is best suited to larger buildings that require a heat generator that can reach a very high output. As this is a large, powerful appliance, you must ask a Gas Safe engineer to assess your property and needs to make sure you select the right sized boiler. If you choose a boiler that is too big for your home or business premises, your energy bills are likely to rise.

    Our Honest Opinion of the Ferroli Econcept 51A

    Able to operate alone or in a cascade, the Ferroli Econcept 51A is a simple to use boiler for heating, as well as hot water when an optional hot water tank is installed. If you require a lot of power, you can combine up to five single 50kW boilers for a total output of up to 250kW. And since each unit includes electronic programming, optimum operation from 11kW to 250kW is guaranteed.

    We like that the boiler features premix ceramic burner technology to absorb thermal expansion and deliver low emissions, and includes a special heat exchanger to increase efficiency and performance reliability. It’s also a flexible boiler that can be used on a pressurised system or open vented system where a minimum of 1 bar is available.

    It certainly seems to be a reliable, high-efficiency appliance that really packs a punch, however, we think it should come with a longer standard warranty to boost the level of consumer confidence.

    Advice on Boiler Quotes and Gas Safe Engineers

    Buying a boiler can be costly, so we recommend you shop around for the best deal on both the Ferroli Econcept 51A and the installation work. We also suggest you get in touch with national and local installers and ask for a fixed price quote so that you never have to pay any hidden charges. To ensure safe and legal installation, always make sure your chosen engineer is Gas Safe registered by viewing the details on their ID card or checking the official list at the Gas Safe Register website.
