Here’s Why You Should Replace Your Water Heater

You already know your water heater needs replacing. Here’s what you gain by moving forward.

Your old unit has been wasting energy. New water heaters use less fuel or electricity to produce the same hot water, meaning lower bills starting immediately.

No more wondering if today is the day it finally quits. A new system delivers consistent hot water whenever your household needs it.

You’ve likely already spent money trying to extend its life. A new water heater ends those recurring repair expenses.

A modern, efficient water heater adds to your home’s value. Buyers appreciate systems that won’t need replacement anytime soon.

Don’t Trust Your Home & Family to Just Anyone.

Peter Alley
I had a clog in my kitchen sink drain and it was a mess. Colin was very respectful of my property and worked very efficiently. He cleaned up after the work was accomplished, the area was impeccable. I have used Gem in the past, and would not hesitate to recommend them in the future.
Billy Hayhurst
Nicole was great, very nice and knowledgeable!
Paula Costa
Eric Governor from GEM came to my house today. I was very overwhelmed with the electrical issues I was having and he took his time explaining everything to me and what my options were. He didn’t leave until I understood what was needed. They were very nice and made me feel comfortable.
Carol A. Lockwood
Chris was on time👍 polite, friendly and helpful. He was efficient as well. I plan on calling Gem P&H again when I need you. Thanks for your service.
Eamon Concannon
Excellent service. What i believed was a small electrical issue, turned out to much more involved. Dory and Kevin spent hours "in surgery" correcting faulty wiring and got my system working again.
Very greatful. I found my new mechanical team.
Mario Cirillo

sally Leathers
The best! They found some discounts for me and were more reasonable than other companies. They cleaned everything up were efficient and really nice. I’m so happy with my new boiler.
Christine McCarthy
On Oct. 16 the heat in the house still wouldn’t work so GEM came out to find the problem. Harrison arrived at 9:00 and spent all day working on a solution. He kept me informed on what was happening all along the way. It turns out that it was several problems all related and by the end of the day another part had to be found. The next day Harrison and Erin were there bright and early and with the new part. Even with the new parts things were still not working right, so they contacted the tech team at Bryant headquarters and they were stumped. But Harrison and Erin solved the problem and now we have heat. They were terrific, very hard working, knowledgeable and professional and friendly. I’m very pleased.

We are very happy with our service. We had a leak that caused our water to be shut off. In no time Gem had it all figured out. Thank you Cesar and Alex. We really appreciated the great follow through. Very clean job. Water being put back on was amazing. They also handled all the ground work to make sure everyone was notified and they also pulled all the permits.

Water Heater Replacement FAQs

How quickly can GEM install my new water heater?

Most replacements are completed in two to four hours. Since you already know you need a new unit, we can often schedule same-day installation. Tankless systems may require additional time if modifications are needed.

Should I choose a tank or tankless water heater?

It depends on your household’s usage, available space, and budget. Tank water heaters cost less upfront and work well for most homes. Tankless models cost more initially but provide endless hot water and last longer. GEM’s plumbers can help you decide what makes sense for your Waltham home.

What rebates are available through Mass Save?

Mass Save offers rebates on qualifying high-efficiency water heaters, including heat pump models. GEM helps Waltham homeowners identify which models qualify and assists with the rebate paperwork.

Does GEM handle removal of my old water heater?

Yes. We disconnect and remove your old unit as part of every replacement. You don’t have to worry about disposal.
