Del Sol provides an updated heating system for Abraham Moon

A modern heating system for a leading woollen mill with traditional roots dating back to 1837

Background to Abraham Moon

Abraham Moon & Sons was founded in 1837 in Guiseley, West Yorkshire. In the early days, Abraham Moon would sell yarn to families or pay weavers to create fabrics from his yarn before selling the finished goods to the local community. After years of building strong relationships with the community, the business expanded.

In 1868, he had a three-storey mill built in Guiseley. The Yorkshire location was perfect for wool production, with soft water ideal for scouring fleece and a newly built railway to Leeds running directly behind the mill.

In 1902, the original mill burnt to the ground but was quickly replaced with a larger, single-storey mill. It also became a fully vertical operation, meaning every stage of production – from processing raw fleece and dyeing the yarn to weaving and finishing the fabric – took place on-site.

This is the same mill that continues to operate today. It remains one of the few fully vertical woollen mills still in use in Britain, with most modern wool production now spread across multiple facilities.

The heating system at Abraham Moon

Just before Christmas 2022, Del Sol received a call from Abraham Moon making an enquiry about updating the heating system. Based in the factory premises rebuilt in 1902, the mill was operating an ageing heating system fed from a central boiler.

The heating system consisted of a collection of inefficient steam-heated blowers that were in urgent need of replacement.

The project was exactly the kind of challenge we enjoy at Del Sol.

In January 2023, we visited Abraham Moon and carried out a full tour of the building and its existing steam heating system. The company was planning to replace the old steam boiler in the Dye House with a new modern steam generator and a standby boiler. This meant we needed to find an alternative way of heating the production areas that relied on the existing steam heaters.
