As long as your boiler was installed by a Vaillant approved person and is serviced every year by a Vaillant approved person any issues will be covered under warranty so you’ll be fineThanks everyone.
You've all been so helpful, I really appreciate it.
I think it's highly possible I am worrying about nothing. I just worry we are damaging the boiler and will need to replace in a few years when we already spent £4.5k on it (inc the ecotec vaillant, the labour and a tiny bit of pipe changes).
I can't believe how little I know about anything about houses!
I hope to be a different person in a few years and able to give lots of advice to people who need it like you all do on here!(I don't think you all realise how much your help means to us - thank you so much!)
