So, the heating system that I inherited with this flat has a Volkera Sabre he 25 plus combi boiler and 8 rads, each with a trv.
None of the trv valves have caps on, so they have been fully open since the day I moved in.
I'm wanting to fit a few new rads as the current ones are too small for the respective room size and whilst I was at it, was intending to fit new trv's.
I know that if you have system with all the rads having a trv, then I would need an Automatic bypass valve.
Looking through the manual, (http://www.upperplumbers.co.uk/PDF/Manuals/Boilers/Sabre_HE_Combi_install.pdf
it says
3.6.2 AUTOMATIC BY-PASS The appliance has a built-in automatic by-pass. However it may be necessary to fit an external bypass should the design of the heating system require such. In any case, the design of the system should be such that it prevents boiler ‘cycling’.
So I'm left wondering if I need one.
And supposing I do, how do know the level to set it at?
In terms of where to position it.
Thanks for reading and advise.
