GT106 flow switch

I have a Boilermate 2000 with a retro-fitted GT106 flow switch. Its in series with the plate heat exchanger pump and prevents the pump running continuously when the PCB is calling for heat even when taps are closed. It was added by Gledhill themselves after I made several observations and complained about the effectiveness of the solarpod the Boilermate 2000 was supplied with.

Unfortunately the flow switch is now U/S. This is fine in summer when store and plate temps often exceed 75C, however it becomes a problem in winter when the pump running continuously destroys any thermal stratification and the solar doesnt operate.

It seems the flow switch is no longer available. Des anyone know where i might get one, or alternatives?

Thanks in advance.

PS I know the "solutiin" is to turn the gase on and leave the store at 75C continuously, but allowing the store temperature to drop during the day lets the solar do the most it can.

A company called Adlink have one on Ebay item number 364412130987

Hi, thanks for the reply. I've been watching that flow switch but it doesnt look like the one I have which makes me thnk I was given incorrect information. Do you recognise the attached flow switch from other Gledhill systems?

The Gledhill one looks very similar to this: https://www.ebay.co.uk/itm/256042818017 or even this (with no wires) https://www.ebay.co.uk/itm/256000234008 - which is probably worth a go at 25% of the cost! No mention voltage / current ratings though.

I would definitely give it a go for the money, I doubt there will be any voltage or current issues.
