How a Tank Water Heater Works
- Cold inlet — the dip tube carries it to the tank bottom
- Burner — heats water at the bottom of the tank
- Anode rod — sacrificial rod that fights corrosion
- T&P valve — releases pressure if it builds too high
- Hot outlet — draws the hottest water from the top

What Size Water Heater Does Your Home Need?
Sizing is where most water heater regrets start. Too small and the third shower of the morning runs cold; too large and you pay to keep water hot that you never use. The right size depends on your peak-hour demand — how much hot water your household uses in its busiest single hour. As a rough guide, a 40-gallon tank suits one to two people, 50 gallons fits a family of three or four, and larger households or homes with soaking tubs often need 60 to 80 gallons. Fuel type matters too: propane units recover faster than natural gas, so tank size needs vary by fuel type as well as household size. We size your replacement from how your household actually lives, not from whatever happens to be on the truck. Our plumbers are not paid on commission, so the recommendation you get is the size you need — nothing bigger.

Yes. Windham is part of our Cumberland County service area, and J&R Mechanical Services handles tank water heaters for homes throughout the area. Call (207) 902-8899 or book online to schedule.
Will you pressure me toward a more expensive tankless unit?
No. We recommend tankless only when it genuinely fits your home and usage. For many households, a well-installed tank heater is the right value — and we will say so plainly.
How long does a tank water heater last?
Typically ten to twelve years. Regular maintenance — flushing sediment and replacing the anode rod — can extend that, while hard water and neglect shorten it. If your heater is past ten years old, it is smart to plan the replacement before it fails.
