now i am able to heat my home again, even if it is with a crap make of
boiler (ravenheat) i want to get it all set up properly.

firstly i want to put in a couple of TRV's, so will drain the system, change
a few valves, then re-fill, the plumbers didnt add any inhibitor or owt when
they fitted the new boiler, so i guess i'll add some.. what to use i dunno.

i have one room where i want to be able to controll the temp closely, it's
to be my rat room, where i'll keep rescued fancy rats that i am fostering,
so that room will have a good quality TRV on it's rad, but what is a good
quality one?
the other TRV's can be 5 quid specials, unless they can be had cheaper than
that.

once i've done all that, what do i need to do to set the system up so it's
working at it's most efficiant?

i have an infared thermomitor, and i know roughly about the thing to set up
all the rads to have a certian flow and return temp,
isnt there a certian return to the boiler temp to run the system at? or does
leaving the boilers stat at the 'super condensing max economy' mark take
care of that?

How close is "closely"? +/- 0.1C +/-2C (normal sort of mechanical
room stat range). Can the temp be allowed to fall when the door is
opened, if so how long can it take to recover?

Rats are pretty hardy creatures, I'd expect they think they are in
the lap of luxury with a normal TRV. Sick ones I'd have though better
off in a sepeartely heated and controlled incubator sort of box.

You actually set to have a defined temp drop across each radiator the
actual flow/return temperatures are not particulary relevant to
setting of a given radiator.

Read the FAQ section on balancing a wet CH system.

If you intend living there for a while get good quality TRVs like Drayton.
Shop around for best prices. Cheap ones tend to have a short life.

yup i plan to live here for a good few years, neighbour problems or not,

The downstairs is sort of open plan except for the bedroom..... hallway with
a rad on microbore, directly opposite the rad is the archway into the tiny
kitchen with no rad (tho i will add one sometime, got the plumbers to leave
the pipes in place from where the old boiler lived just other side of
kitchen wall, they moved it upstairs, so i can easily add a rad for the
kitchen off the old boiler feed and return that's still in circuit)

then hallway goes round the corner, bog has a door and a rad in there on
15mm, opposite the bog door is the stairs, straight on is the living room
that is 2 rooms knocked into one, no door from hall to living area,
rad just to the side of the old door way on 15mm, and at other end of the
room is a rad on 15mm,

Bedroom is on microbore, if i really felt like it, i could shove some 15mm
from the kitchen rad when i fit it into the bedroom and have that rad off
the microbore, that rad takes a while to heat up, but when it's going it
belts out the heat, and takes a while to cool down, 1970's type rad with
thick metal but no fins on the back.

Then upstairs, the front room which will be the rat room, that has a large
rad in it on 15mm, and it gets bloomin boiling in there even when i turn the
valve right down to a trickle, 1/4 of a turn more and it's off, but the
boiler is the other side of where the rad is, so will be the hottest in the
system i guess.

other upstairs room is my arcade (few fruit machines, pinball, jukebox etc)
rad in there on 15mm has a TRV body, but no head, decorator cap is in place
to manualy regulate the temp,
that's the room the boiler is in, so the boiler adds some heat too, and
again it can get swealtering in there especialy if i leave the door open and
heat is coming up the stairs.

for the rats, dosent have to be close regulation of temp like needed for
reptiles, they handle cold pretty well... they just pile ontop of each
other, and any in the hospital cages will have heat mats.
but it's heat they can't tollerate too well, as they can only regulate their
body temp via their tails (like an elephants ears, pump blood near the
surface to cool it)
so i'd want a TRV head that i can rely on not to let it get too hot in
there,

i guess i can add a overheat alarm to the room, and there's the old vertical
flue terminal from the old boiler that i am thinking of using as a vent,
shove an inline fan in some tumble drier pipe, and run it from the flue pipe
into the room.
