A pint of Murgy (clone). Very nice recipe this. Easy drinker

I do this too with the AIO - except I use the tub of protafloc to give it just the right angle. I get an extra pint or so out of the kettle

I have one of those small pink octopus mini dongle thingies

Overnight charge of the battery, heating up the brewing water and electric heaters during free electricity. Brewed in the cheap hours whilst Bert is battering us, along with a cooked breakfast Finished and cleaned up. Battery at full charge. Total cost for the day. Negative 4p. 👌

23L of disaster brew Belgian Blonde. Turned all the heaters on overnight to take advantage of free electricity. Forgot to put a lid on the sparge heater. Water was dripping from the ceiling in the morning. Pipework fell apart in the mash, so the overflow pipe fell into the mash and was a pita...

Definitely looking like brewing tomorrow now. Electricity is free until 10am. And I'll fill the battery up too so the rest of the brew can come from the battery

I might get a brew on tomorrow morning... But I'm on agile and it'll go to negative 4p/kWh evening, so I'll get paid to turn the fan heaters on!

Is it against forum rules to mention shares?

Yes. That was what I was asking. I didn't know that. Thanks 👍. Good explanation

This might be the root of what you are seeing. Boilers (especially modern condenser boilers) are more efficient operating at lower temperatures. This is probably one of the reasons underfloor heating might be more efficient - the boiler is more efficient as underfloor heating operates at a lower...

If the wall are up to temperature, then you've already put a lot of energy into them. I could counter with "it takes a lot more energy to maintain the temperatures of the walls than to let them cool down". If you maintain the temperature, putting the lots of energy into the walls sooner in the...

Again, citation needed. I have never heard anyone say that underfloor heating is more efficient than radiators. More comfortable, yes. More efficient? No. The slab will still leak energy into its surroundings. So if you don't let it chill down, you're still putting the same amount of energy...

Citation needed. I dispute this claim. Incorrect. If the walls are warm, they are still leaking heat/energy into the outside walls, so you need to maintain this as well. A simple explanation is that the total amount of heat energy in that you house looses to the outside world will need...

Cold air falling and hot air rising are two sides of the same coin.

I'm curious at to how did you measured this, because it violates some pretty basic laws of physics (thermodynamics)

CO2 is denser than air. Yes. Will the co2 "sink"? No. That's not how gases behave. A good analogy is to think about milk and water. They are close but different in density (like CO2 and air are) and mix according to the same laws of physics (fluids - both liquids and gasses are fluids). So get...

I did some calculations a while ago (for bottling rather than kegging, but you can just scale it up and the ratios work out the same). Essentially, yes, the headspace is significant. Bottle conditioning will have the yeast consume the oxygen, but with kegging you don't have this luxury I don't...

How much do people pay in heating costs per day I wonder. I work from home so we have the heating on all day. But even today, with the heating on all day (well not constantly, but on the thermostat), it totalled £4 and was about zero degrees all day outside. We have a pretty-well insulated...

Treat ChatGPT like a drunk sot down the pub. It might be right, but there is a good chance it's bollocks (afterall, it is just an amalgamation of what people on the internet have said, munged together with a good sprinking of randomness).
