For many homeowners, upgrading offers better water pressure, improved energy efficiency, and valuable space-saving benefits. If you’re renovating or modernising your home, an unvented system is often a smart investment.
How do I know if I have a blocked drain?
Common signs of a blocked drain include:
- Water draining slowly from sinks, toilets or showers
- Unpleasant odours coming from drains
- Gurgling sounds in pipework
- Rising water levels in toilets
- Overflowing or backed up drains outside
If you notice any of these signs, contact London Drainage Facilities Ltd immediately for a professional inspection and clearance.
Can I use an unvented cylinder with any boiler?
Unvented cylinders work well with system or regular boilers, but not with combi boilers, as combi systems don’t require a hot water cylinder. Your installer will help determine the best setup based on your current system and hot water needs.
How much maintenance does an unvented system require?
Unvented cylinders should be serviced annually by a qualified engineer to ensure they remain safe and efficient. Regular maintenance helps prevent issues and extends the lifespan of the system.
Do I need good water pressure to install an unvented cylinder?
Yes, because unvented cylinders rely on mains pressure, it’s important to have a strong and consistent water supply. A qualified installer will assess your pressure levels during the initial survey to ensure suitability.
Are unvented systems safe?
Yes, unvented hot water cylinders are very safe when installed and maintained correctly. They are fitted with multiple safety features such as pressure relief valves, thermostats, and expansion vessels to prevent overpressure and overheating.
What is an unvented hot water cylinder?
An unvented hot water cylinder is a sealed system that connects directly to the mains water supply. It delivers hot water at high pressure without the need for a separate cold water tank in the loft, making it a more modern and space-efficient solution.
