NeoStat or NeoAir? Choosing the Best Heatmiser Thermostat for Water Underfloor Heating in 2025

Why Smart Thermostat Choice Matters for Water Underfloor Heating

Heating technology in UK homes has rapidly evolved, offering more control and comfort than ever before. Nowhere is this more apparent than in water-based underfloor heating systems, where smart thermostats allow precise room-by-room control, efficient scheduling, and seamless integration with daily routines.

The Neo range by Heatmiser stands out thanks to its robust features, ultra-modern design, and adaptability for new builds, renovations, or retrofits. Product reliability and up-to-date technology matter just as much as energy savings. For 2025, the spotlight falls on two favourites: the wired NeoStat V3 and its wireless counterpart, the NeoAir V3, both available through ThermRite.

Choosing between wired and wireless isn't always a question of what's technologically superior. It's about what fits your home's needs, building structure, and personal preferences. With water underfloor heating, the thermostat you select influences efficiency, comfort, and ongoing convenience.

Heatmiser NeoStat V3 vs NeoAir V3: Key Features and Differences

NeoStat V3: The Wired Flagship

NeoStat V3 connects directly to your underfloor heating system's manifold, ensuring a rock-solid connection and reliable temperature delivery. Wired thermostats appeal to those prioritising a traditional, cable-based setup.

• Core features:
• Wired operation for stable performance and no reliance on batteries
• 7-day programmable scheduling for room-specific comfort
• Floor sensor compatibility, ideal for bathrooms or zones where floor temperature regulation is essential
• Sleek, minimalistic design that fits modern interior aesthetics
• Seamless integration with the Heatmiser NeoHub for app-based and remote control

Owners of NeoStat V3 often highlight the peace of mind gained from dependable, direct wiring. Especially important in permanent installations or where future battery changes could be disruptive.

NeoAir V3: The Wireless Choice

NeoAir V3 steps away from cables entirely, offering freedom for homes where running new wiring isn't feasible. Whether avoiding invasive installation work in period properties or ensuring flexibility for future renovations, NeoAir V3 adapts with minimal fuss.

• Core features:
• Totally wire-free, battery-powered operation (with low-battery notifications)
• Full compatibility with Heatmiser's RF Switch and UH8-RF wireless receivers
• Advanced 7-day schedule programming and a holiday function
• Portable, making it easy to relocate as needs evolve
• Supports floor sensors for water underfloor heating control outside of bathrooms

Homeowners often select the NeoAir V3 where access is restricted or where maintaining an unspoiled décor is a top priority. In busy households, the flexibility to relocate the device adds tangible value.

How Heatmiser Transforms Zoning, Energy Efficiency, and Comfort

One standout benefit of the entire Heatmiser Neo range is zoning. The ability to set different temperatures for specific rooms, instead of unnecessarily heating areas that aren't in use. The NeoStat V3 and NeoAir V3 both empower homeowners to divide living spaces into independent zones, fine-tuning comfort while helping to shrink utility costs.

Zoning is more than just a technical upgrade. In a family home, it means warm bedrooms on chilly mornings while keeping unused guest spaces cooler. For open-plan living, precise control means no more hotspots around the kitchen and cold corners in the lounge. Users who embrace advanced zoning strategies through Heatmiser notice not just reduced running costs, but better flexibility to match their actual lifestyles.

Smart scheduling capabilities extend the energy-saving benefits, automatically lowering setpoints when rooms aren't occupied. Many users report noticeable drops in energy use after switching from traditional thermostats. Or even from basic programmable devices. Thanks to Heatmiser's advanced algorithms and learning functionality.

Personal comfort reaches a new level when paired with the NeoHub. With the Neo app, schedules can be updated remotely and rooms adjusted to meet the day's needs. Whether returning from holiday or staying late at work, you remain in the driver's seat.

Seamless Smart Home Integration. Alexa, Google Home, and Beyond

Smart home compatibility is a hallmark of the Neo series. Whether using NeoStat V3 or NeoAir V3, adding a NeoHub to the mix unlocks full integration with leading voice assistants. Owners can:
- Adjust heating via simple voice commands through Alexa or Google Home
- Incorporate heating control into broader routines (for example, setting all heating to eco mode with a single smart device action)
- Use IFTTT for custom automation across multiple platforms

This system flexibility means your underfloor heating responds fluidly to the pace of family life. Stop searching for the thermostat on frosty mornings. Simply say the word and watch your comfort level rise!

Whether you're deepening your smart home ecosystem or just dipping your toe in for the first time, the Neo range fits easily into natural routines, helping users enjoy both energy savings and ease of use.

Wiring and Compatibility: Getting the Details Right

Reliable performance hinges on correct wiring and system compatibility, especially when working with advanced heating solutions. The NeoStat V3 connects directly to the underfloor heating manifold and is best paired with UH8 wiring centres for multi-zone water underfloor heating systems. This combination offers professional-grade reliability, making it a favourite for new installations and complete system upgrades alike.

For homes needing a non-intrusive solution, the NeoAir V3 pairs perfectly with the UH8-RF wiring centre or an RF Switch module. Both available from ThermRite. By avoiding new wiring runs, these wireless controls allow quick retrofitting in properties where structural changes would otherwise be difficult or undesirable.

Compatibility is never an afterthought. Both NeoStat V3 and NeoAir V3 work seamlessly with Heatmiser's broader equipment range, ensuring a straightforward installation process. Adding a NeoHub enhances every feature, enabling app management, smart home links, and software updates. All supporting your heating system's performance in the years ahead.
