ASHP linked to log burner boiler
SteamyTea replied to Lewis88's topic in Air Source Heat Pumps (ASHP)
Think again. Only dodgy accounting methods that make it look carbon neutral. -
I bought a new car and had to pay a 10% new car tax. That car got written off, and after a few months, the I Durance paid out, bought another new car, 5% new car tax. Then the new car tax was dropped completely. Cars were the same price. So no consumer saving, and I doubt the dealer made an extra 5%.

Do you know the high costs, finacial and enviromental, of sold fuel combustion? A correctly sized, and opperated, ASHP should not be a problem in winter. -

But would seriously hurt the 50% left. I think we really need to distinguish what people mean when they say 'save the planet'. What most probably mean is 'save my lifestyle'. -

Just a snippet from this weeks comic. May be of interest to those that think all models are wrong. Some models are useful though. This Week Climate change made the past 7 years the warmest on record The UN’s World Meteorological Organization found that 2021 was the seventh hottest year to date, at 1.11°C above pre-industrial levels IN PALMDALE, CALIFORNIA, TEMPERATURES REACHED 41.1°C IN JULY 2021 ROBYN BECK/AFP via Getty Images The past seven years were the warmest on record as climate change continued apace, despite the cooling effect of the La Niña weather pattern in 2021, the United Nations has found. The UN’s World Meteorological Organization (WMO) analysed the six main global temperature data sets, which revealed that last year was the seventh hottest to date, at 1.11°C above pre-industrial levels. “The continued onslaught of record years, including the seven warmest having occurred since 2015, is precisely what we expect to see due to human-caused planetary warming,” says Michael Mann at Pennsylvania State University. Governments at the COP26 climate summit in November reaffirmed their commitment to trying to hold temperature rises to 1.5°C and well below 2°C at worst. But emissions reductions pledges currently have the world on course for 2.4°C or more. 2021 is the seventh year in a row where temperatures have been more than 1°C above pre-industrial levels. While only the seventh warmest year on average globally, 2021 saw climate scientists shocked by several temperature records broken by much larger margins than usual in some places, such as the near-50°C record set in Lytton, Canada. Previous research showed this event would have been “virtually impossible” without climate change. Read more: 2021 in review: Weather records aren’t just broken, they’re smashed “Climate change impacts and weather-related hazards had life-changing and devastating impacts on communities on every single continent,” said Petteri Taalas at the WMO in a statement. Although not a record for surface air temperatures, 2021 was another record-breaking year for heat content in the upper levels of the oceans, which are absorbing much of the carbon dioxide emitted by humans and the heat that this gas traps. The cooling effect of the La Niña weather pattern is expected to give way later this year to its opposite, El Niño, which was responsible for 2016 being the hottest year on record. The UK Met Office, which holds one of the six data sets examined by the WMO, forecasts that 2022 will be 1.09°C above pre-industrial levels.

Who knows. Does seem odd.

If a tax is reduced, or even abolished, in one area, another area, or areas, will have to have a corresponding increase. For at least the last decade, and probably a lot longer, the public have been told that they need to reduce energy usage. Now that there has been an unexpected, large price increase in cost, everyone is complaining that 'something must be done', but they don't want to pay for it. There is no magic solution here. No one is going to invent a small device that costs 100 quid and slashed an energy bill by 70%. Yesterday I used 20 kWh of electricity, that fed me, kept me warm, enough hot water for cleaning, allowed me to play on here, and let me put the lights on when I got home from work. It also kept my milk cool and fresh. I drove about 50 miles, so that will be another 45 kWh of usage. House energy cost me about £3, car £6.75. Two coffees cost me £5.50.

I would have though that changing the cylinder would be the cheapest, easiest and quickest thing to do. Or have I missed something.

That is how I got Firefighter and Evacuation. Here is the file. Datos-1º-trimestre-2021.xlsx -

There are viable alternatives, mainly mass migration and rebuilding. As far as the UK is concerned, we have voted that one out. Regarding the costs, we know what large scale off shore wind, large scale solar and new nuclear cost, and we know that large, off shore, wind is also 40% more expensive than large, on shore wind. We have voted to not have large, on shore wind. So we know the costs of some alternatives, and even though they are lower, we coted against them. -

My Spanish is not good enough to look at the data tonight. Saw Firefighter and Evacuation. Not sure where they fit into the data. https://www.goronadelviento.es/en/statistical-information-and-data/ -

I don't know if anywhere has one of those old gas storage things that used to be in towns. Be fun to work out how much energy they could store. -

No you do not remember correctly. I am neither a fan or a critic. I do like the idea of compressed air storage, but in old salt caverns (they already exist), not bottles and cylinders. That opinion pieces is a bit confused and I don't have enough time to unpick it. But. Is the system performing as designed, or not performing as expected? That may seem a quirky question, but if I design a beam to take a 5 tonne load with only a 10mm deflection, then I put a 20 tonne load on it, has the beam fails because it has deflected 150mm, it is not comparing the same thing. -
Whatever flow rate gives you the optimal temperature difference between flow and return. Does the ASHP state that temperature difference?

Is on my 100 quid from Currys. I suppose I should be a bit more precise. Chart shows the percentage of time that draw was under 1 Wh. The point is though, you can banish most parasitic losses if you want to. It also shows that for my lifestyle, PV would not be that brilliant, except I could shift the E7 loads to the day (about 14 kWh over 5 hours).

Would you not just freeze the water in any pipes. I think it is illegal to run a turbine from a tap.
-
Fridge only draws occasionally. My phone is my router. I have purposely tried to reduce all the parasitic loads I can. And it has worked. We too often swap convenience for ludicrously high environmental damage. Just don't ask about the 600 miles extra I am driving every week at the moment, in an old diesel as well.

I use low power devices. Phone lasts me a couple of days, tablet a week. The only things that are permanent plugged in are radios and laptop, both low power devices, oh, and the energy monitor/weather monitor. I monitor my power usage and it is not unusual to have 50%, which amounts to several hours a day, when my house is drawing no power at all. It is all about management, not the number of sockets.

Need to know all the relevant wall floor, roof/ceiling (depends on roof construction), door and window areas, along with the associated U-Values. Then it is just addition and multiplication.
