Tank vs tankless: the honest math

A comparable gas tank installs for less upfront than a tankless. So the real question is: what does the extra cost buy?

Twice the lifespan. Tanks in Central Kentucky last 8–12 years (our hard water pushes them toward 8–10). A descaled tankless runs 18–20. Over twenty years you'll likely buy two tanks — or one tankless. That alone closes most of the price gap.

Hot water that doesn't run out. A tankless heats water as it flows, so the fourth shower is as hot as the first. If your household schedules showers around the water heater, this is the feature you're actually buying.

20–30% lower gas use. A tank reheats 50 gallons all day whether you use it or not. Tankless burns gas only when a tap opens. Real savings, but modest month to month — not a fortune. Anyone promising the unit "pays for itself in two years" is selling, not math-ing.

The honest catches: the annual descale is part of the true cost of ownership here — Kentucky water runs 150–200 mg/L hardness and scale is what kills heat exchangers. Some homes need a gas line upsize or new venting, which adds real dollars we'll show you at the quote visit. And when it's 10°F outside, groundwater comes in colder, so effective flow drops — which is why we size for January.

Our plain recommendation: staying 7+ years, 2+ bathrooms, tired of cold showers — tankless is worth it. Selling in three years or a one-bathroom house — put a good tank in and keep the difference.

Which size do you need?

Size by simultaneous demand, not house size

  • 6.4 GPM: one shower + a sink at the same time. Right for 1–2 bath homes and couples.
  • 8.4 GPM: two showers at once, or shower + dishwasher + laundry. The sweet spot for most Richmond and Lexington family homes.
  • 11.0 GPM: three-plus bathrooms, soaking tubs, teenagers. Nobody waits, ever.

A shower draws roughly 2 GPM, a kitchen sink 1.5, a washer 2. Add up what actually runs at the same time in your house on a Saturday morning — that's your number. We'll confirm it during the quote visit.

Tankless FAQ

It depends on the size and your home's setup — 6.4 GPM, 8.4 GPM, and 11.0 GPM Rheem indoor natural gas units (5-year warranties, installed) each price differently. Call 859-408-3382 for a free quote. $100 off with HEATER100, and 0% financing available on larger jobs.
18–20 years with an annual descale — roughly double a tank. Skip the descaling in our hard water and you can cut that in half and jeopardize the manufacturer warranty. The yearly descale service is part of the honest total cost — call for a free quote.
Maybe — a tankless burner draws far more gas than a tank's, and some older homes run 1/2" lines that can't feed it. We check the line, the meter, and the venting path during the free quote visit and price any upgrade as its own line item before you decide.
Yes, when sized correctly. Kentucky groundwater drops into the 40s in winter, which reduces a unit's effective flow rate. That's exactly why we size for January demand — a unit that's perfect in July and undersized in February was mis-sold.
A straightforward swap from an existing tankless runs about half a day. A tank-to-tankless conversion (new venting, gas work, mounting) is typically a full day. Flat-rate either way — quoted before we start.
