Hi,
This is a completely new install so a clean slate. Selections so far are
mains gas
vented hot water tank
My reason for vented is I have the head room in the loft to get >1m below the cold water tank so vented allows DIY and I have a defined flow rate independent of what the mains water pressure/flow might be (I've no idea if it is good or bad). The house has a few bathrooms.
Next choice is CH, is this regular (F&E tank) or system. I read that F&E is, according to one web site, still better - no regular fills, etc., less to go wrong. The boiler then doesn't come with a pump but maybe that is a good thing. I did look at system to start with but seems they are pretty much equal. F&E needs loft tank but then system needs water bottle and additional expansion vessel too as well as the one in the boiler. So is F&E best?
And which make? I've seen worcester-bosch and valiant suggested. I've been looking at the 30CDi and 30Ri. I would have thought there would be a hot water heating setting triggered off the HW cylinder thermostat but I can't seem to find one. Does that mean if the front dial is set to 1 the HW tank will be 35C? Kinda makes 1-4 useless settings for boilers heating hot water as well as CH. Or am I missing something on 30CDi?
For 30Ri then seems to be a wiring centre that includes a tank sensor. But the you also seem to need the clip in timer if you want to specify hw times as well as overriding the temperature. Around £200 for those two! Well OTT.
