I assume that the issue is doe to hard water from the borehole - and so limescale buildup, which can quickly kill heating elements.
I look after a few systems with this issue, and have installed water softeners to deal with it. There is some info here.
It gave me a starting point for a terms of reference document for a Green Champions group that I set up at work. That is the only beneficial thing that I can recall.
I have tried to find other uses, but so far nothing else has actually proven up to scratch. I expect that I could have spent more time composing and tweaking prompts and proofreading the output, but it takes as long as writing the damned documents myself.
I have no great desire to be remembered. It is neither here nor there from my point of view. As to how people are likely to remember me, ‘quiet’ and ‘intelligent’ are two words that crop up a lot from people who I interact with casually or occasionally. Those who know be better would probably focus on my environmental and conservation work etc.
Related to that, due to the role that I played in stopping an area being sold for development and instead becoming designated as a nature reserve on one occasion, there is a meadow that is casually called after me by some people that I worked with. I suppose that I would be happy to be remembered as a meadow.
