Hi PE
Our fire is a Burley G4240 - 49 Model Environ. Heat input (nett) High 2.5kw. Low 1.5kw at somewhere between 90 to 100% efficiency
With the required vent, and because we don't have a flue we really do not have any draughts to speak of. With the lounge door open and upstairs doors and windows open you can feel a draught. However obviously during cold spells when the fire is on we do not allow those conditions to prevail.
I do not know if Burley still make this model. All I can say is we are delighted with its 4 years trouble free performance, and I have the comfort of knowing that I installed it, as a Corgi registered installer. Now retired.
Thanks for that snugib
Where abouts on the wall did you install your vent - up high or down low? Any links to any suitable type of vents - I haven't a clue about these and need to show the wife how things will look ideally before going down this road!
