Constantin:
As for condensing dryers, all of them are based on electric power and are generally less efficient than their non-condensing platforms. The sole exception here being heat pump dryers marketed by Bosch and others in the EU, but not the US (at least, not yet).Now a quick suggestion for the OP: Before you rip out the old control system, etc. may I suggest you install all the sensors we talked about and then log the different behaviors of the control system. That gives you a baseline to compare your dryer performance / algorithms to. Just a thought.
I tend to disagree a bit on condensing dryers, they should be a bit more efficient as they do not just dump the heated air to the outside but recirculate the air inside over the condensing unit and back to the drum. outside air/room air then passes over the condensing unit on the other side and cools it down hence the water in the air on the drum side will start to drip off in a container for my machine, others just let the water run out via a small pipe. i have attached a pic of the condensing unit itself, easy to take out as you need to rinse it once a month or every 3 months, i just take mine with me in a shower.
but yeah placing the sensors before ripping the control was also my plan, at least i can mimic the cycles allready there and then change them to the better.
