Balancing radiators without thermometers

After reading various DIY guides and articles on how to balance a radiator based heating system, I came across an interesting, but in-depth guide on how to do this without the cost of using thermometers, let alone hiring a plumber.  In my guide here, I aim to summarise the process, which is a little different to the original in-depth guide, but worked well for me despite me not being a plumber.

Despite all the rain here in Ireland, it does get warm from time to time, often to the point where it is difficult to sleep at night.  However, what is more surprising is that I see people using air coolers that can actually make their environment even worse, not realising how these operate!  So in this basic guide, I’ll go through the types of appliances and where they work best and why air coolers are not really useful in the Irish climate.
