Way I see it most houses , have legoinella bugs floating around some where ( maybe ?)

Off course not; a legionella victim needs either a doctor or a corroner to check him out, not a plumber.Been in the trade for 35 years & NEVER come across this...
According to my information from ACS training, fully pumped became the standard about half a century ago.most open vented cylinders were heated via gravity fed primaries where water was heated to a minimum of 70K with hot water being drawn off every day.
Probably do, but is irrelevant. Legionella only becomes a threat above certain levels apparently.Way I see it most houses , have legoinella bugs floating around some where ( maybe ?)

Legionaires disease numbers are verifiable to anyone who cares to look at ONS archives.

Apart from that, to heat gravity fed cylinder to remain above 65C, the boilerstat would have to be on or very near max. Any RGI worth his keep has the experienced most boilerstats NOT to be at max.
Never looked into the details about those temperatures, but at a guess I'd say that both 65K and 75K will kill legionalla stone dead in seconds.
Something tells me that you are trying to be a bit too clever with the figures you quoted.
Subcontracting for CALIBRATING boiler stats on council stock???? First time I ever heard of council spending money on that. In fact, I've never heard of open vent boiler stats being calibrated period.I used to calibrate boiler stats when sub contracting for Islington council (1980)
You are miles off. Like I said: you are trying to be a bit too clever.Ideal temp for legionella bacterium is about 37K , below 20K & above 55K the bacterium is dormant
I am pretty sure that below 55K legionella is stone dead, and certainly below 20K.I stand by my figures regards legionella , i don't have to be cleaver , & your figures are?

But even if, since when is social housing heating work known for it's great standards? Did a brief stint assesing in social housing, and I don't think a day went buy where I didn't cut somebody off due to immediately dangerous situation.

So the statement was correct then, a combi is better for a shower, not as good for filling a bath.If you insist.....I have a 37cdi which gives a great shower, for as long as I want. However, it is slower than the old OV cylinder at filling my bath.
Still waiting ben....
( Decent ) combi will fill a bath just as surely as a cylinder, just a bit slower. Bearing in mind that nobody in his right mind is standing next to the batch waiting til it's full whilst twiddling his thumbs, it makes no difference whether it takes 4 or 8 minutes.
What combi offers that ov cylinder doesn't is:
2nd, 3rd and 4th bath even if you forget turning the timer on.
Legionella-free water; contaminated cylinder water used to be #1 source of legionaires disease when we still all had open vents.
I am pretty sure that below 55K legionella is stone dead, and certainly below 20K.
