Geothermal cooling & heating in Karachi
In Karachi the ground sits at about ≈26 °C all year while summer air reaches 38–42 °C with high humidity. 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 10–14 °C.
Why Karachi homes choose it
Karachi's problem isn't peak temperature, it's duration and humidity — cooling runs nearly year-round, so running cost dominates the decision. That's exactly where a COP 5–6 system compounds against K-Electric tariffs faster than anywhere else in Pakistan.
What we design for in Karachi
Kelvin's starting design assumptions for this city — confirmed per site by survey before drilling.
| Stable ground temperature | ≈26 °C |
|---|---|
| Design borehole depth | 40–55 m |
| What we drill through | Sandy strata with saline groundwater — loops grouted and sleeved against corrosion |
| Summer design condition | 38–42 °C with high humidity |
| Winter design condition | 10–14 °C |
| Distribution utility | K-Electric |
Installing in Karachi
Project-basis: surveys scheduled in batches. Commercial enquiries prioritised. 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.
