I've got a Glowworm Flexicom 30sx boiler & a Santon premier plus 170 unvented hot water cylinder with seperate expansion vessel. The PRV outlet from the Santon hot water cylinder uses the same copper pipe outlet as the boilers safety discharge.
It seems to be discharging around probably 500ml of water every 24 hours via the safety discharge outlet (to be clear, not the condensate). If I turn on the central heating & hot water seperately, there is still discharge i.e. I can't isolate it to either the central heating system / boiler or hot water cylinder.
The temperature of the central heating system on the boiler shows as 66 degrees.
Any guidance as to why this may be happening?
