Water Cylinder v Thermal Store
One big adavantage of the UVC that we havent mentuioned yet is smaller size and weight 🙂
I'd actually disagree with this - the 200l uvc isn't much smaller than the 277l TS it replaced - and there's other gubbins which comes with it. We've now got three expansion vessels, an exchange unit and a buffer tank crammed into the room where the store used to sit....
LOL scratch that one then 🤣
Think we need a qualified heating engineer to give us the official line on legionella?

I think that I would prefer the opinion of a health professional rather than a heating engineer.
Lol, Im one of those and I havent got a clue! Just been scanning the web and opinions vary from one per day in industrial settings and once per week in domestic, to that the risk is so low in sealed systems as to be virtually zero. Still regulations are regulations and I thought a heating engineer might be able to shed some light on those🙂

Alternatively if an electrical engineer could shed some light on it, then it could be around 265nm and neatly disassemble the DNA of any lurking legionella 😉
Save energy... recycle electrons!
I actually have a UV lamp in my header tank, it stops the formation of "The blob" nicely 🤣

Hi @bontwoody
From the information that I have seen, to some extent it depends upon how much hot water that you use, the bacteria is much happier fornicating in a warm tranquil environment. Most heat pump manufacturers appear to suggest raising the temperature to 60C, for at least 10 minutes, once per week.
To help save energy and reduce the cost, you could consider installing a solar PV system and electrical power diverter, which could be used to heat the water to 60C or above, most days from Spring through to Autumn. We have such a system and I swear that I can hear the bacteria screaming as they are being cooked. 😎
That was the way I was thinking too, but I think your descriptive language trumps mine. I can hear their plantive howls as I type 🤣
