Yes folks, its cheaper to heat with electricity!

[Doctor Drivel]

How about the Severn and Mersey barrages? They will give about 8% of the UKs power if built.

[Doctor Drivel]

You did not understand. The unvented cylinder is converted to a thermal store. The hot water in the cylinder is pumped through a plate heat X which then heats the UFH

All you need is:

- a plate heat X. A 100kW will do, as used in Gledhill Systemates (about £80-90)

- a Bronze pump (about £60 on Ebay)

- A more powerful immersion heater (around £100)

- some pipework and fitting.

You say you only need 10kW for the house. A 9 to 12kW immersion, which can fit a 2 1/4" bosse will do. You have the advantage of storing the heat overnight and then a ready supply of hot water in he morning for the UFH. You say the UFH can only absorb 5kW, so no probs.

I would go down this route.

No floor standing cast iron jobbie with 12 gallons of water in it. Most of the time it is very much oversize for our use. It's there to heat what is effectively two 3 bed semis.

I've got 100amps 3ph:-) They may not be prepared to sell at *off peak* rates though.

I'd probably use a PLC. If I knew then what I know now when I designed the current 4 zone, single boiler, twin pump system with pump over run I would have used a PLC rather than relays.

Wires work. We do have a radio based programmable room stat. Guess which single stat, out of 9, gives the most trouble...

Roughly 1p/unit input.

Should be able to get 30% bearing in mind that the room with the wood burner won't need any heating.

Well I'm not bothered about the CO2, the carbon was only taken from the atmosphere in the last 50 odd years and we have 800 odd new trees growing in the paddock. I don't think the local sheep are bothered by a bit of smoke and the nearest neighbours down wind in the prevailing direction are several miles away the otherside of a fell...

Not to mention how fast this country would lose any tree bigger than a large sapling.

[Dave Plowman (News)]

Nothing like it - I believe we sail quite close to the wind these days.

Of course you could reduce the peak demand from a boiler by storing heat on all but the very coldest of days but I wonder what that does to the efficiency?

I also suspect since oil has gone up so much electricity won't be so far behind. No country is going to sell us any energy at less than the going price - and that includes gas.

The message from The Natural Philosopher contains these words:

Under these circumsfances you just might -- albeit as an almost woman :-)

[Andrew Gabriel]

Nothing like. Normal UK load is around 40GW, and peak load around 60GW. We've had peaks in the last five years where we were we had only around

1% spare capacity with all generation plant that was working online (very close to rolling blackouts).

and the supply network isn't sized for that sort of load from many houses at once.

Has anyone here managed to homebrew one of these? I did some reading up on them a few weeks ago and the theory seems easy enough, but I'm not sure how specialist some of the bits need to be...

(air-source isn't practical around here due to low winter temps, but ground-source should be possible)

[Theo Markettos]

And there I was thinking that you were planning to install electric heating by fitting a few server racks in each room. Might as well get some computation cycles for the electricity. 'nice' is your thermostat :)

The Democratic Republic of Congo wants to build a hydroelectric project that if it were possible here would supply the UK with all its electricity needs, with the potential to supply the entire energy needs of a country the size of the UK. Obviously in energy-poor Africa the clean, renewable energy would transform lives for the better. And it gives Congo the potential to be a serious industrial contender. Rather as hydrothermal power is making Iceland a leader for companies wanting clean, cheap power.

Usurprisingly the melons (green outside) want to get thw DRC project stopped.

there is nowhere else that I can think of

[The Natural Philosopher]

Thats oeof te things thathappes when yopu dont 'go in to work'

Yes, its a load of T-shirts and socks and underpans every week,but NOt shirts, suits, ties, and if you skip shaving and a bath for a day or even two, its no ones business but your won, and saves power and water.

[geoff]

'kin hell - six words without a spelling mistake

must be a record for you

[The Natural Philosopher]

Yes One of my most vidid memories of te Isle of wight festival - the first one - is arriving there a day eraly and campoing in the corner of a field by a nice little copse, and leaving in the Monday with the wood gone, and having been replaced by what amounted to an open toilet.

Back to nature, in terms of the vast majority of people, doesn't work.

[The Natural Philosopher]

Hmm. Not a bad idea: relocate the servers to the coldest room that is used regularly.

[Doctor Drivel]

What size is your cylinder in litres?

[Doctor Drivel]

Maxie, people have CDs these days.

[Doctor Drivel]

When was that? Why? What event caused that?

And the rest of the family!

Not shaving saves a few watts, I suppose.

But two kids seem to get through a lot of clothes, what with school uniform *and* what they change into later.
