Default Several things wrong with new flat - no central heating, low hot water pressure even with water pump, noisey pump

Hello
I've just bought my first flat and wanted to ask several things that
I'm not familiar at all - i did buy some DIY books but afraid to do any
of the work at the moment before i know for sure what I'm doing is ok
and not going to cause any permanent damage - also wanted to ask you
experienced guys before i pay a plumber

question 1) We have a boiler, hot water tank, water pump (next to the
boiler), what looks like a valve next to the water pump and a shower
pump

Now my understanding was the water pump gets used to circulate hot
water around the house for central heating, correct?

Well we have no central heating! the only heating we have is a heater
in the bathroom (both main and ensuite) but i was told they may be
connected differently to the radiators and hence why they work. But
even they stop going hot after sometime.

So no central heating - so after reading the DIY books i have, i
checked:
a) the boiler - which comes on when i switch everything on and i can
see the pilot light and i DO get ho****er so that looks ok

b) the water pump - it has 2 settings, high pressure and low pressure.
i think the pump is working but i cant tell for sure since when i touch
it, because its next to the boiler, the vibration is THERE but i cant
tell if its from the boiler or the pump. anyhow, if i change the
settings to low pressure, the water pump seems to quiet down in
vibration a bit so i think its working.

c) valve - i havent checked yet and read that there may be a switch
that only enables HW only and no CH - this could be the cause which i
will check tonight

d) raditors themselves - haven't checked but the pipes to the radiators
itself is cold so i think no water is coming in.

So afterall of the above, i can only think it is either the water pump
or valve.

The boiler does have a timer and a separate 7 day heat immersion timer
(presumbely for CH only?) - both constantly set to ON.

Question 2) In the ensuite - the shower pressure is ok - since that is
coming from the SHOWER PUMP in the airing cupboard and i can hear the
pump working when i turn on the cold tap and hot tap on the basin sink
in the en-suite.

However, in the MAIN bathroom, the cold water tap pressure is LOW - and
i can not hear the pump. its only when i turn the hot water tap on, the
pump seems to kick in and pressure is ok.

Same when i use the taps/shower in the bath of MAIN bathroom

so it looks like the pump is only coming on for HOT water ONLY in the
main bathroom - why is this?

Also, when people talk about shower pump, i thought it only boosts the
shower - but in ou flat, it does for taps as well - is this ok?

question 3)
Shower pump (showermate 1.4bar twin max - working pressure 3.5bar) is
way too noisey in the airing cupboard.

how can i reduce this noise? i read that i can have a box and some
insulating stuff around it - but also read this is not good because the
pump may overheat?

the pump is just sitting on a shelf inside the airing cupboard

----

Sorry for all these questions - but i'm just worried about all this -
and we still need to sort out the rest of the house

details:

boiler - Label says - myson heating, Apollo Fanfare 15/30, 30/50 and
40Si. it has this old looking timer program underneath it which only
has a clock, settins for CONSTANT, OFF and Timer.

Another programmer that is wired into the clock timer above - label
says "Kingshield 7 day immersion heater timer T23B0H" - but no manual
etc so i cant program it - and i;m not even sure if it is doing
anything - it is on.

Hot water cylinder also has thermostat - which i have it set to 70??

thanks
