I've had my boiler serviced each year (837 ecotec), the engineer inserts the sample probe into the flue turret & records the combustion readings ,thats all he does , I have purchased a sprint V2 analyser due to the fact it is costing me £98 per year for a service , WHY CAN'T I DO THIS? ,as far as i know all that is required is for the CO/CO2 ratio to be below .004 , as long as combustion readings are within tolerence what is the problem with testing @ the flue terminal myself? ,am also prepared to use my analyser on my neibours boiler too along with a nominal charge of £10 ,if i find CO/CO2 ratio exceeds action level then obviously time to call a RGI.
I am NOT asking for gas advice so please do not post back with 'we are not at liberty to advice',if this is the case i will push the 'ignore' button.
TIA.
