Why would i buy a heatstore? Do they have some magical properties that a normal cylinder does not have? That might explain why they cost so much, i believe wizards are on £70k a year... Might retrain...

I'll try. I want to use the cylinder as a thermal store so I need to know how much heat is stored within it. That is, will it hold enough heat to keep a small building warm on economy electicity tarrifs without needing back up. Heat load of building will be around 10kw. Water holds around...

One for the physics boffs out there... How much heat (kwh) does a 300 litre cylinder hold.. Ta

i make it 14 kw per 100 litres of water. Not sure about kw hours joules etc so would love confirmation

Can anyone tell me how much heat water holds, ie how many Kw will be held per 1oo litres of water. Cheers, cowboy

I await for the good doctor with bated breath...

I been looking at thermal stores running on electric cos that is the only option available. Tey are fookin expensive. So my thinking is why can't I just get a massive cylinder insulate it to buggery, and have twin high recovery coils in it and use them in reverse to take heat from the...

Remove the 40mm from the 3" branch. Run the 40 mm into the branch and then pack it out and fill with silicone or putty .

A funny thing happened on the way to the forum. I think I am developing the skill of foresight. I saw megaflo, then I saw Dr Drivel. AND I KNEW what he had posted before I even read it.. For divinations feel free to post your questions. Mysticcowboy

erm, this sound crazy but it might just work. you could try a PLUMBER'S MERCHANT..

about ten to fifteen minutes on 15 mm . speed it up? heat it gently with that big flamey thing you use for soldering ;)

Do it for the time specified. Look for frost on the outside of pipe. Clench your arse cheeks and cut. Keep some speedfit s/ends in your pocket. Time will build experience. Large dia pipes take a loooong time.

Can you use a mandrill to make slip T's?

Condensate can only go in a CI stack if there is waste water entering from above. Ie below the highest entry point for waste or rainwater.

Think me pa was born in a coal cellar during a bombing raid in 1943, so it rules Viessman out too ;). Done some back of fag packet heatloss calcs and I reckon the ch loading is 10 to 11 Kw. Given two (mains) power showers running full pelt for eight minutes a day, I reckon that 250 to 300 of...

I know, I know. But he's an old embittered plumber, (and all too soon you will be too, instead of a young embittered plumber ;) ) I had visions of him sat there in his hovel heated only by a single-pipe 2" gravity system using injector T's, clutching his 24" stilsons tightly to his bosom as he...

Glad you saw the funny side DIA. All the best.

(3) Right angled drill ;)

Cheers lads, was just running the idea past you to see if it was feasable. i will work on some figures per requirements / heatlosses. As for the heatpump, he's not keen on the capital outlay, plus doesnt trust owt thats not solid state. IE post 1968 ;)

I've a bit of a project to do for me dear old pa. He's renovating an old wooden cabin in the wilds of derbyshire and there's no mains water or gas. there is electric, and i spent this week overseeing the drilling of a borehole (£17k :shock: ) . So we got electric 240 100 amp, and 6000 Gallons...
