    How to use temp difference in 2 tanks to start pump

    If I don't have some kind of regulation here the worst case scenario would be to get 80 degree C warm water circulating in my floors - and that I don't want. :)

    How to use temp difference in 2 tanks to start pump

    Thanks again. I'm in the process of designing a system for water based heating in the floors of a family house. One of the tanks will be an accumulator for the floor heating water. This tank will mainly be heated by a heat pump. The temp in this tank will be approx 35 degree C (the temp will...

    How to use temp difference in 2 tanks to start pump

    Many thanks for your answers. It seems like a good idea to put two temperature transmitters back to back, and do regulation based on the polarity of the signal. But the transmitters I've dealt with so far have had to be put into a serial circuit with a voltage source. With this configuration -...

    How to use temp difference in 2 tanks to start pump

    Hi, I have two water tanks A and B. The temps in both tanks can vary independently. Both tanks can be equipped with a temperature sensor. What I want is an electrical pump to start when the temp of tank A is higher than the temp in tank B. What setup/equipment do I need to achieve this. I know...
