Any chance it is just getting hot. Stopping for a minute or two while dealing with the faulty firings may be enough to cool it a little. Or it could be the nails, have a good look at the next batch.

Not talking alcohol induced, more running around a 40°C commercial kitchen for 6 hours. Trust me, you sleep after that.

Can you design the house so that the ES is, initially, separate from the bedroom. But in the future a new doorway can could be fitted to connect the two. Or do what I do, work before bedtime, then I am a little dehydrated for the night, and tired. I sleep quite well because of this. Mornings I get up early, tea and fags for an hour or two, then shower/bath. No one is disturbed. Living alone is the real answer.

That will be the glass ceiling then, well until it is shattered.

@JSHarris I was actually thinking that these could do the donkey work and something very low powered would sit on desk. It seems a shame to have loads of low power, but powerful computing and just run a simple task or two on them.

What is the standard deviation, i.e. does it happen a few times in a row, begining of nailing, towards end of nailing session, or apparently randomly.

As most if these small, but powerful, computers probably have a spare bit of capacity, how well would they work with thin clients (term may have changed now to Cloud something or other). Be a lot less clutter on my desk to have just a monitor and keyboard. Easy to move too.

That is about a third of what my whole house used yesterday.

You should at least know how much DHW energy us needed. Wind direction and speed have a big affect on performance. Strong South Westerlies are warm, week Easterlies and Northern winds are cold, and in winter there is little solar gain to be had in the 6 or 7 hours of daylight.

You can always fit PV at a later date, though it need not cost more than a tiled roof. Again, parts can be self-sourced. 300 m² is a big place, about 6 times the size of mine. So without a lot of insulation under the UFH and perimeter, you stand to loose a lot of energy. Is it realy any cheaper to fit radiators upstairs, rather than UFH into the floor? You can use a different spacing for the pipes to limit the energy transfer. Have you done the heat loss calculations and DHW usage yet?

Going to be hard to gauge the effectiveness of any ASHP over the late spring and summer months. Do you collect external weather data?

02/09/2019 09:03, 17.125°C Full day off as well. Bikini weather.

May be worth improving the walls with some extra insulation it it is possible.

Is that total emissions (absolute), or CO2/kWh emissions (relative).

Are those building codes really any better than basic building regs?

Yes, I hate using my phone. The screen is never big enough, or too big.

Not sure how no increase in temperature can shorten then heating time from the AEHR. If the equipment needs cooling, cool it with a fan, don't over complicate it. Energy scavenging is not really worth the effort. https://www.newscientist.com/article/2186721-green-car-tyres-can-generate-energy-while-monitoring-road-conditions/

It goes back to the old story about the Cornishmen that were really cold. So they sat around a candle to warm up. One asked what they would do if they got really really cold. To which the reply was. 'Light the candle'.

Yes. You can work it out, find the volume of the cupboard, multiple by the density of air, work out how many joules is being pumped into it and you will end up with the rise in temperature.

Sounds like this is heading for prorogation.

Any Carrier unit. Many are rebranded. Also the Japanese ones are good. I keep banging on about this, but look at CO2 ones as the current generation of refrigerant gasses are being phased out, so long term servicing may be a problem. Not that they should leak gas.

You going to share it then. We like data on here.

Can you hack into one of those cheap replacement remote controls.

What may seem like a lot of heat may not be. Air takes 1 J.kg-1.K-1 to heat. So a relatively small cupboard may seem to be warm, but it has not taken much energy yo heat it up. All my lighting, if I left it on, draws 30W, I hate leaving lights on, but in the scheme of things, it is 100th of what my kettle draws.

Have you got some data to back that statement up?
