I find that an unbelievable figure. I will have to look into it. Today, at work, I weighed the waste, worked out at about 25% of perfectly good food was thrown away. The really staggering thing is milk. Probably 75% thrown away. In the olden days, we would have just rejugged it. Not allowed to do that now. We also wrap our cutlery in paper napkins. A good 20% get picked up by customers, not used, and we have to unwrap them and wash them, then wrap them again. We are, according to a certificate, 'carbon neutral'. -
Planning Permission needed to modify houseboat
SteamyTea replied to Temp's topic in Planning Permission
Labour member Philippa Hulme said: “It fits beautifully with the eclectic mix of the harbour: you’ve got apartment blocks that look like boats, you’ve got boats that look like houses. That’s just part of being Bristol. I think it’s fantastic.” And a shed that floats. -

They are (expletive deleted)ing hideous, unlike the meatballs and gravy. Send them back. Did you choose them from the ColourClimax magazines. -

Mains Water Usage - What do you use?
SteamyTea replied to Ferdinand's topic in General Self Build & DIY Discussion
I was actually comparing the bills, which includes waste water, and surface run off. it is the waste side that is so expensive. We pay to keep the Atlantic Ocean clean and the beaches sparkling. Then total wankers let their dogs shit on the beaches.- 30 replies

How about picking the right balls and shooting at a number of narrow goals. The ball is either the problem or the solution, and the goal is the target. You may miss, but the overall effect will be closer to where you need to be than just leaving it up to fate and the free market. An example if this sort of policy is the Landfill tax. Companies and individuals don't want to pollute the environment, they want to do the right thing, as long as it is cheaper to do so. The problem with the LFT is that it is now very expensive, and the chances of getting caught, and the associated fines, are relatively small. So the ball is waste, the goal is proper disposal. Make it easy to dispose of it, and it will be disposed of correctly. -
Green Home Grant application - have you had a response?

@Dave Jones Just spent 2 minutes looking up the price of the above ASHP https://www.cityplumbing.co.uk/Vaillant-Arotherm-Plus-7kW-0010037213/p/477547 Can save almost £2500 before the haggling starts. -

I shall try and remember to look up my figures when I finish work. Southwest water is the most expensive in the country. 8 times the price of the City of London.- 30 replies

Probably need a lot more information for a definitive answer. Knowing the surface to volume ration helps, cooling is nearly all about volume. PV on a roof will take out energy when it is sunny, reducing heat load. Also have a look at air to air heat pumps, they can heat and cool, and are very cheap. How do you want to deal with domestic hot water, stored or instantaneous? 30 m² is 2/5 the size of my place, and I use night storage heaters and a 200lt hot water cylinder.

I am taking this a little bit out of context (of HPs or gas), but am interested in narrow goals. Is it not a case that the UK is not working in isolation, we are part of a global species. Most countries will be taking a different approach, but with the same aim of net zero. There will come a time, possibly in the not to distant future, where only goods and services must meet a minimum criteria of carbon emissions or they cannot be purchased. As long as this is audited correctly, then there should not be a problem. There will always be odd ball situations that skew the figures i.e. County A may have higher agricultural emissions than country B, but lower industrial emissions. But the idea is to get divergence to, initially, net zero. Carbon negative can come later, but not too late. I don't think we need to particularly do this via austerity i.e. heat your house to 16°C rather than 20°C, but we will need to be careful of marginal gains i.e. a factory that makes heat pumps that have embodies carbon at say 10 units per HP, overproducing to get the unit value down to 8 units and they then just sit on a shelf (we used to have 'food mountains'). How each country does this is rather irrelevant i.e. nuclear, RE, efficiency gains, tree planting, CCS, the idea is to get to net zero. Also worth pointing out that land is only around 30% of the earths area, there are huge carbon sinks in the oceans and seas. There are also huge risks of acidification, rising temperatures, overall sea level rises and the more devastating storm surges. So I don't think a narrow goal is the problem. The problem is getting the ball into the goal. -

Try way back machine. He may have dumped the buffer, it was there when I last visited. Not sure if the slab mass makes a lot of difference to the cycling once it is at operating temperature. More to do with the flow/return temperature differences. A kg of water needs 4.2 kj to raise it a kelvin, concrete only needs 0.8 kj. So a kg of water is worth 5 of slab. And all the water can be heated, but there will be a temperature gradient with a slab, which may effect performance.

He had a buffer. He also used to to preheat water going into his original Sunamp and to recharge the Sunamp.

Half the customers on that job were happy. So that made 2 our of three of us there. If it had been a vote for BREXIT, I would still be in.

Here is someone I know. Scroll down to see his name, no wonder he has a stutter.

When I was in the PV industry they changed the MCS rules about fitting inverters in lofts. One of the rules was boarding from the hatch to the mounting area. My boss just saw this as an extra expense. The electrician we used said it made for a much quicker job to fit the inverter. Fitting loft boards takes minutes. Why would anyone not do it.

More a reflection in the borrowing and earning potential between I side and outside the M25. And people from Treacle Bumstead are tossers.

Yes. Why I did it for a couple of years when I needed extra cash. Small capital outlay, very cheap insurance, and everything fitted in the boot of a mid 90s Corsa. Could earn 3 times the money in Harrow compared to Hemel Hempstead. Only got thrown off one job, but that was nothing to do with the decorating.

First rule of statistics: Is the number big. It was our old mate @Ed Davies who pointed out that the UK produces more 'area' of cars than housing.
