"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."

Install Boiler questions, answered by experts

Always consult your manual for specific pressure numbers. Many expansion tanks come pre-pressurized at a specific PSI range, anywhere from 12 to 40 PSI, designed for a range of home boilers. You should not have to pressurize an expansion tank yourself, only the boiler system. If your system has a tank that needs to be manually pressurized, this is generally a job for professionals and their tools.

Yes. Boilers need water to run without overheating, also known as dry firing. If you run it without a sufficient volume of water, either because of a burst pipe or a leak, you run the risk of damaging your machine or jeopardizing the safety of your home as a whole. When in doubt, shut off your boiler and repair any plumbing issues before turning it back on. Alternatively, consider installing a low-water cutoff (LWCO) before any issues arise. This gadget will protect your boiler by monitoring water levels and automatically shutting it off if it gets too low. 

The difference between a heat pump and a boiler is simple. A boiler often works with a furnace as part of a heating system. Some HVAC systems also have an AC to cool the home in addition to a boiler. A heat pump is unique as it works as both a heating and cooling system, altering ambient air to a comfortable indoor temperature.

The radiators closest in proximity to the boiler heating system will heat up first. Radiators in rooms farther away from the boiler will take longer to heat up and may be the coolest rooms in the house. The radiator unit itself should heat up evenly; otherwise, there may be trapped air inside it.

You save money on heating oil in a few ways:

  • Make sure your home is well insulated and sealed against drafts and heat leakage.

  • Use a thermostat that’s working properly and calibrated accurately.

  • Increase energy efficiency by insulating your basement and attic.

  • Turn down your thermostat a few degrees.

  • Program your thermostat to lower the heat when you’re not home.

  • Order heating oil during the off-season when prices are likely to be lower.
