Vokèra Unica i boiler series

The Unica i range from Vokera consists of a set of energy-efficient condensing combi boilers that are designed to provide homeowners with a way of heating their homes both effectively and efficiently.

The modulation ratio of 10:1 could put your central heating system at the top of its game by automatically reducing its power output to as little as 10% when it detects that full power isn’t necessary.





Boilers in the Vokèra Unica i Boiler series

Suitable for a range of homes, the Unica i series aims to provide versatility and efficiency. Here’s a rundown of the units in the range.


Unica i28

The lowest power output of the range comes in the i28, which makes it typically suitable for small to medium homes with 1 or 2 bathrooms.


Unica i32

The Unica i32 has a power input of 25kW for central heating and 32kW for hot water, which gives it a flow rate of 13.1 litres per minute. This boiler is typically suitable for homes with 3-4 bedrooms and 1-2 bathrooms.


Unica i36

At 384mm, the i36 has slightly more depth than the i28 and i32 (compared to 358mm); this allows for a flow rate of up to 14.7 litres per minute. This boiler could be suitable for a home with 4 or more bedrooms and 2 or more bathrooms.

Product description

Vokèra prioritises ease of use in its Unica i range and this shows in the user-friendly controls and the typically quick and easy installation process. Whether you’re a small family in a small home or a large family in a large one with multiple bathrooms, Vokera has a boiler for you in its Unica i range – all you need to think about are the power outputs, flow rates and dimensions associated with each unit, and our advisors are happy to help out with this. The i36 will support high demands for water but will take up slightly more room, whilst the i28 will provide the same kind of efficiency in a more compact unit with a lower output.

Each model is designed to heat your home and provide hot-water with the kind of effectiveness you require for comfort.
