Houses that have fitted an electric shower but retained a stored HW tank are likely to use less of it, likewise with cold-fill and/or low-water usage washing machines and washdishers.

Not flowing away quickly enough appears to be the problem

[Doctor Drivel]

Many have the DHW temp on combis on max. It is best to set it around

50-52C. Less scaling in the combi's plate.

[Doctor Drivel]

I have known stores (well the heat bank version) to run at 60C, The plate heat exchangers are very efficient. The larger the plate the more heat extracted and efficiency rises meaning lower store temps.

[Doctor Drivel]

Many combies can be set to 62C DHW - ATAG comes to mind. They preset to

52C. It is best to set the DHW at the combi to what is suitable. Then every few months turn the combi to max DHW and run that through the taps for a few mins, then back to the your comfortable setting. 90% plus of Legionella dies at over 60C.

It may have been illegal to build new houses with such a waste, but there are millions of house built before the ban with discharge into an (outside) open drain.

My sister lives in such a house and it's (at most) 50 years old

Mine does, it goes into the sewer system. Its quite common in the midlands. The house is 31 years old.

Why don't you let your prejudices show, Bill?
