{"title":"Radiator Thermostats \u0026 TRVs | Manual and Smart Thermostatic Radiator Valves","description":"\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eA thermostatic radiator valve — or TRV — is one of the simplest and most cost-effective upgrades you can make to a wet central heating system. Fitted in place of a standard radiator valve, a TRV controls the flow of hot water into each individual radiator based on the temperature of the room around it. When the room reaches your desired temperature, the valve closes and stops the radiator heating further. When it cools down, it opens again. The result is that each room maintains a comfortable, consistent temperature without you having to manually adjust anything — and without wasting energy heating rooms that are already warm enough.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eManual TRVs vs Smart TRVs — What's the Difference?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eA \u003cstrong\u003emanual TRV\u003c\/strong\u003e has a numbered dial (typically 1–5) that you set once and leave. It's mechanical, battery-free, and entirely self-contained. These are a reliable, no-fuss option that suit most homeowners and are perfect for rooms that tend to stay at a predictable temperature. Our Reina Modal range covers this category, available in a wide range of finishes including chrome, anthracite, black, white, brushed, and bronze — in straight, angled, and corner configurations to suit any radiator installation.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eA \u003cstrong\u003esmart TRV\u003c\/strong\u003e replaces the manual head with a programmable, app-controlled or wireless unit that gives you precise scheduling, remote control via your phone, and often integration with your wider smart heating system. These are ideal if you want room-by-room control from anywhere, want to set heating schedules per room, or are building out a multi-zone smart heating setup.

Smart TRVs in our range that need this will include or offer a compatible adapter — check the individual product listing if you're unsure.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eIt's also worth knowing that a TRV controls only the individual radiator it's fitted to — it doesn't control your boiler or heating pump. For best results, TRVs work alongside a main room thermostat or smart thermostat that manages when the boiler fires. One room in your home (typically the hallway or living room) should always have a standard thermostat rather than a TRV, to ensure the boiler always has a reference point to work from.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eBrowse our full range of manual and smart thermostatic radiator valves below, or contact our team if you need help choosing the right TRV for your system.\u003c\/p\u003e","products":[{"product_id":"heatmiser-neoair-v3-wireless-smart-thermostat-black","title":"Heatmiser neoAir v3 Wireless Smart Thermostat - Black","description":"\u003c!-- Heatmiser neoAir v3 Wireless Smart Thermostat – Black --\u003e\n\u003cp\u003eThe Heatmiser neoAir v3 Wireless Smart Thermostat in Black offers full-featured, battery operated wireless control for \u003cstrong\u003eelectric \u003c\/strong\u003e\u003cstrong\u003eradiators, panel\/convector heaters via RF Switch 16A\u003c\/strong\u003e, \u003cstrong\u003ewet central heating\u003c\/strong\u003e (boiler systems with compatible RF receivers), and \u003cstrong\u003ehot water\u003c\/strong\u003e.

Rather than measuring temperature at the radiator itself, the ETRV works in a system with the ENGO E25 room thermostat, which measures true air temperature in the room from its wall-mounted position. The E25 thermostat sends commands to the ETRV heads to modulate the valve opening, achieving the setpoint temperature with a precision that a traditional manual TRV cannot match.\u003c\/p\u003e\n\u003cdiv class=\"engo-callout-blue\"\u003e\n\u003cstrong\u003e⚠️ E25 Thermostat Required\u003c\/strong\u003e\u003cbr\u003eThe ETRV-M30+RA does NOT operate as a standalone device. It must be paired with an ENGO E25 room thermostat (sold separately) to function. One E25 can control up to 6 ETRV heads within the same room. The E25 may be wall-mounted (230V) or battery-powered, and can be used standalone (offline) or connected to the EGATE-PRO gateway for full app and voice control.\u003c\/div\u003e\n\u003cp\u003eThe head ships with both an M30×1.5 direct-fit adaptor and a Danfoss RA adaptor, making it suitable for the two most common UK TRV valve configurations without any additional accessories. Installation is straightforward: remove the old manual TRV head, screw on the ETRV, insert batteries, and follow the E25 pairing procedure. The ETRV then automatically calibrates to the valve insert pin height.\u003c\/p\u003e\n\u003cdiv class=\"engo-callout\"\u003e\n\u003cstrong\u003e🪟 Open Window Detection — How It Works\u003c\/strong\u003e\u003cbr\u003eThe ETRV head's thermistor continuously monitors the local temperature at the radiator.

It mounts directly onto most standard radiator valves — replacing the existing TRV head without tools or wiring — and communicates wirelessly via \u003cstrong\u003eZigbee\u003c\/strong\u003e to the Wiser Heat Hub. From the Wiser Heat App (iOS and Android) or via voice commands (Amazon Alexa, Google Assistant), you can set independent daily and weekly schedules for every room, boost individual radiators for 30 minutes to 3 hours, and monitor energy use. The multiple onboard sensors enable \u003cstrong\u003eOpen Window Detection\u003c\/strong\u003e — automatically cutting the heat if a sudden temperature drop is detected — while \u003cstrong\u003eautomatic valve protection\u003c\/strong\u003e periodically exercises the valve mechanism to prevent limescale seizure. Certified to ErP Class A+1 and contributing a +5% ErP improvement rating, the thermostat supports Wiser's Eco Mode, Away Mode and Comfort Mode for intelligent, low-waste heating across the whole home. \u003cstrong\u003eA Wiser Heat Hub (sold separately) must already be installed\u003c\/strong\u003e to use this device.\u003c\/p\u003e\n  \u003c\/div\u003e\n\n  \u003cdiv class=\"wd-stat-bar\"\u003e\n    \u003cdiv class=\"wd-stat\"\u003e\n\u003cdiv class=\"num\"\u003e0–45°C\u003c\/div\u003e\n\u003cdiv class=\"lbl\"\u003eTemperature Range\u003c\/div\u003e\n\u003c\/div\u003e\n    \u003cdiv class=\"wd-stat\"\u003e\n\u003cdiv class=\"num\"\u003e16\u003c\/div\u003e\n\u003cdiv class=\"lbl\"\u003eRooms \/ Zones\u003c\/div\u003e\n\u003c\/div\u003e\n    \u003cdiv class=\"wd-stat\"\u003e\n\u003cdiv class=\"num\"\u003e32\u003c\/div\u003e\n\u003cdiv class=\"lbl\"\u003eMax Radiators\u003c\/div\u003e\n\u003c\/div\u003e\n    \u003cdiv class=\"wd-stat\"\u003e\n\u003cdiv class=\"num\"\u003e+5%\u003c\/div\u003e\n\u003cdiv class=\"lbl\"\u003eErP Rating\u003c\/div\u003e\n\u003c\/div\u003e\n    \u003cdiv class=\"wd-stat\"\u003e\n\u003cdiv class=\"num\"\u003e~18%\u003c\/div\u003e\n\u003cdiv class=\"lbl\"\u003eEnergy Saving (typical)\u003c\/div\u003e\n\u003c\/div\u003e\n    \u003cdiv class=\"wd-stat\"\u003e\n\u003cdiv class=\"num\"\u003e2 yr\u003c\/div\u003e\n\u003cdiv class=\"lbl\"\u003eGuarantee\u003c\/div\u003e\n\u003c\/div\u003e\n  \u003c\/div\u003e\n\n  \u003cdiv class=\"wd-award-banner\"\u003e\n    \u003cdiv class=\"star\"\u003e🏆\u003c\/div\u003e\n    \u003cdiv\u003e\n      \u003cstrong\u003eRed Dot Award — Product Design 2018\u003c\/strong\u003e\n      \u003cp\u003eRecognised internationally for outstanding design quality, the Wiser Radiator Thermostat won the prestigious Red Dot Award for its distinctive twist-top interface, compact form and clean aesthetic — inspired by the iconic Drayton TRV4 but reimagined as a modern smart device.\u003c\/p\u003e\n    \u003c\/div\u003e\n  \u003c\/div\u003e\n\n  \u003ch2\u003eKey Features\u003c\/h2\u003e\n  \u003cdiv class=\"wd-grid\"\u003e\n    \u003cdiv class=\"wd-card\"\u003e\n\u003cstrong\u003e🌡️ Multi-Sensor Precision Temperature Control — 0 to 45°C\u003c\/strong\u003eMultiple integrated temperature sensors provide highly accurate room temperature measurement, minimising the temperature swing typical of single-sensor TRVs. The thermostat controls water flow through the radiator to maintain the target temperature precisely. The full 0–45°C range covers everything from frost protection (typically set at 5°C) through sleeping temperatures to maximum warmth for a cold bathroom.\u003c\/div\u003e\n    \u003cdiv class=\"wd-card\"\u003e\n\u003cstrong\u003e📱 App-Based Room Scheduling via Wiser Heat App\u003c\/strong\u003eEach radiator thermostat can be assigned to a named room within the Wiser app and given its own fully independent daily or weekly heating schedule. Set different temperatures for morning, daytime, evening and overnight in every room — so bedrooms can cool down while the living room stays warm, or a child's nursery maintains a constant temperature regardless of the rest of the house. The app works on your home Wi-Fi network without internet access; remote access from outside the home requires an internet connection.\u003c\/div\u003e\n    \u003cdiv class=\"wd-card\"\u003e\n\u003cstrong\u003e🔄 Twist-Top Boost Interface with Spring-Back\u003c\/strong\u003eThe distinctive twist-top lets anyone in the room boost the temperature without needing the app. Twist it up to increase the setpoint, twist it down to reduce it, or activate a timed boost. When released, the top springs back to its neutral position — providing tactile confirmation of the adjustment while keeping the design clean and unobtrusive. This physical boost function is particularly useful for guests or family members who don't use the app.\u003c\/div\u003e\n    \u003cdiv class=\"wd-card\"\u003e\n\u003cstrong\u003e🪟 Open Window Detection\u003c\/strong\u003eWhen a window is opened, the room temperature typically drops rapidly. The Wiser TRV's multiple sensors detect this sudden temperature fall and automatically shut the radiator valve to prevent heating a room with a window open — eliminating the common energy waste of running the boiler while cold outside air pours in. The heating resumes automatically once the temperature stabilises after the window is closed.\u003c\/div\u003e\n    \u003cdiv class=\"wd-card\"\u003e\n\u003cstrong\u003e🔒 Device Lock — Child \u0026amp; Tamper Protection\u003c\/strong\u003eActivate the Device Lock feature via the app to prevent the physical controls from being changed at the thermostat. Ideal for households with young children who might otherwise play with the twist-top, or for shared properties and offices where you want to prevent local overrides. Temperature setpoints and schedules can still be managed from the app.\u003c\/div\u003e\n    \u003cdiv class=\"wd-card\"\u003e\n\u003cstrong\u003e⚙️ Automatic Valve Protection — Anti-Limescale\u003c\/strong\u003eThe Wiser TRV periodically runs an automatic valve exercise cycle, moving the pin mechanism even when the valve has been in one position for a prolonged period. This prevents the common issue of limescale seizing the valve in an open or closed position — a leading cause of radiators that won't shut off or won't heat up — protecting both the thermostat and the valve body itself from long-term damage.\u003c\/div\u003e\n    \u003cdiv class=\"wd-card\"\u003e\n\u003cstrong\u003e🔵 Zigbee Wireless — Mesh Network via Wiser Heat Hub\u003c\/strong\u003eThe thermostat communicates via the Zigbee wireless protocol to the Wiser Heat Hub, which acts as the system coordinator. Zigbee devices form a self-healing mesh network — each device can relay signals from others, extending the network's range and resilience. No hub or bridge is required at each radiator; one Wiser Heat Hub supports the full system of up to 32 radiator thermostats in up to 16 rooms.\u003c\/div\u003e\n    \u003cdiv class=\"wd-card\"\u003e\n\u003cstrong\u003e🎙️ Voice Control — Alexa, Google Assistant \u0026amp; IFTTT\u003c\/strong\u003eWorks natively with Amazon Alexa and Google Assistant for voice commands such as \"Alexa, set the living room to 21 degrees\" or \"OK Google, boost the kitchen heating.\" IFTTT integration enables advanced automation, including geofencing — so Away Mode can activate automatically when your smartphone leaves the home area, without any manual intervention.\u003c\/div\u003e\n  \u003c\/div\u003e\n\n  \u003ch2\u003eSmart Heating Modes\u003c\/h2\u003e\n  \u003cdiv class=\"wd-mode-grid\"\u003e\n    \u003cdiv class=\"wd-mode-card eco\"\u003e\n      \u003cspan class=\"ico\"\u003e🌿\u003c\/span\u003e\n      \u003cstrong\u003eEco Mode\u003c\/strong\u003e\n      \u003cp\u003eReduces heating to a lower background temperature when rooms are unlikely to be occupied, reducing boiler running time and energy waste without letting the home get cold.\u003c\/p\u003e\n    \u003c\/div\u003e\n    \u003cdiv class=\"wd-mode-card away\"\u003e\n      \u003cspan class=\"ico\"\u003e✈️\u003c\/span\u003e\n      \u003cstrong\u003eAway Mode\u003c\/strong\u003e\n      \u003cp\u003eOverrides all schedules and drops setpoints to a low frost-protection temperature when you leave home.

The WV704R0A0902 is an add-on device — it only works as part of an existing Drayton Wiser smart heating system. You must already have a Wiser Heat Hub installed and commissioned. The Hub is included in all Drayton Wiser Kits (available in single-zone and multi-zone versions for combination and system boilers). If you're starting from scratch, you need a Wiser Kit first; if you already have a Wiser system, this thermostat can be added to it at any time.\u003c\/p\u003e\n  \u003c\/div\u003e\n  \u003cdiv class=\"wd-faq-item\"\u003e\n    \u003ch3\u003eHow many of these do I need?\u003c\/h3\u003e\n    \u003cp\u003eFor maximum energy saving and comfort, Drayton recommends one thermostat per radiator. However, most people prioritise the rooms they use most — fitting a thermostat in the living room, main bedroom, kitchen and bathroom first, then expanding over time. A single Wiser system supports up to 32 radiator thermostats across up to 16 rooms, so you can grow the system gradually and add more thermostats whenever you like.\u003c\/p\u003e\n  \u003c\/div\u003e\n  \u003cdiv class=\"wd-faq-item\"\u003e\n    \u003ch3\u003eCan I install this myself?\u003c\/h3\u003e\n    \u003cp\u003eYes — no tools or wiring are needed. Unscrew the existing TRV head anticlockwise from the valve body, then screw the Wiser head on using the supplied ring nut. Use the Danfoss RA adapter if your valve requires it. Then open the Wiser app to add the new device to your system. Drayton suggests the installation takes around 5 minutes per radiator. If you are unsure about your valve type, a qualified heating engineer can confirm compatibility.\u003c\/p\u003e\n  \u003c\/div\u003e\n  \u003cdiv class=\"wd-faq-item\"\u003e\n    \u003ch3\u003eWill it work with my boiler?\u003c\/h3\u003e\n    \u003cp\u003eThe Wiser system is compatible with all common UK boiler types, including combination boilers, system boilers and heat-only (regular) boilers. It is not compatible with gravity-fed central heating systems (found in some older properties where the header tank is in the loft), or with boilers that require their own manufacturer-specific controls to function. If you are unsure, check with your heating engineer. The Wiser Heat Hub installation guide also lists confirmed compatible boiler types.\u003c\/p\u003e\n  \u003c\/div\u003e\n  \u003cdiv class=\"wd-faq-item\"\u003e\n    \u003ch3\u003eCan I use voice control to set individual room temperatures?\u003c\/h3\u003e\n    \u003cp\u003eYes. Once connected to Amazon Alexa or Google Assistant via the Wiser skill\/action, you can control individual rooms by name — for example, \"Alexa, set the bedroom to 18 degrees\" or \"OK Google, boost the living room heating.\" The Wiser app also lets you group rooms so you can control multiple zones at once with a single voice command.\u003c\/p\u003e\n  \u003c\/div\u003e\n  \u003cdiv class=\"wd-faq-item\"\u003e\n    \u003ch3\u003eHow does Open Window Detection work?\u003c\/h3\u003e\n    \u003cp\u003eThe thermostat's multiple onboard sensors continuously monitor the room temperature. When a window or external door is opened, cold air causes a rapid fall in measured temperature. The Wiser TRV detects this sudden drop and automatically closes the valve to stop heating the room — preventing energy waste from heating a room with a window open. Once the temperature stabilises (indicating the window has been closed), normal heating resumes automatically. No user intervention is needed.\u003c\/p\u003e\n  \u003c\/div\u003e\n  \u003cdiv class=\"wd-faq-item\"\u003e\n    \u003ch3\u003eIs it compatible with Home Assistant or Zigbee2MQTT?\u003c\/h3\u003e\n    \u003cp\u003eThe WV704R0A0902 uses standard Zigbee and has community-verified support in Zigbee2MQTT (device model \"iTRV\", manufacturer \"Schneider Electric\"). It can be integrated into Home Assistant and similar platforms by pairing it directly with a Zigbee coordinator rather than the Wiser Hub. Note that operating it outside the Wiser ecosystem means the Wiser app features (Comfort Mode, Away Mode, etc.) are not available — you would configure the thermostat behaviour entirely within your chosen home automation platform.

current M30×1.5mm thermostatic heads, including smart TRVs such as the Drayton Wiser Radiator Thermostat.

Radiators without a Hive TRV continue to work as normal, controlled by your main thermostat and the physical dial on the valve. However, for the best energy savings, fitting TRVs in all rooms allows the system to actively prevent heating unoccupied spaces. One important note: it is good practice to leave at least one radiator on the system \u003cstrong\u003ewithout a TRV\u003c\/strong\u003e (or with its TRV fully open) as a bypass, to prevent the circulating pump working against closed valves if all rooms reach their target temperature simultaneously.\u003c\/div\u003e\n    \u003c\/details\u003e\n\n    \u003cdetails style=\"border-bottom:1px solid #c8e6e3;\"\u003e\n      \u003csummary style=\"padding:13px 16px;cursor:pointer;font-weight:600;background:#f0faf9;\"\u003eHow long do the batteries last, and what type do I need?\u003c\/summary\u003e\n      \u003cdiv style=\"padding:11px 16px;font-size:14px;\"\u003eThe Hive Smart TRV is powered by \u003cstrong\u003e2× AA batteries (supplied in the box)\u003c\/strong\u003e.

The app will notify you when the battery level is low, giving you time to replace them before the valve loses communication.
