  • Is it worth having TRVs installed? 2022-11-28
    Thermostatic radiator valves, also known as TRVs, are valves that regulate the temperature of the radiator based on the temperature of the room. It helps create a more responsive heating system, allowing you to maintain a desired temperature in each room individually.   If your central heating system is one boiler with one thermostat that determines the heating level for the whole house, TRVs would give you a separate thermostat on each radiator that controls the heat within that room. Obviously, a single thermostat will determine the heating based on the temperature in the room that it is located in yet the temperature will inevitably vary across different rooms based on size of room, size of radiator and position within the house relative to the boiler.
  • ecobay's Smart Radiator Valves are a beautiful privilege reserved only for Europe 2022-11-17
    Smart thermostats are cool. They save energy, lower bills, and they make your house look like the futuristic residence of a Star Trek character. The problem is, I live in an apartment in New York City that only has a radiator, so I can’t really get in on the connected home action.   Fortunately for me, ecobay, a company that specializes in modern, minimalist smart home tech, just announced at IFA its new Smart Radiator Valves, which adds smartphone control to individual radiators. The Smart Radiator Valve can control valves to start and stop heating the room as desired, allowing for room-by-room temperature control and scheduling. The Smart Radiator Valves look great too, with a translucent plexiglass Philippe Starck design and an e-paper screen for displaying the current temperature.   However, there’s a couple catches to my smart radiator valve dream. First off, while the Smart Radiator Valve lets you control temperature through ecobay’s app (or Apple Home...
  • The best smart radiator valves 2022 2022-11-17
    To control your heating from your phone on a room-by-room basis, you'll need a smart radiator valve (thermostatic radiator valve or TRV). Here are our recommendations.   There’s a reason smart heating is growing in popularity. Not only will it give you more control over the temperature in your home – so it’s always warm when you want it to be – but you can easily monitor your heat and potentially make savings on your energy bills. Still, we’d advise that you take manufacturers’ money-saving claims with a pinch of salt.   If you’re buying an entire smart heating system, it’ll take some time to recoup the cost of the tech but a smart radiator valve is a much smaller investment. Each one will allow you to control a single room, which means you can schedule heating so that it’s warm when it needs to be and no heat is wasted the rest of the time.   Being able to see the temperature clearly on your phone screen or on the de...
  • Thermostatic radiator valve 2022-11-17
    Thermostatic radiator valve A thermostatic radiator valve (TRV) is a self-regulating valve fitted to hot water heating system radiator, to control the temperature of a room by changing the flow of hot water to the radiator.   Conventional wax motor TRVa The classic thermostatic radiator valve contains a plug, typically made of wax (forming a wax motor), which expands or contracts with the surrounding temperature. This plug is connected to a pin which in turn is connected to a valve. The valve gradually closes as the temperature of the surrounding area increases, limiting the amount of hot water entering the radiator. This allows a maximum temperature to be set for each room.   As the valve works by sensing the temperature of the air surrounding it, it is important to ensure that it is not covered by material (such as curtains). If the controller is removed from the valve, the valve turns on and the radiator will always be hot.   Interaction with room thermostats Thermost...
  • How to choosing Zigbee or Z-Wave radiator valve (TRV) 2022-11-14
    Z-Wave radiator thermostats allow you to wirelessly control individual radiators. Each radiator can have it's temperature set and changed throughout the day - manually via a smartphone or based on timed schedules. The Z-Wave radiator valves allow you to have different parts of the house at different temperatures through the day, as you need it. You no longer need to heat empty rooms.   The Z-Wave radiator thermostats are fitted within minutes, they simply replace the existing TRV, no need to drain the system. Once installed they operate just like other Z-Wave devices, such as Z-Wave thermostats, as part of your Z-Wave smart home automation system allowing you to control them wirelessly from wherever you are. Or, you can use other features of the Z-Wave system to control them automatically based on time of day, or from other devices such as Z-Wave Sensors. This enables you bring smart central heating control to your home using your Z-Wave system.   If you've got questions abou...
  • Smart thermostatic valves based heat generator control to cut heating bills 2022-11-14
    The following work aims at demonstrating how a smart thermostatic (radiator) valve network can be used to reduce heating costs by controlling the heat generator (heat-pump, gas boiler, ...) in a more efficient way. Currently, a large proportion of heat generators is controlled by the means of a heating curve, or a similar rule-based logic that mostly rely on outdoor temperature or single point indoor temperature measurements. These simple control laws are in general commissioned to minimize the number of complaints of “cold users”. This results in high forward temperatures, that are energetically non-optimal as they create increased losses in the piping network and also have a negative impact on the heat generator efficiency.  In the proposed data driven approach, a controller was developed to ensure that the radiators receive fluid with the lowest temperature possible, while satisfying the heating needs. To achieve this goal, smart thermostatic valves are used to moni...
  • Controlling Steam Radiators 2022-11-14
    While studying for his Ph.D. in electrical engineering at Columbia University six or seven years ago, Marshall Cox regulated his room’s temperature in winter the way most New Yorkers with steam radiators do. He opened a window.   But then his twin brother, Jeremy, moved to New York to dance in “Come Fly Away” on Broadway. His brother complained “incessantly,” Mr. Cox said, that “it was boiling, or freezing, many times both over the course of a night.” It drove Marshall Cox to invent the Cozy, a radiator cover that can contain the warmth in an overheated room and shift it to an underheated room. The Cozy, which Mr. Cox has described as a “glorified oven mitt” and which is being sold on a limited basis, went on to win a $220,000 M.I.T. Clean Energy Prize in 2012.   The Cozy’s victory is understandable. It addresses a problem that has afflicted New Yorkers since the early 1900s, when oversize radiators were necessitated...
  • How do Thermostatic Radiator Valves Work? 2022-11-07
    The thermostatic radiator valve head is a quintessential piece of radiator technology. It is one of the many possible heating controls for modulating air temp across rooms. And due to its great value and easy function, it’s one of the most popular. You will find or fit your TRV on the side of your radiator, and correct set-up enables you to maximise a single boiler and enjoy different heats across different rooms. The TRV is a valve that self-regulates, meaning it adjusts the flow of water into your radiator depending on the setting. The thermostatic valve head goes on top of the valve body. And as the room temperature changes, the valve head expands, adjusting a pin in the valve body so that it opens or closes. Expansion as the room heats blocks the valve body to receive less hot water into the radiator. Contraction as the room cools opens the valve body to receive more hot water into the radiator. TRVs come in two main designs. They can be either wax or liquid models, with liqu...
