heating the house

Bendy_House

The success of the leccy heater in THIS case does look to be significant, tho'; it's only a 1.2kW jobbie, and this did a much better job than BOTH of Agu's CH rads. 

So, something is very amiss. 

I hope Agu will report back to confirm how hot these rads gets, and it would also help to know their sizes.

If they clearly 'work' - become 'ouch' hot - then I'd suggest that Agu turns their TRVs up to max (5), and brings the Salus in to that room, and set it at, say, 20oC. See how that goes.

Have you ever bled the air out the rads? Or its cold from being blocked up, not balanced.

Bendy_House I will do the tests and checks tomorrow radiators are hot when they are on the highest, they are . thermostat is programmed for different temperatures during the day and weekend. it shows temperature i will report back tomorrow I moved in to a house with a crap boiler which died after 2 months . I dont remember house being hot back then , I think it was the same. I think its narrow pipes , or all heat comes out through the walls . I bled radiators all are getting hot equally the same . bedroom radiators are the old flat type (upstairs and they do get properly hot) downstairs has the new kind of radiators if I set up radiator in the living room to the highest and set the temp to go to 20 deg , in winter thats not gonna happen it will go up to 19, maybe 20 well after all day . if I ignore thermostat and just switch on boiler to heat it will go to that temperature but it wont be quick, quicker

I will give you all the info but the real question still is- is it good idea to open other radiators while having heating on in the bedroom at night, or not?

Is your house detached, semi- or terrace? When was it built?

But, to answer your question directly, I would set the TRVs on them to 1 (~10C) , 2(~15C) or somewhere in between as you don't need those other rooms to be heated to the same level as your bedroom whilst you are not using them..

its a semi, looks like a bungalow and its from late 60s

is it gonna cost (much )more having extra radiators at the same time as the bedroom one which is on?

I literally cant afford bills since these went up by milion times ,thats why Im asking

The more rooms you heat, and the higher the temperature you heat them to, the more it will cost.

Agusya, any room you do not use, don't heat it. Why? 'Cos it's a waste.

Instead, window on 'vent', curtains open (for even minor solar gain), TRV on frost (to protect pipes from freezing - which is unlikely anyway), and keep the internal door to it shut (to prevent moist warm air from the rest of the house going in and condensing).

If you want a warmish bathroom - and who doesn't - then have the TRV in there (if it has one?) on 2 or 3. Perhaps turn it up when you are going to have showers, for example.

Hallway - if you don't need it warm, then don't heat it. Perhaps good to have it not chilly, tho' - say 2 on the TRV?

Living areas, have it at whatever temp you require. Do this by opening the sitting room TRVs to max (5) and bring the 'stat in there. Sit it at roughly half wall height, away from rads and draughts and stuff. Set the temp to what you 'need'. Unless you are elderly or infirm, I'd suggest trying to set it to 18oC, as you can usually get cosy at this temp with a snugly blanket.

If you need/want it warmer, bear in mind it's going to cost a lot more. The higher the inside temp, the greater the heat loss. So a lot more will be heading out through the walls, windows and ceilings. And, of course, if you leave your sitting room door open for your cat, you will lose a LOT of heat, so that's your call.

Imo, that's what to do with 'temps'. 

A different issue is why a 1.2kW leccy radiator can seemingly heat your sitting room, whereas two gas rads cannot. That just doesn't make any sense. I'd like you to understand that there must be a good reason for this, and not to jump to conclusions such as 'leccy is better', because it ain't. And it's a LOT more expensive.

I could speculate all day - eg you turned the leccy heater on to 'help' the gas rads. Or the TRVs were set too low. Whatevs. There IS a reason, and it isn't that leccy is best.

So:
Rads at 'frost' in all unused rooms.
Windows on 'vent' in all ditto.
Doors shut to all ditto.
Bathroom rad at whatever setting you want, but ideally not when not in use - waste.
Hallway on '2' so as not to be cold, just cool.
Sitting room TRVs on 'max', and room stat in that room. Set it to what you want/need.

We aren't just trying to save energy because of its cost, but - little exaggeration - for democracy. It's still good, even tho' folk can, and have, abused it.

How is the loft insulation? 
As it is a 60s build can we assume that it has cavity walls? Do those have cavity insulation? Where are you & what is the eXposure like (in certain wet/exposed areas e.g. the west coast, cavity wall insulation may not be a good idea - in fact it can make things worse)?

The reason that I suggest having the heating on low is to avoid the potential for interstitial damp building up in the walls (plus the bigger temperature differential between your heated room(s) & unheated the more that heat will bleed out  from heated to unheated rooms).

I am with B_H on that there is something afoot with your heating system, whether there is some kind of fault or it & it's controls are not being used properly.
