Protecting Your Water Heater Before, During, and After a Storm
Florida’s hurricane season puts extra strain on home systems, and your water heater is often overlooked until it fails at the worst possible time. Whether you have a traditional tank or a tankless unit, a few simple precautions can prevent costly damage and help your household get hot water back faster once the storm passes.
Before the Storm
- Turn off the gas supply or unplug an electric unit before evacuating or if flooding is expected in your area.
- If your water heater sits in a garage or ground-floor closet, elevate it on blocks if you have advance warning and time to do so safely.
- Check that the temperature and pressure relief valve and drain line are clear and functioning, since power surges during storms can cause pressure spikes.
- Fill extra containers with water in case service is interrupted, especially if you rely on well water with an electric pump.
During a Power Outage
Gas water heaters with standing pilot lights will typically continue heating water even without electricity, giving Florida homeowners an advantage during extended outages. Electric water heaters, tankless electric units, and gas models with electronic ignition will not operate until power is restored.
After the Storm
Inspect your water heater for water intrusion, rust, or damage to electrical connections before turning it back on. If the unit was submerged or exposed to floodwater, have a licensed plumber inspect it before restoring power or gas, since contaminated water and electrical components are a serious safety hazard.
Your HVAC system needs the same hurricane attention as your water heater. A damaged or improperly anchored AC unit can become a projectile in high winds. One Hour Heating & Air Conditioning® of Treasure Coast — our sister company serving the same communities — can inspect and properly secure your outdoor AC unit before hurricane season.
