Unvented hot water cylindershave been increasingly installed in UK households since the 1980s, gaining significant popularity over time. Unlike vented hot water cylinders, they eliminate the need for a cold water tank, making them ideal for space-constrained environments. These sealed cylinders are directly supplied from the cold mains, ensuring a constant flow of water. The high-pressure entry of water from the mains enhances the reliability and consistency of flow rates from unvented cylinders.
What is the installation cost of an unvented hot water cylinder in Penarth?
As previously mentioned, opting for an unvented hot water cylinder can incur higher costs compared to a vented system due to the necessity of installing additional safety features. However, this increased investment is essential to guarantee your safety and ensure the seamless operation of your system.
In short, an unvented hot water cylinder can cost between £400 to £1600+, depending on different factors such as the size, brand, if you already have a cylinder installed and if you need to move your system.
An unvented hot water cylinder can be a great investment if installed properly and with the required safety measures. They can last for years and provide instant hot water to your taps and showers.

What are the advantages of an unvented hot water cylinder?
Space Saving: Unvented cylinders do not require a cold water tank in the loft, making them ideal for homes with limited space. This frees up valuable space for other purposes.
Continuous Hot Water: Direct connection to the mains ensures a constant supply of hot water at mains pressure, eliminating the need for a gravity-fed system. This means you can enjoy hot water at multiple outlets simultaneously without a drop in pressure.
Improved Flow Rates: Unvented systems typically provide better flow rates compared to vented systems, ensuring a stronger and more consistent flow of hot water from taps and showers.
Flexible Installation: Unvented cylinders can be sited anywhere in the property as they do not rely on gravity for water distribution. This allows for greater flexibility in installation and design.
Quiet Operation: With no cold water tank filling up, unvented systems operate quietly, providing a more peaceful environment in your home.
Reduced Risk of Freezing Pipes: The absence of a cold water tank in the loft reduces the risk of pipes freezing in cold weather, minimizing the chances of damage and inconvenience.
High Efficiency: Unvented cylinders are often highly efficient, as they can be easily integrated with modern heating systems and renewable energy sources, such as solar panels or heat pumps.
Overall, unvented hot water cylinders offer convenience, efficiency, and reliability, making them a popular choice for modern homes.
Is an unvented hot water cylinder the right choice?
Unvented hot water cylinders are an excellent choice for residential properties, particularly those with limited space, as they eliminate the need for a cold water tank. Their high pressure capability makes them suitable for homes with multiple bathrooms, allowing for simultaneous use of taps and showers without a noticeable drop in water flow.
In recent years, they have become increasingly popular and are often the preferred option for both new construction projects and renovation projects. Their ability to provide high water pressure makes them ideal for luxurious bathrooms featuring multi-jet showers or jetted baths.
Moreover, unvented cylinders are well-suited for environments with high hot water demand, such as hotels, offices, schools, and leisure centers. With a large unvented cylinder or multiple units, hotels can ensure a continuous supply of hot water to all rooms, even during peak usage periods.
unvented hot water cylinder offer an environmentally friendly alternative for hot water provision, with the potential to be powered by solar panels. The heat from solar panels can be transferred to the cylinder via a coil installed at the base of the specially designed vessel. Although the initial cost of unvented hot water cylinder replacement is around £1400, their energy efficiency and green credentials make them a cost-effective and sustainable option in the long run.
How does an unvented hot water cylinder work?
The hot water cylinder is directly fed from the incoming mains water supply, which keeps the water under constant pressure and ready to be used. To heat the water within an unvented hot water system there are two different methods.
In a directly heated model, the cold mains water is heated by an immersion heater built into the cylinder. Conversely, in an indirectly heated model, an external source such as a gas boiler or solar panels heats the water.
When hot water is required at a tap or appliance, the pressure from the incoming cold water pushes the hot water out of the cylinder. This hot water is then carried through an outlet pipe to its intended destination.
These systems are equipped with pressure and temperature relief equipments. The aim of these tools is to vent the cylinder in case it overheats or in the event that the internal pressure gets too great. This safety feature is designed to minimise the chances of failing equipments or, in serious cases, the risk of explosion.
Do unvented hot water cylinders need servicing?
It is essential to keep your system serviced and well-maintained. Regular servicing can prolong the lifespan of your cylinder and ensure that it is working efficiently and without troubles. It can also ensure that it is safe to operate and pose no threat to your safety. Your system should be checked once a year by a qualified technician. Reach out to Let’s Heat if you need your system checked and well serviced.

FAQ’s
How long does an unvented cylinder keep water hot?
Based on information provided by most hot water cylinder manufacturers, it is estimated that a fully filled hot water cylinder will experience a heat loss of approximately 1 kWh to 2.5 kWh per day. With this heat loss rate, a hot water cylinder should be able to retain hot water for approximately one to two days before needing to be reheated.
How long does underfloor heating take to warm up?
A floor-mounted underfloor heating system has a quick heating response, rapidly warming up your home. On the other hand, an underfloor heating system embedded within a screed may take longer to reach the desired temperature. However, once heated, it has excellent heat retention properties, keeping the floor warm for an extended period.
Furthermore, underfloor heating systems, including those embedded within a screed, often come with programmable settings. This allows for precise heat control, enabling you to set specific temperature levels and schedules according to your preferences and energy-saving requirements.
Is underfloor heating safe and good for your health?
Underfloor heating is indeed a healthier and safer alternative to traditional radiators. By concealing exposed hot surfaces, it minimizes the risk of accidental burns and creates a safer environment, particularly for households with children or pets. Additionally, underfloor heating eliminates dust traps, as there are no protruding surfaces or hard-to-reach areas for dust to accumulate. This contributes to improved indoor air quality and reduces potential allergens in the living space.
