Hollin Primary School, Rochdale

Client: Brookdale Gas Ltd


Our client for this project was the contractor Brookdale Gas Ltd who carried out the main installation of this heating scheme serving the school buildings.


The project was for the design, supply and installation of a twin wall insulated stainless steel chimney system serving two new Hoval UltraGas 300 boiler units.


A common horizontal header arrangement was installed linking the outlets of the two appliances and traversing the plantroom at high level. After turning vertical the chimney system would rise 3.0m through the roof cladding to terminate with a open cone top. Connections to the respective appliances were made using a 250mm inside diameter single wall Condensor system with the header and vertical riser made using 300mm inside diameter twin-wall Therminox TI system comprising a stainless steel 316L inner - stainless steel outer - 32mm mineral wool (130kg/m3) insulated annulus. Our team spent just two days on site to complete the chimney installation ready for handover.

Chimney System:

Both Condensor and Therminox TI chimney systems are CE marked, manufactured and designed as suitable for use with any type of gas, oil and wood-burning atmospheric appliances, but are perfect for all condensing appliances with a maximum operating temperature of 200°C.
