pull bag after rest?

Doing a hefeweizen recipie that calls for a 110 rest.

My set up is under powered with only 1500watts so heating is slow.
it would probably take 30-40min to get from 110 to 152.

Should I pull the bag out or can I leave it in? what are the risks

Don't do the rest at 110, unless you can bring it up to temperature quickly.
The 110F temperature rest is a ferulic acid rest, is said to help give that 'clove' flavor to the hefeweizen. But you can get that from the yeast.
A single temperature rest would be better than a very slow rise to a saccrification rest.

It's that ferulic acid the yeast uses. If you want a clove-forward one, I wouldn't skip the rest.

If It'll take too long to heat directly, go the multiple infusion route. Or do decoctions. Or a smaller mash volume. I assume since this is BIAB section you're full volume mashing which is going to work against you greatly.

Why not add another 1500 watt heater so it doesn't take so long to heat up the wort? For example:

By the overall dimensions listed for that device it looks like portions of it that are not meant to be immersed could be under water for a "normal" 5gal batch of beer (depends on kettle). A bucket heater seems more appropriate for the volumes normally associated with home brewing.

If you have another 2-3 gal kettle to boil water in you could do a mash in with 1:1 ratio (1 qt per lb) then add the boiling water to hit 152 in seconds instead of minutes.

Use the "rest calculator" on the Green Bay Rackers website to determine how much boiling water to add to bring your temperature up:
