Tips for Maximizing Water Heater Efficiency in the Summer

August 5, 2025

In the summertime, the weather is warmer, you’re outside longer, and you may notice that you are using a lot more water than usual. During this time, it’s essential to consider the pressure your water heater is under, as it tries to meet the summer season’s demand. We’ve put together a few tips to help you maximize your water heater efficiency and get through this time of year more efficiently.

Adjust the temperature

Ready to maximize the efficiency of your water heater this summer? Start by lowering the temperature of your water heater! Summer weather is often humid, hot, and sticky, so you’re likely not showering with extremely hot water anyway. We recommend setting the water temperature to around 120°F to prevent your water heater from heating water to a temperature higher than necessary. This will also help your water heater work less, reducing the amount of wear and tear on the unit.

Check for leaks

Inspect your water heater for any leaks or damage. A small leak may not seem like a big deal, but if it has been dripping for a while, it could be wasting a lot of water. Check for damp spots around the base of the water heater, water stains on the floors and walls, and any signs of rust or corrosion on or around the tank. As soon as you notice any signs of a leak or damage to the water tank, contact the professionals at Eastern Plumbing promptly. If left unaddressed, a leak may even cause bigger problems and expensive repairs down the road.

Flush the tank

To protect your water heater and keep it running efficiently and smoothly for an extended period, you should regularly flush the tank. Over time, sediment and minerals accumulate in the tank, potentially affecting the water flow and damaging parts, which can shorten the lifespan of your water heater. Flushing the tank removes these deposits and ensures your water heater operates at peak performance.

Insulate the tank and pipes

Even when the temperatures reach the 90s, insulating your pipes and water tank heater can help improve efficiency. Having your pipes and tank insulated means that you experience less heat loss, maintain a suitable water temperature for much longer, and keep your water heater from working too hard. Reduce energy waste and inefficiency in your home with insulated pipes, potentially saving you money in energy costs each year.

Have regular maintenance performed

Regular maintenance is a key part of an efficient water heater. Having a professional plumber routinely inspect your water heater will not only keep it operating at full efficiency but also promote a longer lifespan and catch any problems before they become significant risks. Summer is the perfect time to schedule a yearly tune-up, and the best way to maximize efficiency is to be proactive.

Upgrade your water heater.

When you are spending more and more money on repairs and maintenance, it may be more cost-effective to replace your water heater. Consider replacing your water heater to save on overall costs and maximize efficiency. Typically, water heaters last around 10-15 years, and those that are older than that will require significantly more energy to operate. A new model requires an upfront investment in labor and installation, but it can save you money over time on your energy bills.
