Free delivery on eligible orders of £20 or more. Review: Low cost alternative to 'proper' smart valves - Easy to fit and work well. Instructions are fine if you follow carefully. These are programmable (time and temperature) rather than smart. I'm using them alongside connected/smart thermostats for some of the radiators, especially where I had two smart valves on different radiators in the same room which were fighting each other. Review: Avoid at all costs, better options out there. - These are terrible. They are my fourth variant of smart TRVs so I'm fairly accustomed how to program them. These are a different beast and not at all user friendly. Also almost impossible to calibrate. I set one room to 30 and the radiator remains freezing cold, another to 15 and it's constantly on. Absolute disaster. Hard to install, don't work, avoid. ## Features - Precision Temperature Control: The smart radiator valve allows you to fine tune each room or zone with remarkable accuracy. Utilise separate programming for each day/week and switch up to 6 times per day. - Reduce Energy Consumption: energy efficient radiator valves help save on heating bills by adjusting output to the rooms and times you need. Easily program the smart trv with exact temperatures from 5 up to + 30 degrees C. - Easy Installation: No DIY expert or tools required! The smart thermostat fits most standard radiator valves and simply screws onto existing systems. - Universal: Compatible with most heating systems (including Honeywell Home, Danfoss, MNG and Heimeier), making it a versatile choice. Whether you have a traditional radiator system or a more modern setup, you can enjoy precise temperature control. - Simple to Use: No app or wifi required. Always visible controls on a large LCD display which orientates to the left or right to suit the installation. The Rondostat and button control allow for precise manual temperature changes. - Convenient Features: Enjoy antifreeze and frost protection, open window detection, and economy mode to suit all of your heating needs. - Modern Design: Our stylish, low profile, smart thermostat valve combines a sleek, modern shape with accurate controls to fit perfectly into any interior or décor. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0CGK3JQNZ | | Batteries Required? | Yes | | Batteries included? | Yes | | Battery Cell Type | Alkaline | | Best Sellers Rank | 38,092 in DIY & Tools ( See Top 100 in DIY & Tools ) 201 in Home Programmable Thermostats | | Colour | White | | Customer Reviews | 3.4 3.4 out of 5 stars (433) | | Date First Available | 25 Aug. 2023 | | Delivery information | We cannot deliver certain products outside mainland UK ( Details ).

Instructions are fine if you follow carefully. These are programmable (time and temperature) rather than smart. I'm using them alongside connected/smart thermostats for some of the radiators, especially where I had two smart valves on different radiators in the same room which were fighting each other. ### ⭐ Avoid at all costs, better options out there. *by M***L on 26 October 2025* These are terrible. They are my fourth variant of smart TRVs so I'm fairly accustomed how to program them. These are a different beast and not at all user friendly. Also almost impossible to calibrate. I set one room to 30 and the radiator remains freezing cold, another to 15 and it's constantly on. Absolute disaster. Hard to install, don't work, avoid. ### ⭐⭐⭐ Could have had 5 stars *by C***M on 25 November 2025* I purchased six of these TRVs (three packs of two on a Black Friday deal) for fitting to my central heating radiators so that I could see the actual room temperature that each was set to rather than the 0-5 option of my conventional valves. I didn't want or need a wireless remote connection or boiler remote control and these TRVs fit the bill perfectly at a price point well below that of connected systems. Now installed, they are working well and maintain an accurate temperature in accordance with the digital display. So, why not 5 stars? The reason is the well justified criticism of the user guide/instructions as widely reported by others. There is some better documentation available online than that supplied in the box but even that lacks clarity. Such a shame that this very well made (and performing) device is difficult to recommend due to such appalling documentation. ## Frequently Bought Together - Honeywell Home Smart Radiator Thermostat Valve/HR 27 ECO ETRV/Programmable Thermostatic Radiator Valve/Digital Intelligent Central Heating Controller/White / 2-Pack - Honeywell Home Smart Radiator Thermostat Valve/HR 27 ECO ETRV/Programmable Thermostatic Radiator Valve/Digital Intelligent Central Heating Controller/White --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sk/products/570732355-hr27-2-pack](https://www.desertcart.sk/products/570732355-hr27-2-pack) --- *Product available on Desertcart Slovakia* *Store origin: SK* *Last updated: 2026-05-12*
