"I called in the early evening and David called me back within 5 minutes. I explained the problem with my central AC not working and he was here the next morning. David diagnosed the problem and gave me a very fair price for the repair. He had the part on his truck and had the AC running again within 45 minutes of his arrival. David seems to be one who is genuinely pleased to help you. He was very prompt with his arrival time and extremely courteous. He definitely has a new customer for AC and plumbing work."

"I was thoroughly pleased with the installation of my new kitchen faucet. What I liked is that they went above and beyond. There were other things in the house that needed attention and Kyle changed did a "wellness" check around the house, the bathrooms and found that the faucet to the outside of the house needed updating. I wills say that their price was a little high but for my peace of mind, it was worth it. Within 5 days of my work being done, I recommended them to a co-worker who needed a hot water heater repaired and they are satisfied with that work too. Yes, I will call on InstaPlumbing again."

"Outstanding professional service all around by N & J Plumbing from the moment I was contacted by Nick on a Saturday (when my water heater began leaking), who initially guided me on the phone as to the actions I needed to take to gradually stop the leak - until the replacement of my water heater on Monday by Nickâ s team."

Water Heaters FAQs, answered by experts

Flushing biannually, checking the anode rod, and temperature settings maximize equipment lifespan while reducing surprise costs.

It takes between one and three hours to replace a hot water heater element, depending on whether you hire a pro or do the work yourself. For example, a professional plumber with all the necessary tools and experience can often finish the job in one to two hours, whereas DIY will take two to three hours because it'll involve more preparation and troubleshooting.

Yes, you can replace a current tank water heater with a tankless model or vice versa. If you’re maintaining the same fuel source—gas or electricity—the switchover should be smooth. A conventional tank requires open floor space, while a tankless model can be wall-mounted. If you’re switching to a tank water heater, you might need to clear space for it. Gas-powered tankless water heaters need a large volume of gas when they start running to heat the water instantly. You might need to increase the size of the gas line when going from a tank to a tankless model.

If you are having trouble determining the right breaker size for your water heater, it is a great idea to contact an electrician near you to help. They can help you determine the best option for your home and install the circuit breaker for you, ensuring that you have all the proper permits and that your circuit breaker won’t overload, which could lead to fire and other damage.

It’s important to find the type of water heater that fits your needs and budget. Depending on the type of water heater, size, brand, and the type of energy you use to heat the water, costs range from a few hundred dollars to several thousand. Some of the most common types of water heaters include:

  • Electric: $600–3,500

  • Gas: $700–$2,700

  • Propane: $700–$2,500

  • High efficiency: $1,500–$3,000

  • Indirect: $1,200–$3,500

  • Hybrid heat pump: $1,200–$3,500
