Networked ground source heat pumps delivered as a utility
Using the stable heat from the ground, ground source heat pumps outperform individual air source heat pumps on comfort, running costs, emissions, resilience and aesthetics, while costing less per plot to install.
- Designed for the grid you already have - same electrical load as gas heated homes, and around half the demand of individual air source heat pumps, helping avoid costly reinforcements.
- Familiar installation - the network mirrors traditional gas and water infrastructure, so it’s straightforward for site teams and simple to integrate into build programmes.
- Lower risk, better performance - the system is fully owned, operated and maintained by GTC for life - removing long‑term responsibility from the housebuilder.
Integrated technology for smarter developments
Small footprint, extraordinary performance
The Shoebox NX is designed to help housebuilders deliver Future Homes Standard compliant homes while giving homeowners one of the most efficient heat pumps on the market.

- Integrated as standard - Pairing Kensa heat pumps with Passiv Smart Thermostats gives developers a smart‑heating solution with no additional hardware requirements.
- Turn flexibility into savings - New homeowners can benefit from Passiv’s Greener Grid Payments, providing additional value by supporting a greener national grid.

Affordable comfort for warmer summers
Our passive cooling module uses the ground’s naturally cool temperature to keep interiors comfortable during the summer months at a fraction of the cost of AC.
- Low energy cooling - Uses the ground's natural temperature to cool the home without turning the heat pump on.
- Easy compliance - A simple, cost-effective way to meet Part O and Part L building regulations regarding overheating.
- Two-in-one system - Uses the same unit and infrastructure for both heating and cooling - no external units required.
