Full weather compensation & building comfort, built in from day one
Modern condensing boilers only hit their efficiency numbers when flow temperatures track outside conditions. We commission every installation with full weather compensation, optimum start/stop and zone-by-zone comfort control — so occupants are comfortable, gas bills drop, and the boilers run in true condensing mode for the majority of the year.
Outside-air weather compensation
External sensor + heating curve drives flow temperature from 40–80°C as outside temp changes. Cuts gas consumption by 10–18% versus fixed 80°C flow.
Optimum start / stop
BMS learns building thermal response and fires plant only as late as possible to hit setpoint at occupancy — and shuts down early without losing comfort.
Zone & room comfort control
Per-zone time schedules, room sensors, frost protection and DHW priority. Boost overrides for meeting rooms, classrooms and treatment areas.
Boiler sequencing & rotation
Lead/lag rotation across cascade boilers equalises run-hours, maximises modulation and keeps return temps below 55°C for true condensing operation.
Compliant comfort delivery
Designed to CIBSE TM52/TM59 comfort criteria and Part L energy targets. Documented strategy, point lists and seasonal commissioning included.
Measurable savings & reporting
BMS trends gas use, flow/return temps, run-hours and alarms. Monthly reports show condensing %, efficiency and where we can tune further.
