Estimate the total cost
Compare written quotes that include equipment, labor, and any necessary changes to the site. Look at the energy label, fuel price, and how much hot water your household actually uses. A lower purchase price can come with a different operating cost.
Size for your real use
List the fixtures you use during your busiest hour. Match equipment capacity to those habits, and account for changes such as an added bathroom. Proper sizing helps you avoid paying for capacity you rarely use or running short during a normal day.
Keep the paperwork
Save installation, maintenance, and warranty records. They make it easier to service the equipment and give a future buyer concrete information about the system.
