"We met Dan months before the project was scheduled to start and he knew our deadline was 7/9 when our first weekly vacation renter was due to arrive. Our main issues were: He was a week late starting Didn't show up on several days (had to take his son to get his COVID shot, several days it was too hot, heavy traffic, etc) Ignored my detailed instructions/drawings and we lost time because he plumed a double vanity for only 1 sink, told us we could buy any standard shower door from Lowe's only to learn AFTER the shower had been framed that it required a custom built door, forgot to tile the accent color stripe in the shower, miscalculated the amount of shower tile needed requiring me to drive 3 hours RT to purchase extra tile and deliver it to him. Skim coat on the ceiling was done poorly, the door to the bathroom didn't open all the way so we had to hire someone after Dan left to shave it down for us. He was supposed to finish by July 9th and didn't finish until Sept 9th!!!! had to give renters $3000 off because they had no toilet or shower. I split the difference with him and took $1500 off his bill and he was not happy. I should have taken the entire amount off. He might be OK for smaller jobs, but he is not focused enough and doesn't work a full day (usually 8 AM -1 PM) or even a full week. If he takes work outside of NH, he should have his plumbing/electrical license so he doesn't have to rely on outside contractors. We suffered because he didn't hold ME licenses and wasn't well connected w/ local contractors in ME."

"I signed a contract on the first week of June to have PIC Home ?Pros? remodel 3 bathrooms. They stayed for a week in the middle of September, and stopped coming, leaving a vanity in one bathroom, and a shower door in another bathroom completely uninstalled. On the last day here, I was told shower door still has not been manufactured yet, but would take a couple of weeks. They told me that it would cost $150 to have them come back to finish installation, even though contract was for them to complete the work. They ignored my emails to them, so after waiting for 3 weeks and receiving response to my email, I called them, and was told that the shower door is not ready, and even though it?s been 4 months since it was supposed to be ordered, there is still no ETA. I asked that they come back to install the vanity, since we still have no sink in one bathroom. I was told that would cost another $650 to come back and install it. They will work until they are paid in full, then abandon you. "

Water Heaters questions, answered by experts

No. Expansion tanks must be installed on the supply side (where heated water flows out) of the boiler. There’s also a list of other requirements for most boilers, including being above the pressure relief valves, being on the inner side of any circulator, and more. Your installation manual should have more information on expansion tank installation requirements and what sort of tank the system is made for.

The cost to replace a water heater depends on the type you choose (tank versus tankless) and the fuel type. You can expect to pay anywhere from $880 to $1,780 for a one-to-one replacement. If you’re switching from one type or energy source to another, labor costs will rise significantly for the extra amount of work. 

Your water heater's age can affect your homeowners' insurance policy. Many policies will ask how old the heater is when you first apply for a policy—and they may make you replace a model that's over 10 years old. 

Even if your policy permits you to have an older heater, it may significantly reduce the amount of protection available. If an older water heater suddenly leaks and causes damage to parts of your home, your policy may not cover it.

Every type of water heater has its advantages and disadvantages. Understanding those can help you decide the best type for your situation and budget. 

Pros

  • Safer than gas or propane

  • Doesn’t require extensive venting systems

  • Lower upfront costs

  • Simpler to operate

  • No pilot light

  • Easier installation

  • More efficient heating than gas models

  • Available as point-of-use (POU) and whole-house units

Cons

  • Slower to heat water

  • Longer recovery time

  • Possibly higher operating costs

  • Doesn’t work during a power outage

  • Costs can increase without a 240-volt connection

The standard copper wire gauge to use with any 30-amp circuit is a 10-gauge wire. The National Electric Code specifies a 10-gauge wire with appliances like water heaters running on 30 amps. If you try to use a smaller gauge wire, such as a 12 gauge, with a 30-amp breaker, you run the risk of the wire overheating and melting or causing a fire. Because of the safety hazards, the gauge of the wire is not an area to try to cut costs when connecting a 30-amp breaker to a water heater.
