Zanussi Boilers: Compare Efficiency, Warranty & Price

Zanussi is a household name when it comes to quality, innovation and contemporary design in household appliances, and Zanussi boilers are no exception. They manufacture gas-fired combi and system boilers that are highly efficient and come with warranties of up to 10 years.

  • Output rating: The size of the boiler is arguably the most essential thing to get right when comparing boilers. By size we don’t mean the physical dimensions rather the power the boiler is able to deliver. Simply put, the higher the output rating then the more capable the boiler will be of meeting higher demands for heating and hot water.
  • Efficiency: Zanussi boilers burn natural gas to produce central heating and hot water. When burning this fuel, some waste gases are produced. And this means that not all of the fuel is converted into usable energy. Fortunately, Zanussi boilers perform efficiently and this is reflected in the seasonal space heating efficiency rating of 92-93%.
  • Warranty: A warranty is a promise from the manufacturer that they will cover the parts and/or labour should a fault arise as a result of the manufacturing process. Zanussi Ultra boilers come with the option of a lengthy 10 year warranty.
  • Price: Zanussi don’t make the prices of their boilers publically available but the typical price of a new boiler can range from £500 to over £2,000.

With our Boiler Comparison Tool, you can compare the key specifications of up to 4 different boilers. To add a new boiler to the comparison, simply hit the ‘add boiler’ symbol. We recommend always including your existing boiler as part of any comparisons that you make.
