Luis was great! Extremely knowledgeable and improved our airflow in our home.
Randy fixed my stairs and 2 guys came and fixed the condensation pipe. All the guys did great work. All my problems are solved.
When our HVAC gave up the ghost last week, I was panicked about having to go without air conditioning for these 80 degree weeks indoors with our two small children and dog. GEM got out for an estimate super fast and was able to book us for system replacement four days later – other companies were scheduling an estimate until three weeks out! Service was quick and efficient, the installers were knowledgeable and kind, and were more than satisfied with the work completed. Thanks, GEM!

Brandon Hawkins handled our house today. Great technician.
Michael Alberto, electrician, was professional, knowledgeable and friendly. He did a fine job.
Gem has installed a new central Carrier A/c system and then, a month later, a new Carrier split system, Tim in sales is fantastic as has been every technician. We have used GEM now for a/c and plumbing (Moen Flo install followed by installation of a water pressure valve). In every case, service has been excellent. They’re expensive, for sure, but they’re quick and efficient and stand behind their work. Worth the extra expense for quality and follow-up when needed.

How to Know When You Need a New Water Heater Installed

When repair isn’t the right answer anymore.

These warning signs are telling you something important. GEM helps Portsmouth homeowners understand the message.

Water heaters have a limited service life. Once yours enters the 10 to 12 year range, efficiency drops and the risk of sudden failure climbs. Replacing before breakdown lets you plan the upgrade on your schedule.

Water pooling around the base of your water heater indicates internal failure. Once a tank starts leaking, it cannot be repaired. Replacing it quickly prevents water damage to your home.

When hot water swings between too hot and lukewarm without pattern, your water heater is struggling. Failing thermostats, sediment buildup, or aging heating elements can all cause this. If basic service doesn’t solve it, water heater replacement in Portsmouth is the answer.

A single repair on a younger system makes sense. But if you’ve called for service multiple times in the past year or two, those costs are adding up. At some point, water heater replacement in Portsmouth becomes the better investment.

Water Heater Installation FAQs

How does GEM determine what capacity water heater my household needs?

We look at several factors specific to your Portsmouth home: how many people live there, number of bathrooms, whether you have high-flow showerheads or standard fixtures, and when your peak usage occurs. A household where everyone showers in the morning has different needs than one where usage is spread throughout the day. We also consider your existing infrastructure since upgrading from a 40-gallon to an 80-gallon tank may require electrical or venting modifications.

Does Rhode Island Energy offer incentives for water heater replacement?

They do, for qualifying high-efficiency models. The program offers rebates that can make upgrading to efficient equipment more affordable for Portsmouth homeowners. GEM helps you navigate the options and choose equipment that qualifies for maximum savings. We’re familiar with the current programs and can guide you through the application process.

I’m not sure what size tank my family needs. How do you figure that out?

GEM’s technicians assess your household’s hot water demands during the consultation. We ask about family size, bathing habits, whether you run the dishwasher and washing machine simultaneously, and what your busiest times are. For Portsmouth’s colonials, farmhouses, and waterfront estates, we often recommend 40 to 50 gallon tanks for families of three to four, but we customize recommendations based on your actual usage patterns rather than applying a one-size-fits-all formula.

What’s the difference between gas and electric water heaters?

Gas water heaters typically heat water faster and cost less to operate if you have natural gas service. Electric models are simpler to install and maintain, and don’t require venting. Heat pump electric models are highly efficient but need adequate space around them. For Portsmouth’s colonials, farmhouses, and waterfront estates, the best choice depends on your existing utilities and installation location. GEM can advise which makes sense for your specific situation.

How long does water heater installation take in Portsmouth?

Most standard tank replacements are completed in two to four hours. GEM’s technicians arrive with a fully stocked truck, so we have the fittings, connectors, and parts needed to handle typical installations without delays. If your Portsmouth home requires modifications like updating old galvanized pipes, relocating the unit, or upgrading electrical service, the job may take longer. We’ll give you a realistic timeframe before we start.
