PLANNING / SELECTION / HANDOVER
Before choosing the equipment
List simultaneous showers, baths and other major draws. Ask how the proposed unit manages competing space-heating and hot-water demand, and compare a separate storage arrangement.
What belongs in the quote
Request the expected hot-water performance at local incoming water conditions. Include venting, water quality considerations and servicing access in the installation scope.
Think about the surrounding system
Start with the building heat loss, available energy supply and the way warmth reaches each room. Ask whether existing ducts, piping and emitters can support the proposed equipment. A replacement is an opportunity to investigate cold rooms and noisy operation rather than simply copying the old nameplate.
Three questions for your contractor
- What happens when two showers run?
- How is hot-water demand prioritised?
- Would separate storage better fit the household?
Prepare a useful first conversation
Bring the site location, building use, equipment model details and photographs of accessible equipment. Describe the problem or planned change and any access or shutdown constraints. Ask the contractor to identify design assumptions, excluded work, required approvals and who will commission the finished system.
This is a project-planning guide. Final equipment selection and installation details need a qualified contractor or designer familiar with the site.
