The Gap

Subsidised installations. Invisible defects. Expired warranties.

France subsidises hundreds of thousands of heat pump installations every year, and a substantial share underperform from day one. The defects sit in the equipment data. The first visible signal is the electricity bill — two or three winters later, after the installer's two-year warranty has expired.

Stage 01 — First heating season

The defect operates quietly

A mis-sized, mis-configured or mis-charged unit still heats the house. Consumption climbs, comfort erodes, and nothing is inspected. The evidence accumulates only in telemetry.

Stage 02 — Year two

The remedy window closes

The garantie biennale — the installer's two-year warranty — expires. With it goes the cheapest and most direct path to a correction.

Stage 03 — Year three

The bill is the first signal

The electricity bill finally tells the homeowner something is wrong. By then the installer is out of reach, and the cost has shifted to owners, insurers and public budgets.

Product

Verification, during the season that matters.

Tepidus is the independent verification layer between the installed heat pump and the institutions that carry its risk. The platform reads telemetry, compares it against a calibrated reference, and classifies deviations by cause — during the first heating season, while remedies are open.

How It Works

Three stages, one heating season.

Connect

Tepidus connects through manufacturer cloud APIs where they exist. Where they do not, an optional independent telemetry module closes the gap. The hybrid approach covers the full installed base.

Compare

A reference-model library calibrated to French housing stock and climate zones H1–H3 defines what each installation should deliver, hour by hour, across the full range of outdoor conditions.

Act

Deviations are classified by cause and routed to the institutions that need them — while the garantie biennale, the installer's two-year warranty, is still open.

Illustrative findings. Values shown are representative.

Five defect classes. One data stream.

The most common installation defects each leave a distinct signature in telemetry. Tepidus classifies the cause, not just the symptom.

Air-to-water installation. Numbered points mark where each defect class arises: ① unit sizing, ② hydraulic configuration, ③ pipe insulation, ④ refrigerant charge, ⑤ control settings.

Unit sizing: An over- or under-sized unit short-cycles or runs flat out. Both regimes leave a distinct run-time signature in the compressor data.
Hydraulic configuration: Wrong flow rates or buffer arrangements starve the emitters. Delivered heat sits below design output at every load point.
Pipe insulation: Heat lost between the outdoor unit and the dwelling shows up as a persistent, weather-correlated efficiency gap.
Refrigerant charge: An incorrect refrigerant charge degrades the compression cycle in a pattern that separates cleanly from the other four causes.
Control settings: A mis-set heating curve or operating mode wastes energy in mild weather — the most common defect, and the cheapest to correct.

Data Protection

Data protection, by design.

Tepidus operates a CNIL-aligned data-protection framework, and processing follows the GDPR from the first day of operation.

We apply data minimisation: the platform collects the telemetry the verification requires, and nothing else. All infrastructure runs in the European Union.

Who We Serve

Built for the institutions that carry the risk.

Tepidus is a B2B platform. Six institutional segments carry the financial risk on installation quality, and each receives the evidence it needs. Homeowners receive findings transparently, but they are not the paying customer.

7M installed — verified by no one.

Property Insurers

Defective installations create loss exposure that stays invisible until a claim arrives. Verification data prices installation quality into underwriting and claims handling.

Pain point — an insurer cannot distinguish a sound installation from a defective one at policy inception.

Public Authorities

Public bodies are accountable for subsidy outcomes, not just subsidy volumes. Per-installation verification shows whether public money produces the intended energy savings.

Pain point — today, outcome data stops at the invoice.

Retrofit Lenders

Energy-renovation loans are underwritten against projected savings. Verification confirms whether the projections hold, loan by loan and across the portfolio.

Pain point — a defective installation quietly erodes the borrower's repayment capacity.

Bailleurs Sociaux

Social housing operators run thousands of near-identical units. Portfolio-level monitoring works from a single reference model per building typology.

Pain point — tenants carry the cost of defects through their energy bills long before anyone inspects.

ESCOs

Performance contracts carry direct exposure on delivered efficiency. Continuous verification protects the contract economics from the first heating season.

Pain point — without independent data, every dispute over delivered performance becomes a negotiation.

Syndics de Copropriété

Collective installations serve many owners with divergent interests. Neutral evidence resolves disputes between residents, installers, and managers.

Pain point — when performance disappoints, the syndic stands between unhappy residents and a distant installer.

Manufacturers

Partners, not customers.

Equipment manufacturers participate as integration partners under data agreements. They are not paying customers. This separation preserves the independence of every verification Tepidus issues.

Market

France is Europe's largest residential heat pump market.

Around 7 million heat pumps operate in French homes at the start of 2026. The industry targets 8.8 million by 2030. Every new installation is a first heating season waiting to be verified.

Regulation

Twelve months that reset the market.

2025 — February 2026

MaPrimeRénov' programme disruptions

The subsidy programme stopped and restarted twice in 2025, and a third suspension ran into February 2026. Institutional buyers no longer assume subsidy continuity, and scrutiny of outcomes rises.

19 February 2026

Loi de Finances 2026 promulgated

The 2026 budget law confirms the framework for energy-renovation support and stabilises the planning horizon for institutional buyers.

February 2026

AFPAC Plan d'Action

The industry commits to a course toward 8.8 million installed heat pumps by 2030 and raises the bar on installation quality.

March 2026

CEPAC founded

AFPAC, Uniclima, CETIAT, EDF and Domofinance create a standards body that calls for per-installation conformity verification.

1 September 2026

Gas boilers leave MaPrimeRénov' support

Heat pumps become the default replacement path. Volumes rise, and so does the cost of undetected defects.

Company

Installation-quality data, as standard infrastructure.

Tepidus exists to make installation-quality data part of the standard infrastructure of the energy retrofit market. Verification should be as routine as the invoice.

Ten to twelve roles. Twenty-four months. France.

Tepidus incorporates in France. Research, engineering, and customer-facing operations are located in France, and the work aligns with France 2030 decarbonisation objectives.

Within three to five years, Tepidus aims to be the reference independent verifier of residential heat pump performance in France — and, beyond that, a recognised European platform for installation-quality data.
