FAQs About Excavation Services in London
Excavation is typically required when drainage pipes are severely damaged, collapsed or beyond repair. If a CCTV drain survey identifies a significant issue that cannot be resolved using non-invasive methods such as drain lining, excavation may be the only option to access and replace the affected section.
Can I use an unvented cylinder with any boiler?
Unvented cylinders work well with system or regular boilers, but not with combi boilers, as combi systems don’t require a hot water cylinder. Your installer will help determine the best setup based on your current system and hot water needs.
How much maintenance does an unvented system require?
Unvented cylinders should be serviced annually by a qualified engineer to ensure they remain safe and efficient. Regular maintenance helps prevent issues and extends the lifespan of the system.
