SECTA System Installation · Ground Source Heat Pumps · HVAC
We build what SECTA designs.
Engineering-led installation of surface energy collection systems, water-to-water heat pump integration, and wider mechanical services — delivered with commissioning discipline and clear responsibility boundaries.
Install. Commission. Deliver.
A SECTA system only works if the installation respects the design — and the boundaries between surfacing, hydronics and heat pump integration are properly owned.
About GeoTemp
GeoTemp Ltd is the installation and contracting partner for SECTA surface energy systems. We were established to handle what SECTA does not — the physical installation, the site work, the plant room, the commissioning, and the ongoing support.
SECTA, developed by Geo Surface Design Ltd with professional HVAC design authority from tBBC, defines the thermal strategy, the collector principles, the hydraulic arrangement, and the controls philosophy. GeoTemp turns that design into a working system.
01
SECTA installation
Surface collector arrays, Ground Array Accumulator integration, manifold and pipework installation, and hydraulic connection to the building-side plant. Built to the SECTA design, installed by engineers who understand the system.
02
Heat pump systems
Water-to-water heat pump specification and installation, low-temperature heating and cooling distribution, and source-side integration. Sized from the building's thermal requirement, not from a product brochure.
03
HVAC services
Wider mechanical and building services work — ventilation, ductwork, pipework, plant room fit-out, and maintenance. The same engineering discipline applied to conventional HVAC projects.
We do not ask surfacing contractors to become heating engineers — and we do not ask heating engineers to guess the surfacing.
GeoTemp sits at the interface, where the clever work normally gets lost between trades.
An engineered route from design to plantroom.
GeoTemp delivers three connected service areas. Each can be engaged independently or as part of a full SECTA installation package.
- For specifiers: a credible installation partner who understands the SECTA design and can flag buildability issues before they become excavation issues.
- For developers: a single accountable point of contact for the physical delivery — collector, manifolds, accumulator, heat pump, hydronics, and commissioning.
- For surfacing partners: a defined technical boundary, so workmanship and finish quality are protected while the energy installation is owned by competent engineers.
- For HVAC designers: an installation team that understands low-temperature source-side design and won't compromise the heat pump integration through poor installation practice.
What makes GeoTemp different?
The difference is not simply the pipe beneath the surface. The difference is the installation responsibility around it.
Engineering discipline
Every installation starts with the design intent, the thermal duty, and the system boundaries. We don't improvise on site. We build what was specified, flag what won't work before it's buried, and commission what we install.
Clear responsibility
SECTA owns the design. GeoTemp owns the installation. The surfacing partner owns the finish. Each party has a defined scope, and the boundaries are documented before groundworks begin — not argued about after.
Commissioning focus
A system that isn't commissioned isn't finished. We balance flows, verify performance, and demonstrate that the installed system does what the design said it would. The evidence base matters.
Practical engineering
Experience matters. The system has to be buildable, commissionable and understandable after the brochure has gone in the bin. We bring long-standing HVAC and hydronic experience to every SECTA installation.
How we work
From suitability assessment to handover — a defined sequence, not a hopeful process.
01
Suitability assessment
Before anything goes in the ground, we assess whether the site and the building are right for a SECTA system. If SECTA isn't the right answer, we'll say so.
02
Design coordination
We work from the SECTA design package, review for buildability, flag installation issues before they become excavation issues, and coordinate with all parties on sequencing and interfaces.
03
Installation
Collector pipework, manifolds, the GAA, header runs, the heat pump, the hydronic distribution, the controls. Installed in the right sequence, to the design.
04
Commissioning
Flow balancing, zone-by-zone verification, performance demonstration, and controls testing. A system that isn't commissioned isn't finished.
05
Handover and support
As-built drawings, the health and safety file, O&M instructions, and a walk-through with the people who'll run the building. Ongoing support where the client wants it.
The SECTA design defines the system. GeoTemp makes it real. The evidence is in the commissioning, not the brochure.
Developed from building-services experience.
GeoTemp has been shaped from long-standing HVAC, hydronic and heat pump design and installation experience — the practical understanding of what happens when an attractive concept meets real groundworks, real plant rooms, and real commissioning.
The result is an installation approach that respects traditional engineering basics: flow, temperature difference, controls, heat transfer, access, responsibility and maintainability.
New idea, old-fashioned discipline. That combination tends to keep the wheels attached.
Talk to GeoTemp early.
The best time to involve the installation partner is before the external surface design, drainage strategy, and plant room approach are fixed. Early coordination costs less than late excavation — a truth known to every engineer with muddy boots.
