Apologies I posted this in wrong forum:

I have an open fire in my living room which I do not ever light. I have gas central heating but there is a breeze down chimney and heat escaping up. I was going to buy something like

and leave it in front of fire in the hope it would emit heat out towards the room and partially block heat escaping heat. I would like opinions. i am not very efficient in DIY sort of things and also considered the chimney balloon but with a postal strike in UK there may be delay
 
You need to block your chimney with insulating fiberglass wool,that will stop the breeze and prevent heat escaping,
 
I just installed a chimney baloon - seems to work ok.

From thw wording of your post it sounds like you plan to still light the gas fire when your chimney is blocked off.

I'm no expert, but that sounds very silly/dangerous to me.

Heat is always going to escape up a chimney when a fire of any type is lit. If you plan to install a balloon then I'm guessing you couldn't light a fire after it.

No it is an electric fire at link supplied

I know. Maybe I did not make it clear. I was thinking of placing the electric fire in front of the fireplace to heat room and stop some heat escaping.

The baloon was an alternative consideration

Thanks for replies guys
 
Can't see how the fire will block warm air going up chimney due to draught.

I use a black bin bag full of fibreglass stuffed into the chimney, with a small bit of tube at the side to ensure a small airflow to prevent damp build up. Seems to work in terms of cutting down heat loss, hard to quantify.

yeah you are right really

Good idea

As I said I put some bubble wrap around the firplace and it worked but looks bad. Also there is no airflow but the room is much warmer
