START SIMPLE. GO DEEPER LATER.
Useful from the beginning. More valuable over time.
You do not need to understand your entire heating system before HomeTherma becomes useful.
Record the basics
Add your home, heating system and whatever information you already know. Leave anything blank when you are unsure.
Build the picture
Bring performance, maintenance, documents, controls and system history together around the property.
Understand change
Use cautious Insights, comparisons and Annual Reviews to see what changed and what may be worth exploring.
A PERMANENT HOME-ENERGY RECORD
Keep the facts, history and context together.
HomeTherma is built around the home, not a single appliance. It preserves current and historical systems so replacements, improvements and performance records stay connected to the correct era.
PERFORMANCE WITH CONTEXT
Keep the period exactly as you recorded it.
Use a month, heating season, year or longer historic period. HomeTherma keeps the dates, source and figures together rather than forcing unlike periods into a false comparison.
- Electricity used and heat delivered
- Calculated efficiency where dates match
- Optional flow, return, outdoor and indoor temperatures
- Notes explaining control changes, upgrades or unusual weather

HomeTherma treats this as one recorded heating season, not six invented monthly readings.
INTERPRETATION, NOT DIAGNOSIS
Understand what your records may be telling you.
HomeTherma can connect design information, emitters, controls, hydraulics, performance and changes over time to surface useful context.
It does not diagnose faults or replace a qualified professional. Missing information reduces confidence rather than producing fake certainty.

HomeTherma InsightBased on your records
Your later performance period used a lower average flow temperature.
Recorded efficiency was also higher, but these periods cover different dates. Weather, hot-water use and other changes may also have influenced the result.

A RECORD THAT SURVIVES REPLACEMENT
Your previous system should not vanish when the next one arrives.
HomeTherma keeps each heating-system era as a historical snapshot. Performance, documents, maintenance and Timeline events remain attached to the system they belonged to.
COMMUNITY INTELLIGENCE
Understand your home in the right context.
As HomeTherma grows, anonymised and aggregated data can support comparisons between genuinely similar homes and systems.

Comparisons are only shown where there is enough relevant data to make them meaningful. Users control whether their data contributes to anonymous benchmarking.
BUILT FOR HOMEOWNERS
Your information remains yours.
HomeTherma is designed to help homeowners preserve reliable information and make better-informed decisions. Your record can be downloaded from your account whenever you choose.
HomeTherma’s value comes from organising and interpreting your information—not from preventing you from taking it elsewhere. Paid access can add services, but it does not change who owns the underlying record.
Commercial partners cannot influence individual guidance, Insights or benchmarking. Partner-funded access may be offered, but the product remains independent.
HomeTherma does not diagnose faults, guarantee savings or replace professional advice.
