hi lads,

I just went today to a customer which wants me to convert his back boiler and hot water cylinder to a sealed system. He wants me to install a Vaillant 938 with 11 rads ( most of them are large 1400x600 ) and future 2 bathrooms.
He is worried that the pressure will drop significantly but I assured him due to my experience and based on Vaillant that it won’t happen and that the 938 will be fine. He is upgrading the mains water supply to 32 mdpe.
Will this type of boiler enough for future zoning? He is planning on splitting the zones in to 3 zones which are ufh downstairs, upstairs rads, downstairs rads.

However, at the moment his last radiator in the bathroom upstairs is only working half way ( vertical radiator). The difference between the F&E tank and the vertical Rad is about 10-20cm at max. Is that the problem why it doesn’t work in full?

Thank you for your help

@Matchless.plumb as I know you have seen my message but not replied. I am just going to leave this picture here. Please stop misinforming customers by using data that is not of any relevance in the uk. Start using the correct Vaillant data book. If you do not have one call the rep they will send you one.

I will get back to you shortly. I agree I have read your reply but due to my research I did not reply as i want to avoid MISINFORMING people. I will get to the bottom of it. If I am wrong I will apologise but I really doubt that these 2 boilers are not identical!

Research away mate. They may look identical and sound identical. But uk rules are much more lax than in Germany and that is probably why they are different.

You buy those boiler in separate packs right? Where does the cylinder come from, Remscheid- Germany ? Or Kent ?
Is there written VIH CL 20?

Alright, but they come in separate boxes?

Yes mate. But doesn’t change the fact that they are 7.5ltrs each in the uk

It makes a huge difference if your supplier gets them from Remscheid as these are 20liter storage and not 15. 3 months ago I installed a few which came from Remscheid and it has 20liters not 15.
If you see the description VIH CL 20 then you can be certain it’s twice a 10liter storage.

That is clearly a typo Ron. As you can see from the picture I have uploaded, the diagram is for the 15 ltr version. Also if you type the part number into any uk based search engine it only brings up the 15ltr vessels. Vaillant only sell the 15ltr version in the uk as far as I am aware. Vaillant uk only market it with 15ltr vessels. If your supplier is giving you 20ltr vessels he shouldn’t be, as it is not for the uk market and I am sure it will void the warranty.

That’s typo Ron I spoke to Vaillant today and he has confirmed that they get those tanks from Kent and from Remscheid. Which means the once from Remscheid are 10 Liters each. I have not got a specific supplier I order in different local stores so I am sure it’s not not illegal for them to sell those type of storage tanks.

You can lead a horse to water but you cannot make it drink. You believe what you will mate. As it sounds like you are going to anyway. I also spoke to Vaillant and they told me that the 938 has a 15ltr store so I’m happy that I am right. Good luck in what ever you do.

No point of arguing here harvest. What’s the point ? I don’t mind you being right ... I’m not here to fight or proof that you are wrong. I will keep misinforming my customers and you keep installing the 15ltr storages let’s put an end to this and talk about something else.

I would love to mate. But I do not work like that. Especially when I know I am right.

How do you know how I work mate? I do not think that I am doing bad jobs nor do I think I am cutt8ng any corners, ripping anyone off or false Information are given. Next time, I will take a picture of the storage I am installing. I have seen the manual and have seen the figures. Trust me, my work ain’t bad otherwise I would not have any customers nor would I work only on recommendations. I take too much pride in my work. However, it is ok if you want to be right that’s fine with me mate really I don’t mind to be wrong as nobody is perfect.

Ron. I didn’t say that I knew how you worked. I also didn’t say that you was doing bad jobs or cutting corners or ripping people off. I did however ask you to stop using the wrong data sheets and to not miss inform customers. I say this as I wouldn’t want it coming back and biting you on the bottom later on, that’s all. I know I have upset you and I honestly didn’t mean to. I was just trying to prove my point.

Clearly states for model vih vl 15 s / 10liter each vessel ... that’s sold in uk. You can use the part number 0020039781 and you can get that online heating spares etc ...

You really did not upset me.. I like discussing matters which is totally normal. I just don’t believe I’m so wrong ... I can see I can get the storage on English markets with the part number which indicates that you misunderstands the vih cl 15s that’s just the name of the boiler. If you type in the part numbers you can see that the storage comes up with 10 litres each. A lot of Vaillant
Engineers haven’t got a clue if you talk with the, on the phone. Just 2 days ago I spoke with one guy and he wanted to tell me I would need 3 bar mains pressure and 20l flowrates to be able to install this boiler. I had to call a different guy and he told me it was total boll.... the point I want to make is that I strongly believe that it’s the same boiler like Germany with a slight difference in kw output. We have 20 and 26 which is well enough but here in uk is 38kw

Ron. I am not saying that your picture doesn’t say 10ltrs. It does what I am saying is it is wrong code VIH 15 CL S refers to the 15ltr store and code VIH 20 CL S refers to the 20 ltr store. You may be able to get the 20ltr in the uk. But it is not supposed to be fitted to the boiler. As per Manufacturers instructions it states that the boiler has a 15ltr store. In the world of gas and gas engineers mate MI’s are god.

The boilers in Germany from what I have been told are a lot more Efficient.

Soooooooo true plenty of different type of boilers.. but again we aren’t in Germany. I get what you are saying above so let’s put an end now ?
