The Unica i28 is a condensing combi boiler that is designed to provide excellent energy-efficiency under a lengthy manufacturer’s warranty. Manufactured to be compact in size, it could be an ideal choice for smaller homes that are tight on space.

Typically set up to serve homes with 2 or 3 bedrooms and one bathroom, the Unica i28 is a modern unit that is designed to deliver the central heating you need and manufactured to help lower energy wastage by reducing its own power output when appropriate.

Product description

As an A rated boiler with an efficiency rating of 98 per cent, the Unica i28 could be a suitable unit to power the central heating in a small to medium sized home with low to average hot-water requirements.

It has intuitive controls that make it easy to manage your hot-water supply and heating around the house, so you may be able to minimise energy wastage. The modulation ratio of the Unica i28 is a class-leading 10:1, which means that it could reduce its own power down to just 10%of its full capacity. Doing so when it identifies that your home doesn’t need as much heat could potentially help you reduce energy wastage and lower your energy bills**.

The unit is also manufactured to be easy to maintain thanks to the front-mounted heat exchanger; such features are designed to make the Unica 28i an ideal heating solution for the modern home.
