Chav, you really are a dumbo. Here is the GasTec report:

Chump, gullible could have been a word made for you...

Look at the hot water draw off pattern they used for testing. Lots of
unrealistically small 1.8l bursts that could be satisfied from the
stored water. For many instalations you will use 1.8l just running off
the dead leg. 24l for a shower - great if you only want 2 mins in there
- but remember some folks might actually want to get clean. What about
baths - even your mythical 100L bath will make a big dent in those
figures. They also seem to be assuming that a 30kW combi will be running
at that power output into the CH for three hours a day in order to have
enough captured waste heat in the first place.

Not exactly a realistic scenario is it. Still realism was never your
strong point was it.


It's amazing what a manufacturer can achieve by paying for a test
report.


Matt, yep, an objective report. Amazing isn't it.
