Hi,
Just started doing my gas course and we went through on my course the calc for gas rates and working out heat input etc.
I have just done a gas rate on my hob and it seems there is a discrepancy of 1 between my reading and the MI. Assuming the heat input figure in the MI is always in...
We fit a few Vaillant Ecofit Pure system boilers, usually the case when an old Heat Only boiler goes and we replace with a system rather leaving OV, better all round solution. Ecofits are great as they're rear flues and fit in cupboards.
So when replacing we usually replace like for like in...
Just wondering what other engineers views are with regard to checking the heat input and burner pressure on landlord safety inspections.
The guidance tells us to verify the heat input and/or operating pressure of the appliance, however in a lot of cases the actual appliance kw data is not to...
hi,
IF appliance data plate/installation manual says HEAT INPUT - "35 KW" then what should we consider kw as a GROSS or NET? I got two different answer . My college instructor says GROSS and my mentor says NET.

Hi all, I've never actually had it occur but I was just wondering when servicing what is the procedure if an appliance gives an above maximum KW/mbar rating or below minimum KW/mbar rating. Thinking back to my ACS and can't for the life of me remember being told about this. Cheers
Hi, I am doing my ACS and just want to understand something more clearly.
- I have a Baxi solo 2 40 PF.
- M.I's state max heat input 14.65 kw and min heat input 11.36 kw.
- Max burner pressure 16mbar and min 10mbar
My question is if the recorded burner pressure was at the lowest eg. 10 mbar...

when gas rateing an appliance ,modulating burner an old timer told me the final calculated kw outcome should be more in line with the mi heat output not heat input.
doing my acs at the moment just a general question when you put a boiler on calibration mode for example the baxi duotec combi and you have worked out your gas rate and heat input calculations , what input do you refer to in the manual to compare it to ? i know its gross but is it the CH or DHW ?

Hello.
If i know the HEAT OUPUT of a gas fire for example how would i use this to calculate the heat INPUT of this appliance if the data badge is not available. what is the correct formula for example if my heat output on a fire is 7.5kw ?
thanks
