Questions from installers and merchants
Will a World Heat cylinder fit the same space?+
Usually, at the same capacity — but heights and connection positions differ between manufacturers, so compare the dimensions in the table above with the cylinder you’re replacing. Ask us for a drawing to check the connection positions. If space is tight, a slimline or bespoke cylinder can be built to fit.
Can you match a specific model?+
Yes. Send us the model or product code from the old cylinder’s label (a photo is ideal) and we’ll recommend the closest match, or build one to the same dimensions.
Does it come with everything I need?+
Our unvented cylinders are supplied with an unvented kit. Tell us the heat source and any controls you need and we’ll confirm what’s included in your quote.
What about heat pump jobs?+
Our Climacyl heat pump cylinders have coils sized for low-temperature heat pump flow, from 120 to 500 litres. We also build pre-plumbed heat pump packages.
I’m a merchant — can I stock your range?+
Talk to our sales team about the sizes your branch sells most and we’ll talk you through the options.
