The Takagi condensing multi-points, not available in the UK (yet) are
"very" efficient, and can return around 38 litres/min.

They also developed multi-points that can be installed outside to save space too.

- Your claim that it delivers 38lpm is only under the best possible
conditions. This is equivalent to 10 U.S. gallons/min, and from the
graph, this is only achieved for water temperature of 60F (15.5C) in
and 95F (35C) out (hardly hot water is it?) or 70F (21C) in and 105F (
41C) out (tepid). If you look at the rate for a more realistic
figure using the UK defacto standard of dT=35C (8C to 43C) (46F to
109F)then the output is at around 6 US gpm or 23lpm which is not
impressive at all.

You need to look at figures again.

We all have, its crap Dr Combi. Provide the figures that show you
can have a hot bath, preferably a nice pre 1980's one filled at 38
litres a minute with water raised by delta T 35 deg C.

Until then your seedy little Combi lies have been revealed to all the
world.

Just for reference my cold water supply to the bath just measured 16
deg C at 20 litres a minute. The hot water from my "airing cupboard
filling hot water cylinder" filled by a gas guzzling, silicon coated
90.9% SEDBUK boiler (singular) last fired four hours ago is at 65 deg
C filling the bath at 20 litres a minute.

As for mounting a multi point "outside" then on your third world
shanty town estate then that might be acceptable - but won't it get
nicked by the local corgi registered fitter because its better than
anything else in the world - ever?
