Why the Florida version of this decision is different
Most tankless advice online is written for cold-climate installations, where incoming water can arrive near freezing and the unit has to lift it fifty or sixty degrees. Here, groundwater and surface-sourced supply arrive warm most of the year. The unit has far less work to do per gallon, which means a smaller unit delivers the same simultaneous-fixture performance than the same house would need up north.
That is the good news. The offsetting local factor is water chemistry. The mineral load that scales tank heaters also scales a tankless heat exchanger, and a heat exchanger is a narrower, more sensitive path than the bottom of a forty gallon tank. Descaling is not optional maintenance on a tankless unit in this area — it is the condition on which the unit's life and its warranty both depend. Many owners here pair the install with softening or conditioning for exactly this reason.
What the installation actually involves
Gas units. The burner input is far higher than a tank's, so the existing gas line is frequently undersized and has to be upsized back to the meter. Venting is sealed, category-specific, and cannot reuse a tank's atmospheric flue. Combustion air has to be accounted for.
Electric whole-home units. No venting and no gas work, but the electrical demand is large — commonly multiple dedicated double-pole circuits. Homes on older service capacity often need panel work, which can exceed the cost of the heater.
Either way: isolation valves for flushing, a condensate path on a condensing unit, and a permit and inspection through whichever authority covers the address.
Who should not do this
If the only goal is a cheaper monthly bill, the payback maths is weak here. If the tank failed yesterday and you need hot water tonight, a tankless conversion is not the same-day job a tank replacement is. And if nobody in the household will ever descale it, a tank is the more honest choice — it tolerates neglect better.

Common questions
What size tankless water heater do I need for a 2,000 square foot house?
Size on simultaneous flow and temperature rise, not square footage. In this area groundwater arrives warm — often in the seventies — so the rise needed to reach a 120 degree setpoint is small compared with a northern install. That typically puts a household running two fixtures at once in the range of 6 to 8 gallons per minute. A contractor should measure your actual inlet temperature rather than assume it.
What are the downsides of a tankless water heater?
Three real ones. The install cost is roughly double a tank. Hard water scales the heat exchanger, so it needs descaling on a schedule or the warranty and the efficiency both suffer. And there is a short delay and a minimum flow rate before it fires, so a trickle from one tap may not trigger it at all.
Can I put a tankless unit where my tank is now?
Usually the location works, but the connections rarely transfer as-is. A gas unit typically needs a larger gas line and its own sealed venting. An electric whole-home unit needs substantial dedicated circuits and often a panel upgrade. The unit is the cheap part of the change.
Does a tankless water heater actually save money in Florida?
Some, mostly from eliminating standby loss on a tank sitting in a hot garage. The saving is real but modest, and on its own it does not pay back the installation difference quickly. People who are happy with the switch usually wanted endless hot water and the reclaimed space, with the efficiency as a bonus.
