eTRV Remote Controlled Motorised Radiator Valve

Description

The eTRV is the latest innovation in automation of Thermostatic Radiator Valves (TRV). The eTRV replaces the head of your existing Thermostatic Radiator Valve and provides you with both time and temperature control of your room, all set from the handy remote control included with the eTRV. The eTRV offers three programmes each day that maximise the savings on your energy bill. The manufacturer's tests suggest that a 25% reduction in energy is a realistic possibility when you change from your old TRV to the new eTRV.

How does the eTRV work?

• Unscrew the head of your Thermostatic Radiator Valve (don't worry - water won't come gushing out).
• Screw on the eTRV (adaptors are supplied to fit most common valve bodies).
• Insert the batteries (supplied).
• Set the times you want your room to be at the desired temperatures using the supplied remote control.
  

Operating the eTRV is simple, using the remote control handset supplied. Large, clear numbers, along with easy to understand instructions allow you to program the eTRV with up to three cycles of temperature change per day. Different cycles can be used for different days of the week (for instance having higher temperatures or different timings on the weekends to the weekdays).

Smarter and quieter

An old fashioned style TRV has one temperature sensor which is supposed to detect the room temperature. In reality it is also affected by factors such as whether it is fitted horizontally or vertically and whether the valve is open (so there is hot water in the pipe just underneath it) or closed (so the pipe beneath it is cool). Unlike a conventional TRV, the eTRV has two temperature sensors. The top one senses the air temperature in the room while the second sensor at the base senses the temperature near the radiator flow pipe. The eTRV then calculates a temperature offset which results in a far more accurate control of room temperature than a conventional TRV.

One of the problems with motorised TRVs is that they can be noisy. The manufacturer of the eTRV claims that independent tests have verified the eTRV to be the quietest product on the market - the motor is hardly audible (though some noise will inevitably attenuate through the radiator and pipework). Part of the higher cost of this product over comparable products is the need for the higher specification motor and well engineered gears that keep the noise level to a minimum.

Compatibility

The eTRV fits to the valve body of your existing Thermostatic Radiator Valve. If you do not have a TRV on your radiator you will need to get in a plumber to fit one first. The eTRV is supplied with 28mm and 30mm adaptors to fit most valve bodies with those screw threads. The eTRV is compatible with valves made by:

• Barlo
• Braukmann
• Drayton
• Honeywell
• Landis & Gyr DuoGyr
• Myson
• Pegler
• Regis (B&Q)
• Siemens
• and many others.

The eTRV suits both horizontal and vertical valve bodies.

The UK built eTRV continues to sweep up awards for its innovation and ability to challenge carbon reduction. In November 2010 the eTRV received overall winner in the Innovation Award category of the Energy "˜Buying & Supplying "^TM Excellence Awards beating Marks & Spencer and the Ministry of Defence.
