How old does a water heater have to be before replacing instead of repairing?

Most tank water heaters last around 8-12 years. If yours is in that range and failing, a plumber will usually recommend replacement over a repair that only buys a short time.

Can a Conway plumber install a tankless unit instead of a standard tank?

Many of the water heater providers here handle tankless conversions, though it depends on your gas line or electrical capacity, which the plumber will assess on site.

Is it worth repairing a water heater under warranty?

If the tank itself is still under manufacturer warranty, repair or a warranty-covered part replacement is usually the cheaper route versus paying full price for a new unit.

Water heater: repair or full replacement?

When a water heater starts acting up, the category page shows you who installs and repairs them, but it doesn't help you decide which one you need. This page walks through the practical signs that separate a repair job (thermostat, heating element, pressure valve) from a unit that's actually due for full replacement (tank age, rust in the water, tank leaking from the bottom).

Age and warranty status of the tank
Whether the leak is coming from a fitting (repairable) or the tank itself (not repairable)
Gas versus electric swap considerations if you're replacing anyway
Tankless conversion as an option some Conway plumbers offer during a replacement call

Providers featured here come from the Water Heater Installation & Repair category and handle both sides of this decision.

What it costs

Repairs are usually a part-and-labor job, driven by whether the part is a stock item or something the plumber has to source. Full replacement cost depends heavily on tank size, gas versus electric, and whether venting or code-required upgrades (like a new expansion tank or drip pan) are needed during the swap.
