The contractors arrived on time, used sheets to cover the floor, worked very neatly tidying up as they went along and answered any questions which were bothering us. The job was completed within 3.5 hours. The end result was just as we had been told by the representative and contractors, we are very, very pleased we had this job done going from one large hot water tank and another cold tank which took up so much room to just a small unit in the corner. The contractors checked everything before they left and explained the workings of the water heater. Very very pleased customer and wouldn?t hesitate to recommend to others.
