For many Filipino households, especially those living in colder regions like Baguio or Tagaytay, or in condo units around Metro Manila, water heaters are no longer a luxury but a necessity. Whether you're using a tank-type heater or a modern tankless model, proper maintenance helps you avoid cold showers, extend your unit’s lifespan, and save on electricity.

Here’s your essential guide to keeping your water heater in tip-top condition, even without calling a plumber right away.

1. Check for Signs of Trouble

Start by paying attention to how your water heater is behaving. These are early signs that maintenance is needed:

Don’t wait until these issues become major problems. Small maintenance steps go a long way.

Water takes longer to heat
Strange noises like popping or rumbling
Rusty or discolored water
Water leaking from the tank or connectors
A sudden spike in your electric bill

2. Flush Your Water Heater Regularly

In the Philippines, hard water buildup (caused by minerals in our supply) is a common issue. This leads to sediment collecting inside the tank and reduces heating efficiency.

How to flush a water heater:

Turn off the power supply (or switch off the breaker).

Close the cold-water inlet.

Attach a hose to the drain valve and let the water flow into a bucket or outside.

Let it drain completely and flush out sediment.

Close the drain valve, open the cold inlet, and turn the heater back on.

Do this once or twice a year to keep things running smoothly.

3. Inspect the Anode Rod

The anode rod helps prevent rusting inside the tank. Over time, it corrodes, doing its job, but it needs replacing every few years.

If you’re not confident doing this yourself, call a licensed tubero to safely inspect and replace it.

Signs that the anode rod needs replacing:
Rotten egg smell from hot water
Visible corrosion or thinning on the rod (if you check it)
Water heater over 3–5 years old with no prior maintenance

4. Adjust the Thermostat to 50–60°C

Many heaters are factory-set too high. Keeping the temperature between 50–60°C (122–140°F):

This is especially important if you have kids or seniors in your household.

Prevents scalding
Saves energy
Extends heater lifespan

5. Turn It Off When Not in Use

If you're leaving for a weekend trip or vacation, turn off the water heater to avoid unnecessary energy use. For electric tank heaters, this can be done easily from your circuit breaker panel.
