Bathing Solutions

I have just struggled for the last week wondering how I would get a proper wash. My brain gets very depressed if I don't shower or bath in HOT water.  The last time I was without a bathroom, shower or bath I went to my former partner's house every few days but he has sold up!  I could go round to a different friends' house as suggested but I don't like to intrude on family life.
The last time I was without the bath / shower facility I had hot water from a boiler plus with kettle water I filled two orange BnQ diy buckets and went to the outhouse where I had heated (no, NOT HEATED!!) the room with the electric radiator that is out there on the wall!  The temperature outside was minus 26C.
This time I have no hot water as the water boiler has broken and it has been noisy since October 2014.  The installer eventually came in May 2015, said he would contact the manufacturer and despite my phone calls never spoke to me again. In August the machine twice cut the general electricity in the house. I had been putting it on only when we needed bath water every three days as it made such a terrible noise.
Then I was told that the compressor is dead.  It has been installed in a room too small in cubic space. It has been installed without sufficient ventilation.  It was supposed to be energy efficient but hasn't been!  Now I await the third company involved to send me the devis (estimate of costs) to make it function.. it will soon be five years old! They say the manufacturer is involved but my French is struggling to fully comprehend. I WAIT!  I have been told I have no choice!  But surely, there is always choice! Eventually I shall need someone who is fluent at French  to speak to the original installer but when I know MY FACTS!
After one week, last Saturday, desperate to wash my hair, I spent a long time...about an hour ... heating a one litre kettle of water many times.  Then I thought 'let's try the micro wave oven' as my friend has recently given me one and all week I have been trying to use it!  Never had one before!  I have some small plastic bowls and the micro oven took 8 minutes to boil the water in a three litre one.   So that made the process quicker.  Meanwhile, the towel radiator was warming the room nicely!  Eventually, I had two and a half buckets, which with a little cold water was enough to sit in the bath and pour hot water over my head bowl by bowl. After which it was glorious to lie in less than two inches of water and splash about!
What a palava! Makes me appreciate water... and electricity... and how much water I am saving on the meter. That is a good thing because last six months bill was high. I had on two occasions left water running from the kitchen tap overnight!
