The Hot Water Association (HWA) is a member organisation committed to effectively promoting the concept and use of stored hot water in domestic and commercial buildings in the United Kingdom and Republic of Ireland. HWA's membership accounts for nearly 100% of domestic hot water storage devices sold in the UK. The HWA exists to support, drive and promote the sustained growth and improvement of standards within the entire domestic hot water industry. The domestic hot water tank often escapes our attention, but it has a big role to play in the energy efficiency of our homes.

Tucked away in a cupboard, perhaps behind a pile of towels and bed linen, out of sight and out of mind. The domestic hot water tank often escapes our attention, but it has a big role to play in the energy efficiency of our homes. The demand for energy efficiency and alternative heat solutions such as solar, heat pumps and wood burning stoves is prevalent. Water heating is increasingly becoming a key consideration of any heating system, whether renewable or conventional. In the past few decades we have become the Impatient Nation.
