Longer Showers, More Efficient Hot Water

Your comprehensive guide to water heater maintenance.

Hot water is deeply woven into every part of your day, from your morning shower to your evening dishes. It also accounts for roughly 18% of the average U.S. home’s energy consumption, making your water heater one of the most consequential appliances you own. Keeping it running at peak efficiency isn’t just about comfort — it’s about managing energy costs and protecting a significant investment.

For homeowners in Holyoke and throughout Western Mass, a combination of smart DIY upkeep and professional maintenance is the best way to get there. FSi Oil Services (along with our sister company FSi Propane) is here to help with both.

In this article, we’ll discuss some steps you can take to get the best performance from your hot water system.

1. Set Your Water Heater Thermostat Wisely

Small thermostat adjustments can meaningfully reduce energy consumption and wear on your equipment without any noticeable drop in comfort. Two easy changes to consider:

• Lower the temperature to 120°F. Many water heaters ship with a default setting of 140°F, but 120°F is more than adequate for household needs. It reduces energy use, lowers the risk of scalding and still eliminates harmful bacteria.
• Use vacation mode when you travel. Before leaving home for an extended period, switch your water heater to vacation mode or its lowest setting to avoid heating water you won’t be using.

2. Flush Your Tank Every Year

Sediment naturally builds up inside your water heater tank over time, contributing to corrosion and reduced efficiency. An annual flush clears it out. Here’s how:

1. Switch the water heater off.
2. Close the cold water supply valve.
3. Connect a hose to the drain valve and direct it to a utility sink, floor drain or outdoor area.
4. Open a hot water faucet somewhere in your home to prevent a vacuum from forming.
5. Open the drain valve to empty the tank.
6. Once drained, reopen the cold water supply to flush out remaining sediment.
7. Close the drain valve, remove the hose and let the tank refill fully.
8. Restore your water heater to its normal operating setting.

3. Schedule Annual Professional Maintenance

Just as your heating system benefits from a yearly tune-up, so does your water heater. The skilled plumbers at FSi Propane can inspect, calibrate and service the critical components of your hot water system, catching small issues before they become costly problems. Regular professional maintenance translates to better performance, lower energy bills and a longer-lasting unit — which means more hot water for longer, more comfortable showers.

4. Recognize the Warning Signs of a Failing Unit

A traditional storage tank water heater typically lasts between 8 and 12 years. If yours is approaching or past that range, it’s worth exploring your replacement options now rather than waiting for an unexpected breakdown — which can cause property damage and leave your household without hot water for days. In the meantime, watch for these warning signs:

• Rumbling, banging or other unusual sounds
• Rusty or discolored water from hot taps
• Pooling water or moisture around the base of the tank
• Unexplained increases in energy costs
