What Is a Mains Pressure Cylinder?
Also known as an unvented cylinder, a mains pressure cylinder delivers hot water directly from the cold mains, rather than relying on gravity and header tanks in the loft.
This means:
- More powerful showers
- Faster-filling baths
- Better flow to multiple taps at once
- No need for noisy pumps or extra storage tanks
- Hot water on demand throughout your property
Perfect for modern homes, large families, landlords, and property renovations.
Our Cylinder Services Include:
New Cylinder Installations – G3-qualified engineers
Cylinder Replacement – Swap old cylinders for new energy-efficient models
Annual Servicing – To meet legal and manufacturer warranty requirements
Troubleshooting and Repairs – Leaks, pressure issues, poor performance
System Upgrades – Combine with boilers, solar or heat pump systems
Commercial & Domestic Properties – Schools, offices, and large homes

We install market-leading brands, including Heatrae Sadia Megaflo, Gledhill, Joule, Telford, and Kingspan, and we’ll help you choose the right size and model for your property.
