What is BS 7593:2019+A1:2024 - Code of practice for the preparation, commissioning and maintenance of domestic central heating and cooling water systems about?
An amended national standard, BS 7593:2019+A1:2024 is an industry code of practice on how to prepare circulating water during the initial commissioning (or re-commissioning) of domestic central heating and water-cooling systems.
Who is BS 7593:2019+A1:2024 Code of practice for the preparation, commissioning and maintenance of domestic central heating and cooling water systems for?
Users of this standard include:
- the heating and cooling system industry;
- manufacturers;
- suppliers of water treatment products, mechanical devices and other fittings
- consultants;
- water treatment specialists; and
- testing laboratories.
What does BS 7593:2019+A1:2024 - Code of practice for the preparation, commissioning and maintenance of domestic central heating and cooling water systems cover?
BS 7593:2019+A1:2024 supplies recommendations on best practices for the preparation of the circulating water in open vented or sealed heating and cooling systems in individual domestic premises during initial commissioning (or re-commissioning following major remedial work, e.g. boiler replacement).
It also recommends ongoing water treatment to ensure appliance and system protection and continued efficiency in operation.
BS 7593:2019+A1:2024 also ensures awareness of potential problems and of remedies that maintain efficiency and maximize the life of heating and cooling systems. It covers sealed cooling systems; treatment of water to overcome scale and corrosion; cleaning and flushing of systems; and the use of in-line filters.
Why should you use BS 7593:2019+A1:2024 Code of practice for the preparation, commissioning and maintenance of domestic central heating and cooling water systems?
The UK government recognizes that heating homes is a major contributor to CO2 emissions in the UK, thus it's more important than ever to make sure that domestic central heating and cooling systems operate at peak efficiency.
With that in mind, BS 7593:2019+A1:2024 helps:
- minimize corrosion and scaling;
- damage and premature failure;
- protect against freezing;
- maintain clean water in systems;
- protect against microbial growth;
- minimises any remedial action needed;
- prolongs the life of the system and its components;
- extend system life;
- lower energy consumption when compared to a dirty/ scaled system
- maintain system performance;
- minimize noise by reducing kettling caused by limescale; and
- enable compliance with Part L of Building Regulations.
What has changed?
This amendment links BS 7593:2019 with the newly developed BS 9593:2024 Assessment for the performance of chemical inhibitors for use in domestic central heating and cooling water systems – Test method.
