The worst part of living in the UK is figuring out the utilities and equipment.
I am having trouble with my hot water. It is either the hot water tank (which is rumbling as it usually does so it is likely just fine) or the boiler. I have to figure out which, decide if I can fix it or need to call a plumber, and then decide if I call on Monday (a bank holiday and twice the price) or risk no hot water for 24 hours. I can shower at the gym, I can boil water, but I am CRABBY about having to deal with this.
