Oil Tank Removal in Merrimack County NH
Hooksett and Dunbarton touch Manchester. Both are Merrimack County. That surprises people who have lived here for years, and it is the sort of thing that matters at exactly the wrong moment.
The county runs 29.9% oil heat across 62,719 households, so 18,755 tanks in service. That sits between Hillsborough and Rockingham rather than at either extreme.
The County Line Nobody Notices
You can drive north out of Manchester and be in a different county before the houses change character at all. Hooksett in particular reads as an extension of the city and is administratively nothing of the sort.
For the physical work this changes nothing. For anything involving records, a deed, a title search or an old plan showing a tank, it changes where you look. A buried tank question that goes to the wrong registry comes back clean for the wrong reason.
Concord Is Its Own Case
The state capital runs about 16.5% oil heat, well under the county and less than half of Rockingham. It has gas coverage and a housing stock that has been worked on continuously because of what the city does for a living.
That figure comes from the five-year Census estimates rather than the one-year series used elsewhere on this page, so treat it as the shape of the thing rather than a number to put next to the others.

Bow, Dunbarton and the Rural North
Outside Hooksett and Concord this is low-density country, and oil heat holds up accordingly. Larger lots, longer driveways, outdoor tanks more often than basement ones, and the occasional property where the nearest gas main is not in the same town.
Access is usually good. What you trade for it is distance, and sometimes a driveway that a loaded truck should not be asked to turn around on in March.
Grant Coverage Here
Same statewide terms: up to $4,000 toward an aboveground replacement, up to $4,500 toward an underground removal, income-qualified, pre-approved before work starts. The process.
