All Vokera boilers are required to be serviced annually to ensure continued efficiency and safety. Failing to service your boiler annually will not only affect the safety of yourself and others around you but also affect your boiler warranty/guarantee’s validation.

An experienced and professionally qualified engineer will service your boiler in accordance with the following schedule:

  • Check the boilers performance, flue and ventilation
  • Visually check all components for water leaks
  • Full inspection for damaged or worn components
  • Visually inspect burner and heat exchanger for deposits and clean accordingly
  • Visually check for satisfactory ignition
  • Check the flame failure device, check and adjust burner pressure
  • Fully check the boiler operation and controls
  • Check the expansion vessel and reset pressure accordingly
  • Carry out a flue gas combustion analysis


Over time, your boiler’s efficiency will naturally decline slightly, however, annual servicing and regular maintenance will ensure that your boiler is working as efficiently as possible.

Combi boilers are often the preferred boiler choice because they remove the need for any additional hot water cylinders or cold water tanks as the water heater and the central heating is built into one single unit.

Thanks to its high-efficiency rating of 89.6% and an ErP A-rating for both central heating and hot water, this boiler could not only help you to reduce your energy bills but could also help reduce your carbon footprint.

The Vokera Unica ‘i’ range has 3 combi boilers with outputs of 28kW, 32kW, and 36kW. The i28 is the least powerful combi boiler in its range, however, with an output of 28kW, it is still powerful enough to heat small to medium-sized properties with up to 15 radiators and 1-2 bathrooms. However, if you feel that your home has a higher demand for central heating and hot water, the Unica i32 or i36 may be more suitable. 

Thanks to its high-efficiency rating of 89.6% and an ErP A-rating for both central heating and hot water, this boiler could not only help you to reduce your energy bills but could also help reduce your carbon footprint.

Combi boilers are often the preferred boiler choice because they remove the need for any additional hot water cylinders or cold water tanks as the water heater and the central heating is built into one single unit.

The Vokera Unica i32 sits in the middle of the range when it comes to output reach, with an output of 32kW. This boiler is ideal for homes with a higher demand for central heating and hot water, and up to 20 radiators and 2 bathrooms. If your home requires a higher output rating, Vokera has designed the i36 for properties that require more power, meanwhile, the i28 is available for homes with lesser demand. 

Despite its power, the boiler unit itself has been designed to be compact and lightweight allowing for installation to be simple and straightforward. Thanks to its size, this boiler unit can be fitted neatly into a standard kitchen cupboard, out of sight, out of mind.

With an efficiency rating of 89.2% and an ErP A-rating for both heating and hot water, the Vokera Unica i36 combi boiler could potentially help you to reduce your carbon footprint and also help to lower your energy costs.

Combi boilers are often the preferred boiler choice because they remove the need for any additional hot water tanks or cold water cylinders as the water heater and the central heating is built in one single unit. This means that hot water is available on demand.

As mentioned, the Unica i36 combi boiler is the most powerful of its range when it comes to output, however, many smaller homes would not have this demand for central heating and hot water. In this case, the Unica i28 or i32 combi boilers may be a better choice for your home.
