Several things could be making your hot water lukewarm. If you have a cylinder, the thermostat on the cylinder itself might be set too low or faulty. For combi boilers, it could be an issue with the boiler. Sometimes, especially in winter, the incoming water is much colder, and your system struggles to heat it quickly enough. Our engineers can help find the exact cause and get your hot water running properly again, often on the same day.

It's really important for customers with unvented hot water cylinders to have a professional service every 12 months. These systems operate under high pressure, and an annual check by a G3 qualified engineer (like us!) is vital for safety and to keep it running efficiently. This service ensures safety devices are working correctly and can prevent bigger problems down the line.

Think of it like this: a traditional vented cylinder usually has a cold water tank in the loft and relies on gravity, so your hot water pressure might be okay but not amazing. An unvented cylinder, on the other hand, takes water directly from the mains, so you get high-pressure hot water – great for powerful showers! Unvented systems don't need a loft tank, which can free up space. Our team can look at your current setup and help you find the right solution if you're considering an upgrade.

Strange noises like gurgling, banging, or kettling from your hot water cylinder, or any sign of a leak, mean it's time to call a professional engineer. Leaks, even small ones, can cause damage and might point to a problem with a valve or the cylinder itself. Noises can indicate scale build-up or pressure issues. Don't wait for it to get worse; let us take a look and repair it safely.

Yes, you absolutely do. Working on unvented hot water cylinders requires a specific qualification called G3. This is because they are pressurised systems and need to be handled correctly to be safe. Our engineers at Response Boiler Repair Liverpool are G3 registered, meaning we have the right training and expertise to install, service, and repair your unvented cylinder safely and legally. It's always best to check an engineer's qualifications.

A good quality hot water cylinder, whether vented or unvented, can last for many years, sometimes 10-15 years or even longer if well-maintained. Regular servicing helps prolong its life. Signs that your cylinder might be nearing the end of its working life include frequent problems, leaks, or if it's struggling to provide enough hot water. We can offer solutions if you think it's time for a replacement.

Many of our customers upgrade to unvented systems for the fantastic hot water pressure – it can really make a difference to your showers and bath-filling times. They also often free up space because you don't need a cold water storage tank in the loft. Plus, they can be more efficient as they heat water directly from the mains when you need it (or store it at mains pressure).
