When it comes to providing reliable hot water in your home, a hot water cylinder is one of the most efficient and cost-effective solutions. Whether you’re upgrading an old system or installing a new one, choosing the right cylinder ensures you’ll always have a steady supply of hot water for baths, showers, and household tasks.
At TradePlumbing, we stock a wide range of hot water cylinders from trusted UK brands, designed to suit different property sizes and energy systems. With our high-quality options and expert advice, you can find the perfect solution for your home.
What Is a Hot Water Cylinder?
A hot water cylinder is a storage tank that holds hot water, ready for use whenever you need it. Unlike combi boilers that heat water on demand, cylinders store heated water, making them ideal for homes where multiple taps and showers may be in use at the same time.
Types of Hot Water Cylinders
Choosing the right type is crucial for efficiency and performance. Here are the most common options:
Vented Hot Water Cylinders
- Connected to a cold water tank (usually in the loft).
- Relies on gravity for water pressure.
- Ideal for traditional heating systems.
Unvented Hot Water Cylinders
- Mains-fed for strong water pressure.
- No need for a loft tank, saving space.
- Perfect for modern homes and multiple bathrooms.
Indirect Cylinders
- Heated via an external boiler system.
- Compatible with gas or oil boilers.
Direct Cylinders
- Uses an electric immersion heater to heat water.
- Great for properties without a boiler.
At TradePlumbing, we stock all these options so that you can choose the best fit for your home and heating system.
