I have recently had a new combi boiler installed, a vailliant eco tec pro 24, is this a good boiler?
I live in a 3 bedroom semi detached house, there are 7 radiators and soon there will be a bath installed as we only have a walk in shower, is this boiler good enough and efficient enough? what settings should the water and heating Temperature be at for efficiency?! and smooth runnings! and so i dont fall over when the gas bill comes!

It’s a bit late to aks now! You should have asked this question before you had it installed! If you told all this to the supplier then he should have sold you something that was efficient enough to deal with all your needs.
Vaillant make excellent boilers but the model you’ve got is a bit too small for your house in my opinion. It will work fine and heat the rads ok but the hot water flow rate is low, it’ll take you a while to run a bath. Bit late though now.
As for the temperatures the hw should be high and the ch mid range on the boiler with the room stat set to what you find a comfortable temp [about 20 degrees is average].
