Which Honeywell T6 fits your home best: wired simplicity or wireless hot water control?

Display

Both products appear to use the same Honeywell T6 family touchscreen interface, so there is no clear winner on screen quality from the information provided. Expect a modern, easy-to-read display with app-based control and smart features like geofencing and voice assistant compatibility. Because the core UI is effectively shared, this category is a tie. Winner: Tie.

Performance

On pure smart-thermostat functionality, both are strong. Each supports app control and works with major ecosystems: Alexa, Apple HomeKit, Google Home, and IFTTT. Product A is specifically positioned as an 868 MHz wired thermostat and a CM907 replacement, which makes it especially suitable for straightforward heating control on compatible systems, including combi boilers. Product B adds wireless operation and dedicated hot water control, which increases flexibility for homes with separate heating and hot water zones. If you only need room heating control, Product A is simpler and more direct; if you want heating plus hot water scheduling, Product B has the broader feature set. Winner: Product B.

Build quality and design

Honeywell Home has a strong reputation in UK heating controls, and both products benefit from the same brand trust and similar user ratings. Product A’s wired design can feel cleaner in a retrofit if you are replacing an existing hardwired controller like a CM907, because it avoids a visible receiver/relay unit in the same way some wireless systems require. Product B’s wireless design is more installation-friendly in properties where running new cables would be disruptive, but it introduces an extra component and slightly more complexity. In design terms, Product A is the neater choice for fixed installations; Product B wins on flexibility. Winner: Product A.

Battery life

Neither listing provides explicit battery-life figures, so there is no hard data advantage here. In practice, wireless thermostats like Product B typically rely more on batteries in the room unit and may need occasional replacement or charging depending on the exact setup, while wired thermostats like Product A can often draw power through the heating circuit or have fewer battery concerns at the user-facing unit. Because the product data doesn’t specify exact runtime, this is best treated as a practical rather than quantified advantage. On balance, Product A is the lower-maintenance option. Winner: Product A.

Price and value for money

This is the clearest measurable difference. Product A costs £179.00, while Product B costs £148.56, making Product B cheaper by £30.44. Since both have the same 4.4/5 rating and almost identical review counts, Product B offers better value if you want the extra hot water control without paying more. In UK terms, that price gap is meaningful: if your goal is to trim heating costs and improve control, the cheaper model leaves more budget for insulation, TRVs, or other efficiency upgrades. Winner: Product B.

Game library/features

For a thermostat comparison, the equivalent of “game library” is feature set, and Product B wins here. It includes wireless smart thermostat control plus hot water control, which is a major advantage for homes with separate hot water cylinders or more complex scheduling needs. Product A still offers geofencing, app control, and voice assistant compatibility, but it is the more focused heating-only option. If you want the most complete feature package in one device, Product B is the stronger pick. Winner: Product B.

Overall user experience

Product A is likely the better experience for someone replacing an existing wired controller and wanting a clean, straightforward install. Its CM907 replacement positioning is a big clue: it is designed to slot into common UK heating setups with minimal fuss. Product B is better for households that want more control, especially if hot water scheduling matters, and its wireless format can make installation easier where wiring is awkward. For typical UK energy-conscious households, the best smart thermostat is the one you’ll actually use consistently: if your system supports it, Product B’s extra control can help reduce wasted heating and hot water use, especially during shoulder seasons when demand is lower and fine scheduling matters most. Overall summary: Product B is the better all-round buy because it is cheaper, equally well reviewed, and adds hot water control plus wireless flexibility. Product A is still the better specialist choice for a direct wired replacement and simpler heating-only setups.
