I've recently had a new Vaillant EcoTec Pro combi boiler installed by a Gas Engineer and was wondering if I have been done by him by installing an inferior model. Reading the Vaillant Website it seems that the Plus model is much superior but can't really find out in which way other than having a extra years warranty.
Is the performance better ? i.e faster hot water flow rate. Also noticed that I can hear the boiler (like a furnace burning) all around the house apart from where I stand right next to it and it seems reasonably quite, is this normal?
Thanks in advance for any responses.
