What will be the most important development for condensing boilers?

The trend for more compact boilers capable of delivering higher outputs will continue, as the number of retrofit and refurbishment projects increases.

One of the most important developments will be that these boilers compliment emerging LZC technology, such as heat pumps, solar thermal and mini-CHP (all available from Baxi Commercial), to minimise dependence on fossil fuels and continue to reduce carbon emissions in the UK.

What features distinguish your products from others in the market?

A comprehensive and high quality product range, dedicated nationwide sales force, extensive technical back-up and an innovative 10-year warranty* make Potterton Commercial and its condensing boilers the logical choice.
