Replacing old commercial instant hot water system

$200

Glenfield NSW 2167, Australia

25th Apr 2026

我家里有一台用了约17年的旧燃气热水器,已无法正常工作,需要更换。 这台旧机器比较特殊,是一台商业/工业级的即热式(瞬时)燃气热水器。 标签显示其燃气入口压力为 50 mbar (Pinlet max 50 mbar),由 SIT 在墨西哥组装。 目前在设备上能找到的标签照片已附上。 “预算 $200 是上门检测费和出方案的费用。换热水器的全包价请在报价时另外报。” 需要您完成的四项工作: 上门检测:请持牌燃气工携带专业设备,实测我家现有的燃气管道压力 (kPa/mbar) 和燃气类型 (Natural Gas 或 LPG)。 评估管径:我家的燃气管道较细 (目测约10mm),请评估是否需要更换管道以满足新家用热水器的供气需求。 提供解决方案:根据检测结果,请告知: 目前的燃气压力能否直接安装普通家用燃气热水器? 如果需要降压,安装一个调压器的费用是多少? 应该选哪种合适的家用热水器 (比如Dux 135L储水式或Rheem即热式),以及对应的全包报价。 提供总包报价:包含拆旧 + 运走旧机 + 提供并安装新机 + 必要的燃气调压器/管道改造 + 调试的固定包干价。 请带着您的 NSW Gasfitting Licence 来报价。任务发布地点在 Glenfield 2167,我可以拍照提供更多旧机细节。

Tehsein was professional and an excellent communicator during the heater inspection. He has great attention to detail and went beyond his scope of work by pointing out that our gas meter had a leak. Much appreciated!
