  1. ECOCAL™ THERMOSTATIC RADIATOR VALVES

    Thermostatic valves are typically used for regulating the water flow to the radiators of central heating systems.
    A thermal regulating element automatically controls the opening of the valve to keep the ambient temperature of the room where they are installed constant at the set value.
    This prevents unwanted temperature changes and achieves energy savings by keeping the temperature constant

  2. ECOCAL™ TWIN PACKS

    The Altecnic range of radiator valves are of durable construction giving dependable performance for building services and domestic applications.
    Their aesthetic design satisfies the requirements of modern commercial buildings and domestic interiors.
    Chrome plated bodies with white thermostatic controllers and lockshield covers give an unobtrusive appearance and complements most decors.
    For more stylistic modern decors valves are available with chrome finish thermostatic controllers and lockshield covers.
    The inlet connection of the valve body is either compression or push fit for use with copper tube.
    Supplied with manual cap for stem protection and manual isolation. 
    Altecnic thermostatic radiator valves are BS EN 215 certified.

  5. DYNAMICAL® TWIN PACK

    The DYNAMICAL® thermostatic radiator valves allows the automatic dynamic balancing and pressure-independent adjustment of the thermal medium in the radiators of two-pipe heating systems.

    The device, in conjunction with a thermostatic, electronic or thermo-electric controller, combines different functions into a single component.

    The use of dynamic thermostatic valves in combination with thermostatic control heads makes it possible to keep the ambient temperature constant, at the set value, in the room where they are installed, thus guaranteeing effective energy saving.

  6. COMMERCIAL PRE-SETTABLE THERMOSTATIC RADIATOR VALVE

    The Altecnic range of pre-settable radiator valves are suitable for use with the ecocal manual handwheel operator or thermostatic controller.
    They are used to control the room temperature by regulating the flow of hot water into the radiator or other heat emitter.

About our Radiator Valves

What is a thermstatic radiator valve?

Thermostatic valves are typically used for regulating the water flow to the radiators of central heating systems. They are self-regulating, containing an element which automatically controls the opening of the valve. This maintains the ambient temperature of the room to the value at which it is set, preventing unwanted temperature rises and achieving considerable energy savings.

Ecocal TRVs are particularly ideal for use in conventional twin-pipe heating systems where the level of temperature control needs to be more accurate than is available through a manually operated valve. These models have been carefully manufactured for either retrofit or new installations and have a reversible body for either horizontal or vertical fitting. Suitable for installation on either flow or return pipework, these TRVs provide the installer with flexibility.

How does a thermostatic radiator valve work?

Thermostatic radiator valves consist of two main parts: a thermostatic head which senses the air temperature around it, and the valve body. Together, these regulate the flow of water through the radiator which they are fitted to.

Inside the thermostatic head is a sensor containing a wax or liquid material which expands as the room temperature warms up, and contracts when it cools down. The sensor is connected to the valve which moves the seat inside the body to open as the sensor expands and closes as the sensor contracts.

As the valve opens to allow more hot water from the boiler through the radiator, more heat will be given out by the radiator. As the valve closes and restricts the flow through the radiator, less heat will be given out by the radiator. It is important to remember that the TRV does not switch the boiler on/off, it only regulates the flow of the available hot water.

What do the numbers mean on a TRV?

It is a common misconception that the numbers on a TRV relate to the temperature of the radiator, e.g. the higher the number it is set to, the higher the temperature of the radiator. However, this is not the case. The numbers on a TRV actually relate to the target temperature of the room. Each number roughly corresponds to the temperatures below:

0 = Off

* = 7°C

1 = 10°C

2 = 15°C

3 = 20°C

4 = 25°C

5 = 30°C

What number should I set my TMV to?

As you can see from the temperatures listed above, it is generally not necessary or worthwhile to have your TMV set to 5 in the winter. By setting it to 5, you are telling it to continuously let hot water through until the room temperature reaches the upper limit (around 30°C). This will result in higher energy consumption and, therefore, higher bills.

To ensure you’re using your energy efficiently and to save money, we recommend setting your TMVs to a comfortable room temperature (generally in winter this would be 2 or 3) and letting them do their job.

If you are away for a long period of time over the winter, we recommend setting it to * (usually depicted by a snowflake or full-stop) to ensure radiators come on when temperatures drop below 7°C.

Note: for the frost setting to operate, the heating system must be turned on.

Does it matter where thermostatic radiator valves are fitted?

Yes, to provide good control and save energy, it is very important that TRVs are mounted in ‘free air’ and not blocked by furniture, curtains, or enclosed within decorative cabinets. The TRV can only work to the temperature that it can sense.

What is a TELL rating?

TELL is a product classification system of the European thermostatic radiator valve industry, which fulfils the increasing and understandable desire of consumers, both in Europe and worldwide, for information and guidance in making a conscious purchasing decision. The system supports the industry's desire to promote responsible consumer energy usage.

Ecocal TRVs from Altecnic are classified to TELL ‘A’ rating, making them the most highly efficient TRV.
