"Badly. 2 different techs came out. We paid for a Premium service and within hours of that tech coming out, our burner stopped working completely. Mind you there is a snowstorm. They sent out a new technician and he saw nothing wrong with the system at all. He said we had no oil. He said there was no footprints even going to my intake on the side of my house. It had snowed 2 times since oil was delivered, so that makes no sense. The tech was absolutely sure we had no oil. 3 days since the first visit now and we had oil delivered and the tank filled completely. Only 150 gallons went into my 250 gallon tank. So that's wrong. And I look at the front of my furnace and now see a slow drip from the front underneath the box on the front of the furnace. First tech recommended i replace the electrodes but said it didnt need it. Second tech didnt even mention that and said our system was good. Now, I will have to contact Angi for support and my insurance company. TERRIBLE TERRIBLE TERRIBLE"

FAQs for boiler installation projects in Nashua, NH

The average cost to install a new water heater is around $1,300, but you can expect to pay between $875 and $1,750, depending on the kind of water heater, the size of the unit, and the professional chosen to complete the work. Tankless water heaters can push your price higher, as installation is more complicated, with prices as high as $3,500. The location and accessibility of your water heater will play a role in the project cost, as those sitting in tight spaces like a crawl space will drive up your labor costs.

Yes, most states require plumbers to be licensed, and for good reason. Hiring an unlicensed plumber could lead to poor quality work, costly future expenses, and potential code violations. 

As you browse our pro listings, take note of the “Angi Approved” badge. Angi Approved businesses meet our standards for certification which include: 

  • The owner, principal, or relevant manager passed a criminal background check

  • Required to have applicable state and local licenses

  • Maintain an average star rating of 3.0 or better on our network, if they have at least one review

  • Paying to advertise their services

  • Meeting any other eligibility criteria required by Angi

Keep in mind licensing is different from certifications. A license is a legal requirement to operate a business, while certifications are voluntary.

It usually takes a professional water heater installer between two and three hours to remove an existing water heater and install a new tank heater. However, it could take four to five hours if they have to work in a small utility closet or another tight area, like a crawl space. Tankless water heaters have a more complicated installation process, so they will take a bit longer. Additionally, a gas water heater requires a connection to a gas line, and that alone can add about an hour to the installation timeline compared to installing an electric water heater.

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 cost to hire a plumber is around $100 an hour but can vary between $45 and $200 an hour depending on the plumber’s experience and the repair that you need. It’s also important to note that these prices can go up on holidays, and emergency plumber rates average $150 per hour, in addition to a flat-rate trip fee of $100 to $350
