Help: My thermostat needs an adapter
When I moved into my new flat in 2014, my electronic thermostats did not fit the existing radiator valves. I then did some research and found that information on suitable adapters for the large number of existing radiator valves was very scarce.
Over the years, this article with the big overview of adapters for thermostatic valves has therefore been created, which is updated and brought up to date at regular intervals. In this context, I would also like to thank the companies Kieback&Peter and eQ-3 AG/Staudigl, who have given me permission to use their radiator valve images in this article. Another thanks goes to the many readers who enrich this database with their pictures and comments.
Instructions: Fitting the adapter and thermostat
Before we start looking for the right adapter, you can see in the following illustrations how old thermostats are exchanged for new thermostats and adapters are used. It’s actually very easy, so don’t worry.
Tip: A Water pump pliers* is a suitable tool for dismounting the thermostats.
First we start with installation instructions for a Vaillant radiator valve with dimensions 30/30.5 mm, a corresponding metal adapter and the Classic L electronic radiator thermostat.
- Step 1: Carefully dismantle the old thermostat. Unscrew the thermostat to make it easier and loosen the screw ring counterclockwise. You can use a Water pump pliers* if the thermostat is too tight.
- Step 2: attach the adapter to the radiator valve using an Allen key (usually supplied).
- Step 3: After fixing the adapter, you can mount your thermostat on it. Then carefully tighten the mounting ring of the thermostat with the water pump pliers. That’s it.
In the second tutorial, reader Holger Schilling (see Holger’s comment (german Version)) has documented his thermostat replacement and shows how he successfully installed an adapter for a “Pont a Mousson” M28 x 1.5 radiator valve. Many thanks for the illustrations Holger.
Here, too, the thermostat is first dismounted and the adapter is attached to the valve. Then the new thermostat can be attached to the adapter and is ready for use.
FAQ – Questions and answers
Before we get started, here is a summary of the most important questions and answers:
Metal or plastic adapter for radiator valves?
I would choose a metal adapter as they are far more stable and have much better thermal conductivity than plastic adapters.
Why don’t the provided adapters fit on my radiator valve?
The enclosed adapter sets usually only fit the Danfoss valves RA, RAV and RAVL, as Danfoss valves are very common. If none of the adapters fit your valves, you do not have a Danfoss valve and need another adapter. This overview will help you.
How do I determine the connection / thread of a radiator valve?
The connection and the thread are usually specified in the form “M30 x 1.5” or similar. “M30” corresponds to a thread diameter (connection diameter) of 30 mm and “1.5” corresponds to the thread pitch of 1.5 mm.
Tip: A vernier caliper* is recommended for exact determination of the connections and thread dimensions.
What is the open dimension and the closed dimension of a radiator valve?
The open dimension corresponds to the distance from the thread to the end of the stuffing box pin when the valve is open. The closed dimension corresponds to the distance from the thread to the end of the stuffing box pin when the valve is closed.
There are no adapters for my valves. What can I do?
If there are no adapters for your valves, the only option is usually a valve replacement. However, this can be carried out by a specialist company without any problems.
Note: When replacing the valve, your heating system does not have to be drained! It is possible to freeze the pipes locally and thus have the valve replaced by a specialist company. The following video is an excellent demonstration of the principle of local icing:
Overview – Adapter for thermostatic valves
In order to find out which radiator valve you are dealing with, I have tried to create a suitable overview. Many of the pictures are from the eQ-3 overview, which is really recommended: “Compatibility of electronic radiator thermostats with standard radiator valves (German Version)“. Another large part of the pictures comes from the comments of this or the german version of this article, which were uploaded by you, the many readers. Many thanks for that!
Below you will find the overview of radiator valves sorted alphabetically with pictures of most radiator valves as well as the matching adapters and partly also with associated thermostats.
Tip: I recommend using a vernier caliper* to determine the exact connections and thread dimensions and a Water pump pliers* to dismount and install the thermostats.
Adapter for Comap / SAR valves – M28 x 1.5
In addition to the radiator valve Comap / SAR M28 x 1,5, there is also a valve from Comap / SAR with the thread dimension M30 x 1,5.
Note: No adapter is required for the Comap / SAR M30 x 1.5. You will find this in the section “Radiator valves – no adapter required!“
| Valve | Connection/ Thread | Offenmaß [mm] | Schließmaß [mm] | Adapter |
| Comap /SAR | M28 x 1,5 | 10,7 | 8,3 | JA |

Adapter for Ista (Oventrop) valves – M32 x 1.0
For a long time, the energy service provider Ista had its own radiator valves and thermostats in its product portfolio. These had the thread dimension M32 x 1.0 and were most likely manufactured for Ista by the company Oventrop. This can be recognised by the fact that the imprint “OV” (stands for Oventrop) can be seen on the Ista valves.
The Ista M32 x 1.0 is therefore most likely identical in construction to the Oventrop M32 x 1.0. For this reason, the Oventrop Thermostats Uni LI ISTA* also fit the Ista valves and the Ista adapters fit Oventrop M32 x 1.0 valves.
| Valve | Connection/ Thread | Open dimension [mm] | Closing dimension [mm] | Adapter |
| Ista / Oventrop | M32 x 1,0 | 15,3 | 11,5 | YES |
Thermostats without adapter: The following current Thermostats fit on the Ista M32 x 1.0 valve:

Adapter for Rossweiner valves – M33 x 2.0
The Rossweiner company produced under its own brand until 1998, since then it has belonged to the Aalberts Industries Group and was assigned to the Meibes Group within the corporation in 2008. The original Rossweiner radiator valves had a thread size of M33 x 2.0. Today, radiator valves and thermostats are still produced under the Meibes Group, but these have a thread size of M30 x 1.5 according to the factory standard.
Note: No adapter is required for the Rossweiner M30 x 1.5 according to the factory standard. You will find this in the section “Radiator valves – no adapter required!“.

Adapter for Vaillant valves – 30/ 30.5 mm
The heating system manufacturer Vaillant also no longer has its own radiator valves or thermostatic heads in its product portfolio. The original Vaillant radiator valve had the dimensions 30 / 30.5 mm. Since I have also installed Vaillant radiator valves in my flat, I can say that the adapters for Vaillant valves work very well.
Note: There are no adapters for the Vaillant M42 x 1.5. You will find this in the section “Radiator valves without matching adapters“.
