Replace 135L Gas Storage Hot Water System - Baulkham Hills
$1,500
Baulkham Hills, New South Wales
3rd Mar 2026
Hi, I need a licensed plumber/gas fitter to replace an existing gas storage hot water system at my townhouse in Baulkham Hills. Key Requirements & Constraints: Unit Type: 135L Gas Storage Tank (Replacement). Brand: Any reputable brand is fine (e.g., Rheem, Vulcan, Dux). Location: Outdoor installation. Gas Pipe Constraint (Critical): The existing gas supply line is 15mm and cannot be upgraded. Please ensure the unit you recommend/install is compatible with a 15mm gas line (must not require a 20mm connection). Disposal: NOT required. I want to keep the old unit on-site, so you do not need to take it away. Your Quote Should Include: Supply and installation of a new 135L unit (or let me know if you want me to supply it). All necessary valves and fittings. Testing and commissioning. Requirements: Must be a licensed gas fitter. Must provide a Certificate of Compliance after installation. Existing unit is a 199 MJ/h continuous flow, but I am switching to a 135L storage tank to better suit the 15mm gas line
