Doctor Drivel scaremongering again, you have been asked before to show factual evidence of a single unvented cylinder that was installed in the UK exploding, you have been asked this many times and have always failed to show any evidence
To the OP don't listen to DD he has not a clue, unvented cylinders are fine, there are thousands installed in the UK, there are not as many heat banks though, don't worry about the stupid link he adds, that is an american web site all the safety devices have been removed, and it was obviously put under extreme pressure, I could make anything blow under the right circustances
Corgiman really covered your question in the first reply

 

[corgiman]

But If you are saying that an open vented cylinder and plastic tank are dangerous and we should have stopped installing them before that tragic awful death of that darling child, shouldnt we also stop fitting open vented heat stores, could the unbelievable course of events that killed that baby also happen with them?

On any heating or hot water system within a property?

.

whatdo iknow, you know nothing.

well at least im in the industry and licenced to install these rather than trawling the net to be provocative in posts

mind you you are right i no nothing im a complete absolute t****r
i say it every day
but they wont stop paying me

I keep telling them that about me mate

then they get me training other people

what do you have to do to get the tin tack so you can put your feet up

I ask ya whats it all about

I sell no goods.

If this is true then the following can be concluded.

1. You're a sh** salesman.

2. You have no experience supplying or installing the products you promote on this site.

or

3. You do have all the experience you claim and simply supply and install goods for free.

A couple of thermal stores I wish I'd photographed, dumped all their water through ceilings when they corroded through. That's what happens when you tell people they don't need any attention...

• Then there are the ones which cool the rads right down when you run a bath.
  Then there are the ones where you have to remove the heat exchanger with tedious regularity to acid clean it.
  Then there are the ones which are oddball, so any good repair man doesn't know quite how they're supposed to work, and yer average plumber hasn't got a chance.
  Then there are the ones where you have to have the radiators at 80 because the HW doesn't heat up quickly enough if you don't...
  ...and by the way keep the boiler out of condensing mode really well.
  Then there are the ones which frighten prospective property purchasers.
  Then there are the ones which are super efficient and really well set up - until they scale up a bit, and thermostats drift a bit, and requirements change a bit, and you need a guy with a multi channel temperature chart recorder to check it's running in accordance with the design parameters which he hasn't got so has to guess at.
  Then there are the ones which some dipstick who thinks he's smart put together out of parts from all over the world, before he went back to being a dipstick on the web. He would have got an immigrant who doesn't speak English to install it of course, as HE never dirties his hands.
  Then there are some which work OK.

Seeing that this has all gone off on a bit of a tangent anyway...
I been thinking about a heating system for me old pa's country cabin.
No mains gas, but its got electric.
I was thinking of getting an unvented with 3 immersions to give 9kw and using the primary circs in reverse for the heating, in effect making a heatstore.
Can anyone offer a more elegent solution? Just had a look at the pulsacoil and it say nothing about being used for heating... The water capacity of 75 l seems a bit low for use for CH...

I think you might need to turn it upside down to have the primary circs at the top.

Perhaps this...

Might be about as elegant as it gets.
Though perhaps too costly.

So you don't give away the goods, you don't sell any and no.2 is tripe. So where do you get your real life practical experience from?

depends o which models. The likes of the Systemate has the same water in the store that goes no where and does not mix with rad water. Gledhill recommend inhibitor but say it doesn't need any.

Then there are the ones which cool the rads right down when you run a bath.

Poor design as a CH pump interlock should have been fitted to switch out the CH when the DHW is calling. But!! The boiler being full on will re-heat ASAP, and the rads act as heat store in themselves.

Then there are the ones where you have to remove the heat exchanger with tedious regularity to acid clean it.

You do? The plates on the 100kW plate heat Xs flex resiting scale build up.

Then there are the ones which are oddball, so any good repair man doesn't know quite how they're supposed to work, and yer average plumber hasn't got a chance.

If they can't figure it out, he is not worth it anyway.

Then there are the ones where you have to have the radiators at 80 because the HW doesn't heat up quickly enough if you don't...

Poorly sized. Ignorance really.

...and by the way keep the boiler out of condensing mode really well.

You made that up.

Then there are the ones which are super efficient and really well set up - until they scale up a bit, and thermostats drift a bit, and requirements change a bit, and you need a guy with a multi channel temperature chart recorder to check it's running in accordance with the design parameters which he hasn't got so has to guess at.

They are few and far between.

Then there are the ones which some dipstick who thinks he's smart put together out of parts from all over the world, before he went back to being a dipstick on the web. He would have got an immigrant who doesn't speak English to install it of course, as HE never dirties his hands.

They are usually the best!!!

Then there are some which work OK.[/list]

Which is 9% of them - great baths and showers.

A vented integrated heat bank has a copper F&E tank that will not crumble. It is obvious that a water system with large plastic tanks that folds when hot is dangerous. We should have stopped fitting the eons ago - we should not have fitted them in the first place. This was predicted - but those making money from it and the hard of thinking (don't we have em here!) would not accept it until there was a death. Well all this was obvious not to you - to people like me it was. As are unvented cylinders.

How public spirited. Especially considering you've no vested interest in selling anything. Indeed it would seem your only deviation in life is to sit c*** in hand logged onto waterblast dotcom.

 

[billy bob]

Doctor Drivel how about the factual evidence of an installed unvented cylinder exploding in the UK, as you keep claiming they do this.
