As I will be replacing my boilers with a dual fuel unit soon,
I was wondering how many of you have been using the
Hydrostat 3250 with the external temperature sensor kit
and what problems you have found with them if any?

    I have used a few. I just installed one today on a new boiler. The biggest complaint I have is that there is a lot of wiring that has to fit into a tight space. I found myself using a pair of needle nose pliers to fit all the wires into the slots....I don't have big hands.
