Here’s Why You Should Replace Your Water Heater

Water heaters don’t improve with age. Here’s what a new one actually provides.

Modern water heaters use less energy to heat the same water. That efficiency shows up on your utility bills every month.

Temperature fluctuations and recovery delays disappear with a new system. Hot water works when you need it.

Professional installation means equipment that runs better and lasts longer. You’re paying for work done right.

Updated mechanical systems matter to buyers, especially on the Cape where inspections can make or break deals. A new water heater removes a concern.

The service was good.Aiden was very good. It’s just they said they were on there way 2hrs and30 min they finally arrived. Waited all afternoon
The 2 service men were on time, assessed the problem, diagnosed the issue, came up with a plan and offered several solutions for fixing our mini split. They took pictures, tried clearing out mice debris , attempted to get the outside machine to work ( apex 2 hours) Alas a no go, so we decided to scrap it and go with baseboard heater for the room over the garage. Up front information and pricing , no nonsense. Affable techs and so far great service.

I was thoroughly impressed with the superb HVAC maintenance service I received from David Santiago and trainee, Kevin today! Before David and Kevin arrived I was very disappointed with having had my original service date rescheduled to what I thought were spurious reasons? In fact David and Kevin arrived after the designated rescheduled date and time today. GEM's communication was excellent throughout and their people seemed genuine and concerned. When David and Kevin arrived it turned the whole situation around. They could not have been more professional and knowledgable! I am now firmly committed to GEM and their Home Comfort maintenance program.

We just had our heating system replaced. We went from forced hot water system to a central heating and air conditioning system done by GEM plumbing and heating company We had Omar and Michael work in our home for 5 days they installed all the ductwork, the furnace and the condenser. These guys were very professional, kind, clean and informative throughout the whole install every day they explaind what they did and what is the expectation for the next day. Today was the last day they walked me through the whole system, how to change the filter how to operate the new thermostat and what to look for when things are not working properly. I say thank you to the whole team from planing to done, all went great to expectations

Water Heater Replacement FAQs

Is a tankless water heater worth it for my Falmouth home?

Tankless units make sense for certain situations. They’re particularly appealing for seasonal properties since they avoid standby energy loss when the home sits empty. They also work well in tight spaces. Our plumbers can evaluate whether tankless fits your needs.

What efficiency ratings should I look for?

Look for a high Uniform Energy Factor (UEF) rating, which measures how efficiently the unit converts energy to hot water. Heat pump water heaters and tankless models typically score highest. Mass Save offers rebates on qualifying efficient equipment.

Can you install a water heater in an older Falmouth home with limited space?

Yes. We’re experienced with the space constraints common in Cape Cod’s older and cottage-style homes. Tankless units mount on walls and work well in tight spots. We assess your available area and recommend options that fit.

How often should I maintain my new water heater?

Annual maintenance is recommended. Service typically includes flushing the tank, inspecting the anode rod, and checking connections. For coastal properties, more frequent anode rod inspections may be advisable.
