Know what a home needsbefore you spend.Keep knowing after.
You answer for millions of homes, and most of them are not connected to you yet.
HeatAssure™, from Aeterno, is the platform that keeps one governed record of every home you answer for, connected or not, and checks what was delivered against what was promised as evidence arrives.
What assurance wins you.
These are the three arguments that open an OEM account.
The tenders that now demand proof
Procurement is moving from specification to measured outcome. A bid whose numbers come from an independent record answers the question the tender is really asking.
Your brand, defended home by home
When a heat pump disappoints, the story names the manufacturer. Verification names the true cause while it can still be fixed.
A base that connects itself
Every verified home has a reason for its data to keep flowing. The connected share of your base grows with every programme.
Every home you answer for, sorted: ready now, needs evidence, not yet.
This is the picture a briefing starts from: your whole base, one list, three states.
The right system, sized right, with numbers that hold up when someone pushes back.
The decision is close. One or two facts would settle it, so surveys and visits go to the homes where they pay.
The honest state of part of any base, and a state that changes as the record fills in. Not a dead end.
Products that close the gap.
One line of products that closes the gap between the number a home was sold on and the number it delivers.
We call this HeatAssure.
Design assurance
Every home you answer for, scored from day one.
Nothing is installed in the home, and no home waits to be connected before it counts.
Bridge assurance
A short evidence capture qualifies homes before they are connected.
It settles whether a home is ready before anyone spends on it.
Operating assurance
Connected homes are checked against their own record.
Built to catch bad telemetry and explain it before it misleads anyone.
What's included
- Home assessmentHomes assessed with every figure carrying its source and confidence.
- Branded homeowner and installer documentsYour brand on everything a homeowner or installer is handed, carrying an independently verified result.
- Readiness captureThe capture journey that moves a home from needs evidence to ready now.
- Telemetry assuranceAnomalies caught and explained before your systems act on them.
- Commissioning verificationEvery install checked against its promise, exceptions first.
- Decision evidence packsEvidence assembled for the decision and the audience in front of it.
- HEM transition accessYour products run against the incoming Home Energy Model standard, so product-range decisions come early.
The first piece of work is defined and bounded; what follows is an annual licence covering the platform and its continuing improvement.
Your quote and design tools stay. They just get answers they can trust.
Your installers and engineers keep working where they already work. The record feeds them.
Your quote tool
Keeps its workflow. It gets sizing and performance numbers that hold up when an installer or a customer challenges them.
Your design software
Keeps its place in the job. It gets a governed record of the actual home, with every assumption recorded with its source and confidence.
Your monitoring platform
Keeps collecting. It gets the design promise to read performance against, home by home.
The same holds for what your teams build in-house: it stays, and it gains context from a record built across the whole market's certified products. What cannot be built in-house is standing. Your own monitoring answers your own question; a tender, a warranty case or an installer conversation asks whose number it is. The record has no stake in the sale, the installation or the outcome it judges, and that is what lets your evidence carry outside your walls.
The integration surface
- The interfaceAn API and a data contract your tools call. No new screen for your teams to learn.
- Where the record livesIn our cloud, in a tenancy that is yours: your own isolated instance, shared with no one. Nothing for your teams to host or install.
- What flows each wayYour jobs and telemetry flow in. Checkable numbers flow back, each one traceable to where it came from.
- OEM assessment and quoting run on HeatAssure in production today.
References, deployment detail and evidence packs are shared in confidence as part of diligence. No customer holds equity, a board seat, or influence over the method.
Each OEM runs in its own tenancy, with contractual data boundaries: your data, and anything that could identify your homes, your products or your commercial position, stays inside your tenancy. The record itself keeps learning, across public certification data and, under each customer's contract licence, from the verifications it runs, in de-identified aggregate, and every deployment starts with everything it has already learned.
The working behind these claims: the commissioning quality proof and how every calculation is validated on Technology. All the claims we make, on About.
This starts in the product, not on a slide deck: HeatAssure is in production today, and your line is already in the record.
- Your line, in the record already
Your certified products are in the record today. We run your line through the national fleet before we ever meet. Nothing needed from you to start.
- A working session in HeatAssure
Your base and your questions, in the production platform, against decisions you actually face.
- A first piece of work
Small, defined and judged on its own result. The output is yours to keep.
What you keep
- Your base sorted: ready now, needs evidence or not yet.
- What closes each evidence gap, home by home.
- The numbers behind every call, and where each one came from.
Bring the base you answer for.
Name a product line and we will run it through the record at no cost: UK stock, under the UK methods, today. Then a briefing covers what 'ready now', 'needs evidence' and 'not yet' would mean across your homes.
