Product Description

The Advance OV 18kW is a condensing regular gas boiler that has been designed and manufactured by Biasi and thanks to its compact size, is perfect for smaller homes.

Reliability and efficiency were in mind when Biasi put together their Advance OV range, which you can see by the 92% efficiency level and ErP A rating for heating. The 20.3 kW output is a good match for homes with 10-15 radiators.

Should an 18kW unit not be suitable for your home, then the Advance OV range also includes 15kW and 24kW models too. The 15kW output is perfect for smaller homes, with 1 bathroom, that have a low demand for heating and hot water, while the 24kW can meet the higher demands of homes with more than 1 bathroom. If a Regular boiler isn’t appropriate for your home then you’ll also be able to choose between System and Combi units too.

Biasi have made sure that the Advance OV range has plenty to offer, with one of the features including a single coil heat exchanger, that’s extremely robust and efficient. The single coil oval sections allow system water to flow freely through the heat exchanger, preventing the accumulation of dirt and debris. In addition, the Advance OV 18kW also features a built-in weather compensation, installing the optional inexpensive temperature probe too, will allow the boiler to automatically change with the temperature outside, helping to reduce your energy bills.

As a Regular boiler, the Advance OV 18kW heats your central heating system directly and also produces hot water to be stored in a cylinder. Due to the fact that you need a hot water cylinder, which is often fed by a cold water storage cistern located in the loft, Regular boilers aren’t recommended for smaller properties where space is limited.

A lengthy warranty period of 5 years gives you the confidence that you’re well covered by Biasi long after the installation.
