That is right. Used to be called Pizza ovens. (there is a load of shit spoken about kitchen equipment, easy to keep clean should be the overriding criteria)

How to calculate heat load…
SteamyTea replied to G and J's topic in Energy Efficient & Sustainable Design Concepts
Here is some Lowestoft Met office Data. https://www.metoffice.gov.uk/pub/data/weather/uk/climate/stationdata/lowestoftdata.txt Lowestoft / Lowestoft Monckton Ave from Sept 2007 Location 654300E 294600N 25m amsl to July 2007 & from Sept 2007 653000E 293800N, Lat 52.483 Lon 1.727, 18m amsl Estimated data is marked with a * after the value. Missing data (more than 2 days missing in month) is marked by ---. Sunshine data taken from an automatic Kipp & Zonen sensor marked with a #, otherwise sunshine data taken from a Campbell Stokes recorder. Edited to remove the data - which ruined the scrolling - the data is available at the link above. -
Is that really the case, or a Daily Mail story? 2 minutes googling, it is a Daily Mail type story. https://www.hse.gov.uk/construction/faq-ppe.htm

The Health and Safety at Work Act (1974) is 50 years and 24 days old today. It has saved tens of thousands of serious injuries and countless lives.

Harvest it as a fuel. -
I am all for that, especially the females.

Seems high? Where did you get the data from? This is mean minimum temperature from the CET data set. The annual mean may well be around 6°C, but that includes all months, not just the winter. Just taking temperatures equal to and below 0°C, it happens 16% of the time, so 1400 hours a year. -
I still see work place bullying, thankfully not in our kitchen now. Gordon Ramsey has a lot to answer for and he should be cancelled, totally. I walked out of my last place because of the piss poor management from the new owner, not the first time I have done that. As for coping strategies, I have no idea. Was easy when I was lecturing, I pointed out two things. Every 15 minutes someone in the world gets their head kicked in by a Dr Martin boot. Then showed them my 'roll tops'. The other was more effective, pointed out that I marked most of their work.

Very neat. Do you have OCD?

Trouble with all things electrical on a building site is cable damage, and mud.

Just about 10p and hour, when on full chat, going up the flue now. -
Mine becomes half the length, so twelve inches, but I don't use it as a rule.

Yes, enjoy that morning tingle. Then if it continues, gen down the GUM clinic again.

Electrify it.

How to calculate heat load…
SteamyTea replied to G and J's topic in Energy Efficient & Sustainable Design Concepts
Quick answer is yes, no and you need to add to it. The longer answer is you need to know the total power per degree kelvin. Then you need to know your weather profile i.e. how often, in hours, it is -10, -9, -8 ......8, 9, 10....up to your heating off temperature (mine is a daily mean OAT of 9°C). Then you look that the middle 99% of that profile and accept at the negative temperature tail, you may need to turn on a fan heater. If you know your DHW energy demand, say 5 kWh/day, and your heating system is saying 5 kW, then you are heating water for 1 hour, so you have to make sure your heating system can, in the coldest days, supply enough energy in 23 hours. If you have ever lived in a place with a properly designed and executed E7 system, you will we used to this. You get all your energy stored in 7 hours (or less) then spread it out for the remaining 17 hours. In practice, you will find that your combined maximum heat load is not a nice round number that the heating system comes as i.e. 8 kw. So you have to round up to the next available size. Gas combination boilers are generally sized to deliver instantaneous hot water, so are often massive oversized i.e. 24 kW, but the modulate down to possibly a couple of kW power output for space heating, then start short cycling (what buffer tanks are used for). -
Close to where I work. How many traffic lights are really needed past the school, and can we get rid of the cycle lane and make it dual carriageway again. I have seen 1 cyclist use it, which is 1 more than anyone I know.

Which bit? I am confused as well with that statement, and that is allowing for @Dave Jones usual ridiculous 'statements of fact'. -
Newbie borehole-related water questions
SteamyTea replied to Kevin Dawson's topic in General Plumbing
I am not an expert on boreholes, but it is the flow rate of the ground water, not the volume of the hole that is important. -
Welcome. I like a bit of SE.

Newbie borehole-related water questions
SteamyTea replied to Kevin Dawson's topic in General Plumbing
As others have said, it is your pump that sets the flow and pressure. It is very hard to add a second, inline, pump. So your choice of pump and accumulator are the important things. My old 'holiday cottage' was on a borehole, but went via a header tank, then everything was either gravity fed or locally pumped (the farmer supplied the water from his large borehole, so he controlled the filtration, flow and pressure). -
Just make sure it is correct on the application.
