Biasi system boilers are often installed in bigger residences and are intended for use in closed heating systems. Biasi system boilers may cost anywhere between £1,000 and £2,500.

Biasi Advance Combi Boiler

Efficiency and dependability

Efficiency and dependability were the two main considerations in the design of the Advance combi boiler. This combi, although being small and powerful, can produce up to 13.3 litres of rapid hot water per minute.

A high-quality, single-coil heat exchanger made of stainless steel that is both incredibly durable and effective has been created by Biasi. The single coil oval section prevents dirt and debris buildup by allowing the system water to circulate freely through the heat exchanger.

Perfect Old Boiler Replacement

This combi is therefore the ideal option for replacing an old boiler. With this series, ease of installation and use is obvious thanks to Biasi’s addition of a visible pressure gauge, straightforward controls, and an optional switchable mechanical clock.

Smart Controls

Adding a variety of smart controls will allow you to further increase home comfort while lowering your gas bills. This Advance has built-in weather compensation; by adding a quick, low-cost temperature probe, you can enable the boiler to automatically respond to the outside temperature, providing you with a boost when you need it and saving you money when you don’t. A 25KW, 30KW, and 35KW version of the Advance series is offered.


In accordance with the terms and conditions outlined in our Biasi warranty section, the Advance series is backed by a 5-year warranty.

The Advance Plus 7 Combi Boiler

High-end technology

The Advance Plus 7 is from a line of intelligent gas boilers made by Biasi and is their most recent offering. All models come with cutting-edge quad processor technology, which greatly increases their reliability and performance. Since Biasi constantly places a premium on safety, every contemporary boiler has some sort of lock-out device in case the gas supply is compromised or faulty.

Safety lockout mode

With the Advance Plus, however, the boiler detects when this occurs and the gas supply resumes and automatically releases the safety lockout without the assistance of a person. To easily regulate the temps of your heating and hot water, Biasi have given this range a simple up/down setting. A 24 hour mechanical clock that fits neatly into the control pad on the front of the device is an optional and simple to use


The Advance Plus Combi is covered by a 7-year warranty.

Biasi System boilers

A system boiler combines the greatest features of a combi boiler with a regular boiler. System boilers feature an in-built pump that allows them to respond rapidly and give hot water to several outputs at the same time.

Biasi’s system boiler range has outputs from 16kW to 30kW.

The Advance Biasi System Boiler

Energy efficient

The Advance System Boiler by Biasi is an 89% efficient condensing boiler. How much energy is lost during the process of producing heat and hot water determines a boiler’s efficiency rating. The boiler’s efficiency increases with its energy rating. The A-Rated Advance System Boiler will help you reduce your carbon footprint and save money on your energy costs.

Compatible with a range of heating controls for increased efficiency and comfort

All Advance System Boilers are compatible with a range of heating controls, such as thermostats, room sensors, and programmable timers, which allow you to manage your heating system efficiently and effectively.


A 5-year waranty is included with this boiler, giving you piece of mind in the unusual event that the boiler has a problem.

The Advance Plus 7 System by Biasi

Hot Water Cylinder

The Biasi Advance Plus 7 System is also equipped with a hot water cylinder, which provides a large storage capacity for hot water. This allows you to have a constant supply of hot water, even during periods of high demand. The cylinder is also well-insulated to help reduce heat loss and improve the efficiency of the system.

Easy to Install

In addition to these features, the Biasi Advance Plus 7 System is compact and easy to install, making it a great option for homes with limited space. It is also highly efficient, which can help to lower your energy bills and reduce your carbon footprint. The boiler is designed for quiet operation and features a digital control and display for convenient use.


A 7-year warranty is included with the Advance Plus 7 Biasi System Boiler.

Biasi Regular boilers

A regular boiler will be helpful if you live in a home with many bathrooms and a high demand for hot water. You may run the kitchen tap and the shower at the same time without losing hot water to either one since they can supply hot water to numerous outlets simultaneously.

A regular boiler, the Biasi Advance OV comes in three sizes: 15kW, 18kW, and 24kW.

The Biasi Advance OV

Simple Installation

The Advance OV boiler family was created to replace widely used conventional open vented boilers, with an emphasis on efficiency and dependability while maintaining the characteristics that make installation simple. The Advance OV preserves a small footprint casing and the flexibility to be integrated into conventional fully pumped S and Y plan systems while being compact and powerful.

Single Coil Heat Exchanger

Similar to its combi and system family members, the Advance OV boiler has a single coil heat exchanger that is incredibly reliable and effective. In order to reduce dirt and debris buildup, the heat exchanger’s single coil, oval portions enable system water to circulate freely through them. This makes the Advance the ideal option for replacing an outdated open vented boiler with a contemporary state-of-the-art boiler.

Built-In Weather Compensation

The Advance has built-in weather compensation; by adding a quick, low-cost temperature probe (optional), you can enable the boiler to automatically respond to changes in the outside temperature, providing you with a boost when you need it and saving you money when you don’t.


The Advance OV is equipped with a 5 year warranty.
