mains accumulator

[GeorgeBramwell]

I think it was a simple enough question drdrivel.

If you have 9l/min from the cold mains, what flow will you get at a cold tap once the accumalator has improved it?

(I don't know, as I know nothing about accumalators, so would like to have the answer myself)

Personally I would have thought accumaltors would increase the pressure only and not the flow, but then hey, who am I to ask.

Ask DoItAll, he knows all the answers.

Come on DocDrivel, or are you suffering from Legionella, The OP has gone out and spent all this money with GAH, how much of an improvement can he expect.

Accumulators will do a good But Limited Job, the larger the accumulator the better the result, but you will have to consider the risk of Legionella and stagnation which does occur on larger accumulator systems.

A Break tank and Cold Water Booster set will provide higher flow rates and pressures, without having to oversize tanks etc therefore giving much less chance of stagnation

You really need to have a thorough Survey completed to consider ALL ASPECTS of the existing conditions, your expectations, and then a decision can be made on an informed basis.

But as for Accumulators being a one size fits all solution Mr Bramwell is way off the Mark

We are the last house on the main with a good 100 metres of 3/4 inch pipe going uphill from the road.I measured the flow roughly at about 12 litres a minute.

Dig this up and re-lay with large bore pipe. You only do it once!.
Simples.
Doitalls question is his usual ramblings. Not enough info to give an answer.
And even if he were able to provide the info he would never accept the answer.

Post all of it then norcon or the link, not just the bits that suit whatever you're trying to say.

As for this thread, the answer is quite simple, at 1bar the OP will not notice any difference, unless you count legionella as an improvement.

Don't know what you're on about.
If you have a specific question then ask.

You copied the above from another thread, how about a link to it.

 

[Norcon]

Still don't know what you're on about.
But if you think I copied something from another thread then I suggest you post the link.

If the pressure is fine they are the best option by far. No noise, cheaper, no power used to run. FAR MORE RELIABLE as well.

Now your learning Drivel.

If the pressure is 2bar plus I agree.

At 1bar they are a waste of money, as well you know.

I have had one work at 1 bar. The water company dropped the pressure. I went along and played around with vessel charge pressure and it worked well. One bar and a decent flow. You can fit a main charge pump that can lift to 2 bar but have a 10 litre/min flow regulator on it to comply.

Not in/around London. Which area WSuppliers use those figures?

Thames allow a mains pump without a tank as long as it pumps no more than 12 litres per minute.

A company make the Mainsboost Charger. An all in one pump charging kit. This can be use in conjunction with an accumulator.

Yes they do you moron, and if you look closely at the paperwork you will notice it has a break tank.

Oh you silly man!!!

MAINSBOOST CHARGER

WANT TO PUMP DIRECTLY OFF THE MAINS WITH NO NEED FOR A BREAK TANK?

In applications where where the mains water supply pressure is inadequateThe MAINSBOOST CHARGER unit is designed to be added to a Mainsboost system on the incoming mains water supply. The CHARGER will boost the mains supply up to a pressure of 2.5-3.0 bar in the MAINSBOOST
