I am assuming that you're using 220VAC as well then? Did you integrate any thermal fuse or something similar? I find it somewhat troubleful to think of a thermal fuse (the ones I have here simply burn if T>200°C and would be connected in series to the silicone heater) connected to the aluminium bed.Quote

500W is a good power level for about 300 x300 mm plate. My machine has a 450W heater and is about that size and gets up to 105C for printing ABS in about 5 minutes.
For what do you need the bed clips exactly? So far, I printed directly on my (former) aluminium bed. Do you have an additional surface on top (e.g. glass)? Actually, that would be the best combination between a persistent print bed and the modularity of a removable one, I guess.Quote

The heater is smaller than the aluminium plate by 15mm all round to leave space for fixings and bed clips.

How do you control it? In normal thermostatic mode with relay or SSR or with some kind of PWM and triac?Quote

Yes I use a 230VAC bed heater.

I'm just curious as I'm thinking about multiple fan control and measure board with mains relay for 24VDC PSU and 230VAC heater bed triac.
I have this idea of putting my yet to be built printer inside a box, put some air through the electronics and motors to cool them and then filter it out the heated air with active carbon.

I've seen your megamax and all the particular description!(GREAT JOB!!)Quote

How many people actually need to swap glass plates? Really? When I was a kid I was impatient and would have wanted to throw another plate on there to start printing again right away. Like wine, I've matured with age, and don't mind waiting a little longer for a print to finish. I find I'm also much more particular about the quality of the parts, too, and that usually means printing at a leisurely 40-50 mm/sec. The world won't end if I can't start printing another part 30 seconds after I finish printing the last one. When printing parts that take hours to finish, what's a few more minutes more or less for the bed to cool off and warm up again?
You can see that people who bought PEI use this adhesive (read comments)http://www.amazon.com/gp/product/B00CPRDDLY?keywords=PEI&qid=1457768582&ref_=sr_1_1&sr=8-1Quote

I'd look it up anyway, just to be sure. People make mistakes that get copied by others all the time.

A more modular possibility would be using a glass layer with a PEI layer on top of that (again, put on the alu plate).

......and do you think that I can use this adhesive also to fix my 30x30cm silicone heater on the bottom of cast plate?Quote
So based on the manufacturer's specs, I'd say that tape looks OK to hold the PEI on the bed plate.
