Combi-boiler or stored?



Alpha say: "When the store is fully charged an equivalent domestic hot water output of 50kW gives a flow rate of 18 litres per minute at 60C, enough to fill an average bath in about 3.5 minutes.
If the store did run out 11 litres/min will still top the bath up. So, an average bath can be filled quicko. Showers will be high pressure.

That's if you have seen large flowrate combi. This man is wanting info to make a decision on a water system for his home. For his situation and needs the Alpha and Greenstar 40kW are ideal.
You acting the goat doesn't help at all.

This is bullshit marketing like music power on amplifiers.
It is not an equivalent power output of 50kW because it lasts for a short time.
Plugging the numbers in, the boiler will deliver 90 litres of water, mixed with cold at bath temperature. It will take longer than 3.5 minutes to do it as well.
After that, the remaining 60 litres of water needed for the bath will be at 11lpm.

They are completely different products.
The Greenstar could be considered to be "high" flow rate if you consider 16lpm at 40 degrees to be high flow rate. A storage system can outperform that in every way.
The Alpha has a tiny store and a standard sized burner and is very limited as a result. The marketing information that you have read is not borne out in the technical specs.

The standard answer from a fool regardless of the question or requirements.

Of course. You can only cope with simple installations. Hence the one answer to everything.

You got shares in them or something... how many time is that so far this thread? OK we hear you, you like the Alpha. To quote one of your erstwhile favourite phrases "(Other) high performance combis are available"
