Biasi Boilers Boiler Efficiency Rating

Biasi - Boiler Efficiency Rating

Biasi is named after its Italian founder, Leopold Biasi who started the company in 1938 and then began manufacturing residential boilers in the 1940s. After all these years, they’re still very much an Italian company but opened Biasi UK in 1996 and now sell boilers to over 40 countries around the world.

What are the Main Boiler Ranges Available from Biasi?

With a range of efficient, cost effective and dependable boilers, the Combi and System units they manufacture have multiple outputs available so there’s likely to be one for your home.

Advance Combi Boiler

Designed to be efficient and reliable, this compact Combi is very powerful as it can deliver instant hot water at up to 13.3 litres per minute. Included are a visible pressure gauge, simplistic controls and an optional mechanical clock for ease of operation and installation.

The Advance range is available outputs of 25KW, 30KW and 35KW to match the demands of a variety of households. Featuring a 5 year guarantee that covers parts and labour, you’re well covered with this range.

Advance Plus

The Advance Plus 7 range is our latest intelligent gas boiler, all models are equipped with cutting edge quad processor technology, making them extremely reliable and efficient.

With safety at the forefront for Biasi, these boilers all include lock out systems incase of a fault with the gas supply. When the gas supply returns to normal the boiler will know and resume normal function without anyone having to get involved. Even when the cold months set in, these boilers will be well protected thanks to built-in frost protection to stop the boiler freezing over.

With the range available in outputs of 25kw, 30kw and 35kw, the heating and hot water demands of most households will be met. You’ll be well covered too as this range comes with a 7 year warranty.


This is Biasi’s most advanced range of domestic boilers. You’ll be kept fully in the loop by the boiler about the temperature of water entering it and of the hot water leaving it. They’re also able to get itself going again should there be a safety cut out, like when there’s a disruption to the gas supply.

There’s good news if you have a solar cylinder too, if there’s ever a day when there isn’t enough solar gain, Inovia boilers will increase the temperature of the water that leaves the cylinder.

Boilers in this range come with a variety of outputs including 25kw, 30kw and 35kw, so the majority of domestic settings are covered. They also feature a 5 year warranty to keep you covered well after installation.
