That is about environmental policy, something I think needs to be tightened up a lot, not housing policy.

Why should I pay my local council to build a house for someone else. Did you give a new car to anyone that could not afford one?

Trouble is what is derelict to some, is a wasted opportunity to others.

Down here in Cornwall, some small town have a policy that only 'locals' can have houses built. The definition of 'locals' is so wide that most people can claim it. It has also stopped development dead in some towns. In the town I work in, my council has subsidies housing though a shared purchase scheme. So the locals borrow money on 25% of the property and pay the council a rent on the other 75%. Then they get stung for service charges. And, and this is what narks me, I am, though my council tax, subsidising the building of other peoples homes (I am also topping up council workers pension funds, but the council is not topping up mine). I don't understand 'localism'. I looked at my birth certificate and never noticed that it said I have the right to buy an affordable house where my mother decided to give birth to me. And if that was the case, should it mean that is the only place I can live. I was involved with a planning consultation group a while back, they were objecting to some houses being built. I suggested that the easiest way to stop the development was to buy the land. For some, unknown reason, I became very unpopular. Seems to me that people think that everyone else should pay the price to preserve what they have. If you like a view, buy it, if you can't afford it, tough. Regarding remote locations, that some people desire, there are other ways to make them exclusive, increased transport costs, utility surcharges, council tax surcharges (though I was a fan of the poll tax) etc. There are also ways to make urban living more acceptable. Mainly better design of housing, services and open spaces. There is a bit of a myth that larger houses cost more money, but when 2/3rd of the value is in the plot, and there is a limited amount of money to spend on housing, then the plot prices drop, this evens everything out. As for building on agricultural land, not many farmers sell off there most productive land, they sell off the rubbish. Down here most of the farm land is grade 3b and below. Or usually refereed to as wasteland. The good land is generally used to horticulture, as that is currently profitable. The land below it is generally used for early crops because we are a month ahead of the rest of the country. But that is a bit silly in a global economy, we are not a month ahead of the Spanish, or the USA (no one really tastes the difference between English or Dutch new potatoes, or Welsh and New Zealand lamb, people have just bought into a marketing campaign and pay extra for their stupidity). So I am all for relaxing planning laws, but tightening up environmental ones. We could then end up with better housing, and probably at the same prices we currently pay.

Try putting the swear filter to the test, I got away with it once.

Shut the thread down, it mentions BREXIT.

Yes, I forgot you were there and she was looking at you.

Yep, as Fiona Bruce said, 'so nice to see an old friend'

I made a suitcase from mine, can get a months worth of clothes in it. (and if I rub it hard, it swells up and becomes a policeman)

How do you manage that in your small, stubby, inbred fingers.

I only worked and played there. Don't think I did anything of merit. Not even at work (was one of the worse places I ever worked, I once managed 3 days in a row doing nothing, and no one noticed, so took the next day off, and no one noticed that either).

Once all 27 other devices agree. And then only after 3 years of debate and watering down to fit the one trouble maker. (I was trying so hard to be balanced)

The BREXIT Bridge. So it will fail to communicate, crash out as the best option, not consistently apply established protocols, cost more and offer less. But it will be "world class". Just as long as your world is tiny and closed. Some good engineers and theorists from there. Not rubbed off over the generations. Still, it accounts for your humour.

Yes, Windows. Would make a fine server.

By vastly improving the inefficient Bolton and Watt steam engine. This made mining more profitable and allowed people like Humphrey Davy to develope chemistry and physics quickly. This led to the development of electrical systems used by Marconi, who sent the first transatlantic radio signals from Cornwall, which also had the main global telegraph network. So if you need something done, get a moaning, pasty munching Cornish to do it. And, we did not need slave labour like Bristol.

Yes, but more for a better CoP. I have heard that the technology is changing for the last decade, or more. Not really changing, just a few different chemistries, nothing radical. You can get a roof integrated system that can work out cheaper than fitting tiles/slates. One area that it can help a lot is if you need to 'reverse' the ASHP for cooling in the summer. Any kWh generated and used is a kWh not imported. So true.

Welcome Steve. Are you at the millionaires end of the street or the other end, the multi-millionaires. Used to work in Marlow, and go kayaking from under the bridge. Have been known to jump off it for a laugh.

I did some work for Monodraught and was amazed how good sun pipes are. I also think the is a lot of scope for innovation. I have a dome and a diffuser kicking about still, would go well in my bathroom.

It may be possible to utilise the MVHR to extract air from the living area and deliver it to the sleeping areas. There may be enough of a temperature drop to deliver the fresh air at an acceptable temperature. You would still need to introduce fresh air to the living area, and extract from the sleeping area, but this may just be a case if adding two inputs to the sleeping area for every one extract, and visa versa in the living area. Should not be too hard to calculate.

The energy source can be anything, heating, lighting, solar gain, people. The energy is just dispersed to the atmosphere, which is generally colder, or, for the proper scientific term, a semi-infinite heat sink.

Is the converse true? Can go up to 15m2, be less than a metre from boundary and be made from flammable material?

The volume becomes a bit irrelevant when the temperature changes are only affecting the first few millimetres. This is why it is the product of the SHC AND thermal conductivity.. There are materials that have low SHC and high thermal conductivity, metals being one class, but there are not many materials that have high SHC and low thermal conductivity. Below is the data from my 600mm borehole that is under my little grrenhouse. Once you are 300mm deep, there is little variation in temperature, approx 5°C, with temperature swings of 32°C within the greenhouse. This reinforces my believe that excess mass with the 'wrong' thermal inertia will cause cooling rather than stability.

Basically you have a choice of two systems. An electrical, in line, resistance heating element, or a fluid filled 'radiator'. The electrical one is easy, it just plugs into the mains, the other is then really up to you how you heat the fluid. But if you are using an ASHP to heat your domestic hot water, it can be 'tapped' off that system. Some MVHRs (Genex for one) have a build in heat pump to add to heating and cooling. This is really two questions. How does a heat pump work in practice? and what is the best way to control the complete system? At its most basic, a heat pump has a hot side and a cold side. The plumbing within the heat pump will control which side is piped into the house. Basically there is the refrigerant pump, then, via some heat exhangers, some pipework to a radiator (the air source bit) that is outside, and some pipework to inside the house (the source or sink) for space and\or water heating. Just a case, depending on what you want, as to how the control valves reconfigure the heat exchangers. As for the house heating controls, this is a bit more complicated as it is very much dependant on the shape of the house and the usage. It is usual to zone areas and control each zone separately. That way you can have different temperatures, at different times for heating or cooling, is on and in different places. What many have found though it that having just one zone for the whole house is often good enough, and can be used to move excess heat around if needed, without using the heat pump (just pump the water in the UFH about). One thing with heat pumps is that they need to be designed correctly for the expected heat loads. This usually means over sizing them as that keeps the coefficient of performance up. Most modern ASHP have variable speed motors in them that accommodate this. It is also worth getting to grips with the difference between temperature, power and energy. They are not the same thing. You can have high temperature, but low energy and low power, low temperature and high energy and power, high or low power, medium energy and variable temperature. All a juggling game.

He better sue his installer, MCS and his DNO\meter reading company for this.
