Geothermal Heat Pumps in Nova Scotia
Regular maintenance keeps your heat pump running efficiently, protects your warranty, and helps you avoid costly repairs. Book a professional tune-up with Nova Scotia’s cold-climate heat pump specialists.
A heat pump that isn’t serviced loses efficiency every year, often without homeowners noticing until the bill or a breakdown makes it obvious. Nova Scotia’s coastal air and long heating season mean coils, filters, and outdoor units need more attention than in drier climates. One seasonal tune-up a year is usually enough to keep your system at peak efficiency and protect your warranty.

Where the Heat Actually Comes From
A few metres below the surface, the ground in Nova Scotia sits at a fairly constant temperature all year, roughly 8–10°C regardless of whether it’s a July afternoon or a February cold snap. That stability is the entire point.
- In winter, fluid circulating through the buried loop absorbs low-grade heat from the ground and carries it to a heat pump indoors, which concentrates it and delivers it to your home through ducts or radiant distribution.
- In summer, the process reverses. The system pulls heat out of your home and rejects it into the ground, which is cooler than the outside air, so geothermal cooling is unusually efficient. Many systems also divert that recovered heat to preheat your domestic hot water at the same time.
Unlike an air source heat pump, there is no outdoor unit. Nothing to defrost, nothing exposed to salt air, nothing to clear snow off, nothing for the neighbours to hear. Everything sits indoors except the loop, which is buried and effectively maintenance-free.
Efficiency is typically expressed as a coefficient of performance of 3 to 5, meaning three to five units of heat delivered for every unit of electricity consumed, and critically, that figure holds steady through the winter rather than declining with the outdoor temperature.
The Four Ground Loop Types and Which Suits Nova Scotia Properties
The loop is where most of the cost and nearly all of the site constraints live. Choosing the right one is what the site assessment is for.
1
Vertical Closed Loop
Boreholes drilled straight down, typically 45–150 metres deep, with loop pipe installed and grouted in place. Needs very little surface area.
- Works on most suburban lots
- Minimal disruption to landscaping
- Deeper ground is more thermally stable
- Highest cost per unit of capacity
- Requires drilling rig access to the site
2
Horizontal Closed Loop
Loop pipe laid in trenches roughly 1.5–2 metres deep across an open area of the property, then backfilled.
- Substantially cheaper than drilling
- Needs roughly ¼–½ acre of clear land
- Must avoid septic fields, wells and mature trees
- Significant surface disruption during install
- Ideal for rural properties and new builds
3
Pond or Lake Loop
Coiled loop pipe submerged and anchored in a sufficiently deep body of water on your own property.
- Often the cheapest option available
- Water must be deep enough not to freeze through
- Minimal excavation required
- Environmental approvals apply
- Only viable for waterfront and pond properties
4
Open Loop / Standing Column
Uses groundwater from a well directly rather than a sealed loop, then returns it to the ground or a discharge point.
- Can use an existing drilled well
- Very efficient where water quality is good
- Requires sufficient sustained well yield
- Water chemistry and iron content matter
- Not suitable near coastal saltwater intrusion
Why Nova Scotia Homeowners Choose Mada for Geothermal
Geothermal is the largest heating investment most people will ever make. Here’s how we approach it differently.
We'll Tell You Not To
A large share of geothermal enquiries end with us recommending a cold-climate air source system instead. We install both, so we have no reason to steer you toward the bigger invoice, and a homeowner sold an unsuitable $35,000 system is a problem for years.
Accurate on Rebates
We won't promise you a geothermal rebate that doesn't exist. Several contractors in this province are still advertising programs that closed or never applied to ground source in the first place. That's how homeowners end up with a funding gap they didn't budget for.
Proper Load Calculation
Room-by-room heat load analysis before loop sizing. On a geothermal project, sizing by square footage isn't just sloppy; it's expensive because the loop is the part you can't cheaply change later.
Local Team, Local Accountability
Halifax-based and working across the province. When you call back about the system in year seven, you're talking to the people who installed it, not a national call centre.
Find Out If Your Property Suits Geothermal
Every geothermal project starts with the ground, not a brochure. Book a free site assessment, and we’ll tell you what your property can actually support, what it would cost, and honestly whether a cold-climate air source system would serve you better.
