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.

Lindsey Desrosiers
Edgar did the initial inspection and application. He was very friendly and pleasant. He listened to our concerns and worked with us. Bruno and his team installed our mini splits. They were very efficient and friendly as well. They even worked around our son’s nap schedule. They made sure everything was how we liked it before proceeding to something else and they gave their honest opinions.
I highly recommend going through GEM, even if they are a little pricey, their financing programs are accommodating.

This guy is amazing Furst of all he listens and secondly , he doesn’t mind a little extra work to solve a problem . With his partner Gennaro they explored every aspect before discovering
G what had not been done to my setup. And after correcting that , they did a review of Step 1 EXPLAINING OPERSTION . Each new install should start with this approach by Joshua and Gennaro.

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.
