At the end of this post, you’ll have everything you need to choose wisely with the tools.
What Is a Hot Water Cylinder, and Why Do You Need One?
A hot water cylinder is a tank-type storage cylinder that’s used to heat and store hot water for your property. Unlike a combi boiler, which provides on-demand heating to the tap, a hot water cylinder will store the water and keep it warm. They are therefore great for households that use large amounts of water. For instance, whether you’re busy taking multiple showers or drawing a bath, with a decent cylinder, you never need to worry about running out of hot water. With a hot water cylinder, you will also have hot water at hand when you need it, even at peak times of the day. Consequently, this system is convenient for large homes or those with a lot of water usage.
Types of Hot Water Cylinders
1. Vented Hot Water Cylinders
Vented systems are linked to a cold water storage cistern (usually in your loft). The water is drawn into the cylinder by gravity and becomes heated. These tanks are inexpensive but require a considerable amount of space for the tank.
Key Features:
- It is designed simply by using a few components.
- Lower initial cost.
- Needs a loft tank (won’t be suitable for all homes).
2. Unvented Hot Water Cylinders
Open-vented systems are open to the atmosphere and are connected to a second tank, so they tend to have lower pressure; unvented ones utilize water straight from the mains, providing higher pressure and doing away with the additional tank, and so on. Great for contemporary homes that have that little bit less loft space.
Key Features:
- Delivers high water pressure.
- Reduces space requirements.
- Upfront cost is high and must be professionally installed.

Key Components Explained with a Hot Water Cylinder Diagram
Knowing the components of a hot water cylinder will help you choose the right one to suit your requirements. Here is a model answer of the different things you will find in a hot water cylinder diagram.
- Cold Water Feed: A system that feeds cold water to be heated.
- Heating Element/Coil—This is the part that heats the water inside the cylinder. It is heated electrically, with an electric immersion heater or with a boiler linked to the system.
- Thermostat: Keeps water at your desired temperature, preserving energy.
- Pressure Relief Valve (on unvented systems): Avoids excessive pressure in the cylinder and is a safety feature.
What Size Hot Water Cylinder Do You Need?
Selecting the right size is important for both efficiency and economy. A tank that’s too small will run out of hot water, while a tank that’s too large will be inefficient and waste energy. So take care to get the correct size, and you’ll never have to worry about these problems. Here’s a simple guide to sizing based on house size and demand:
- For 1-2 people, a 120-150 L tank should be enough.
- For 3-4 people, a 180-200 L cylinder will do the job.
- For a bigger family (5+ people): Go for a 250L+ cylinder.
Tip: Consider future usage. If you’re in a gut renovation of a bathroom or adding to a growing family, go up one size.
Materials to Consider
Hot water cylinders typically use stainless steel or copper. Here’s how the two compare:
Stainless Steel
- More corrosion-resistant.
- Longer lifespan.
- Lightweight and durable.
Copper
- Offers fast heat conduction.
- Less expensive upfront.
- Suitable for low pressure.
Energy Efficiency and TCO (Total Cost of Ownership)
There is more to this than simple energy savings; investment in energy-efficient measures leads to lower bills and less impact on the environment. Seek out cylinders that have excellent heat retention, a high level of insulation, and efficiency certification to industry standards.
Hint—which can also save you money: when fitted in conjunction with a modern hot water cylinder, adding thermostatic valves can also maximize your energy use.
