Ferroli Boilers: Compare Efficiency, Warranty & Price

Ferroli takes pride in its in-house production which is great news for customers. Why? Because it shows that the company retains complete control, not only over the quality of its products but also for delivery and after sales care as well.

Most Ferroli boilers run on natural gas but they also have a range of electric boilers too. No matter which type of boiler you plan to have installed, it’s important to check the output rating, efficiency and warranty period.

  • Output rating: A boiler with a suitable output rating for the heating and hot water demands of your home is vital. Measured in kilowatts (kW) An output rating that’s too low will result in the boiler failing to meet demand; go too high and you’ll notice a rise in your energy bills.
  • Efficiency: A new boiler should help to lower your energy bills and the efficiency will tell you how much fuel the boiler is able to convert into usable energy. Ferroli gas boilers sit at around the 90% mark for efficiency, making them highly efficient. While their electric boilers are almost 100% efficient (99.5%).
  • Warranty: It’s good to know that you’re covered in the unlikely event that your boiler should run into a fault after the installation and this is where the warranty comes in. Ferroli boilers come with warranty periods of 2-10 years to ensure that you’re well covered.
  • Price: Ferroli are one of the more budget-friendly boiler manufacturers with gas and electric boilers available for under £1,000.

It’s worth comparing a few boilers when considering a boiler replacement to help find the most suitable model for the heating and hot water demands of your home. You can compare up to 4 different boilers with our Boiler Comparison Tool – simply hit the ‘add boiler’ symbol to add a boiler. We recommend including your current boiler alongside those you’re considering as a replacement.

Ferroli combi boilers

Ferroli combi boilers are a cost-effective choice and, because they only have four moving parts, they are easy to install and simple to maintain too. The 24-27 kW Ferroli combi boilers are ideal for homes with 1 bathroom and around 10 radiators. If you have more radiators than that, then the higher outputs of 28-34 kW will meet the demands of homes with up to 15 radiators.

Compare Ferroli system boilers

System boilers directly heat the central heating system while storing domestic hot water in a cylinder. This means that in addition to a Ferroli system boiler, you’ll also need a hot water cylinder elsewhere in your home (typically found in an airing cupboard).

Compare Ferroli electric boilers

Ferroli electric boilers are a great option for small homes and flats where it isn’t possible for a gas boiler to be installed. Electric boilers are able to reach such high levels of efficiency as they don’t burn fossil fuels to generate energy. Instead, the electricity is used as a power source to generate heat which in turns warms up the water for central heating and domestic hot water.

The electric boilers manufactured by Ferroli are available in 4 different outputrs, with each being better suited to heating up a different number of radiators – 6 kW (4 radiators), 7.5 kW model (5 radiators), 9 kW model (6 radiators) and 12kW boiler (8 radiators).

Benefits of Ferroli combi boilers

You’ll benefit from low energy bills without having to make any compromises on performance if you choose a Ferroli combi boiler.

If space is your issue – and you want to enjoy energy efficient heating and hot water, a Ferroli combi boiler is what you need.

  • Choose from different kW outputs to match your domestic usage patterns
  • Enjoy maximised energy efficiency as well as heat and hot water on demand
  • Save space in your loft or home by choosing a compact but hard-working combi boiler

Ferroli Modena 32S HE System Gas BoilerThe system boiler range is Ferroli’s alternative to the widely used combi boiler.

Also an energy efficient option, a modern system boiler has no need of a bulky cold water tank in the loft – however it does make use of a hot water cistern with is the main difference between a combi and a system boiler.

The hot water tank usually sits out of the way in an airing cupboard and keeps a constant supply of hot water ready for you to use whenever you need it.

It’s quite common for homeowners with more than one bath or shower room to decide on system boiler, but it’s also fine if you just have one.

  • Great choice if energy efficiency is a key priority for you
  • Standard warranty of 5-years can be increased to 7 or 10 if preferred
  • Range of outputs offered; choose to meet your specific domestic needs
  • Recommended by the Energy Saving Trust
