After several months in development, a new homeowner platform called HomeTherma has launched in beta, with the aim of solving a problem that will be familiar to many heat pump owners: important information about the home and heating system is often scattered across multiple apps, emails, spreadsheets, documents and pieces of paper.
HomeTherma has been designed as a long-term digital companion for the home, bringing together information about the property, heating system, performance, maintenance, documents, upgrades and wider home-energy technologies in one place.
The idea grew out of a simple frustration. Heat pumps can generate years of useful information, but much of that history is fragmented or easily lost. When equipment is replaced, apps change, manufacturers disappear or paperwork goes missing, the homeowner can be left without a coherent record of how the system was originally designed, how it performed or what changed over time.
HomeTherma is intended to preserve that history.
At its core, homeowners can create a structured record of their property and heating system, including current and previous heating systems, controls, emitters, hot-water equipment and other useful design information.
Performance can then be recorded over individual months, heating seasons, years or longer historic periods, allowing users to preserve electricity consumption, heat delivered, temperatures and calculated efficiency alongside the exact period those figures relate to.
The platform also includes a Timeline for recording important changes to the system, maintenance records and reminders, document storage, Annual Reviews and a growing Insights engine designed to help homeowners understand the information they have entered.
Importantly, HomeTherma is not intended to diagnose faults or replace professional advice.
Instead, its purpose is to give homeowners better context around their own system, identify useful gaps in the information available and help them ask better questions when speaking to installers, engineers or manufacturers.
HomeTherma is also being developed around the property rather than the heat pump alone.
That means solar PV, batteries, EVs, chargers, tariffs and other home-energy technologies can eventually form part of the same long-term record, rather than existing as completely separate systems.
The project is currently in beta, and that is being made clear to early users.
There will still be bugs, rough edges and features that evolve significantly as more homeowners begin using the platform. The beta phase is deliberately being used to shape the product around what homeowners actually find useful rather than simply adding features for the sake of complexity.
Early users are being encouraged to provide direct feedback, with suggestions for new features and improvements receiving priority while HomeTherma is still being actively shaped.
There are currently Free and Premium versions of the platform.
The Free version allows homeowners to begin building their property and heating-system record, preserve heating-system history and record basic performance information.
Premium adds deeper functionality including Documents, Insights, Benchmarks, Annual Reviews, Maintenance, Energy and tariff records, advanced performance context and system comparisons.
To mark the beta launch, HomeTherma is also offering an early-adopter discount.
For a limited period, new users can receive 75% off HomeTherma Premium for life using the code:
The normal Premium price is £39.99 per year. Users joining with the EARLYTHERMA offer will retain the discounted rate for as long as their subscription remains active.
The intention is to reward the homeowners who are prepared to use the platform while it is still developing and, importantly, help influence what HomeTherma becomes.
HomeTherma is available now here.
For Renewable Heating Hub, this also represents an interesting next step.
Over the past several years, the forums have accumulated an enormous amount of collective homeowner experience around heat pumps: what works, what fails, how systems evolve and what information homeowners actually need.
HomeTherma takes a different approach to that same problem.
Rather than relying on scattered information and memory, it gives each homeowner a structured, persistent record of their own home-energy system that can become more useful with time.
The longer-term opportunity is even more interesting.
HomeTherma is being developed with future API integrations in mind, allowing data from monitoring platforms, heat pumps and other services to potentially flow into the platform automatically.
That could significantly reduce manual data entry and allow homeowners to receive much richer analysis and context from the information their systems are already producing.
For now, however, the priority is much simpler: get real homeowners using it, find the bugs, identify what is genuinely useful and keep improving it from there.
It seems to be biased very strongly towards air-water heat pumps and other water-based heating systems.
A fair point. A2As are easier in many ways from a hardware and pipework perspective and there is a pipeline release to support A2As. I’ll try and run that update this week to feature them more prominently.
