What is an unvented hot water cylinder?
Unvented cylinders are a modern hot water storage solution connected directly to your mains water supply.
Unlike vented systems, they do not require a cold water storage tank in the loft, which saves space and simplifies the setup.
These high-capacity hot water systems are ideal for homes and businesses in Dartford needing consistent pressure and performance, as they offer:
- Strong water pressure at all taps and showers
- Consistent hot water across multiple outlets
- Sleek, space-saving design
- Compatibility with air source heat pumps
Unvented systems are particularly ideal for larger homes, properties with multiple bathrooms, and all types of commercial premises in Dartford looking for reliable, high-capacity hot water.
What are the benefits of an unvented cylinder?
- Mains pressure hot water at all outlets
- No need for loft tanks – making them ideal for conversions or homes without loft space
- Faster bath filling and reliable hot showers
- High flow rates – no reduced pressure with multiple simultaneous users
- Good energy efficiency when paired with modern boilers or renewable systems
- Long service life, typically up to 25 years with proper maintenance

Dartford unvented cylinder installation FAQ
How long does an unvented cylinder installation take in Dartford?
Usually one day for replacements, and up to two days for new installations. However, times can vary depending on the complexity of the install.
We will provide an estimated time during our survey.
Do I need a boiler to have an unvented cylinder?
No – you can install a direct cylinder that works from electric immersions, and potentially an Economy 7 meter.
If I have a boiler, do I need a new one in order to install an unvented hot water cylinder?
No – unvented cylinders can usually be integrated with existing boilers.
Can unvented cylinders be used with combi boilers?
Yes, although this is not a common setup, as combi boilers heat water on demand and do not require a separate cylinder. However, some hybrid systems do exist.
Is annual unvented cylinder servicing required?
Yes, we strongly recommend annual servicing to maintain your cylinder’s safety devices, prevent breakdowns, and ensure continued compliance with the manufacturer’s warranty.
We offer annual servicing packages, where our engineers check the expansion vessel, pressure relief valve, and thermostat, and flush the system if needed.
