6 Common Water Heater Myths Augusta Residents Should Ignore

September 22, 2026

When it comes to water heaters, Augusta homeowners are given plenty of advice—some helpful, much of it not. At Garand Plumbing, we’ve lost count of how many calls we get after a DIY fix or install goes sideways, all because of a myth or half-truth found online or passed from neighbor to neighbor. Knowing what really works for Maine homes saves money, energy, and frustration.

Believing the wrong thing about your water heater can leave you out in the cold when you need hot water most. Whether you’re thinking of upgrading, troubleshooting issues, or getting regular maintenance, separating fiction from fact is key—and Garand Plumbing is here to set the record straight. Let’s clear up the biggest misconceptions we encounter, based on real-world service calls in Augusta and throughout Maine.

Tip #1: Tankless Water Heaters Don’t Work in Cold Climates

This is common in Maine—people assume tankless systems are useless in cold weather. The truth is, today’s tankless water heaters can be properly sized and installed to perform well even in Augusta winters.

• Sizing and installation matter most: Get a technician to assess your needs.

• Choose cold-climate-rated units: Some tankless heaters handle lower inlet temps better.

• Insulate supply lines: Prevent freeze-ups and maximize efficiency.

→ From a professional standpoint: The biggest failures happen when homeowners install the wrong unit or skip the pipe insulation.

Tip #2: Bigger Tanks Mean Endless Hot Water

Having a larger tank isn’t a guarantee against cold showers—recovery rate and use patterns matter.

• Check the recovery rate: The speed of reheating after usage is key for families.

• Consider usage times: Kitchens, laundries, and showers used at once can drain any tank.

• Tankless or hybrid units: Sometimes a demand-based system is a better fit in Maine homes.

→ A quick tip to remember: Bigger isn’t always better—it’s about matching size and typical demand.

Tip #3: Tank Heaters Don’t Need Maintenance

Many people think “set and forget” works, but neglecting your water heater means more breakdowns and worse efficiency.

• Flush annually: Remove sediment that builds up faster in Maine’s hard water.

• Inspect anode rods: These sacrificial rods keep your tank rust-free much longer.

• Test the safety valve: Regular checks prevent pressure or temperature-related failures.

→ From a professional standpoint: Ignoring maintenance is easily the top cause of premature heater replacement in Augusta homes.

Tip #4: You Always Have to Replace a Leaking Water Heater

Not every leak means your water heater is finished.

• Check the connections: Sometimes the “leak” is a loose fitting or a gasket.

• Inspect the tank: Only serious tank corrosion means total replacement.

• Get a plumber’s diagnosis: Minor fixes can buy years of extra service.

→ A quick tip to remember: Call for service at the first sign—small leaks caught early often avoid tank replacement.

Tip #5: Setting a High Temperature Prevents Bacteria

It’s true that water temperature plays a role in controlling bacteria, but turning the thermostat up high brings more risk than reward, especially in Maine homes with young children or older residents. Overheating can cause scalding burns long before it would kill off bacteria like Legionella.

• Safe range is 120°F: Hot enough to limit bacteria, safe for most households.

• Insulate your tank and lines: This maintains safe temperatures without the hazard.

• Flush the system periodically: Flushing is much more effective against bacteria than overheating.

→ From a professional standpoint: Bacteria prevention starts with regular maintenance, not just turning up the dial.

Tip #6: Water Heater Efficiency Is Only About the Model

Many assume that simply buying a new, high-efficiency water heater is the answer. The reality is, installation details and usage patterns have just as much impact on performance in Augusta homes.

• Proper venting: Especially critical for gas heaters—improper venting can reduce both efficiency and safety.

• Installation position: Shorter pipe runs lose less heat in cold Maine basements.

• Sizing to needs: Oversized units cycle inefficiently and cost more to run.

→ A quick tip to remember: The best unit, poorly installed, won’t save you money or frustration in the long run.

Frequently Asked Questions

Do tankless water heaters really work in Maine homes?

Absolutely, as long as they're selected and installed with local conditions in mind. Augusta’s cold winters require units with strong flow rates and freeze protection, and pipe insulation is a must. Garand Plumbing regularly installs tankless systems across Maine with excellent results.

How long should a water heater last in Augusta?

Most standard tank heaters in Maine last about 8–12 years, while a well-maintained tankless system can often exceed 15 years. Hard water and lack of yearly service are top factors that lower a heater's lifespan. Garand Plumbing recommends annual flushes and checkups to maximize investment in any unit.

Do bigger tanks guarantee more hot water for large families?

Not necessarily. Bigger tanks mean more storage, but without a fast enough recovery rate or matching your household’s peak usage periods, you might still run out. Considering water usage patterns and, if needed, exploring hybrid options often gets better results for Augusta families.
