A hot water repair service does what they say on the box and that is of course to fix your hot water
. This will often mean repairing a broken boiler which can have a range of reasons for being broken for instance often a broken boiler is a result of a build up of pressure. In other cases it might be that the boiler is heating up your water but just that it is not properly getting it around your home. This is often a result of a broken pump and that is a particularly frustrating way for you to lose your heating because it means that you are still using a lot of electrical energy (and therefore money) in order to heat up the water but you aren't getting anything out of it.
If you have a broken boiler or otherwise broken hot water then this is something that can make life almost a misery and that can affect many different aspects of your life. First and foremost this is frustrating because it obviously means that you won't have any hot water for bathing in or showering in. For some people this then means that the only solution is to stand under the cold water and to be frozen. This is particularly horrible first thing in the morning and can place a nasty strain on both your heart and on your immune system. For those who are elderly or who have existing heart problems this can be dangerous and enough to cause a heart attack.
At the same time if you have no hot water then this will mean that you are forced to wash your hands with cold water. That is simply not as hygienic as washing your hands with hot, as the hot water normally acts to partially disinfect your hands by killing off bacteria (which is why we boil food). This then means that you are more likely to get ill and feel run down if you don't have any hot water, and bacteria such as the staph virus is more likely to come into contact with broken skin or hair follicles where it will be enough to cause serious problems.
Another thing to consider when using hot water is that you use it to wash up your crockery and cutlery. This then means that with broken hot water you have messier plates and that in turn means that you will end up being more unhygienic still. This can even create a smell. And you wash other things with hot water too (or you should) from floors, to your car, to other surfaces and this means that you will have a whole home that is starting to look dirtier and to be more unhygienic. This is then why it's so important to get hot water repair as soon as possible if you have it so you can look after your health, your home and your quality of life. Lying down in a newly run hot bath for the first time will never feel better...
