Is my boiler condensing?

[stottyboy]

I have an Ideal Vogue C40 Gen 2 40kw combi boiler hooked up to a 10 radiator CH system. Recently I have balanced the rads and now have a feed temp of 60 and return temp of around 40 degrees. I’m not sure the boiler is condensing. There’s plumes of vapour coming out the flue and the onboard efficiency monitor seems to always be at 40%. Any suggestions?

Return is well below 50 yes it’s condensing ignore the efficiency bar

I'd say yes but configured to open therm you will add savings providing your control is compatible your boiler definitely is . Kop

Thanks folks. Can I use Opentherm with the Ideal weather compensator kit? Will they conflict or compliment each other?

Nope either one or the other

Nope either one or the other

Is it correct that Opentherm is the better of the two as it allows smarter calculation of CH characteristics rather than just a supply temp adjustment from the weather compensator kit?
