The air does not 'hold' moisture. Water vapour is just another gas, like nitrogen, oxygen and argon. https://edavies.me.uk/2017/03/vapour/ Now of you are in a room, regardless of the temperature and humidity, the act of you breathing will increase the absolute humidity. This may be masked if the temperature also increases as it is more usual to measure relative humidity. The RH will go down, even if the absolute amount of water is still same. Why this causes physiological problems I don't know. I know I prefer dryer climates: grew up in the Far East and it was horrible, then moved to West Indies to a very dry island, it was lovely. But I do know that when I do a long haul flight, my noise starts to bleed, apparently a known phenomena of the dryer cabin air.

Installation details and PVGIS expected generation, plus electricians sign off just to be safe.

Interesting. Does it actually change the compressor speed, pressure or volume (via a bypass). Or does it adjust the water flow rate out of the ASHP? Or adjust the flow and return temperature?

That will be about 5 kW then. You may get a higher power output if the inlet temperature was very low, and the air very dry.

Have you tried sleeping with boxing gloves on.

Will be this winter now.

Put a barn door in and rent the space out. Got to be worth £600 a month to a desperate Millennium. They need somewhere to stay before going to work in the phone shop.

When I don't understand something that I read. I reread it until I do. But if you still don't understand how something can be switched on and off, without pulling it apart, don't touch a light switch or a tap.

The flap is controlled by a bimetallic strip. Too hot, it closes, too cold, it opens. The output knob just mechanically limits the amour it can open. On the bimetallic strip is a resistance heater that warms up when the E7 (or any power) is applied. This closes the flap and reduces losses when they are not needed (not so brilliant for really early risers like me, but lockout timers can easily sort that, or thick pyjamas). Really simple and elegant solution to a problem. If it fails, the heater still works, just takes longer to heat up as losses to the room are higher.

There is a thin layer on the metal panels. Probably asbestos wool on the really old ones from the 1960s. Did you notice the small element on the the flap control to shut it down when charging?

It is really quite simple. When the storage heater is charging up at night, the flap is automatically closed. When it stops charging up, it opens to the pre set position. The reason this works is because a storage heater is a convection heater i.e. air passes through it. All the flap does is limit, or stop the airflow. Now don't tell me you cannot understand that.

Well gas is about 10p/kWh. So divide the cost of your battery system by 10 (it should last ten years. Then by 5 assuming you need 5 kWh/day out of it. Then divide by the number is of days you want to use it, say 200 a year. Then add the cost of charging, multiplied by 1.3 to the number. If that is less than the gas price, plug in a fan heater. If not, use the gas.

Is that the fetish club you are still allowed into?

Then do as you want to and elicit a challenge the DNO to prove you wrong. Just don't come crying when they tell you to disconnect, and possibly fine you. If you want to play the game, stick to the rules. And wen they are full at about 10 AM in June you are then in effect getting nothing. Fair enough, but I would like to get something for my efforts.

Twice the energy, in the same time, for the same area. Or twice the power for the same area (power is J/s). With heat transfer, area is important. Storage heaters take advantage of this by opening the flap and allowing more air to pass by. This is the same as increasing the area.

Simply, yes, it is in the numbers. Feolite has a SHC 0.92 kJ.kg-1.K-1, k 2.1 W.m-1.K-1 and rho 3900 kg.m-3 Clay brick has a SHC of 0.8 kJ.kg-1.K-1, k of 1.3 W.m-1.K-1 and a rho of 1700 kg.m-3 Thermal Inertia is calculated from the square root of the product of the above three Feolite is 87 kJ.m-2.K-1.s-0.5 Brick is 42 kJ.m-2.K-1.s-0.5 So basically, in the same amount of time, and at the same temperature differences, for the same exposed surface area, Feolite can release (or absorb) twice the amount of energy as ordinary clay brick. But it has a mass of over twice that of clay brick. So building a a house of out Feolite would not really make it more thermally stable, just heavier. The reason it is used is it takes up less space. Doing the same for pine and you get 371 kJ.m-2.K-1.s-0.5 around 6 times the energy released. Why the term 'thermal mass' is a nonsense term. Though you would not want to stick an electrical element into a block of pine and heat it up. Material properties from here: https://material-properties.org/

On very large military projects, the competing companies are often paid to produce designs and costings, and sometimes prototypes. Which reminds me, I must go and look at that new stealth, the B-21.

Stayed in a place on the left bank, no A/C, was 34°C at 2 AM. That was cheap. But got to see the end of Le Tour nice and early. Still got my Le Tour cap. Pedro Delgardo won, well his chemists won really.

I put mine up in a cheap hotel. That stopped them visiting.

My boss has strange accounting ideas. When we have to throw stuff away (a legal requirement) he prices it at the retail cost, not the wholesale costs. VAT to him is a turnover tax, not a tax on profit (he still thinks we are on the old 12% scheme). Luckily, in the words (almost) of Joe Walsh, "have accountants to take care of it all"

Just put in one, larger shower, large enough to squeeze two bodies into. Been years since I have had someone scrub my back, one disadvantage of living alone.

I don't think you understand business accounting very well.
