Pump Overrun

[thebadleys]

Can any tell me how long the central heating pump should overrun by?

Mine keeps running pumping hot water round even when the room stat is not demanding heat

It all depends on your system and in particular what make and model of boiler you have.

You seem to want to keep that vital piece of information secret !

Usually no more than ten minutes , what boiler do you have and do you have two port motorised valves or a 3 port

Sorry guys,

new to this.

The boiler is a Worcester Greenstar CDi Conventional condensing with a Drayton Tempus 7 electronic programmer and a salus RT300rf Digital T/stat.

Sorry again not with it.

It would appear to be a two way valve "T"shaped.

If its conventional then its not condensing!

I expect its a heat only regular boiler.

Now whats its number? 42 ?

Hi Tony

The Manual describes it as a Worcester Greenstar CDi 30 Conventional Wall Hung RSF Gas Fired Condensing Regular Boiler !!
