On a cold morning, nothing beats taking a warm shower. In the UAE, though, that comfort depends on one hard-working appliance: your water heater.
Most people don’t think about their water heater maintenance until something goes wrong, which is usually at the worst possible time. When the weather gets colder, the water that comes in is colder, demand goes up, and any maintenance problems that are still there become more obvious.
If you plan ahead, you won’t have to take cold showers, get surprise repair bills, or pay a lot for energy later. This blog shows you how to care water heater in winter. Why it’s important to get ready for winter
Even in a warm place like the UAE, the temperature of incoming water drops in the winter. Your heater has to work harder to keep the right temperature, which can cause: Higher energy consumption, Slower heating, and Unexpected breakdowns
Hard water in Dubai and the Gulf also causes limescale to build up in tanks and pipes, which makes your system work less well and wears it out faster.
Making sure your water heater maintenance is ready means:
- Hot water that stays the same all the time
- Lower energy bills
- Longer equipment life
- More safety for your family

Step 1: Check your water heater
Start by looking over everything carefully:
Check tanks and pipe joints for leaks, rust, or corrosion. Small leaks can make things less efficient. For solar systems, look at the collector panels, pipes, and insulation. Dust or debris can get in the way of sunlight and make heating work less well.
Depending on the type of system you have, check the wiring, electrical connections, pilot lights, or burners.
Tip: Call a professional for water heater maintenance if you see rust or leaks before they become a big problem.
Step 2: Get rid of the sediment
Hard water deposits and sediment build up at the bottom of tanks, which makes them less efficient.
Before winter, empty and clean your tank completely.
Check the circulation pipes for scaling to make sure the water flows smoothly in solar systems.
Tip: Do this twice a year, once before summer and once before winter, for best results.
Step 3: Look at the Anode Rod
The sacrificial anode rod protects the tank from corrosion. It wears down over time.
Inspect the rod every 1–2 years and replace it if it’s heavily corroded or less than half an inch thick. This simple water heater maintenance step can extend your heater’s lifespan by several years — especially in Dubai’s hard-water environment.
Step 4: Check the Temperature and Pressure Relief Valve (TPR)
The TPR valve is a key safety feature that releases excess pressure to prevent tank damage. To test it:
- Raise the lever a little and let the water flow.
- If nothing happens or it leaks after that, get a new one right away.
If you don’t take care of this valve, pressure can build up, especially in the winter when heaters work harder.
Step 5: Put insulation around tanks and pipes
Insulation is the key factor in maintaining water temperature and preventing heat loss.
- Use insulation blankets to cover tanks in garages, on roofs, or outside.
- Put insulation on the first few feet of both hot and cold water pipes.
- Make sure the insulation on the pipes that go from the collectors to the tanks is still good for solar systems.
Even in mild winters in the UAE, good insulation can cut down on standby heat loss by as much as 30%.
Step 6: Change the settings on the thermostat
A lot of people turn up the heat in the winter to warm up water faster. This wastes energy and makes it more likely that you will get burned.
Set the thermostats to between 49°C and 55°C (120°F and 130°F).
If your heater has an older manual thermostat, consider upgrading to a smart thermostat for better control, monitoring, and energy savings.
Step 7: Set up a time for a professional to come and fix things.
A trained technician can find problems that you might not see, such as small leaks, broken thermostats, or heating elements that are worn out.For solar systems, technicians can also check the performance of the collector, the circulation pumps, and the controller units to make sure your setup gives you hot water all season long.
Step 8: Make the most of energy efficiency
As the demand for hot water rises, so does energy use. But with simple habits, you can make your system more efficient
- Turn off your heater when traveling or away for long periods.
- Use low-flow showerheads to reduce water demand.
- Fix leaky faucets — even a slow drip wastes hundreds of liters monthly.
- Keep solar panels clean for maximum sunlight absorption.
These steps help you save energy and keep your system running well.
Step 9: Make plans for future upgrades
If your water heater is over 8–10 years old, it might be time to consider an upgrade. Modern systems, especially solar and hybrid heaters, are more energy-efficient, eco-friendly, and cost-effective.
Upgrading before winter enhances comfort, saves energy, and supports a sustainable lifestyle.
conclusion
In the winter, we need to take extra care of both our lives and our property. One important thing to pay attention to in Dubai is your water heater maintenance. It’s important to get a full check-up before winter so you don’t have any problems when it gets cold. Getting your water heater ready might seem like a small thing to do, but it will make sure you always have hot water, save you money on your energy bills, and make your equipment last longer.
