Then I decided to use the MyEnergi eddi device to control the hot water tank.

PV feeding an immersion made financial sense when exports were "deemed" (e.g. 50% of generated under the old FIT arrangement), but now I think many people are on an smart export guarantee tariff, so every unit not exported means a reduction in income - it effect it costs about 15p/kWh to heat water that way (compared with maybe 6p ish to do it by gas (depending on boiler efficiency etc)). Environmentally it's swings and roundabouts of course, but quite likely your kWh might be better spend displacing a kWh of gas fired electricity generation (at perhaps 60% efficiency)  than gas fired local hot water generation (at perhaps 90% efficiency). Depends on your gas boiler of course - if yours still has a pilot light, I guess it's not in the efficient condensing category...

Another approach (which I've got) - is to have solar thermal panels in tandem with PVs (if you've got the roof space of course) - simple thermal panels get many more kW out of a sq m of roof than PVs, even if it's only "low grade" energy as warm water, it's perfectly useful for heating (even pre-heating) a stored hot water system. In my case it feeds a thermal store that provides space heating as well as domestic hot water - so the thermal panels make a contribution to the underfloor heating in winter too.

It surprised me - I expected more fluoridation but the report shows that relative wealth has more to do with good teeth than water supplier

Hello Chris:

There is an old joke in the Orlando theme parks that you can always identify a Brit by their white legs and bad teeth!

So would I. I see that none is added to my supply.

Toothpaste is full of fluoride, but I suppose that does not help if you cannot be bothered.

The other great threat to teeth is (cigarette) smoking. Vaping does not help either. Nicotine reduces blood flow in the gums.

Any road, my teeth are sound and my legs are lightly tanned - at least between my socks and the hem of my shorts.

Perfect-looking teeth aren't always healthy. I'm happy to demonstrate they are still there, few fillings, and all my own, and unaffected by the application of braces etc

We also can't trust that tanned legs are because of time spent in the sun either, given the many products that permit us to apply appropriate shades of colour (including orange if we so desire) to give a false outward appearance of our health (or lack of it).

Both of which go to show that maybe the stage-managed glitz has spread beyond the silver screen and theme parts and is now out in the wild ?

Not for me, and if that means I'm a 'Brit' then so be it !

You must have gone "private" for your dental services (such as cleaning) if you still live in the UK.

Why? I know there have been problems in some areas of the UK, but all of my family use an NHS dentist no problem ... there are small charges for certain procedures (although these are waived for children and eligible adults).

Having worked all over the world, I never wanted to move anywhere else for a number of reasons. I'm equally happy for ex-pats to tell me they are enjoying their life ... it doesn't mean I would have the same experience, though.

There was a recent news item (May 29, 2024) that stated that the NHS has only 42.3 dentists per 100,000.

It didn't say however, what the waiting time for dental service was.

Where one lives or works for that matter, is a purely personal decision and if you are happy with your life, that is very positive.

AFAIK, the problem is getting registered as a new patient. I have had a look at the NHS search facility for my area: some are simply not accepting new NHS patients, some accept limited categories, e.g. children, some accept on the basis of availability.

I assume that dentists are obliged to continue to provide services to existing patients.

Dentists were always more sensible than doctors. If I could find a private GP locally, I would go there.

My practice has recently put up a sign saying, "New patients welcome". I really have tried very hard not to add with a felt pen, "but what about the existing ones?"

Agreed. I think I could settle in France, but there is always the risk that the grass only appears to be greener.

oddly I do live in the UK, and like it, but  I will say dentistry is very variable. Twice now, once in Essex and once in Hampshire, I have been told that my current NHS dentist is going private, and I should find another or re-join as a private patient.

In both cases the nearest NHS dentist with space being over 50 miles away, I have reluctantly gone private, and in the second case, when I had children,  there was an offer to keep the children as NHS while still at school, which really meant until 16 ,then the same applied.

There is no obligation, other than reputation, to retain old patients, the decision is purely commercial - private patients clearly pay better. And indeed getting an appointment is now easy, they are seldom unable to fit you in,  just expensive, though I do wonder what is happening to the teeth of those less able to pay.

Being born in Yorkshire I grumble at paying 85 quid each for an inspection and prod about or whatever the next one will be, but having a decent job I can at least afford for all of us to be checked annually. Others I suspect wait for symptoms.

I have not yet reached a state of health where I actually need to know my GP, but I am not convinced that by I am there will be a great deal of support there either.

Considering the no of folk turned away each year applying to study medicine and dentistry, compared to say engineering, part of the answer to me is obvious - not it seems to the politicians.

More medical school places! Hang on, it is already happening (under the last government): https://www.gov.uk/government/news/350-extra-medical-school-places-allocated-in-nhs-training-boost.

One of the other problems is that being a full-time partner in (NHS) general practice is no longer attractive, so there may be more doctors who work a total of fewer hours.

so there may be more doctors who work a total of fewer hours.

Still not seeing the problem in training more folk. -a larger pool of qualified people doing a 4 day week able perhaps with the offer of overtime to come in if there is a crisis. I'm not suggesting lowering the intake standard, but not turning away folk who could.

Rather that 350 extra places it seems like not enough -  just adding a few hundred on what that article suggests is 7500 training places a year is an increase of about 5% - the sort of figure that gets lost in the tides between individual years in other subjects.

Looking at the same thing another way, what is a reasonable  MTTF of a UK GP ?

Apparently the UK has about 38 kGPs in the NHS at the moment and about half as much again working but not in the NHS. Then there are all the other sorts of doctor a medical student may become that are not GPs.

Assuming no career changes  then maybe very roughly one NHS and half a private kGP retires and must be replaced per year.

Retirement ages and lifesyles are changing that and that 1k5  figure is clearly an hopelessly low estimate  as this suggests a job continuity like no other field.  Folk take sabbaticals, move abroad, have families, get ill you name it  so that covers another factor of 2 or 3 probably, and ignoers all the other roles, then that 7k5 medical student figure is not looking overly generous.

I'm not sure that we should expect total career lock-in from a degree choice - no other subjects do - not all folk who do maths degrees in the UK  (comparably about 8000  of them each year apparently) go on to be professional mathematicians, or even maths teachers - you need to train quite a lot more than you need.

Mike.

As regards seeing a GP - After a certain age (maybe 45) everyone needs to see a GP or equivalent)- it is called preventative medicine- every six months. For men that includes a PSA test.

A large proportion of Primary care medical staff here in the US are nurses with advanced medical degrees in selected areas. I had my six monthly check up last week with my female Advanced Primary nurse. It has been shown from research that women are better than men as they listen to their patients with more "eye to eye" contact time.

I would't even attempt to explain the US Medical systems, as it is so different from yours.
