Is flame on gas heater too yellow?

[Mel256]

Hi All,

The heater seems to be running fine, but I've read around and seen in a lot of places the flame should be completely blue, mine has a bit of yellow in it. I have a new monoxide alarm and its not going off.

Thanks so much,

Does look a tad yellow but off the pics it's a bit hard to say.
What make n model is it ?

 

[Last Plumber]

When did you last have it serviced?

 

[Mel256]

Its a delonghi SBF like this: https://www.amazon.co.uk/DeLonghi-Silver-Portable-Heater-4-2kW/dp/B002KALCXC

But ours is second hand only a few years old I think very good nick from the outside, hose and regulator look very swish.. bought from a family friend.

 

[Mel256]

Haven't had it serviced, only had it a few weeks...

Is it in a room with ventilation?

 

[Mel256]

No ventilation really as its pretty cold! its around 600 square foot the room size

What room and how Big is the room?

 

[Mel256]

Do you know how many cubic meters the room is?
Is it in a room or an internal space?

 

[Last Plumber]

You're answering these as i'm writing them lol
are you psychic?

 

[Mel256]

Haha maybe! 600 square feet is around 55 square metres.
Not sure what you mean by room or internal space? outside the room are corridors and other offices and one long wall with large windows. Its got circulationa round it.

Theres no gas smell I have no headaches or anything

In a room:-
Heat input not to exceed 4.75KW
MAX Gross input 50W per Meter cubed of heated space.
Ventilation = 50CM2 plus 25CM2 for every KW above 2 kw gross input, direct to outside air.
Must have an openable window.

Chances are that the air has become vitiated.
You need to turn it off, stop using it until the issue is dealt with.
It may not be emitting Carbon Monoxide at the moment but it will !!

 

[Mel256]

Thanks, I have put the heater next to a window open for about half an hour and theres no difference with the flames? Do you think its still a ventilation problem?

 

[Mel256]

Im taking it to get serviced today though, seems like a lot £30!

If it's still yellow then yes it needs looking at.
Don't use it at all until it is dealt with.

£30??
Seems a lot? What were you expecting out of interest?
I would be charging you a lot more than that.

How are you " taking " it to get serviced?
It needs doing in the room that it is fitted in. To simulate normal usage.

Howdy Chalked.

Carbon Monoxide has no smell so don't go by that.

With a 2nd hand heater.....
Check to see which gas the heater should be using, and check that's what's being used. Just in case someone has fitted a different regulator.
The person doing the service should check that.

Please get it checked/serviced. I agree with Davey, probably a pressure or gas type problem. It probably has a oxypilot which would be starting to lift off if the room was vitiated. The yellow on the pilot and main burner suggests to me that the gas pressure is low. Or it’s full up with dog hair.

you wouldnt get any change out 0f £60 for a service from me whoever does it has to be certified for lpg

Hello Mel256,

Can You verify that You mean that the Room is approx. 600 square feet in area ?

Am I right that You don`t mean Cubic Feet - the Room VOLUME ?

IF You mean that 600 square feet is the approximate Area of the Room - guessing that there is at least an 8 foot high Ceiling that would give an approx. Room Volume of 4800 Cubic feet ?

Members are completely correct in that whenever there is ANY kind of query on a Gas Appliance it should not be used until it has been Inspected and if necessary Serviced - in this case by a Gas Safe registered `LPG qualified` Gas Engineer.

As Member Last Plumber stated `Purpose provided Ventilation` IS required for that type of LPG Gas Heater irrespective of even a very large Room size.

That means that even after it has been Safety checked & Serviced the Heater should not be used in a Room that does not have a permanent Vent of the correct size - direct to outside Air.

Regards,

Chris
