Top 8 Best Hot Water Cylinders for UK Homes in 2025
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.
