Hi,
I was looking at the SEDBUK website
W.
If it's in the database it's because they submitted the data!
It's on their web site now. It's a shame their sales team don't know about it!

The Greenstar and HighFlow are two separate models. SEDBUK got the name wrong.
No. There is a new model - see
It has a condensate pump, so it can be sited where a drain is not present.
This is a 29kW model with internal heat bank for which they don't seem to specify the size. It may do 20lpm to begin with, but not when the heatbank is exhausted.

From the diagrams it looks very similar to the old HF 400 series. However the marketing blurb goes on and on about the condensing feature and hardly mentions the heatbank. I guess the heatbank is the same size as the old boiler but they may have reduced its size to accomodate the extra components.

It then drops to 11 litres/min. Two stage. Never runs out of hot water. It will recover within minutes.
Right. The point being that their 20lpm claim is stretching reality a little.

No. It will do 20 litres/min and fill an average bath up at that rate before dropping down to 11 l/min.
You don't know that because they don't specify the size of the heatbank.
There are a number of additional components crammed in there vs. the older product.

These types of combi's are designed to fill one bath pronto and a have a v quick recovery in a matter of minutes after.
Mmmm. We've had that discussion before and I don't see any point in repeating it.

Exactly. You haven't a clue.
I am sure that discerning readers looking at previous threads will be able to realise the limitations of this approach and decide for themselves whether it affects them.

What limitations? I'll answer for you. There are no limitations. For a one bathroom home these are the business.
Can we presume that was a typo and you meant "condensing" rather than "combi's (sic)".

They are certainly a useful option for single bathroom homes and a considerable improvement on a typical instantaneous combi. However, they are not a panacea for all water heating problems.
They are have limitations. All products do. It is a case of matching the limitations to acceptable parameters for the specific problems being addressed.
