Just about to take the plunge and replace old, defect Potterton open vent boiler with a new system boiler and pressurised cylinder.

I've been quoted for both Alpha and Vaillant but am not sure about quality differences, any advice highly appreciated

Vaillant best by far


htg

i second that. vaillant all the way.

the alpha is not as good as the vaillant and you'd probably have trouble finding spares and engineers willing to work on an alpha as well
