Hello.
I have a Vaillant Turbomax boiler.
Downloaded the service manual for all the gas out puts etc at the request of the gas guy who is coming to service it tomorrow.
Just curious and was reading through it, most of it made sence but i have a question:
There are 2 heat exchangers in it - a small rectangle one at the bottom behind the front cover that you pull down and then a bigger one thats at the top of the boiler where the flames at that happen.
Why are there 2 and what do they do? (presume they have different roles)
Regards in advance
