Geothermal cooling & heating in Islamabad
In Islamabad the ground sits at about ≈22–23 °C all year while summer air reaches 40–43 °C. A Kelvin system moves your home's heat into that ground instead of the afternoon air — so it does the work of your entire AC bank on roughly half the electricity, and reverses to heat the house when winter drops to 1–4 °C.
Why Islamabad homes choose it
Islamabad is the strongest heating case in the country: real winters in F-, E- and DHA sectors mean gas heating bills and load-shedding both bite. A reversible geothermal plant covers a 40 °C June and a 2 °C January on the same machine.
What we design for in Islamabad
Kelvin's starting design assumptions for this city — confirmed per site by survey before drilling.
| Stable ground temperature | ≈22–23 °C |
|---|---|
| Design borehole depth | 50–70 m |
| What we drill through | Clay over sandstone and gravel beds — slower drilling, deeper loops |
| Summer design condition | 40–43 °C |
| Winter design condition | 1–4 °C |
| Distribution utility | IESCO |
Installing in Islamabad
Survey and install by travelling crews from Gujrat; add 1–2 days to scheduling. Drilling needs about one car-parking space of access for 2–4 days, then we restore the surface. A full installation — loop, plant room, indoor units or ducting, solar canopy — typically completes in 2–3 weeks. Taking pre-bookings now · first installations October 2026.
