New Boiler - hot water smells of chemicals

[Woody2244]

Hi, a 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?
Any advice greatly appreciated.

1 you shouldn't drink hot water from a combi its not good for you.
2 is the boiler an ecotec? is the hot water warmstart active "C" will be displayed bottom right of screen?
3 this problem sometimes is caused by restricted flow and the water is boiled usually only very hard water areas get this problem (chemicals in the water)
