theory is it’s the reason the sea water temperature is rising, all the women of a certain age going for a dook. 

Too true.

And they all park badly.

The other day my wife asked what we’d do for showers if our system stopped working for some reason. I pointed to the newly plumbed in dog bath and electric shower. Has a handy shelf for sitting on and a door and step to get in. 😂 

 

Thinking about it, it'd be easy to buy a lower flow shower head, perhaps a bit like the ones used for electric showers, to use if we had to resort to the backup hot water system.  The shower head we use all the time has a flow rate of around 10.5 litres per minute (I only know this because an annoying building inspector wanted me to measure it, then insisted a flow reducer be fitted - removed as soon as the house was signed off . . . ).  I could probably find one with a much lower flow rate, rather than fit a flow reducer, simply because the flow reducer really reduced the force from the jets.  If I fitted, say, a head with an 8 litre/minute flow rate then we'd get close to 10 minutes of shower time, which is pretty close to normal daily use anyway.

 

This means that a 50 litre heater may well be all we need.  These Heatrae Sadia units look well enough made, stainless steel tank and immersion element, just a simple thermostat for control and all the connections at one end.

The question is whether 50 litres of hot water is OK as an emergency supply.

I think that looks like a good solution. I'm sure 50 litres of hot water is fine as an emergency supply, as 40 minutes recovery time is reasonable. Just read your last post. An aerating shower head would reduce the water use.

We don’t get so many midges our side of the hills even by the Lochs

I've ordered one of the 50L Heatrae Sadia horizontal water heaters, should be here at the end of the week.  Nice that it comes complete with all the bits needed to install it, PRedV, accumulator, tundish, built-in T/PRV etc, although the PRedV is redundant, as I already have a 3 bar one on the supply, plus our well pump cannot exceed about 4.5 bar anyway, given the depth of our well.   If anyone wants a 22mm PRedV they are welcome to it, as I already have one spare sat here.

 

Plan is to fix a doubled up bit of 19mm marine ply to the wall above the door, secured with loads of hefty screws into the studs behind the plasterboard.   Should be fine to then bolt the bracket to this, as the max weight when full is only a tad over 70kg.  Nice thing about this water heater is that it isn't smart, something of a rarity now.  Last thing I want for a standby, emergency hot water system, is something that is too damned clever for its own good.  Quite why anyone would ever feel the need to have a WiFi connected and controlled hot water heater is beyond me.  I just want something simple that will provide some hot water if things go awry.  Last thing I need is to be faffing around with an app in order to just have a shower.

It gives the impression that the customer has some control and can reduce their energy bills.

I blame the marketing departments.
