Hot Water Association (HWA)

The Hot Water Association (HWA) was formed through the union of the two UK industry trade bodies, WMA (Waterheater Manufacturers Association) and MODUS (Manufacturers Of Domestic Unvented Systems).

The objectives of the HWA are "To be recognised as the leading body in domestic hot water storage and, through cooperation and partnerships, to support, drive and promote the sustained growth and improvement of standards within the entire domestic hot water industry".

Its role is to provide:
  • Information: From an explanation on how storage hot water systems work to the latest industry developments
  • Advice: From technical queries to advice on the Building Regulations/Byelaws.
  • Expertise: With the combined knowledge of member companies, HWA offers unrivalled expertise within the sector and continues to convene on technical bodies, standards committees and lobby for further development of legislation.
