Our heating system used to be noisy, temperamental and would require frequent bleeding of radiator valves. It was either too hot or too cold. Now, thanks to Paul, it is now working as intended. It provides us with a warm, comfortable and quiet environment to live in. It also gives me peace of mind knowing that when it goes off, it will restart and tick over as smoothly as a Swiss watch.
