Unvented Hot Water Cylinder Installation in Whitefield in Bolton & Greater Manchester

Yes, absolutely. Because these systems store water under pressure and at high temperatures, they can be dangerous if fitted incorrectly. UK law requires that anyone working on these systems must have a G3 qualification to ensure all safety valves and discharge pipes are installed correctly.

In most cases, yes. Unvented cylinders can work with most modern system boilers and even some older heat-only boilers. However, if you are looking to save the most money on your bills, pairing a new cylinder with an Air Source Heat Pump is often the smartest long-term move. We can assess your current boiler and let you know the best path forward.

Before we start any work, we carry out a pressure and flow test on your incoming water main. For an unvented system to work well, we generally look for a minimum of 1.5 bar of pressure. If your pressure is lower than that, don't worry—we can discuss options like accumulator tanks or pump-assisted systems to give you the performance you want.

To keep your warranty valid and make sure the safety valves are working correctly, you should have your cylinder serviced once a year. We provide full servicing across Whitefield and Bury to check the internal air gap or expansion vessel and clear any debris from the filters.
