The Trentham Cornish Boiler

Horizontally mounted brick-set Trentham Cornish boilers were marketed by the firm for around thirty years; offering them to use in factories, especially for high buildings where there was a large head of water and a requirement for a large quantity of hot water. It was also marketed to gardeners where a large quantity of pipes required heating. They were also recommended as an alternative solution for supplying either heating or domestic hot water for larger residences.

The boilers were never manufactured by the firm; simply buying them in when required, either from Messrs. Robert Jenkins & Co., of Rotherham or latterly from Messrs. H. Coltman & Sons of Loughborough

The firm offered three basic models, patterns Nos. 1, 2 and 3. Pattern Nos. 1 and 2 were available either a welded or riveted form; pattern No. 3 was only available in a riveted form and specifically targeted for domestic use. Pattern No. 1 had an open end and 3¼in. waterway; pattern No. 2 had a checked end, with a 3¼ in. waterway; pattern No. 3 had an open end, a 6in. waterway and a detached front.

All three patterns were available with either cross tubes (riveted or welded) and/or waterway bridges, at additional cost.

Prices included a complete set of furnace fittings, such as fire bars, bearer bars, soot doors, damper and frames, etc. and carriage to the nearest railway station in England or Wales.

The firm is known to have sold only 12 Trentham boilers; the earliest in 1895 and the last in 1914. On five of those occasions they installed twin boilers, including one in a hospital.
