Frequently Asked Questions
Find answers to common questions about our services and process.
The right choice depends on your water pressure needs, loft or plantroom space and whether you want mains-pressure hot water. Vented cylinders suit properties with a cold tank, while unvented cylinders give higher flow and are better for multiple bathrooms. We carry out a site survey and recommend the most appropriate system.
