Here’s Why You Should Replace Your Water Heater

You’ve already concluded replacement is necessary. Here’s what acting on that decision delivers.

That aging unit has been burning extra energy for a while. Current water heaters produce the same hot water while consuming less fuel or electricity—utility savings begin the day we install.

The daily uncertainty ends. A new system supplies steady hot water whenever your household calls for it, without the guesswork about whether today is the day it quits.

You’ve probably already sunk money into extending the old unit’s life. Replacement stops that pattern and gives you years of reliable operation ahead.

A modern, efficient water heater contributes to your property’s value. Buyers notice updated mechanicals and appreciate not inheriting a problem.

Michael from Gem Plumbing was here today to do an annual check on our central air conditioning system and mini-split system. He did a thorough check of all the components inside and outside the home. He is very knowledgeable and explained everything very clearly as to what he found and observed on our systems. This service was covered under our maintenance plan with Gem so there was no charge for today. Michael is a really friendly and personable guy and he did a great job at our home.

We had one condenser stop. They came, found an electric problem, sent the electricians in their group, ordered the required electrical panel and we are back up and running.

I was very pleased with GEM plumbing. They came when they said they would and explained everything. I would highly recommend them.
Gem has always been my lifesaver and yesterday they came through again. When GEM came yesterday for the annual boiler cleaning they discovered that my boiler was leaking carbon monoxide gas. It had not been leaking the year before so carbon monoxide leaking from your burner. It’s like a tire that’s going flat in the air is coming out. It only gets worse. They gave me an estimate on replacing it, I did some research and they said that they couldn’t install it the next day. The price was in line with everything I had researched and the Bernar rated very high on Trustpilot as did the warranty. Having worked with GEM before, I trust them and I made the deal. Today two men arrived two more came then the Electrician.They got the old burner out they got the new burner installed. They cleaned up the basement and I now have heat and no carbon monoxide.Thanks for being there again GEM.
John arrived within the time window, was courteous and professional. He explained what he was doing throughout the service call.

Water Heater Replacement FAQs

How quickly can GEM install my new water heater?

Typical replacements take two to four hours. Since you’ve already determined replacement is needed, same-day installation is often available. Tankless conversions require additional time if venting or gas line work is involved.

Should I choose a tank or tankless water heater?

That depends on household usage, available space, and budget. Tank units cost less initially and serve most homes well. Tankless models have higher upfront costs but deliver unlimited hot water and typically last longer. GEM’s plumbers can discuss what fits your Needham home.

What rebates are available through Mass Save?

Mass Save provides rebates on qualifying high-efficiency water heaters, including heat pump models. GEM helps Needham homeowners determine which equipment qualifies and assists with rebate paperwork.

Does GEM handle removal of my old water heater?

Yes. Disconnection and removal are part of every replacement. You don’t need to arrange disposal separately.
