"The installation went well. The crew arrived on time and completed the job on schedule. Included was a one year guarantee on labor and 5 years on the unit. The price was fair. We will use the company again for future jobs."

"Kevin was great! The rest of the company not so much. Kevin diagnosed the problem immediately as the thermostat, had a replacement in the truck, and completed the installation of the new unit quickly. He showed me how to program the updated version, and everything seemed to be fine - until the next morning. Turned out the replacement was defective. When I called, I was told that they might not be able to get back to me that day, but Kevin interrupted his schedule to come back and put in a new (and working) unit at no charge."

"Vincent, the technician, arrived wearing a mask (pandemic times), observed social distancing, and was skillful and quick at performing the job. He took the time to explain the new thermostats to me and set them for me after I requested it. He cleaned up, left no mess. NH Ross installed my new boiler which is working great!"

Install Boiler questions, answered by experts

If you have a closed-system boiler that requires an expansion tank, you cannot safely operate it without one, as this risks extensive damage or even explosions. You must find a way to make room for the installation. Options include repositioning the boiler, rerouting the boiler piping to a more open area, or performing minor remodeling to create the necessary space. If you are unsure whether your boiler needs an expansion tank or how to best accommodate one, it's recommended to have a local heating service professional assess the situation. They can confirm the requirement and suggest the most practical solution.

You can save money on heating oil through a combination of improving home efficiency and smart purchasing strategies.

Home Efficiency and Usage:

  • Improve Insulation: Ensure your home, especially the basement and attic, is well-insulated and sealed against drafts to prevent heat leakage.

  • Manage Your Thermostat: Use a properly calibrated and programmable thermostat. Lower the temperature by a few degrees, particularly when you are away from home or asleep.

Purchasing Strategies:

  • Buy in the Off-Season: Order heating oil during the summer months when prices are generally at their lowest. This strategy is most effective if you have a large primary tank or a separate storage tank to accommodate bulk deliveries.

  • Consider a Delivery Contract: Some companies offer contracts with a set price for the term. This can lead to savings if market prices for oil increase, but you might pay more if prices drop.

No, there isn’t always water in radiators. In a one-pipe system, water is constantly circulating from the boiler to the radiators and back. In a two-pipe system, water travels through two separate channels: one that goes to your radiators and one that returns back to the boiler so it can heat up again.

Professionals can recommend efficient layouts or appliances and ensuring regulatory compliance.

Using heating oil to heat your home has its advantages, but it also has its disadvantages. 

Consider these drawbacks before installing a heating oil system:

  • Heating oil prices fluctuate frequently

  • Risk of oil spills or leaks

  • Produces more air pollution and soot compared to a gas furnace

  • Regular maintenance required for equipment

  • Need to reorder heating oil consistently to avoid running out
