Cold feed too combi boiler

Pinoy adventure

Hi

just got viesmann gas combi boiler fitted.

they pump is up in the attic which pumps down too combi.

is the CW feed meant too hook up with the Cold feed too fixtures and t off too supply the combi also or should that be a separate supply ??

The cold feed to the combi boiler will be the same as is suppling other cold water outlets in the property.

Ideally, I would have the feed to the combi coming directly from the attic and connected close to the pump, as it may provide more stable pressure in use than a single pipe with T’s downstream. In practice however a good pump, and particularly a constant pressure model will solve most problems.

Basically what we done is ran a 3/4 cold supply from pump in attic too the combi boiler in a below bed room.

the cold supply too fixtures comes up underneath the boiler so will have too get the pumped 3/4 pipe into the combi and the easiest thing too do would be t it into the pipe which supples downstairs and the other outlet on the T into the boiler ?

hot outlet on boiler is directly going too the hot fixtures including t bar thermostat shower in the house
