Legacy products and support
We built it. We still support it.

Looking for a manual?
Every manual and datasheet we published is still available from the product's page. If you can't find the product, or the unit has no badge, send us a photo of the unit and its serial label through the contact form and we'll identify it.
Need a service, a repair or a spare?
Annual servicing, breakdown visits, reconditioning and spares for all of these products come from the same engineers who built them. Spares are in the Heatweb store; visits are booked through the contact page or on 0345 241 1441.
Still running one of these units?
We hold the drawings, settings and spare-part knowledge for every product we built.
