FAQs
Hot Water Cylinder Questions
What's the difference between a direct, indirect and unvented cylinder?
A direct cylinder heats water using its own immersion heater, an indirect cylinder is heated by your boiler or heat pump, and an unvented cylinder is a sealed, mains-pressure system that doesn’t need a header tank. Our engineers can talk you through which type suits your home and how your current setup works.
How do I know if my cylinder needs repairing or replacing?
This depends on the type of fault, the age of the cylinder, and how it’s performing overall. Minor issues can often be repaired, but if the cylinder is old or the fault is significant, replacement may be the more reliable and cost-effective option. We’ll always give you an honest recommendation.
Can you install a hot water cylinder alongside a heat pump?
Yes, we install heat pump cylinders as part of new heat pump systems or as an upgrade to an existing setup, making sure everything is sized and fitted correctly for efficient performance.
What are signs my hot water cylinder is faulty?
Common signs include reduced hot water pressure, water that isn’t heating properly, leaks around the cylinder, or unusual noises. If you notice any of these, it’s worth having it checked before the issue develops further.
How long does a cylinder replacement take?
Most cylinder replacements can be completed within a day, though this can vary depending on the type of cylinder and any additional pipework or adjustments needed. We’ll confirm timing when we assess the job.
