Ok seriously man, with all due respect, how are we supposed to answer a question like this? Will your floor be able to hold a 210 tank? How am I supposed to know? Is this "floor" on the lowest level of your house with a concrete slab underneath? Maybe you have a basement and this is technically the 2nd floor of the house? If it is a 2nd floor what direction do the joists run? How big are they and how spread out are they? Do you live in an area of the country that might have special regulations, such as a coastal area with sandy soil and high water table or maybe a colder area?
Also, why does it matter if it is facing the front door? It's not like having a tank face a door makes it explode but having it face a window makes it thrive. Seriously, what good is this information? Even if this was important, how are we supposed to know what this means? My house is almost certainly not the same design as yours. "Facing the front door" is going to mean something different to everybody here.
Now I really don't mean anything bad by this. Please don't take this the wrong way. It can be hard to know what information is useful to include if you aren't experienced in that area (and when you are, you don't need to ask the question). We really don't know anything about your situation though and nobody can give you a remotely acceptable answer.
Regardless of the information, this is really something that needs to be done in person. Many things will come into play and there just isn't a way to do this (properly) online. I would highly recommend spending a few dollars to have an expert come out and take an in-person look at the area in question. If you don't know any try calling the village/city office where you get building permits and asking them who you should call. The small amount of money you spend now could potentially save you tens of thousands of dollars by avoiding a huge disaster and is well worth it.
geez no need to yell at me:nope: i thought that maybe it would help to tell u that it was in my foier room by my front door. Ok so my tank is on the first floor underneath the tank is a unfinished basement with obvioulsy concrete floor, there is no support beams under it, all there is are about 6-10feet boards laying across held by wut i think is a joist hanger and the boards run intersecting the tank. Calculate this i measured how much water is in the tank the length is 72, tha depth is 24 1/2 inches and thewidth is 24 inches, and if i did the correct math there should be a total of about 183 gallons. if i can ill post a pic of were its located.
