A few questions

Hey everyone ive been here before but i wondered if you could help me with a few questions. Well to cut a longstory short a new central heating boiler being put in meant we might have space for a dishwasher 😀 , however there is always a but and this is where my questions come in (ive put them in a list to try and make them less confusing lol):

1. is it okay to put a dishwasher below a boiler? there would be about 8 or 9 inches of space between the two if my measuring is correct

2. the plumbing brings with it more problems as the dishwasher would be around 3 meters from the drain and water line, for the water inlet i was originally thinking of getting a long extension hose but i thought about getting a plumber in to extend the cold water line about 2 meters, any idea what this would cost or is this the wrong place to ask?

3. for the drain it wouldnt really be possible to bring the pipe work closer to the dishwasher so from what i can see my options are: A. extend the dishwasher hose and put in another adaptor so it can go in the u bend under the sink like the washing machine or B get one of those self cutting drain adaptors and connect it to the drain line just before it goes through the wall into the soil pipe, but would the dishwasher be able to pump this far, its approximately 3 meters.

4. The floor where the dishwasher would go is slightly uneven as some of the tiles have come up. would i need to get this perfectly level to make sure the dishwasher would work properly.

5. i was thinking of putting some cork tiles down to help deaden the sound of the dishwasher as i dont know how loud they are. would this help?

6. in terms of what dishwasher to go for i dont really want to spend more than £250 and was looking at the bosch range, either the SGS45C02G or the SGS43T72G. are there any other dishwashers you would reccomend or is my choice fine? i know to stay away from anything indesit, hotpoint or cheap chinese brands from reading other posts

7. the space for the dishwasher door to open would be tight and i have measure up the bosch dishwashers and with the door open i think they are approximately 120cm deep which would just open without hitting the washing machine which would be opposite to where the dishwasher would be. I one the bosch website for accurate measurements with the door open but couldnt find any. I wondered if any of helpful people here know the measurements, i asked before but nobody knew its just my measurements might be out as i didnt want to hang around currys too long as i was getting some strange looks opening dishwashers and trying to measure them lol.

i have got a word document where i have drawn out the kitchen layout and where the dishwasher would go and plumbing etc. but i dont know how to put it in this message.

Cheers in advance if you can make sense of my rambling but i tried to give as much detail as i could lol.
