I have heard of 'Power Flushing'. What is that?

Power flushing is a system deep clean of the ‘sludge’/’gunk’ that builds up over time in your heating system. The system flush clears out this ‘sludge’ making sure your radiators heat up properly and there are no cold spots.

This helps to increase the life of the boiler/heating system, thereby keeping heating bills down and reducing the risk of any boiler breakdowns.

The filter within the boiler is normally replaced during the ‘Power Flush’ as this filter is designed to capture most of the ‘sludge’.

At ATB Plumbing & Heating we only relace the filter if required and only use ‘Magna Clean Pro’, magnetic filters.

Are ATB engineers fully trained and 'Gas Safe' registered?

Yes,  we are fully trained in all the modern technological advances for our industry and, are on the ‘Gas Safe’ register ( No 624630)

Do you guarantee your work?

Yes, of course,  ATB Plumbing & Heating provides you with a 12-month guarantee against any faulty workmanship.
