    But you can use a separate thermostat to control a simple (non-thermostated) water heater.

    Here is a link (for a iron perchloride heater) :

    It's to everyone to see if the added costs of separate thermostat + heater (total about €50,00) stays in the "reasonable" price zone.

    Best regards,

    Yes, (sorry I didn't remember how "perchlorure de fer" is said in English)
    In fact, it is sold as remplacement part for a vertical etching PCB machine.
    I think it can heat liquids up to 50°C.

    Today I was in my local aquarium shop and the most powerful heater I was able to find (a 400w) is only able to mantain 34°C...

    Shame!!!!
    Plus the submersible pump I bought for my hydroponic ebb&flow setup can run only up to 35°C, so even if I wanted, I'm unable to use it as a recirculating pump in the tempered bath.

    I developed Fuji 400NPH for a while at 86F and found a green cast in the shadows in the finished prints. I spoke to Fuji and Tetenal about it and was recommended to revert to 100C processing at the standard time. Since doing so the green cast disappeared. Nova sell replacement heaters for their processors- you should contact them
