Hi all, Found this forum whilst looking for info on TEC / Peltier devices.
I'm hoping to build a Fuel filter pre-heater so I can run my diesel engine on vegy oil.
All I need is way of pre-heating the oil in the filter until the engine has reached running temp.
I was wondering if a simple 12 Volt circuit with a thermostat connected to the TEC would work.
I just dismantled a 12V cooler box that uses TEC's and all they have is a thermostat that cuts the power when a certain temp is reached.
Can it really be that simple, I have read about control circuits being needed, but it seems these are for systems that need temp control, am I correct in assuming this ?.
Also, I have read that switching these devices on and off repeatedly can damage them, would it be OK to use a thermostat, where switching would be limited to once or twice a minute ?.
Sorry for all the questions, I,ve only just discovered TEC's, was amazed to find out they've been around for over a century.
Hope someone can help, Thanx for reading.
Rob.
