New homeowner (UK based) and getting to grips with all that comes with that. I previously only lived in a flat with a standard combi boiler, my new home seems to have an older system in place consisting of boiler + cylinder, but I would really like to understand how all of this works.
Now, I believe this system was upgraded throughout the years, as it includes a thermostat and a continuous flow of hot water (hot water is on demand, even when the timers are off, pictures to follow and questions at the end).
Thermostat, downstairs and central in the property:
Behind the above I found this scary thing:
What the heck is that and should I be worried?
Based on the above I suspect I have either system 2 or 3 of the video provided in the comments, but I'd like to confirm this.
Some things to note:
I seem to have hot water on demand, I thought I would depend on the timers, or setting it up via the "switchmaster", but we have hot water at any time of the day!
Once heating comes on, it will shut off automatically once temperature on the thermostat as been reached.
Considering this, I seem to have all the benefits of a combi boiler, just with a lot more stuff taking up space and more energy?
I also noticed the shower could use a bit more water pressure, a new shower hose and head helped a bit, but not quite there yet, is there anything on this system that I could do to increase water pressure in my shower? Would switching to a modern combi system help at all with this?
