Just a short note to express our thanks for the work done to our heating system. We have had heating engineers and plumbers various into the house in the 10 or so years we have been here. The usual “flushing” the system, “flushing” the radiators concerned were tried over that time but to no avail. Since Ben worked on the system a few weeks ago, we are very pleased to report that the conservatory radiator (which never seemed to warm up) is now working as it should.
