Default LPG - Calculating minimum pipe size required to supply a gas fire

Do they quote the efficiency too...?

What size of gas fire is it?! Are you heating the great hall in a castle

or something?

I suspect they've left out the decimal point?


I know, the consumption is quite astonishing isn't it? However, the
maximum heat input is definitely 32 kw; specs. can be viewed at
http://www.stovax.com/images/cms_bro...re_baskets.pdf
(the entry for a large Swan's Nest fire in the table near the bottom of
the document).

I have also spoken to Gazco's technical department, and they confirm
that the figure is correct. (Incidentally, I understand that the heat
input and output are quoted at the same figures for these fires.) The
efficiency rate is between 15% and 25%, depending on the setitng - most
of the heat disappears up the chimney, as with open wood fires. So even
the large fire version may only produce 4.8 kw of heating.

I will actually probably be looking to install the medium sized fire,
which has a (still apalling) maximum input of 21.9 kw. However, my
query mentioned the consumption figure for the large fire as installing
this size is a remote possibility.

I am looking at these fires as they match the existing wood burning
grate. A smaller fire would be lost in the seven foot wide, three foot
deep inset fireplace (it's an early 17th century farmhouse). The high
gas consumption isn't a major concern for reasons which I won't go into
here (but it's not because I'm mega-wealthy!).

Anyway, thanks for the information and the quick replies; I will look
into your suggestions this evening.

Cheers.
