how long does it take your printer heated bed to heat up?

my Rostock max is my fastest heat-up bed machine. it gets to 70deg c in about 5min.
i was told that some machines were a lot faster at bed heat-up to temp. i find it hard to believe. i was wondering what the average bed heat up is for various machines.

what i was curious about times for other machines in the last few years. just checking if 5min is about average.

if people can post type of machine and model and about how many minutes it takes to heat up. i'll post results to a reprap page about bed heatup times if there are more than 10 responses. i could not find one already.
plate thickness contributes to time. i know theoretical heat up times, but theory is only theory.

this was a good idea to reference theory of heated beds jscalc.io from a comment below. but theory is only theory. i hope to get several samples to compare. from standard machines to big ones, whoever provides estimate times it will be much appreciated.

edit:
can you mention the machine model custom or brand name and heated bed size. this way i can categorize them, thanks.

This calculator does a pretty accurate job of calculating the heat up time based on size of the bed and power applied: [jscalc.io]

My 300x300x8 mm cast aluminum bed with a 750W heater heats to 100C in about 4.5 minutes.

Sorry, I can't tell you the exact time, but I was able to significantly improve it by insulating the bed.

Example:
ASA printing requires 110C on the bed.
Initially I had hard time reaching it, because Marlin would time out waiting on temperature advancement.
Then I calibrated bed PID and increased Marling per/degree waiting threshold.
I was able to reach the temperature, but it took forever.
Bed insulation reduced bed heating time by approximately half.

One other suggestion is to keep the printer away from drifting air flows like those created by opened doors or windows.
Good ambient temperature helps too.

HW:
I use 24 volt, 350 watt PSU and 300x200 heated bed.

It is under 3 minutes after bed insulation

I also get 2.5 minutes with an insulated bed

My 300mm square x 5mm thick aluminum plate with a 150W, 12V silicone heater taped to it with that 3M high-temperature double-sticky tape, backed by aluminum foil and cardboard insulated will heat to 75C in about 6 minutes. I am the slow poke here. smiling smiley

My 330x330x6mm tooling plate with 300x300mm silicone 750W AC heater pad takes about 3-4 minutes to get from 20 degrees up to 105*C. I sometimes use fans to blow over the heated bed to heat the enclosure up a bit, so that takes slightly longer. There's no insulation under the silicone pad, so it may get faster if I do.

Insulating the underside of the bed speeds heat-up time and slows cool down time.

My Hictop 3DP12 24v heat-up bed machine. it gets to 96C in about 4.5 min.
My Hictop 3DP11 12v heat-up bed machine. it gets to 96C in about 6 min.

May try to add some insulation to speed up the heat times.

My Kossel XL variant (see link in my signature) takes 2 minutes to heat to 80C. It uses a 5mm x 330mm diameter aluminium bed plate with a 350W silicone heater.

thanks for the info so far. i hope to get enough to show a list or a chart. don't be scared, i'm just looking for a range. some people have really fast heaters, but generally it is 12v or 24v.
some people have quicker heat up times using insulation. this is also good info. thanks for those who have contributed times and heater setups and printer models so far.
