Default combi condensing boiler , switch off when not in use?

currently i'm only using it for hot water on demand, so its not doing
a thing when i'm out at work.

however the central heating temperature setting is still on 70 or so
degrees. does this mean its having to keep some water heated this hot
in case the heating is switched off? or does it not do anything until
the heating is switched on?

just wondering whether its worth switching the boiler off when im
out? i do sometimes notice it starting up when im not using any water
and the heatings off.. wonder if im wasting any gas.

Which setting is on 70 - is this a setting on the boiler - or on a room
thermostat?

As you mention "on demand" I presume it is a Combi - but if you can provide
a make and model then the experts will be able to give a precise answer.
Does it have a timer? Do you have a hot water cylinder?

It says COMBI in the subject line.

hi its a glowworm flexicom 30cx

boiler setting to control central heating temp is on 72 c, water is on
50 c but i can change these.

no room thermostat, just a basic timer to switch the boiler on for
heating.

no hot water cylinder.

First job is to install (at least one) programmable room thermostat
(Chronogyr was the last I bought, but that was a while ago). It's an
easy install, and they're not too expensive, relative to fuel bills.
They're a far better means of controlling domestic heating than a
crude timer.

Probably a sub-standard installation with no room thermostat (but that's
another thread).

Does the user manual give any hints any hints buzz words a

"eco mode", hot/warm standby?

Whe you come in how long does the HW take to come through to the tap and
settle down to a steady temperature. If more than 15s you can probably
assume that any 'hot standby' feature is turned off.

If the Central Heating is not switched on (due to manual selection or room
thermostat) then it shouldn't matter that the boiler is set to 70.

As there is no storage (internal or external) - then I am surprised that the
boiler fires when not in use. DHW is sensed with a flow sensor (not a temp
sensor as in my boiler)

Sorry - - can't help but will watch with interest.

And if the boiler is like mine it shows two lights when it is heating
water but only one when it is on at either HW only or HW and CH but
not heating water and none when it is switched off completely.
