Featuring high-efficiency condensing technology, the Ferroli Energy Top is suitable for heating only systems but can provide hot water when used with a mains water supply.

As a result, you don’t need to have a cold water tank or hot water cylinder installed in order for this appliance to provide you with heating and hot water. Measuring in at 945mm (H) x 445mm (W) x 440mm (D), this wall mounted boiler can be used alone or multiple units can be linked to allow for cascading operation.

Available in three outputs of 60kW, 80kW and 125kW, the boiler is a practical solution for large domestic dwellings and small commercial properties. It comes with a standard 2-year warranty and will cost you anything between £2,133.00 and £3,426.56.

Boiler Energy Efficiency Credentials

Boasting an efficiency level of 98%, the Ferroli Energy Top is an A-rated condensing boiler with a 4-star energy rating. It’s also an environmentally friendly model and has been rated 5 stars for its very low NOx and CO2 emissions. This appliance comes with an air-gas metal fibre burner with variable speed fan and pneumatic gas valve to achieve efficiency levels of over 107% and allow for a range of modulation which can extend from 11 to 100% of rated output.

Energy Top Technology and Main Advantages

Although configured for operation on natural gas, the Ferroli Energy Top can be converted to LPG (liquefied petroleum gas) with a conversion kit. In addition to the air-gas premix metal fibre burner we mentioned above, the boiler also features a high-efficiency aluminium silica alloy heat exchanger with 31mm waterways to reduce corrosion and eliminate hot spots.

Independent external switching of controls helps to maximise efficiency, and the included heat exchanger allows for a maximum temperature difference across the flow and return. The boiler also comes with a hot surface ignition with independent flame detection probe, a low water pressure protection switch and independent internal 6 bar safety valve.

Perhaps one of the most impressive things about the Energy Top is that it enables you to link together a number of units without any need for additional controls. We should also mention that this boiler is suitable for pressurised systems and open vented systems with a minimum of 1 bar availability.

Is the Energy Top the Right Boiler Type and Size for Your Home?

With a 60kW, 80kW and 125kW model available in the Energy Top range, the boiler is perfect for large homes with more than one bathroom and small commercial installations. Since it doesn’t require a tank or cylinder and the all of the parts are accessible from the front, this appliance is a great option if you want to keep the unit in a tight space. To ensure you pick the right boiler and output for your home, we recommend you always consult with a Gas Safe engineer over your heating and hot water needs.
