STL Heating & Energy

ST installed a new boiler in my house about 5 weeks ago. However the boiler has failed to produce hot water on two occasions. I am old age pensioner and I desperatlly require hot water. I left the hot water on all of Monday evening and all day of yesterday. Late yesterday evening it did eventually produce hot water. I phoned your company yesterday to report the fault. An engineer called back and left a message on my answer phone saying he would call again; but he did not. Although your company installed a Intergas boiler I had earlier expressed a preference foe the Worcester Bosch boiler I saw this mistake when I inspected the installation when the fitter had finished his work. I am asking you to replace the Intergas boiler with A WORCESTER BOSCH. Can you see to this as soon as possible, this will avoid me having to take further action. Yours faithfully J J Templeman
