For most homes, yes — but the real gain comes from the control protocol, not the app. A properly fitted OpenTherm thermostat lets the boiler modulate and spend more time in condensing mode, which is where the efficiency saving is. The phone app is a nice-to-have on top.
Heating controls — Edinburgh & the Lothians
Controls that actually make your boiler work properly.
Smart thermostats, OpenTherm pairing, weather compensation, and zoning — fitted so a modern condensing boiler runs the way it's designed to, not just switched on and off. Gas Safe registered, tidy install, fixed quote.

What We Fit
The controls that make a real difference.
Not every upgrade is worth the money. These are the ones that actually change how a heating system runs — fitted properly to your boiler, your house, and your routine.
OpenTherm smart thermostats
Properly modulating thermostats that talk to the boiler over OpenTherm — so the boiler runs at lower flow temperatures for longer and stops short-cycling. The efficiency gain sits here, not in the phone app.
Weather compensation
An outdoor sensor lets the boiler adjust flow temperature to the weather, rather than running flat out every time the thermostat calls for heat. Quieter, cheaper, and kinder to the heat exchanger.
Load compensation & modulation
Controls that vary boiler output based on how cold the room actually is, rather than switching on and off around a fixed setpoint. Most modern condensing boilers can do this — they just need the right control paired with them.
Zoning & multi-zone wiring
Separate upstairs and downstairs, or living and sleeping zones, so you're not heating empty rooms. Done properly at the wiring centre, not bodged on with individual radiator timers.
TRVs and smart TRVs
Proper thermostatic radiator valves fitted in the right places, or smart TRVs where a room genuinely benefits from individual scheduling — without turning a simple heating system into a battery-changing chore.
Replacing old programmers
Failing mechanical programmers, worn wiring centres, and stuck time clocks swapped out for clean modern controls that actually work with how a condensing boiler is meant to run.
Why It Matters
The gain is in the control, not the gadget.
Most boilers in Scottish homes are working far harder than they need to because the thermostat can only switch them on or off. The right controls let a modern boiler modulate — which is where the real efficiency, comfort, and quietness come from.
Efficiency
The boiler finally runs the way it's designed to
Most condensing boilers are fitted to systems where the controls only ever switch them on or off. With OpenTherm or weather compensation, the boiler modulates down, spends more time in condensing mode, and uses less gas over a winter — without changing the boiler itself.
Comfort
Temperatures hold steady, rooms feel even
A properly configured smart thermostat holds the target temperature more steadily than a basic mechanical stat. Combined with balanced radiators and decent TRVs, rooms stop feeling stuffy then cold within the same hour.
Control
Honest setup, not feature bloat
We set up the controls so they actually work for your routine, not a demo in a showroom. App, voice assistant, geofencing — only where it genuinely helps. The goal is a warmer house for less, not a dashboard.
How It Works
From visit to a properly set up system.
Upgrading controls should not be complicated. It's a short visit, a fixed quote, a tidy install, and a walk-through so you can actually use what you've paid for.
01
Quick home visit and system check
We look at the boiler, the existing wiring centre, and how the current controls are set up. Most upgrade issues are not the thermostat itself — they're wiring, boiler protocol, or radiator balancing.
02
Honest recommendation and fixed quote
We recommend the control set that actually fits the boiler and the house — not the one with the slickest box. You get a fixed written quote before anything gets ordered.
03
Clean install and correct wiring
Wired properly at the wiring centre, paired over OpenTherm or the boiler's native protocol, and tidy cable runs. No surface-mounted trunking where it isn't needed.
04
Commissioning and walk-through
Flow temperatures set to suit the house, schedules built around your routine, and a straightforward handover so you can actually use what you've paid for.
