Why is Heatmiser the best control system for underfloor heating?

Heatmiser was built specifically for the UK heating market, and the NeoStat thermostat includes a dedicated floor sensor input — which is essential for wet UFH. The floor sensor prevents the floor temperature exceeding a set limit, protecting temperature-sensitive surfaces like engineered timber and natural stone. Tado and other mainstream smart thermostats don't offer this functionality without additional hardware.

What is the floor sensor input on the Heatmiser NeoStat and why does it matter?

The NeoStat has a dedicated input for a floor temperature sensor probe, which sits beneath the floor finish and continuously measures the actual floor surface temperature. The thermostat operates in two modes: air sensing (maintains the room air temperature) or floor sensing (limits the floor temperature to a maximum set-point). For engineered timber, this maximum is typically 27°C. Without this protection, the floor surface can overheat and cause warping or cracking.

Can Heatmiser control mixed wet UFH and radiator zones on the same system?

Yes — the NeoHub 2 is designed exactly for this. You can have NeoStat thermostats controlling UFH zone valves on the manifold alongside conventional radiator zones, all managed from the same NeoHub and app. This is one of the key reasons we specify Heatmiser for large London properties that often have a mix of UFH on lower floors and radiators upstairs.

How many UFH zones can Heatmiser control?

The NeoHub 2 supports up to 32 thermostats on a single hub, so in principle you can have up to 32 independent UFH zones. In practice, most London homes have between 4 and 14 zones. Each thermostat connects to a zone valve actuator on the UFH manifold and controls whether that zone calls for heat.

Can Heatmiser work with my existing UFH manifold?

In most cases, yes. Standard UFH zone valve actuators are compatible with Heatmiser thermostat wiring. During a survey, our engineers will confirm compatibility with your existing manifold and specify whether any actuator replacements are required. Most modern manifolds (Uponor, Emmeti, Rehau, OMNI) are fully compatible.

What's the difference between using Heatmiser for UFH versus a standalone UFH controller?

Standalone UFH controllers give you zone control but nothing else — they're essentially a simple timer and valve controller. Heatmiser Neo gives you individual room scheduling, remote access via app, integration with your boiler via OpenTherm, voice control, and the ability to manage the UFH alongside any conventional radiator zones in the same property — all from a single app.

How much does Heatmiser UFH control installation cost in London?

A single UFH zone with a NeoStat and floor sensor starts from £450–£600. A typical 4–6 zone UFH manifold with NeoHub and full app setup is £1,200–£2,200. Larger properties with 8–14 UFH zones range from £2,000–£3,800. All prices include the floor sensor probe, wiring, commissioning and app configuration.

Can you upgrade my existing UFH controller to Heatmiser?

In most cases, yes. If your existing UFH manifold has standard 230V zone valve actuators, we can replace the old wiring centre with a Heatmiser NeoHub and NeoStat thermostats using much of the existing wiring. We carry out a compatibility survey first to confirm the manifold and actuator type before quoting.

Heatmiser for UFH — London

Heatmiser for Underfloor Heating in London

Heatmiser is our preferred smart control system for wet underfloor heating across London's prime properties. The NeoStat thermostat's floor sensor input, per-zone scheduling and OpenTherm modulation make it the gold standard for UFH control — particularly where expensive floor finishes require active temperature protection.

Why Heatmiser for UFH

Built for underfloor heating — not just adapted for it.

Most smart thermostats were designed for conventional on/off radiator control and adapted for UFH. Heatmiser was built from the ground up for the UK market, with UFH as a primary use case — and the technical difference shows.

Floor Sensor Protection

The NeoStat's dedicated floor sensor input protects engineered timber, stone and tile from overheating — critical for expensive floor finishes.

Multi-zone on one app

Control every UFH zone and any radiator zones in the same property from a single NeoHub and one app — including mixed systems.

OpenTherm modulation

For compatible boilers, Heatmiser uses OpenTherm to modulate rather than on/off — far more efficient for low-temperature UFH circuits.

Independent scheduling

Every zone has its own independent schedule, set-point and boost — not a single programme for the whole house.

Why floor sensor protection matters in London's high-spec interiors.

Across Mayfair, Marylebone, Hampstead and Knightsbridge, we regularly work in homes with engineered oak, Versailles parquet, heated marble and porcelain tiles. Every one of these floor finishes has a maximum recommended operating temperature — typically 27°C for timber and 29°C for tile and stone.

Without a floor sensor, the UFH system cannot measure the floor surface temperature — it can only measure the air temperature. On a cold morning with the system calling hard, the floor temperature can significantly exceed these limits before the air temperature reaches set-point, causing damage to the floor finish that is expensive and sometimes impossible to remediate.

The Heatmiser NeoStat's floor sensor input solves this directly. We install a temperature probe beneath the floor finish, and the thermostat monitors the floor surface continuously — overriding the heating call if the floor temperature approaches the limit, regardless of what the air temperature is doing.

How we integrate Heatmiser with your UFH manifold.

1
Survey & zone layout
We assess the existing manifold, confirm actuator compatibility, and design the thermostat layout.
2
Actuator installation
Zone valve actuators are fitted to each manifold port, wired back to the NeoStat thermostats.
3
Floor sensor installation
Where required (timber floors particularly), floor temperature probes are installed via a conduit in the screed.
4
NeoHub commissioning
All zones are commissioned individually, tested for correct valve operation, and configured in the app.
5
Boiler integration
The NeoHub is connected to the boiler — via OpenTherm if compatible — and the heat demand logic is tested across all zones.
