Hi All.
We currently have this heating system whereby there is a cold water tank in the loft, the boiler is on the first floor in one of the rooms, together with another tank next to the boiler and an expansion vessel above the boiler, its a potterton boiler.
Now, the showers are both electric and mains fed, the only hot water taps we have are in the bathroom upstairs, the kitchen and a basin in the utility room.
In the winter the heating programmer was constantly set to on, so we used the thermostat downstairs to control the heating, but whenever the temperature goes lower than 21 it kicks in.
Last week, I changed this from the programmer next to the boiler, the model is a British Gas model UP2. From what I read, it allows you to program the heating/hot water to come on at 3 different schedules, so I did this for the heating only, morning/afternoon and evening.
What we noticed are as follows.
Is there a reason why the upstairs radiators are very hot when the boiler is only supposed to serve hot water?
Is it a good idea to leave the ot water set to ON or program this to a time, I dont like tampering with the heating system in case I make unintended changes ?
Thanks in advance.

- The radiators upstairs are always boiling hot even outside the heating programmed time. When this happens the hot water light is on.
- The radiators upstairs have always been hotter and faster at getting warm, we attributed this to the fact that the boiler is also upstairs, and I reckon 22mm supply pipes were used instead of 15mm.
- I dont understand what triggers the boiler to kick in for hot water, hence why I didnt change this to programmed time, I just left it at ON.
