Is it "Summers solstice" ☀️ 🤔

I think this one (Westport) is my favourite course. The view of Croagh Patrick just after you set off...

Anywhere you recommend for dinner tomorrow?

No indeed - they train too hard to be put together with someone so loose at the back.

It absolutely is, and travelling down from Dublin by train was just superb.

He just wants to sit in the cab and toot the horn.

Exactly - you can walk through a graveyard in many a town and tell exactly when vaccination (and antibiotics) reached there.

The "Seamus" who turns up in the 1911 census aged 3 and in the 1921 census aged 4 is a clue that there was some hearbreak in that household...as there was in pretty much every household in that time in the west of Ireland.

He's got 4 days to go to "UK independence day" - it could still come out as he so confidently predicted.

..and if you are still not convinced, have a look at what happens to "babies per woman" rates in a country when that country hosts a war.
It goes up - does that sound like consensual conception?

Whilst we are on the subject, most historical growth in population is driven by "more babies surviving" rather than "more babies".
This doesn't look too dramatic until you notice the vertical scale is a LOG scale.

Once again - the decline in "babies per woman" is indicative of a fall in the rate of non-consensual pregnancy and that is (a) a good thing and (b) not something to be addressed by money

Ah - so this was a part of my "getting off gas" plan. We used to have a gas combi before we started this.
The SunAmp does store heat - which heats water on demand. It just doesn't store the heat in the water.

It charges at a slower rate and stores the charge (so can be linked to solar PV or demand shifted tariffs) - whereas direct hot water tends to need a much higher power and when everyone else is also using it.

Ah - I see from their website that they now do "indirect" cylinder replacements too (off a cold water storage tank)

(This last bit means they are not suitable to be topped up from a back boiler on a fireplace or anything like that)

Disadvantages:
As above mentioned they are really heavy. No way this is going in an attic and it'll take a crew to get it up a staircase so ground floor on the floor is best.
They are more expensive than a standard insulated cylinder.
They are not tolerant of being overheated.

They plumb direct to the mains so don't need a cold water tank nor an expansion vessel.
They don't fade the same way a hot water tank does - the heat is there until it runs out.

Advantages:
There is no water stored in these "tanks" there is no need for a legionella cycle.
There is no "mixing" inefficiency with cold water filling the tank in use.
Their heat loss when not in use is far far less than a standard hot water tank.

When heat is added the phase change material melts and when cold water passes through the circuit it takes heat away from the phase change material which solidifies again. There is a *lot* of heat stored in that phase change.
comment in response to

Inside they contain a couple of circuits of copper tube for the water to go through, a heating element (which can be powered by the mains or solar PV) and a "phase change material" which melts at a specific temperature. There is also insulating material to keep that heat inside the box.

Cool. I might do a thread on the SunAmp heat battery too...
comment in response to
post
If you already have solar panels (or that is in the plan) then a heat battery is a better solution as the extra "oomph" needed to get a heat pump to the heat needed to do a Legionella cycle (60c+) is not easy for a it to achieve. A heat battery needs no such cycle.

Not even in the top 10 stupidest ideas I've heard. The proposed conversion of the old flour depot in the docks to an art gallery has it beaten.
Did anything come of the plan to have a white water rafting experience in the old dock in the IFSC?

It is indeed - each paragraph reads as if it was intended to be in a speech bubble on one of those drawings found in books for the education and delight of young minds.

It makes sense to reuse these power stations for this and for battery storage too as the network connections are already there. It is madness that the Pigeon House* turbine hall is not repurposed as a battery storage but I'm sure there is a reason.
*Actually the power station next to it.

A huge flywheel - in this case 130 tonnes.
It will take from the swings to feed the roundabouts

Part of the UK's success is outside some weirdos on X*, no-one can remember which ones of the England squad have a black grandad and which ones have just summered well, and that tends to feed through to census figures.
*a troubling number of whom are influential in the Tory party.

The mitsubishi single is alsoa lot quieter but also about half the heat output. This unit would have been pushing 9kw here.

I will find out more details no doubt but I fear it is possible that the builder didn't engage a gas safe engineer at all.

This is the multi split on full power in January 2021. The wind is significantly louder than the unit and it was not a windy day.

It's a rural area and the irresponsible party is known.
Percussive feedback is likely.
