"This is my third Ecooil tank installation Will fit within a footprint of 900 x 1800 and is good looking . The top exit tank comes complete with fire valve and Tigerloop. (must use a de-aerator on top feed tanks). Price is good and the service excellent with delivery texted/phoned ahead. Can have pipe exit at front or rear (reverse tank!) . reasonably manouverable on trolley by one person. 2 inch fill pipe is only access to inner tank. Apollo Ultrasonic gauge ready to go. Mechanical dial gauge inside lid."
