Homeowner checklist

Water heaters: heat pump, tankless or conventional?

Use these steps to plan, check and keep a record of your next actions.

• Record household peak hot-water demand and the existing equipment details.
• Ask how the proposed model serves the busiest hour and recovers afterward.
• Check its room-air, temperature, ducting and service-access requirements.
• Confirm how condensate, sound, power and existing venting will be handled.
• Review savings assumptions and the effect on the surrounding room.
