Well it is cooler than the outside air. Was your MVHR on summer bypass?

That is today's OAT, hasn't London just had 30⁰C plus for a couple of days? To only get internal temperatures in the low 20s when it is mid 30s outside seems a success to me.

Only 19p/kWh at a gas station. At 10p)kWh it is worth getting a CHP unit and some batteries. 20 kW is about 27 hp, so a small car diesel engine hooked up to a generator, with the coolant pumped around the house would supply that easily at part load (where it is most economic to run). May have to bury it in a bunker to suppress noise and have the air intake and exhaust pointing away from any houses, but should not be too noisy.

Half of the bleeders.

The guy who runs they surveying course at Camborne School of Mines was the surveyor in the channel tunnel. They missed, but not by much. I got the best marks when I did his baby surveyors course. More about decent record keeping than using the equipment I found. The theory is fairly easy, the arithmetic basic, but miss read an entry and you can carry that mistake all the way to the grave.

some installers grind the tiles, others don't.

Taught me to 'speak' BSL, and had an opportunity to use it tonight. Signing at you now.

No it won't. Well at least you did not mention head types.

Welcome Which end of the county are you?

Looks useful.

Yes, and you don't by governing the load, simple feedback governor. A smaller diameter 'wheel', as you say, needs to run faster (more RPMs) for the same power. With turbines, there is a different formula for gas and liquid ones, would have to get my old books out to find out.

Yes, bit like Physics and Phycology. If chippys want to be taken seriously, they got to learn the lingo of engineering. Probably save the lads legs as he could pick up the correct fastener first time.

Isn't this why we use pumped system and gravity systems these days?

To get maximum power out of an impulse water turbine, the turbine speed at the impellor tips needs to be half the incoming water speed (seemed to remember that from a lecture a while back). So if the water speed is 2 m/s, then for a 1 m diameter turbine (or water wheel), the RPM needs to be about 90.

200 mile round trip to my nearest John Lewis. Think I shall just drink in the street. This is our old PM

Or your site is on a slope. Or you have @saveasteading builders. Alternatively, bury head in the sand and hope for the best.

A permanent 1 W load (8.76 kWh/year) costs @28p/kWh, about £2.50 a year. About 3 days summer usage for me. Had a carbon footprint of around 2.5 kg CO2.

Use the right type of screws.

RESPECT Thank you. World energy use per person is about 2 kW. 48 kWh a day. This is obviously too high because of our dominant combustion technologies. And household usage is only a small part of primary energy usage, though, along with personal transport, the ones we notice the most as we are directly paying for it. Come winter my usage will go up to a mean of 665 W, 16 kWh/day. Too high for my liking, so this years house modifications are to add 'winter' secondary glazing, fix the back door that has visible gaps (fixed the front door last year), and find how air is travelling to a socket in the living room (been throwing out 2 decades of 'loft rubbish). When I first moved here, and being used to a crappy combi gas boiler in my old Victorian house, I did not pay much attention to energy use (even though I was studying it at university). My first full year usage was ~11 MWh/year. Whittled that down to under 5 MWh quite easily, to get to under 4 MWh has been difficult, but getting rid of parasitic loads has made a major contribution to that. I would like to get down to 3 MWh/year without spending a fortune, and having a house that is comfortable enough. Interestingly my motoring has followed a similar path, going from an old petrol automatic what was dreadful on fuel around town ~30 MPG, to a turbo diesel manual that consistently does over 50 MPG around town, 65 MPG on an upcounry run. I am not too bothered about what sort of car I have, as long as it is reliable, so shall have to give that some thought as mine has done over 200kmile and is making strange knocking noises from the front suspension.

Many a happy minutes doing Bowditch Corrections. Found this. https://civilblog369.blogspot.com/2019/01/levelling-surveying-civil-engineering.html

Seem like English, but not got a clue what you are talking about. I just water mine.

What I work so hard on. Here is some basic stats for the 01/06/2022 Data points 11,566 (~7.5 seconds) Zero power draw count 8,364 (72% of data points) Mean power 113 W Total Day Usage 2.7 kWh Proper job.

Can you export the raw readings as a *.csv file for easy playing about. This is what mine (home made) churns out.
