Smart Heating
Smart Underfloor Heating Control
Room-by-room automation built specifically for underfloor heating - turning a naturally slow system into one that's predictive, efficient, and effortless to live with.
Why Underfloor Heating Deserves Smart Control
Underfloor heating is arguably the smart home upgrade with the biggest return on intelligent automation. Unlike a radiator, which responds to a room's temperature within minutes, underfloor heating automation deals with a system that takes hours to heat up and hours to cool down. Get the scheduling wrong and you either waste huge amounts of energy heating a screed floor that never gets used, or you're sitting in a cold room waiting for warmth that's still an hour away.
Smart underfloor heating solves this by predicting demand rather than simply reacting to it. Using room sensors, occupancy patterns, and weather compensation, a properly configured underfloor heating control system brings each zone up to temperature exactly when it's needed - not too early, not too late - which is precisely why we recommend it as standard on almost every UFH project we design.
The comfort difference is noticeable too. Because underfloor heating warms a room evenly from the ground up rather than from a single radiator, it already feels different to live with - smart zoning simply makes sure that comfort extends to every room, at the right time, without the guesswork that a single whole-house thermostat forces on you.
How Smart UFH Control Works
At the heart of every automated system is the Loxone Miniserver, which coordinates underfloor heating actuators, manifold controllers, and both floor and room temperature sensors as one intelligent whole rather than a set of disconnected devices.
Where a standalone room thermostat can only react to what's already happened - the room has cooled, so switch the heating on - the Miniserver works predictively. It knows the thermal characteristics of each zone from ongoing monitoring, factors in outside temperature where weather compensation is enabled, and starts warming a room well before it's needed, rather than waiting for it to feel cold. For KNX installations, the same principle applies using bus-connected actuators and a central logic controller, giving equivalent control on projects where KNX is the preferred platform.
Manifold Actuators
Electric actuators fitted to each manifold port open and close individual UFH loops, giving true zone-by-zone control rather than one blanket temperature for the whole floor.
Room & Floor Sensors
Room temperature sensors measure the air you actually feel, while optional floor sensors monitor the slab itself - together giving the Miniserver an accurate picture of real conditions.
Centralised Coordination
The Loxone Miniserver (or KNX equivalent on suitable projects) manages heating demand across every zone at once, avoiding the inefficient short-cycling that standalone thermostats can cause.
Predictive Scheduling
Because UFH is slow to respond, the system learns how long each zone takes to heat and starts warming rooms in advance, so they're at temperature exactly when needed.
Water vs Electric Underfloor Heating
Smart control applies differently depending on which type of UFH your home has, and it's worth understanding the distinction before specifying a system.
Water Underfloor Heating
Water underfloor heating circulates warm water through pipework embedded in the floor, fed from a boiler or heat pump via a manifold. Smart control here means fitting actuators to each manifold port, allowing genuine zone-by-zone regulation of flow. This is the most common setup in new builds and larger renovations, and integrates particularly well with heat pumps, where consistent, low-temperature heat delivery is most efficient.
Electric Underfloor Heating
Electric underfloor heating uses heating mats or cables and is more common in smaller areas such as bathrooms or kitchens, or as a supplementary heat source. Smart control is achieved through dedicated relay or dimmer modules connected to the Miniserver, allowing the same scheduling, app control, and holiday modes as a wet system - though running costs and response times differ, so it's worth discussing which is right for your project at survey stage.
Many of our larger projects actually use both - water underfloor heating throughout the main living areas, fed from a heat pump or boiler, with electric UFH reserved for bathrooms where a quick, targeted burst of warmth underfoot is more useful than the slower response of a wet system. The Loxone Miniserver handles both types side by side without issue, so mixing them doesn't mean managing two separate control systems.
Smart UFH Features
Once a UFH system is under smart control, a wide range of features become available that simply aren't possible with a manifold left on manual or controlled by a single basic thermostat:
- Room-by-room temperature control across every UFH zone, controlled independently
- Underfloor heating scheduling by time of day, day of week, and detected occupancy
- UFH app control from anywhere via the Loxone app, plus optional voice control
- Frost protection to prevent cold-related issues in unoccupied rooms or during winter breaks
- Holiday modes that reduce heating demand while you're away, then bring the house back up to temperature before you return
- Full integration with heat pumps and boilers, plus energy monitoring so you can see exactly where heat is going
Yes - Loxone-based underfloor heating pairs directly with LoxVoice, letting you adjust zones with Alexa or Google Assistant using natural commands like "turn up the bathroom floor". No extra hardware, set up in minutes.
UFH in Our Projects
Underfloor heating automation features across many of our completed installations, including our self-build project at Graven Hill, a full underfloor heating installation as part of a whole-home retrofit in Bishop's Stortford, and mixed water/electric UFH zoning on projects in Ilketshall and Grantham. Each project demonstrates a different UFH project scenario - new build, renovation, and multi-zone retrofit - giving us hands-on experience of the specific challenges each brings.

If you're planning underfloor heating as part of a new build or considering retrofitting smart control to an existing wet or electric UFH system, our team can talk you through what's achievable for your specific property.
