"Our water heater broke and my neighbor recommended Habitat Heroes. They came the same day, gave a great estimate and had a brand new water heater installed the next afternoon. Very nice work, cleaned up after themselves, didn't make a huge mess. Everything was perfect. Highly recommend. I also hired them for a new bathroom that should be happening spring 2026, will send updates with pics."

Jason the plumber arrived early, concisely explained his planned actions, coordinated with other trades, professionally executed the installation of the tankless heater with minimal disruptions, cleaned up and left a happy customer. Toptec did an excellent job, for my next plumbing issue I will call Jason at Toptec."

"On November 15th Chicago was hit with some extreme wind gusts that caused my water heater pilot light to extinguish. I thought this was a simple reset, but the problem was more complicated. I learned the electrode was defective. Had I undertaken this project as a DIY, I would have spent more time than I would have cared to try to figure out why I could not get a flame for my water heater. I was smart to call Four Seasons. My technician figured out the problem quickly. There are times when calling a professional makes sense. I am not an expert on water heaters outside of knowing how to turn it on, clean it periodically, and knowing when I need a new one. Thank you Four Seasons for responding quickly and bringing me hot water."

Water Heaters FAQs, answered by experts

It is very difficult and dangerous to install your own water heater, so we strongly recommend against tackling this as a DIY project. Not only will you need to wire your water heater, but you’ll also need to connect plumbing to the intake and outlet. Sweating copper pipes and connecting wiring properly are skills most DIYers don’t have, and even if you do feel confident you can do it, working with water and electricity always leaves the potential for electrocution. Hiring a local water heater installer is well worth the investment.

The average lifespan of a water heater is eight to 12 years. If your water heater is approaching its first decade of life and is giving you problems, talk to a plumber about your replacement options.

Keep in mind that certain parts of a water heater, such as the anode rod, may need replacement long before the heater itself. An anode rod often has a lifespan of three to five years.

On average, a tankless water heater should last between 10 and 15 years. Its lifespan will be affected by how much it's used, the effect of weather where your home is on the unit—colder is harsher and will shorten lifespan—and if the heater is maintained appropriately and regularly. There are many signs your water heater needs to be replaced, so pay attention to anything that changes with your heater or hot water.

Homeowners insurance may cover the repair or replacement of a water heater if it's damaged by a covered peril, such as a fire or a burst pipe. However, policies typically do not cover repairs or replacement needed due to normal wear and tear, old age, or lack of maintenance. For these issues, a home warranty or a manufacturer's warranty may provide coverage. While the policy might not pay to fix or replace the malfunctioning appliance itself, it often covers the cost of water damage restoration caused by the faulty water heater. Always check with your insurance provider to understand the specifics of your policy.

One of the primary benefits of a heat pump water heater is how cost-effective it is. How much you save will depend on your water usage and electricity costs. That being said, we can ballpark savings for the average home of between $100 and $500 per year. You can increase that savings rate by researching and applying available energy incentives available in your area. If you really want to focus on cost, consider a tankless water heater.
