In today’s homes, where saving energy is important, having a good hot water cylinder isn’t just a nice thing—it’s something you need. If you’re having issues like not enough water pressure or running out of hot water too fast, upgrading your system can really help. But with so many choices like vented hot water cylinders, unvented cylinders, and regular hot water tanks, it’s hard to pick the right one.
This guide explains the top 5 reasons you should think about upgrading your hot water system now—and which type might work best for your home.
1. Better Energy Efficiency and Lower Bills
Older hot water tanks can use a lot of energy and add up on your bills. Many of them don’t have good insulation and lose heat quickly, which means your boiler or immersion heater has to work harder.
Newer hot water cylinders, especially those with high-quality foam insulation, keep heat for longer, which uses less energy. Unvented cylinders also have built-in expansion vessels, so you don’t need extra tanks, and there’s less heat loss.
Tip: Choose cylinders that meet ERP energy standards and have quick reheat times for the best results.
2. Better Water Pressure Around the House
If your system uses gravity-fed water (common in older vented setups), you might notice weak water pressure, especially upstairs. Switching to an unvented hot water cylinder connects your system directly to the mains water supply.
This gives you strong water pressure all over your home, so you get better showers and faster filling baths without needing a pump.
Extra Benefit: Mains-fed systems also help keep water temperature steady, even when several taps are open.
3. Space-Saving and Flexible Installation Options
Space is a big plus in many UK homes, but it can be hard to get. Traditional vented hot water cylinders need a cold water tank in the loft, which takes up space and makes using the attic tricky. It also adds more work during installation.
Modern unvented cylinders don’t need a loft tank. They are sealed and work directly from the mains. This means you can free up your attic and place the cylinder in more convenient spots, like a utility room or even a kitchen cupboard.
Tip: If you’re doing a renovation, an unvented system can make your layout easier and cut down on the amount of pipework you need.
4. Better Hygiene and Water Quality
You might not know this, but water stored in a loft tank can get dirty from dust, insects, or if the tank isn’t well insulated. Unvented cylinders bring water directly from the mains, giving you fresh and clean water each time.
Because they are sealed and pressurized, there’s no risk of the water sitting still or getting contaminated from outside. Some people still use vented cylinders, which work with gravity, especially if their home has old pipes or they’re on a budget.
Even so, newer vented cylinders are safer with better valves, insulation, and materials that resist rust.
Health Win: Switching to a sealed system stops bacteria from growing in your water supply.
5. Future-Proofing with Renewable Energy
If you’re looking ahead, new hot water cylinders are made to work with eco-friendly energy sources. Solar panels and air source heat pumps are now being paired with both vented and unvented cylinders for a more sustainable heating option.
Choosing a cylinder with two coils or one that works with solar power now can help you add green technology later without the need for big plumbing changes.
Eco Advantage: A solar-friendly cylinder can help cut down on gas or electric heating use, which lowers your carbon footprint.
Which Type of Hot Water Cylinder Should You Choose?
- Vented Hot Water Cylinder
- Best for homes with existing gravity-fed systems
- More affordable and simple in design
- Requires a cold water storage tank
- Unvented Cylinder
- Ideal for modern properties and new builds
- Delivers high pressure and consistent flow
- No loft tank needed—saves space
Both types can be made from copper or stainless steel and come in a range of capacities to suit different household sizes.
