Quick answer
The right replacement water heater depends on your home: household size and peak demand, fuel type, available space, and budget. Tank, tankless, and heat-pump each fit different homes. Size to your real hot-water demand, pick the type that matches your space and goals, and pair it with softening for hard Central Texas water.
Why size a water heater to the home, not a default?
An undersized heater runs out of hot water; an oversized one wastes energy and money. The right size is set by your peak demand — how many fixtures run at once and your household's habits — measured as tank capacity (gallons) plus recovery, or, for tankless, flow rate (gallons per minute) at your incoming water temperature. This is a home-specific calculation, which is exactly what a generic "50-gallon, done" recommendation skips.
Tank, tankless, or heat-pump — which fits your home?
- Standard tank (Rheem, Bradford White): simplest swap, lowest up-front, needs space for the tank.
- Tankless (Navien): endless hot water, space savings, higher up-front + venting; needs annual descaling here.
- Heat-pump/hybrid: most efficient, lowest operating cost, rebate-eligible; needs air space and clearance.
Your space, fuel, demand, and how long you'll stay decide the winner — see the best brand for a Central Texas home.
What gets the replacement wrong?
Wrong size (cold showers or wasted energy), ignoring the water (a new unit on untreated hard water scales and fails early), and skipping code — no expansion tank, poor venting, no permit. Replacing the heater without addressing the hard water that killed the last one just restarts the clock — which is why we so often pair a new unit with softening.

Key takeaways
- Size to your peak hot-water demand — undersized means cold showers, oversized wastes money.
- Tank = simplest/cheapest; tankless = endless + descaling; heat-pump = efficient + rebate-eligible.
- Space, fuel, demand, and how long you'll stay decide the type.
- Pair any new unit with softening so hard water doesn't shorten its life.
Frequently asked questions
- What size water heater do I need for my home?
- It's based on your peak hot-water demand — household size and how many fixtures run at once — expressed as tank gallons + recovery, or tankless gallons-per-minute. We calculate it for your home rather than defaulting to a generic 40 or 50 gallons.
- Should I switch to tankless or a heat-pump when I replace?
- Maybe — tankless suits high-demand homes wanting endless hot water; heat-pump suits efficiency-minded homes with space and rebate interest. A standard tank is the simplest, cheapest swap. We'll show you the trade-offs and the rebate math for your situation.
