Baxi Duotec 28 HE Producing much steam

jonaldo

I recently had a new Baxi Duotec 28 HE Combination Boiler installed to replace my old boiler. This produces much steam compared to my old one. Is it how this normal for this type of boilers. It only does that when you open the hot water tap and sometime when heating turned on. Its not a big issue but I thought as a newer boiler it will produce less steam

Looks like steam, but technically it isn't.

It is normal for a condensing boiler to do this.

A very general rule is that the more 'steam' you see the more money you are saving.

It also depends on the ambient weather conditions as to how visible the 'steam' is.

The water vapour is at a lower temp than with a traditional boiler (so it appears to produce more steam), which means more heat is extracted to warm your house and heat your hot water.
As gas4you says, it will not be so visible once the ambient temp rises in spring.
