Home/Aerothermal/Aerothermal System Design
Aerothermal · System design
Aerothermal system design in Valencia — sized to your home, not to a brochure.
Heat-load calculation, hydraulic design and emitter planning before any equipment is ordered — so the system you buy is the system your home actually needs.
Is this you
Order a design first if…
You've received wildly different quotes for the same house
Your current system short-cycles or never quite heats
You're planning a renovation and want systems decided early
Your home is unusual — old walls, extensions, tall spaces
You want to compare underfloor and radiators on numbers
You'd rather decide on calculations than promises
In plain terms
Design decides efficiency.
Most underperforming heat pumps were never designed — just bought. VELTORRA starts with your home's fabric, orientation and habits, then sizes the unit, storage and emitters as one balanced scheme you can verify.
Credited in full against your installation
No catalogue guesses, no oversizing
From survey to a documented scheme
Surveys across the Valencia metro area
How it works
From survey to a scheme you keep.
Survey
Measurements, fabric review, your habits and priorities.
Calculation
Room-by-room heat load and hot water demand.
Scheme
Equipment selection, hydraulics and emitter plan.
Handover
A documented design you can build with us — or keep.
Why VELTORRA
What the design settles — on paper, before money moves.
Heat-load calculation
Room-by-room load from fabric, glazing and orientation — with Valencia climate data.
Hydraulic scheme
Flows, pipe runs, buffer volume and manifolds drawn before any work.
Emitter plan
Underfloor, fan coils or radiators — matched to each room's real duty.
Placement & acoustics
Outdoor unit position planned for noise, distance and service access.
Future-proofing
Solar, batteries and pool heating provisioned from day one.
The price
A design fee that disappears.
The €490 fee is credited in full against a VELTORRA installation — so the design costs nothing extra when you proceed. If you don't, the report is still yours.
- On-site survey and measurements
- Room-by-room heat-load calculation
- Equipment and storage sizing
- Hydraulic and emitter scheme
- Written report you keep either way
The VELTORRA standard
Documented like every VELTORRA project.
Concealed work is photographed before it disappears behind walls, floors and ceilings.
Circuits, pressures and performance verified by measurement — not by assumption.
A documented workmanship guarantee alongside the manufacturer's warranty.
A single named person answers for your project — by message, if you prefer.

Questions, answered
Asked before hiring us.
Why pay for design when installers quote for free?
A free quote sizes from a catalogue; a design calculates from your home. The €490 fee is credited in full if we install — so the design costs nothing extra when you proceed.
What exactly do I receive?
A written report: heat-load figures per room, recommended equipment and storage, hydraulic scheme and emitter plan. It is yours to keep, whoever installs.
Do you design for renovations in progress?
Yes — that is the ideal moment: floor build-ups, pipe routes and the technical room are planned before finishes close.
Can you review a quote I already have?
Yes. We check the sizing and hydraulics against your home's numbers and tell you in writing what holds up and what doesn't.
How accurate is the calculation?
We use fabric-based, room-by-room methodology with Valencia climate data — the standard serious installers work to, documented so you can verify every figure.
Start with the numbers, not the invoice.
