Seeking repair of a leaking water supply connection and shutoff valve to a pedestal sink along with a leaking faucet handle, I entered info on GEM’s website this morning. I received a prompt callback from Gena who was friendly and helpful. An appointment was able to be arranged for about 6 hours later. The plumbers Joe and Baxter arrived on time and took care of all the problems in a professional manner leaving their work area and sink perfectly clean. This was the first time working with GEM. I was quite impressed and would certainly seek their help should the need arise.

In a world where you call HVAC companies and either get no answer, an AI receptionist or a human who takes all your information just to tell you they can’t service you until next week, these guys were a breath of fresh air! Same day service. Fair price. Incredibly kind people from the receptionist to the service worker. Thank you guys!


How to Know When You Need a New Water Heater Installed

Here’s what to watch for with an aging water heater.

Johnston homeowners should pay attention when these issues appear. GEM can determine whether replacement is your best option.

Water heaters don’t last forever. Once yours reaches 10 to 12 years, components wear out and efficiency drops. Replacing before failure lets you plan the upgrade instead of reacting to an emergency.

Water or dampness around your water heater signals trouble. Even small leaks indicate tank corrosion that will only worsen. Catching this early and scheduling replacement prevents water damage to your home.

If your household used to have plenty of hot water but now runs out quickly, the tank is losing capacity. Sediment buildup and aging components reduce how much hot water your system can deliver. New water heater installation in Johnston restores the supply you need.

An aging water heater works harder to heat the same amount of water, using more energy in the process. If your bills have increased without other explanation, your water heater may be the reason. A new, efficient system brings those costs down.

We Install All Types of Water Heaters in Johnston

Modern water heaters come in several varieties, each designed for specific household needs and priorities.

GEM helps Johnston homeowners navigate these options and install the best system. Here’s what we offer:

Tankless technology heats water on demand rather than storing a heated supply. When you open a faucet, cold water flows through a heating element and emerges hot instantly. This eliminates standby energy loss while providing unlimited hot water. GEM installs tankless water heaters in Johnston for homeowners seeking efficiency and endless supply.

Conventional tank systems maintain a reservoir of heated water ready whenever you need it. These reliable, proven systems offer affordable installation and dependable daily performance. Most Johnston families find tank water heaters meet their needs effectively without unnecessary complexity.

Hybrid units extract warmth from surrounding air to heat water, achieving efficiency far beyond conventional heaters. They keep a tank of hot water available while dramatically reducing energy use. Johnston homeowners focused on long-term savings and rebate eligibility often choose hybrid systems. GEM installs these throughout town.

Water Heater Installation FAQs

Are high-efficiency water heaters worth the extra cost?

For most Johnston homeowners, yes. High-efficiency models cost more upfront but reduce monthly energy bills, often paying for themselves within a few years. Heat pump water heaters in particular can cut water heating costs by 50% or more compared to standard electric tanks. Combined with Rhode Island Energy rebates, the net cost difference shrinks significantly while the savings continue for the life of the equipment.

Can GEM handle water heater emergencies in Johnston?

Yes. We provide 24/7 emergency service throughout Johnston and the Providence metro area. If your water heater fails unexpectedly, leaks, or poses a safety concern, call us immediately. Our technicians can respond quickly to assess the situation and get your hot water restored as soon as possible.

Should I get a gas or electric water heater for my Johnston home?

That often depends on what’s already in your home. If you have natural gas service and existing gas lines to your water heater location, a gas unit typically offers faster recovery times and lower operating costs. If you’re electric-only, an electric water heater or heat pump model avoids the expense of running new gas lines. GEM evaluates your Johnston home’s infrastructure and helps you choose the option that makes practical and financial sense.

What maintenance does a water heater need?

Regular maintenance includes annual flushing to remove sediment, periodic anode rod inspection, and checking the pressure relief valve. These simple tasks extend equipment life and maintain efficiency. Many Johnston homeowners find it easier to have GEM handle maintenance through our Home Comfort Club, which includes scheduled service visits and priority scheduling if problems arise.

What rebates are available for water heater installation in Johnston?

Rhode Island Energy offers rebates on qualifying high-efficiency water heaters, including heat pump models that can significantly reduce energy costs. The rebate amounts vary by equipment type, and eligibility requirements change periodically. GEM stays current on available incentives and helps Johnston homeowners identify which models qualify. We can also assist with the paperwork to make sure you capture available savings.
