2023 Drinking Water & Heat Forum – new title plus even more content 

3-minute read

The popular Drinking Water Hygiene Forum has now been given a new name and offers even more valuable input than before. This event programme will now operate under the title ‘Drinking Water & Heat Forum’. And it’s all in the name: buildings – new and old – must be supplied with drinking water and heat in a resource-efficient, climate-neutral way. The (technical) issues that arise from this fact can only be solved by an interdisciplinary approach. The new direction taken by the Forum aims to generate ideas, promote new approaches and create an opportunity for dialogue. Practical solutions and best practice, accompanied by key aspects from the latest technical codes, will be presented on six separate dates in February and March 2023. Places for these events are limited – please register here to avoid disappointment
