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,

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.

Is it in a room with ventilation?

 

[Mel256]

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

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?

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.
