Great Video Gas Man, nice for you to put the time in to make it.

Below is a copy of a table I found online which I have referred to in the past and found to be quite accurate. It lists different boilers and their thermistors with expected values.

I have not made this myself, but didn't want to link to another site, therefore don't blame me if any of it is inaccurate but use it with common sense. As said it is, in my experience, accurate and reliable (haven't come across every type yet though)

Hope that helps, if you copy and paste it into word or similar you can print it off and keep it in your van.

Just to add, for those who don't know already. an NTC thermistor is Negative Temperature Co-efficient which means as the temperature rises, the resistance drops. A PTC thermistor is guess what? Positive Temperature Co-efficient which means as the temperature rises, the resistance increases.

Nice one Mark. I don't have a problem with testing thermistors, just getting to the bloody things!

 

[Billy Bob Bob]

i try to keep the harnesses off old combis,easier to test could not find any for the video though

 

[TBServices]

I'll be salvaging them from now on.

Any suggestions for NTCs to keep in stock on the van? Common ones/ones that will get a lot of boilers going?

ferroli white and green plugs,baxi white and black plugs,ariston green plugs are the ones i keep

 

[TBServices]

Any of them fit multiple boilers?

The vokeras are common round here so it would prob pay to keep those on

 

[Billy Bob Bob]

ariston fit some worcester baxi ones work throughout the range

 

[mfgs]

Any of them fit multiple boilers?

The vokeras are common round here so it would prob pay to keep those on

I look after a lot of sabres/vokera's. The primary thermistor on the vokera compact/sabre HE is a very common fault.

What was the website any more gems like that on it?

 

[manic26]

Nice one Mark. I don't have a problem with testing thermistors, just getting to the bloody things!

That's right very awkward most of the times

 

[TBServices]

I look after a lot of sabres/vokera's. The primary thermistor on the vokera compact/sabre HE is a very common fault.

Is that the 8484 or the 7022?

 

[Billy Bob Bob]

think i have used a baxi one on a vokera that was a band b cant remember what model though

 

[TBServices]

Will they work most of the time if it fits in the pocket/thread and the connectors? You know, while you wait for the correct part?

no its resistance is critical,if say the vokeras is 15k cold and the baxis 11k there will be issues

 

[TBServices]

Thanks for clearing that up mark 🙂

10027352 is the part number I think of the one that goes. On the right hand side of the primary heat exchanger.
