Common Myths About Unvented Water Cylinders Debunked

Unvented water cylinders have become increasingly popular in UK homes. However, they’re often misunderstood. Misconceptions about these systems can keep homeowners from enjoying their benefits and drive up both their costs and inconvenience. Let’s debunk some of the most common myths and set the record straight.

Myth 1: They’re unsafe.

Some people worry about the high pressure in unvented systems, thinking it might cause them to explode. Modern unvented water cylinders come with multiple safety features, like pressure relief valves and thermostatic controls, to ensure they operate safely. When installed and maintained by a qualified engineer, they’re as safe as any other water heating system.

Myth 2: They’re expensive to run.

While the initial cost of installation is higher than a vented system, unvented cylinders are incredibly efficient. They deliver hot water directly from the mains, meaning you don’t lose heat through a cold-water storage tank. Over time, the efficiency can save you money on your energy bills.

Myth 3: They’re only for large homes.

Think unvented systems are only for mansions? Think again. Compact models can fit in smaller spaces, making them ideal for flats or homes where space is at a premium. That’s one of the qualities that make these cylinders so popular. You can install them almost anywhere, from the basement to under the stairs, if there’s enough space and a water connection.

Myth 4: They’re noisy.

Some homeowners believe that unvented systems are louder than their vented counterparts because of the higher water pressure. However, when installed correctly, unvented water cylinders operate quietly. Any unusual noise is typically a sign of an issue, such as trapped air or sediment buildup, which can be resolved with maintenance. If you’re experiencing noisy operation from your current unvented cylinder, get in touch with us to schedule maintenance.

Myth 5: They require constant maintenance.

It’s easy to assume that unvented systems, with their advanced technology, demand constant upkeep. They require only an annual service, just like any other heating system. Regular inspections by a qualified engineer ensure everything runs safely and efficiently, but they don’t need constant attention. At EasyFlow, our engineers are all G3-qualified so they can maintain your unvented cylinder properly.

Myth 6: You’ll lose water pressure during peak times.

A common misconception is that unvented systems can’t handle the demands of multiple outlets being used simultaneously. In fact, because they’re connected directly to the mains supply, they provide strong and consistent water pressure, even when you’re running a shower upstairs and filling the kitchen sink downstairs.

Understanding the facts about unvented water cylinders can help you make the right choice for your home. These systems are safe, efficient, and a great investment for reliable hot water.
