OEM and bespoke: your own range, built by World Heat
Two routes: for domestic heat pump manufacturers, and for commercial equipment partners. We design and build cylinders, vessels and packaged plant to your specification, in our own factories in Dukinfield, Greater Manchester.
Domestic heat pump manufacturers
A cylinder or pre-plumbed package matched to your heat pump, your controls and your installation instructions, in your branding. Your installers get one package to fit, with your name on it.
- Unvented and heat pump cylinders built to your heat pump and controls specification
- Pre-plumbed and wired in our factory and delivered ready to fit
- Sold as one package under your own brand
Commercial equipment partners
Plant manufacturers, contractors and specifiers: calorifiers, buffer vessels and packaged plant built to your drawings, tested before dispatch, and repeated to the same design whenever you need more.
- Vessels from 10 to 10,000 litres, with the sizes, connections, coils and insulation on your drawing
- Cylinder, buffer, controls and pipework built and tested as one unit, so the site team connects it rather than builds it
- Repeat batches to the approved design
