Certainly, I’m quite keen to know. We paid a lot for this fire…

Ours is the “g20” natural gas

And there in lies my confusion. Even if you take the lower input value, of 8.7kw… the output of 7.5kw, isn’t 94% of that. So how can this be advertised as a 94% efficient fire? 94% of what?

I wonder which the fire manufacturers quote. Lower “looks” better I guess

Nice, so the higher of the two is what we see at the meter right?

There is an adjustment for that. They’re sending some one from DRU to come take a look. Will see what they say.

Yes fair comment, the installer came back today to have a look, he did point out that those vents in the faux chimney breast are pumping out a serious amount of heat that you wouldn't really get on a conventional flu. He is right to be fair, but i wonder if that bumps up the efficiency on the...

So this was an error, the input for this fire is not 7.8kw. Someone from the shop had written 7.8kw on the install sheet, but when you look at the manual it does clearly say 8.7 kw input (Hi) 9.7kw input (HS).... What is the difference between Hi & HS? Either way, atleast we know now atleast...

So ran it for 3hrs tonight, checked the meter on the hour, every hour, the fire if nothing else is consistent. But the figure has thrown another layer of confusion. It was using, on the nose, 0.84 m3 per hour. Which would be somewhere in the region of 9.0-9.4 kw per hour. Though on the manual...

Listen about 10-15 secs in, there's a distinct knocking / dripping noise and im not sure what that is. May need the volume up a bit.

Thanks John, was a cold night last night so had chance to try it again, tried both setting 6 and setting 5, both verrry similar outcome. :- All the radiators except rad 14 got hot, that one stayed cold for about 30-45 mins. It did get hot after about an hour or so though, long after all the...

The northwest is a cold place. I’ll run it for a couple hrs tonight and get my calculator out it’s 7.8kw input so that should be easy to work backwards from.

Great shout, but alas. No. On an old U16 meter.

Sign off sheet Also found this stuff in the manual, based on eyeballing it id say we have about 1.8-2M of vertical, 0.5M of horizontal, and 2 bends (the first being easily 1M above the unit). So I guess reassuringly puts us miles away from the non-permissible area. and lands us in Scenario...

I’ll dig out the install sign off sheet when I get back. When they installed they checked that only a month ago.

I’ve mentioned the low power to them once already they essentially dismissed it. So wanted a few opinions before I went back

Thanks. On the install sheet, that’s showing as a pass… with 20mbar. Is it an issue that the flue has two 90’ degree bends ?

Hi all, We've had a Dru Global 100 Gas fire fitted in an extension recently, we had it on for the first time properly last night (we were told to let the plaster dry on the newly made chimney breast for a few weeks before using the fire). Spec :- Dru Global 100 BF Issue is the we had the fire...

Oh and I totally forgot, to add a bit of context, i've done a little map of how the rads are piped up (birds eye view) starts at 28mm for the first meter or so, then splits into 2 x parallel runs of 22mm, then down to 15mm to each radiator, for the last meter or so. On setting 4, it was rad...

Alriiiight, so revisiting this one as back in the property now and have had time to test it. So I decided to take the methodical approach and just up the setting by one. 3 was default, (constant pressure 250mbar). I set it to option 4, (constant pressure 300mbar). Results below. :- Radiators...
