New Boiler - hot water smells of chemicals

[Woody2244]

Hi, another question on my new boiler. When the hot water tap is turned on, as soon as the hot water starts coming out there is a very strong chemically smell to the water (and it also tastes bad). The small lasts for about 10 seconds, then is not very noticeable. It does not smell of rubber/plastic - it is more of a chemically/solvent smell. Have you any ideas what is causing this? Is it just due it being a new boiler (it is a Vaillant)? Alot of the pipework around the boiler was changed when it was installed, so could it be due to the soldering/solering facilitaor of the new pipes? Will the smell go away after the boiler has been in use for a few weeks?
Thanks

my guess boiler not flushed and commissioned correctly were they gas safe registered?????

I wonder if they put Fernox in the hot water circuit instead of the central heating by mistake?

the vaillant is foolproof it fills via a integrated filling loop,unhook the feed end attatch aerosol open valve on heating 25secs later all done then reconnect

The vaillant might be foolproof .... hehe!

May require a flush, could be flux in system. The hot water should not smell if your cold doesn't its the same water.

could just be a bit of flux in the pipework will go away soon

almost certain this will be the filling loop open and no check valve fitted or if fitted not working not all vaillants have the filling loop integral if its a pro its external remove the silver braided pipe after making sure its turned of seee if this cures problem
