Eight months of hot water demand a heater built for it
Hartford homes call for heat from October through May, and the water heater is working through most of that stretch too. Winter nights averaging 21°F mean the water coming into the tank starts out cold, so the burner or elements have more work to do to bring it up to temperature.
The federal minimum efficiency for storage water heaters is not one number. It is a formula tied to the tank's rated volume, checked against four different draw patterns, so two tanks of different sizes can face different minimums even from the same line. A licensed installer sizes the new unit to your household's draw and confirms it clears the standard for that size.

- How do I know it's time to replace my water heater?
- Watch for water around the base of the tank, water that takes longer to heat, or water that comes out rusty. A tank that's leaking from the body itself, not a fitting, is done, since that means it's rusted through from the inside. Age matters too. Most tank water heaters last a decade or a little more, and once one starts needing repairs it tends to need them again soon after. If yours is in that age range and giving you trouble, replacing it is usually the better call than paying for another repair.
- Should I switch to a tankless water heater?
- It depends on what you want out of it, not on whether your current tank is failing. A tankless unit heats water as it flows through rather than storing it, so you don't run out during a long shower or back to back loads of laundry. It also takes up much less space than a tank. What it won't do is deliver hot water instantly at the faucet. The water in the pipe between the unit and the tap still has to travel, so there's a wait either way. A contractor can look at your gas line and venting to tell you what switching would actually involve in your house.
- What changes when you install a tankless water heater?
- The biggest change is what feeds it. Tankless units draw much more gas at once than a tank does, so the gas line often needs to be upsized to keep up. Venting changes too, since tankless heaters vent differently than a standard tank and the existing vent usually can't just be reused. There's no tank standing by with a reserve of hot water, so output depends on the unit keeping up with demand in real time rather than draining a supply. A contractor can check your home's gas line and venting to see what the switch would take.
