Define the application
Explain whether the question concerns a home, workplace or another setting, and where hot water is intended to be used. State what has already been specified and which points remain open.
Bring the information that exists
If a professional has prepared an equipment specification, identify the relevant model or requirements in the first message. Do not send confidential drawings or property access information through a general form; establish an appropriate channel for detailed documents later.
Confirm responsibilities before work begins
Product supply does not automatically include design, installation or commissioning. Establish the responsible professional, exact equipment and any separately agreed work in the actual project arrangement.
