When the cold arrives and the wind begins to bite, an outdoor water heater can become a ticking time bomb. Cold weather can freeze the water inside the tank, burst pipes, and even cause the heater to fail entirely. Fortunately, there are a number of simple, effective steps you can take to protect your outdoor water heater and keep it running smoothly all winter long.

Check the Heater Before the Chill Arrives
• Look for visible cracks, rust, or loose fittings.
• Ensure the pressure relief valve works; a faulty valve can cause dangerous pressure buildup.
• Confirm the temperature and pressure relief valve is appropriately sized for your unit.

Add a Protective Cover or Enclosure
• Employ a weather‑proof, insulated cover built for outdoor water heaters.
• If the unit sits in the open, consider constructing a basic shed or enclosure that ventilates properly.
• Ensure the cover doesn’t retain heat; proper airflow averts overheating.

Wrap the Pipes and Tank in Insulation
• Wrap the tank in top‑quality insulation blankets, then secure with zip ties or straps.
• Cover all cold water supply and return lines, especially the portions outside the building.
• Use foam pipe insulation sleeves for smaller pipes and a thicker blanket on the tank.

Drain Water in Very Cold Weather
• In places with temperatures below -20°F, contemplate draining the tank completely to keep it from freezing.
• Keep the faucet open so trapped water can drain.
• Should you keep the tank full, mount a heat tape or small electric heater on its outside to prevent freezing.

Add a Heating Element or Heat Tape
• Heat tape can be wound around the tank and pipes, sourcing power from a close outlet to keep metal from freezing.
• For a more powerful option, fit a small electric heating element that triggers automatically when the temperature falls beneath a selected threshold.

Place the Heater Away from Drafts
• Place the heater in a spot protected from direct wind.
• Use windbreaks such as plants, fences, or a low wall to dampen the chill.

Check and Maintain the Pressure Relief Valve
• Every winter, lift the valve’s lever and allow a small amount of water to flow out.
• Ensure the flow remains steady and that the valve seals properly afterward.

Set a Low‑Temperature Thermostat
• Set the thermostat lower during the coldest months to limit the amount of water that could freeze.
• Usually the winter setting falls between 120°F and 125°F, maintaining water at a usable temperature while curbing energy use.

Provide a Backup Heating Source (Optional)
• If you need a lot of hot water, install a secondary backup heater, such as a small electric boiler, that can activate if the main unit fails.

Book a Professional Inspection
• Annually, have a licensed plumber inspect the heater, insulation, and electrical connections.
• An expert can find problems that are not obvious to homeowners and propose upgrades if necessary.

Mistakes to Avoid
• Omitting the insulation blanket: Even a minor gap permits cold air in.
• Employing inexpensive heat tape: Cheap versions may not retain enough heat and can wear out quicker.
• Too much insulation: Over‑insulation can trap heat and cause overheating.
• Ignoring the T&P valve: A blocked or stuck valve poses a safety risk.
