Divertor valve?

[Dannyparty92]

Hello everyone. On all new modern boilers is the divertor valve on the return? If so could someone please explain why because I thought if the divertor valve was on the return then if someone opened a hot tap the boiler would have to fire flow all the way though the heating circuit then in the divertor valve though the 2nd heat ex then you would eventually get hot water from your tap? Would it not be quicker to put the valve on the flow so hot water could get to the 2nd heat ex quicker and therefore not have to wait ages to get hot water from your tap? Any answers would be great thank you.

When the diverter moves the ch water stays within the boiler pipework. not sure if im allowed to go into great detail sorry. if you wait ages to get water from the tap its either a long hw piperun or a rubbish boiler.

 

[hammers4spanner]

think of a primary circuit within boiler , thats all i'm saying afraid

 

[lambchop]

Are you a student, the textbook will explain the answer to this mate

 

[hammers4spanner]

do you know the principles of how plate to plate works??

 

[Dannyparty92]

Yeah plate heat exchangers. If the valves on the flow then how come its so quick when you turn a tap on and it gets warm if the water has to go all the way through the boiler though the heating pipe work back to the boiler though the valve then though the heat ex then heat the mains water up then go from the heat ex to the draw off ha all that and it only takes a few seconds to get hot? All I want to know is how? Haha

 

[Whyme]

It doesnt go through the heating pipework.

 

[Dannyparty92]

If the divirtor valve is in the return as apposed to flow why would it not go though the heating circuit before the 2nd plate heat ex? If it was on the flow then I would understand because it would be before the heating circuit.

 

[hammers4spanner]

it doesnt go through heating pipework tho does it , the heat transfer is through plate to plate , think about it , plate to plates are honeycombed inside and pre heated water transfers heat to the cold incoming mains water which then very rapidly becomes hot . get it !!

 

[Dannyparty92]

I know that! The HEATING water has to go from the boiler all the way though the heating circuit back to the boiler then though the valve then though the heat ex then Pass the heat though to the mains cold water which then heats up then goes to the hot draw off. So why is the valve on the return?

ahhhhhhhhhhh no wrong wrong wrong !!!!!
whys it going out to the heat circuit?????
get your books back out

Because the diverter has stopped the flow of water around the heating. doesnt matter where it is if it diverts the water around the plate its prevented it from going around the heating (diverting).

 

[hammers4spanner]

probably get banned for giving out boiler advice now lol

 

[Dannyparty92]

Because its on the RETURN not the flow.

 

[Dannyparty92]

Oh so it justs stops the heating flow then bypass it via the heat ex near the flow?

 

[Billy Bob Bob]

Because its on the RETURN not the flow.

i have never seen a divertor on the return most are on the flow there will be exceptions but mainly on the flow

 

[Dannyparty92]

Don't the vaillant ecotech plus have the divirtor valves on the return?

 

[hammers4spanner]

are you in training??

 

[Billy Bob Bob]

Don't the vaillant ecotech plus have the divirtor valves on the return?

what side are they on viewed from the front of the boiler?

 

[Dannyparty92]

Yes but I don't intend to do any works on boilers without the supervision of a gas safe registered engineer and I'm aware of the forum rules.

 

[Dannyparty92]

Right side cause you have the flow,DHW,gas,cold inlet,return then the prv and condensate and its on the return the valve has like a black head with a little pin inside.

 

[hammers4spanner]

Just look at the schematic of the boilers parts in the MI's it will point oiut exactly where the diverter is

 

[Dannyparty92]

Iv just asked a question and asked for help. Half a brain? I explained to you many times I'm aware of a return and a flow but that's not the question I asked

 

[Whyme]

Iv just asked a question and asked for help. Half a brain? I explained to you many times I'm aware of a return and a flow but that's not the question I asked is it knob.

Its the fact you couldnt get your head around the water not going round the heating and kept repeating yourself, weve explained as much as we can on this forum any more and well be in trouble. that choice of words is a bit strong dont you think.

 

[Dannyparty92]

Yes I apologise. But if something is situated on the return then it's only logical to assume that it will go around the heating circuit first don't you think? And I thank you for your help and perseverance lol. I'm am aware that such information on this forum is limited to GSR forum users only.

 

[hammers4spanner]

nope,
hence the word 'diverter'

 

[hammers4spanner]

if your working on a combi tmoz then get someone to show and explain how diverter works and how the flow to heat incoming cold water works etc etc be easier for you to understand it then

 

[Dannyparty92]

Sorry

 

[Dannyparty92]

Haha oh dear. I understand how a plate heat exchanger works thank you.

 

[jtsplumbing]

What make boiler are you asking about ? maybe then you could get the answer your after !

 

[Dannyparty92]

Just boilers in general but I though the valliant ecotech plus had the said valve in question on the return? Perhaps you could shed some light on this heated subject?

 

[hammers4spanner]

theirs a sticky on this site somewhere for relevant boiler MI's look for the model you require and all info you need should be somewhere

 

[Dannyparty92]

Much appreciated.

wow another person asking a question who gets shot down, Shock!

wow another person asking a question who gets shot down, Shock!

and it has been dealt with accordingly,so your point is?
