Central Heating & Hot Water (CENWAT) Training & Assessment Course (ACS Certification)

Course Overview

The Central Heating & Hot Water (CENWAT) Training & Assessment Course is the industry-standard ACS qualification for gas engineers working on boilers and hot water systems. CENWAT replaced the previous CEN1 and WAT1 modules and became effective from April 2011. It is required for engineers working on a wide range of domestic central heating and hot water appliances across both residential and commercial settings. This CENWAT gas training course is not fuel-specific, meaning it applies to appliances powered by both Natural Gas (NG) and Liquefied Petroleum Gas (LPG).

  • Safely install, commission, and service gas boilers and hot water systems
  • Identify key gas safety components and system controls
  • Diagnose and correct installation faults in accordance with manufacturer instructions
  • Carry out performance and operational checks on water heating appliances
  • Measure temperature rise and flow rates on hot water systems

Apply current gas safety legislation and industry best practices

Course Method

The CENWATACS assessment includes:

  • Practical installation and commissioning of a gas boiler
  • Fault identification and servicing exercises
  • Operational testing of instantaneous water heaters
