waterflow greatly reduced through combi

[geoff]

What boiler, what size is it, how old is it?

[John Rumm]

new 38Cdi combi he said in the OP.

Ah - ... I lost everything with a bad CRC file yesterday - a gap between the backup on the 3rd and now

38 CDi is fairly massive for an average house straightforward modureg control on the gas

leads to the question as to whether the 2ndry HE is scaled up or if there's a blockage somewhere

[John Rumm]

Yup certainly possible, seems a bit soon if it is new though. More likely the installer was a tad over enthusiastic with the manual flow limiting I would have thought.

The CDi range is non-condensing, so it can't be that new unless illegally installed

"Fully condensing in both central heating and domestic hot water modes" according to WB.

Actually, of course - I was thinking junior

completely different animal

its been a hard day

My reply doesn't seem to have appeared

Yes - I was thinking of the Junior not the CDi (C stands for condensing DUH!)

Its been a hard day

But still, its an old boiler- it was superseded by the greenstar years ago

[christopher]

It's a Greenstar CDi Classsic

No - I was correct the first time around the CDi range are NOT condensing boilers

The Greenstar range, however, are

[polygonum]

Isn't the OP's boiler a Greenstar 38CDi?

Central heating output: 30kW Domestic hot water flow rate: 16.4 litres per minute at 35 degree temperature rise (provided adequate mains pressure is available)

I think I am confused...

[geoff]

Yes, but the magic word "greenstar" was missing from the description I was given
