Top 8 Best Hot Water Cylinders for UK Homes in 2025

/0 Comments/in /by

Finding the right hot water cylinder is key to ensuring your home always has a steady, efficient, and reliable hot water supply. At TradePlumbing, we offer a complete range of cylinders designed to meet every household’s needs, from traditional vented systems to modern unvented models and renewable-friendly options. In this guide, we highlight the top types of hot water cylinders you can choose for your home in 2025.

1. Unvented Hot Water Cylinders

An unvented hot water cylinder connects directly to your mains water supply. This means you’ll enjoy strong, consistent water pressure for showers, baths, and taps across your home. Made from durable stainless steel, they resist corrosion and minimise heat loss. They’re perfect for busy households and properties with multiple bathrooms.

2. Vented Hot Water Cylinders

A vented hot water cylinder uses a cold water storage tank in the loft to feed your system. This setup is tried and tested, making it a reliable choice for homes with low mains pressure. Vented cylinders are easy to maintain, cost-effective to install, and can be a great option for traditional heating systems.

3. Solar Hot Water Cylinders

For households aiming to reduce energy bills and embrace renewable energy, solar hot water cylinders are a smart choice. These cylinders work with solar thermal panels to capture and store energy from the sun. Most models come with twin coils, allowing you to integrate both solar and conventional heating sources.

4. Combination Cylinders

If you’re short on space, a combination cylinder could be ideal. These compact units combine a hot water cylinder and cold water storage into one tank, eliminating the need for a separate loft tank. They’re perfect for flats, small houses, or areas with limited storage space.

5. Direct Hot Water Cylinders

A direct hot water cylinder is heated by an internal immersion heater. This makes them an excellent choice for homes without a boiler or gas supply. They’re quick to install, easy to maintain, and provide reliable hot water whenever you need it.

6. Indirect Hot Water Cylinders

An indirect hot water cylinder is heated by an external boiler, with an immersion heater often included as a backup. This design ensures rapid water heating and high efficiency. It’s the go-to option for homes with central heating systems, offering fast recovery times and consistent performance.

7. Buffer Tanks

Buffer tanks store extra heated water to help balance the performance of heating systems. They’re especially useful in homes with underfloor heating or multiple heat sources, ensuring steady water temperatures and reducing strain on your main system.

8. Thermal Storage & PulsaCoil Hot Water Cylinders

These advanced hot water cylinders store water at high temperatures and blend it with cold water for safe delivery. PulsaCoil systems are popular in apartments because they provide mains-pressure hot water without the need for a discharge pipe. They’re also low-maintenance and efficient.

Choosing the Right Cylinder for Your Home

When selecting a hot water cylinder, consider your water pressure, heating system, household size, and energy goals.

  • Choose unvented cylinders for powerful mains-pressure performance.
  • Opt for vented cylinders if you have a traditional gravity-fed setup.
  • Select solar cylinders to save on energy costs and reduce your carbon footprint.
  • Pick combination cylinders for compact spaces.

Top 7 Benefits of Choosing a Vented Hot Water Cylinder

/0 Comments/in /by

Worldwide, having hot water in your house is of great importance, and so it is critical to select an effective, reliable, and long-lasting hot water cylinder. In the UK, a hot water cylinder is vented, a commonly used type for many decades.

Newer systems like the unvented cylinder have their place; however, even vented systems have a place, particularly around homes with the usual setups. At TradePlumbing, we sell a full array of vented hot water cylinders, tried and tested brands such as Telford, made to give top-quality performance in millions of homes. These are the 7 best reasons why you should pick a vented hot water cylinder for your property.

1. Proven Reliability

A gravity-fed, hot water cylinder utilizes a cold-water header tank (typically in the loft), and is topped up by the movement of the water (gravity). The design has been around since time immemorial, where British homes have employed the use of the design. The ease of the system will imply fewer parts of the mechanism, which risks breaking down.

A vented solution is safe, should you require a reliable source of heating that you can depend on year after year.

2. Simpler Installation

Vented systems can be installed readily than pressurised systems. They are not subject to the rigorous safety valves and receptacles that pressure does, as they operate at atmospheric pressure. In older homes with a header tank in place already, it can be an easy job to install or replace a vented cylinder.

This gives them an appeal when it comes to doing so without throwing a headache down the line or when replacing a current indoor gravity-fed installation.

3. Less Maintenance Costs

One of the greatest benefits of a vented hot water cylinder is maintenance. Given that it does not require high-pressure components, not as many parts need servicing or replacing down the road. Vented systems are common among most UK plumbers, and repairs and service are therefore normally faster and cheaper than unvented solutions.

4. Excellent Match to Older Buildings

If you live in an older home with existing pipework designed for low-pressure systems, a vented hot water cylinder is often the best match. High-pressure systems may require expensive pipework upgrades, while vented systems work seamlessly with the existing infrastructure.

They also suit homes with low mains water pressure as they do not depend on it to perform.

5. CMD Water Heaters

Numerous vented hot water cylinders are either direct or indirect heating:

  • A direct cylinder contains an immersion heater within the tank and systems that heat the water directly.
  • Indirect cylinders connect to an external heat source like a boiler or solar thermal system via a heat exchanger coil.

This flexibility means you can choose a model that best suits your energy setup, whether you’re using a traditional boiler, renewable energy, or a hybrid approach.

6. Long Lifespan

Durable vented cylinders like the Telford Standard Vented Copper Cylinders, which one can find at the TradePlumbing stores, are made with quality material that will last decades. Copper models can provide due to their antibacterial action, and superb heat conductivity, or stainless steel alternatives corrode longer than ever before.

The advantage of this durability is years of savings and many years of hot water.

7. Cheaper than High-Pressure Systems

Vented hot water cylinders tend to be cheaper, overall, than unvented ones, both to buy in the first place and to maintain in the future. Vented systems offer fantastic value-for-money to those homeowners on a budget, or others who simply want a proven, cost-effective answer. They are, of course, reliable too.

The Selection of the Appropriate Vented Hot Water Cylinder
