Vokera 20/80 RS Flowmatic - Mira Combiforce?

[destro404]

Hi,

From what I read the Mira Combiforce is a good choice for a mixer shower but the combi has to be "fully modulating" apparently.

I have tried searching to see if I can tell is mine is or not and I'm still uncertain.

Can anybody confirm if my boiler is fully modulating and therefore suitable for the Combiforce?

Rigth so I have continued trawling through the web and from discussions of people replacing parts this boiler appears to have both a modulating valve, modulating coil and I'm sure also a modulation pcb.

Are these good signs?

Do you knoiw the difference between step modulation and full modulation?

No I don't, but I'm going away to look now! How is it relevant?

For delivery of hot water, makes very little difference. Obviously, full modulation will deliver near enough flat temperature response. Step modulation will result slight swings of temperature but hardly worth loosing sleep over.
