Preparing to replace a water heater

Choose a replacement water heater’s size and model around hot-water demand, available space, and installation requirements. The old tank’s capacity is useful information, but changes in household size or usage may call for a different solution.

Gather details of the existing equipment

If safely accessible, photograph the rating plate, heater, and surrounding space. Explain whether hot water meets everyday needs and any faults you have noticed. Mention upcoming changes such as another bathroom or a new heating system.

Ask plumbing and electrical professionals to assess the new unit’s suitability. Confirm the purchase only after connections and placement have been checked.

Check access and service space

Measure doorways along the access route and photograph any stairs. Establish how the old unit will be removed and the new one brought in. A space may fit the equipment’s outer dimensions but still lack room for installation or future servicing.

Ask how water will be managed at the installation location and how a possible leak would be noticed. These belong in the planning, rather than being left until delivery day.

Order a complete, working installation

Ask the quote to include the heater, disconnection and removal of the old unit, necessary plumbing and electrical work, materials, and commissioning. Name a contact who coordinates the different trades.

Agree on the expected water outage and instruction in using the new equipment. Ask about user checks, maintenance, and what to do if something goes wrong. A building-systems handover checklist helps ensure documents and instructions arrive with the installation.
