FAQ

What is a "power flush" and does my central heating system need one?

A power flush removes any sludge and debris accumulated over the years by pumping chemicals around your central heating system under pressure. We always recommend that a power flush be undertaken as a preventative measure before a new boiler is fitted to maximise the efficiency of your central heating system and to comply with the manufacturer’s warranty. Flushing an old system will also increase the efficiency of the system and save you money in the long term.

Why do my radiators have cold areas?

If your radiator is cold at the bottom and hot on the top, this usually indicates a sludge build up in the bottom of the radiator. To remedy this problem we recommend you seek professional advice to identify the cause of the sludge first. This problem is generally resolved by power flushing the system to eliminate unwanted debris.

If your radiator is cold at the top and hot at the bottom, this generally indicates that air is trapped at the top of your radiator. Bleeding the radiators to release the air is a simple procedure, which may resolve the problem quickly. However, if this problem persists we do recommend you have your central heating checked.

How often do boilers need to be serviced?

In order to ensure your boiler is working safely and at optimum performance, most boiler manufacturers recommend an annual boiler service. Servicing your boiler is an important step to help prevent an unexpected breakdown.

Why do I not get enough hot water from my combination boiler?

Older models of combination boilers may not be as effective as the newer generation, where improvements in efficiency and ability have been made. In addition, a build-up of scale may cause the flow rate of an older combination boiler to deteriorate. That being said, in many cases we can help you achieve a worthwhile improvement in hot water flow.
