central heating ?

[the snooper]

Its a neutral area and the best compromise for a decent temp, (all Yorkshireman jokes aside) my hall stat is 17deg, this is a nice temp in the living and dining rooms and the bedrooms are controlled with TRV's the towel rad in the bathroom is just on lockshields and stays on all the time

years ago we had a house that had the room stat in the hallway problem was there was no heating in the hallway no doubt some brainless clown fitted it there

I -cant realy see the point in a room stat when u have thermostatics on the rads. u have the temperature control on boiler as well

It's for overall control if the system

Room stat is air temp
Boiler stat is flow temp, so how hot the rads get

it don't matter as long as the boilers up quite high and rads get hot enough .there on -trv as long as boiler is set to over 60 c the cylinder stat is controlling water temp

In a basic sense, no it doesn't, but to get maximum efficiency you need the correct drop from flow to return

Its an 11deg drop on a std system and 20deg on a condensing one, all the heat loss calcs are based on this, as well as the 21deg rise but with -1deg outside temp, hence stats being set to 20 from the year dot

you would need 1 rad open full all the time to allow pump flow if all the other trv's closed

the -bathroom towel rad sorts that out it hasn't one

terrible waste of gas though as it would run full bore until boiler water temp reached its limit, all other rads would have probably clicked off well before

but the bathroom rad can also have indirect results if its not equaled out correctly on the rad system

not really it stops the water boiling in the system at the boiler hence why one radiator is left with lock shield valves on instead of thermo valves

-I'm a greedy gi.t heatings on timed as were out all day so its on for an hour before work then off till 4 pm then on till 10 pm
and only over ridden if in all day and all doors open

tell our lass-that if u dare better u than me. best laugh I saw-at work was some sparky put the thermostat above a radiator-. heat came on -thermostat turned it off and so it went onwhat a prick took me-2 minutes to guess it

been there all i got was im cold sat here in a tshirt vest and a skirt or leggings i just said go put a jumper on and get dressed but oh no never heard the end of it for that

yes i know that but its still a waste of gas when a room stat would have switched the boiler off instead of allowing the bathroom to heat to the point that you could cook a joint of meat in there

Modern boiler will modulate and use less gas

Most females have no understanding of the way central heating works with thermostatic radiator valves .
After you've set it all up they'll make some adjustments then tell you it's still not working .

Seconded. Every one I have met considers a thermostat of any sort to be just a fancy on/off switch. I tried and tried to educate 'indoors, but failed. So I have just restricted the TRVs now which makes her content that they are "on", even though they are still regulating.
