Your plant room is probably
wasting more gas than you think
Most heating plant rooms accumulate inefficiencies over years - oversized pumps, excessive flow temperatures, uninsulated pipes, faulty controls. A professional energy audit identifies exactly where gas is being wasted and what to fix first for the biggest savings.
Find the gas savings hiding in your plant room
Gas prices have risen over 60% since 2021. Every unit of gas wasted in an inefficient plant room hits your bottom line harder than ever. A professional energy audit typically identifies 15-30% reduction opportunities - savings that pay for themselves within months.
Comprehensive Plant Room Survey
Our engineers assess your entire heating plant - boilers, HIUs, heat exchangers, pumps, pipework insulation, and controls. We identify inefficiencies that are silently costing you thousands in wasted gas every year.
Heat Loss Identification
Thermal imaging and flow/return temperature analysis pinpoint where heat is being lost. Uninsulated pipes, faulty valves, and oversized pumps are identified with clear remediation recommendations.
Gas Reduction Roadmap
Every survey delivers a prioritised action plan with projected gas savings for each measure. You see exactly what to fix first for the biggest return - no guesswork, just data-driven recommendations.
Implementation Support
We don't just identify problems - we help fix them. From specifying replacement equipment to managing installation, our team ensures energy-saving measures are implemented correctly.
Savings Verification
After implementation, HeatFlow tracks your actual gas consumption against the pre-survey baseline. You'll see whether projected savings are being achieved - and get alerts if they're not.

Common findings that save thousands
Flow temperatures set too high
We regularly find systems running at 80°C+ when 65-70°C would deliver the same comfort. Reducing flow temperature by 10°C can cut gas consumption by 8-12% with zero impact on residents.
Pumps running at maximum speed 24/7
Constant-speed pumps waste significant energy. Variable speed drives and weather compensation can reduce pump energy by 50% and gas consumption by 5-10% through better heat distribution.
Uninsulated pipework losing heat to risers
Heat lost in corridors and risers is heat you've paid for but nobody benefits from. Proper insulation of distribution pipework typically recovers 3-7% of total gas consumption.
Frequently Asked Questions
What does a plant room energy audit involve?
A comprehensive assessment of your heating plant including boiler efficiency testing, flow/return temperature analysis, thermal imaging of pipework, pump energy consumption, controls review, and HIU performance checks. You receive a detailed report with prioritised recommendations and projected savings.
How much can a plant room survey save on gas bills?
Typical findings identify 15-30% gas reduction opportunities. Common quick wins include optimising flow temperatures (often set too high), fixing stuck valves, insulating exposed pipework, and correcting oversized pump settings. Some sites have achieved 40%+ savings from addressing accumulated inefficiencies.
How long does a plant room survey take?
Most surveys are completed in a single day. Larger or multi-plant-room sites may require 2-3 days. We schedule surveys to minimise disruption to residents and building operations.
Do you only survey heat networks?
While our primary expertise is heat networks and communal heating systems, our plant room surveys cover any gas-fired heating installation. This includes commercial boiler systems, industrial heating, and mixed-fuel installations.
What happens after the survey?
You receive a detailed report within 5 working days, including findings, prioritised recommendations, projected savings, and implementation costs. If you proceed with recommendations, HeatFlow tracks your actual savings against the projections to verify ROI.
Can survey findings support a grant application?
Yes. Survey reports include the technical detail and projected savings data required for most energy efficiency grant applications, including the Public Sector Decarbonisation Scheme and local authority funding programmes.
