New Brunswick sits in one of the most favourable ground-source heat pump climates in eastern Canada. Bedrock is accessible across most of the province, heating-degree days run roughly 4,000–4,500 annually, and oil heat remains common — so switching to geothermal cuts both a large fuel bill and significant carbon output. Our directory lists 17 verified geothermal contractors serving Moncton, Fredericton, Saint John, and surrounding communities, with the NB Power Total Home Energy Savings rebate of $2,000 available right now for qualified installations.

New Brunswick geothermal incentives in 2026
NB Power runs the province's main residential energy efficiency programs through saveenergynb.ca. Oil heat is widespread in New Brunswick, which makes geothermal installations eligible for the federal Oil to Heat Pump Affordability Program on top of the provincial rebate. The two programs can stack for oil-heated homes.
- NB Power Total Home Energy Savings Program — $2,000 rebate for geothermal heat pumps (existing homes). The ground-source heat pump must carry ENERGY STAR certification or appear on NRCan's list of eligible high-efficiency GSHP models. Available to NB Power residential customers. Program details and how to apply →
- NB Power New Home Energy Savings Program — $2,000 for geothermal in new construction. Same rate as the existing-home stream; applies to new residential builds served by NB Power.
- Oil to Heat Pump Affordability Program (OHPA) — up to $15,000 for oil-heated homes. Federal program, co-delivered in New Brunswick with a provincial top-up. Ground-source heat pumps are eligible (must meet CSA C448 standard). Household income must be at or below the area median; home must currently be heated with oil. NB's OHPA registration window closes June 30, 2026 — installations must be complete by March 31, 2027. Speak with a participating contractor to confirm your eligibility before the deadline.

Note: The Canada Greener Homes Grant and Canada Greener Homes Loan are both closed to new applications. Check our permits and incentives tool for current program status.
New Brunswick geothermal regulations & well-drilling rules
Geothermal drilling in New Brunswick is governed primarily by the Clean Water Act, S.N.B. 1989, c. C-6.1 and the Water Well Regulation, N.B. Reg. 90-79, which require all well construction to be carried out by a licensed Well Contractor (annual permit, issued by the Department of Environment and Local Government) and a licensed Well Driller (annual permit, requiring a certificate of qualification under the Apprenticeship and Occupational Certification Act).
There is an open regulatory question specific to closed-loop geothermal systems: N.B. Reg. 90-79 defines a "well" as an artificial opening made to obtain water. A sealed closed-loop borehole from which no water is extracted may not fall squarely within that definition. In practice, geothermal contractors in New Brunswick — including established operators in Petitcodiac — obtain standard Well Contractor and Well Driller permits and treat the regulation as applying to all borehole work. A review of the Clean Water Act is underway; proposed amendments had not been published as of mid-2026, and no official guidance document resolving the closed-loop question has been issued.
Open-loop GSHP systems that withdraw and reinject groundwater more clearly fall under the regulation and may require additional approval under the Clean Water Act depending on extraction volume and proximity to watercourses. A water quality test ($122 + HST) is required within 12 months of any new well completion.
NB Power's rebate programs require CSA, HRAI, or IGSHPA certification of the installing contractor as a program condition — this is a rebate eligibility requirement, not a provincial law. Use the permits tool to check current permit requirements for your location.
New Brunswick climate and ground conditions
New Brunswick has a humid continental climate inland and a modified maritime climate along the Bay of Fundy coast. Heating-degree days range from roughly 4,000 in coastal areas to 4,500+ inland and in the north. Summers are warm enough that a geothermal system provides meaningful cooling benefit, not just winter heat.
Ground temperatures at loop depth (typically 120–180 m for vertical closed-loop in NB bedrock) run around 8–10°C — enough to deliver efficient heating even during the coldest Atlantic winter periods. The province has diverse geology: sandstone and sedimentary formations are common in the Moncton area and Fundy coast, while granite and metamorphic bedrock appear in parts of central and northern New Brunswick. Loop design varies by site; a qualified contractor will conduct a site assessment before recommending vertical versus horizontal installations.
Oil heat accounts for a significant share of residential heating in New Brunswick — higher than the national average — which makes the payback calculation for geothermal particularly strong here. Homes currently heating with oil and switching to geothermal may qualify for the OHPA program on top of the NB Power rebate, compressing payback period considerably.
