New boiler new set up....

[freyster]

Hi Guys,

Really need some advise from this confusing matter.

Im currently doing a loft conversion and will have a bathroom on each floor.

I was looking to install a Vaillant System 637 boiler with a Vaillant Aurostor 300L water cylinder. As the pressure in the London area or my area is about 1.5bar, vairous plumers have suggested installing an overhead tank with a whole house pump or a 500L Actuator.

Im totally confused and not sure which option to go for, can any one help me out and advise me what the best solution is.

Ground floor and loft I will have a Shower and middle floor will have a bath.

Once the loft is complete it will be a 5 bedroom place.

Any help or guidance will be great.

Thanks
