Power surge from winter storm fried everything! They came so fast, and I was a new customer then. I was so impressed I bought the service contract they offer-as I knew there was going to be more required, and they do plumbing and heating, too. This time the replaced my entire electric (fuse) box. Day long project. I like that I get the same service technicians, and they have all been amazing. They follow up on everything, too. 👍🏻
They came out wishing an hour of my phone call and fix the issue right away

4 Clear Signs Your Home Could Benefit from a Tankless Water Heater

Traditional water heaters are reliable for a time, but there are clear signs that an upgrade is overdue.

Watching for these issues can save you money, improve comfort, and prevent future emergencies.

If your showers or laundry cycles leave you waiting for water to heat up, your current tank may not meet your household’s needs. Tankless systems provide endless hot water on demand.

Older tanks heat and store water constantly, wasting energy. Switching to a tankless model can reduce your utility costs by heating only what you need.

Traditional tanks take up significant space in basements, closets, or utility rooms. Tankless units are compact, freeing up space and giving your home a cleaner, modern look.

Visible rust, corrosion, or leaks indicate your water heater is at the end of its life. Replacing it with a tankless system prevents damage and improves reliability.

How Long Can You Expect Your Tankless Water Heater to Last?

Tankless water heaters are built for longevity, often lasting 20 years or more with proper care, roughly twice the lifespan of traditional tank models.

Their durable components and efficient design help minimize wear, giving you reliable hot water for many years. With regular care, a tankless water heater can provide your home with consistent comfort and fewer replacements.

Unlike traditional units that often fail after a decade, a well-maintained tankless system is engineered to provide reliable service for decades.

Since these systems don’t store water, they are significantly less prone to the rust and sediment buildup that typically shortens the life of tank-style heaters.

Most tankless models are designed with modular parts, allowing for easy repairs and component swaps rather than requiring a full unit replacement when a single part wears out.

Schedule Your Tankless Water Heater Installation With GEM

Upgrading to a tankless water heater is a smart investment in comfort, efficiency, and peace of mind.

Reach out today to schedule your free consultation or chat with our team to learn how a tankless water heater can transform your home’s hot water experience.

What Is a Tankless Water Heater and How Does It Work?

A tankless water heater, also known as an on-demand system, heats water only when you need it rather than storing it in a tank. As water flows through the unit, it is heated instantly, eliminating standby energy loss and providing a continuous supply of hot water. This design is more compact and energy efficient than traditional systems, making it a practical option for many homes.

How long does a tankless water heater installation take?

Most installations are completed in a single day, depending on your home’s size and existing plumbing or electrical setup. Some projects may take longer if upgrades or adjustments are needed. GEM works efficiently and keeps you informed throughout the process.

What type of tankless water heaters does GEM install?

GEM installs high-quality, energy-efficient tankless gas and electric tankless water heaters from trusted manufacturers. These systems are selected for reliable performance and long-term durability. Your technician will recommend options that fit your home’s needs and usage.

Will installation require modifications to my home?

Some installations may require minor updates to plumbing, gas lines, or electrical connections. These adjustments help ensure the system operates safely and efficiently. GEM completes all work cleanly and prepares your system for immediate use.
