Gas Hob - Barazza - So Weak and Slow!

tekton23

Hi,

We've had a new Barazza gas hob installed. Since first using it, for some months now, we've thought it was really weak and slow to cook anything. I've done some tests over this weekend and the burners are using as much gas as they are meant to. For example:

The main 3.5kw burner is burning at an input of 3.84 gross, 3.46 net
The middle 1.75kw one is at 1.91 kw gross, 1.72 net
The small 1kw one is at 0.96 gross /0.87 net kw

These tests appear to show they are burning more or less at what they are rated as.

I just timed how long it takes to boil a 1 liter pan of cold water with no lid on, it is 8 minutes 20 seconds. I think my little camping stove will do it faster than this!

Does anyone know what the cause could be? I am keen to avoid the £300 call-out fee I've been quoted for a Barazza technician.

I'm sure it's not dirty or blocked nozzles as it affects all three burners and it was liek this from new.

Thanks!

Which ring was that on?

Pans with no lid always take longer to boil than closed ones.

In a kettle (with a lid) it took me almost 5 mins to boil half a litre of water on a ring that was a similar output to your middle sized one.

So your results aren't very different.

Hi Tekton.
Wow - great descriptive post! All the figures are there
Q (a silly one, as clearly you are clued up) - are the flames blue and flamy? If yes - and surely they are, or else you'd be asking "why is my flame yellow?" -  then there just cannot be anything amiss?
As you say, your figures suggest it's outputting pretty much what it should.
What hob are you comparing it with?

What hob are you comparing it with? 

Or a similar question, what hob did it replace?

You can't compare camping gas (propane or butane) with natural gas because both have a higher calorific value than natural gas.
