Understanding Unvented Hot Water Cylinders
Unvented hot water cylinders are a modern alternative to traditional vented systems. Unlike vented cylinders, which rely on a cold water storage tank in the loft, unvented cylinders are directly connected to the mains water supply. This design allows for higher water pressure, improved efficiency, and a more streamlined installation process, particularly in homes with limited loft space.
Unvented systems provide hot water to multiple outlets simultaneously without a significant drop in pressure, making them ideal for properties with multiple bathrooms or high hot water demand.
Benefits of Installing Unvented Hot Water Cylinders
At Philip Cheeseman & Sons, we guide our clients through every stage of the installation process, ensuring that they fully understand the advantages of choosing this system. Key benefits include:
- High Water Pressure: Direct connection to the mains supply allows for strong, consistent flow rates to showers, baths, and taps.
- No Need for a Cold Water Storage Tank: This frees up valuable loft space and simplifies the overall plumbing setup.
- Improved Water Hygiene: With no standing water in loft tanks, there is a reduced risk of contamination or stagnation.
- Enhanced Energy Efficiency: Many unvented cylinders are compatible with solar thermal systems and heat pumps, supporting energy-saving initiatives.
- Flexible Installation Locations: The system can be installed in utility rooms, airing cupboards, or garages, making it highly versatile.
Our Installation Process
Our approach to the installation of unvented hot water cylinders in Melksham is defined by thorough planning, adherence to regulations, and the highest standards of workmanship. Each installation includes:
1. Initial Consultation and Site Survey
We begin with an on-site assessment to evaluate your current hot water system, water pressure, space availability, and hot water demands. This ensures the correct system is specified for your property.
2. Selection of the Right Cylinder
We supply cylinders from trusted manufacturers known for their performance and reliability. Depending on your needs, we recommend either indirect models (heated by a boiler) or direct models (heated by an immersion heater).
3. Professional Installation by Qualified Engineers
All installations are carried out by our Gas Safe Registered and G3-qualified engineers. We strictly comply with Building Regulations Part G3, ensuring all safety and pressure control components are correctly installed and tested.
4. System Testing and Commissioning

5. Ongoing Maintenance and Servicing
To maintain safety and efficiency, we recommend annual servicing of your unvented cylinder. Our maintenance services help identify potential issues early, ensuring long-term reliability and compliance with warranty terms.
