The Heating and Hotwater Industry Council (HHIC) and Heat Pump Association (HPA) have published updated guidance to help heating and plumbing professionals maintain safe, efficient and long-lasting heating and hot water systems in UK homes.
The document, ‘Maintaining a Healthy & Efficient Domestic Heating & Hot Water System’, was developed in collaboration to ensure the guidance reflects best practice across both boiler and low-carbon heating systems.
The guidance outlines best practice procedures for cleaning, flushing, protecting and maintaining domestic heating systems.
HHIC director, Stewart Clements, said: “Heating engineers play a vital role in keeping homes safe, warm and energy efficient. This updated guidance supports them with clear, practical steps for maintaining system health, helping to ensure that every installation delivers optimal performance and aligns with current regulations and standards. Our collaboration with the HPA has ensured that this advice applies equally to both boiler and heat pump systems as the market evolves.”
The paper ‘Maintaining a Healthy & Efficient Domestic Heating & Hot Water System’ can be found on the Heating and Hotwater Industry Council (HHIC) website.
