Default Accounting for Water Temp drop when adding grain

So, let's say you have 8 pounds of pale malt. Intended temperature of the mash is 154.

Well, how hot do you get your water above 154 to ensure the room temperature grains don't lower the temp too much? I hope that makes sense. Is there a calculator for pounds of grain + their temp + intended mash temp so you can be sure you don't get too low?

There are LOTS, here is one of them: http://www.brewheads.com/strike.php Lots others... do a google search on strike water calculator. Also, beersmith has one.

It usually ends up calculating to about 6 degrees, assuming your grains are at room temperature.

BeerSmith makes this adjustment automatically. I just print out the recipe and follow the instructions.

I have used a couple of calculators and ended up not hitting my target mash temps so I quit bothering with those. I think the amount of insulation and the type of container has a great effect on the temp, so for me personally, It was just doing a few batches, recording my temps, and adjusting my mash in temps from there. I also stick my mash tun in the sun while my water is heating to get it nice and warm before mashing in, unless its a hot day, then I make sure its in the shade.

Beersmith is a good investment.

Calc's the water temp for you, adjusts batch size, converts to extract if you want, stores recipe and notes.
I run it while brewing and use the timer for the mash and the boil.
Lets you know when it's time for each addition.

Yeah, BeerSmith does it, but I have to take their numbers and add 2° (and then I'm usually balls-on). I'm sure there's a way I could adjust. It's always going to be somewhat dependent on your system and processes (cooler MLT versus a keggle, how quickly you stir in your grain, whether you preheat or not, etc.) But, BeerSmith will help in this regard and is a great investment for all sorts of reasons.

Beersmith seems like a bit of a pain to get your equipment profile dialed in on.
That seems to be the general opinion on beersmith's site also.
I think most people do like you did and just learn how to adjust what it tells you.

I'm going to add another mash tun so I'll see how it does with a five gallon tun when it is big enough.
I bet that between the lack of dead space that I have in a ten gallon tun and filling it with hot tap water ahead of time it hits pretty close.
