Unvented Cylinders
An unvented hot water cylinder is an increasingly popular choice for homeowners who want mains-pressure hot water throughout their property without the need for a separate cold water tank in the loft. As demand for high-performance domestic hot water systems grows, more households across Central Scotland are making the switch to unvented cylinders, and Heatsafe Heating has the qualifications and experience to fit them properly and safely.
Fitting an unvented cylinder is specialist work that must be carried out by a qualified engineer holding the relevant G3 Unvented Hot Water Regulations competency. Our team is fully qualified and ensures every installation meets current building regulations and manufacturer requirements, giving you complete confidence in the system from day one.
How an Unvented Cylinder Works
Unlike traditional vented cylinders, which rely on a cold water tank positioned at a high point in the property to create pressure, an unvented cylinder connects directly to the mains cold water supply. This means hot water is delivered at mains pressure, which is a significant improvement for households that have struggled with poor shower pressure or slow-filling baths due to a gravity-fed system.
Because there is no need for a header tank, unvented cylinders also free up valuable space, particularly in loft conversions and properties where every square metre counts. Modern unvented cylinders are also well insulated, meaning water retains its heat for longer and the system operates more efficiently overall. For larger households with multiple bathrooms and a high daily hot water demand, an unvented cylinder is particularly well-suited to meeting that demand consistently.
Is an Unvented Cylinder Right for You?
If you are on a gravity-fed hot water system and finding that pressure is inconsistent, particularly when multiple outlets are in use at the same time, an unvented cylinder is likely to make a noticeable improvement to everyday comfort. It is also an excellent option for new builds, full bathroom refurbishments and any project where you want to remove the cold water tank from the loft entirely.
