Worcester Greenstar System CDi will operate in a sealed not pressurised scenario as they do not command a minimum operating pressure. Seal off the vent pipe with a manual vent, fit a non return into the cold feed and a decent isolating valve. Loop the returns. Have fitted this in the past to overcome exactly this type of thing.

Won't that affect the manufacturers warranty ? and I still need control over the cylinder stat looking at the sundial RF2 packs not 100per cent which pack I need wired programmer wireless cylinder stat and room stat thanks for the advice . Cheers kop

Either move the boiler to the airing cupboard or loft if possible or fit a system boiler. On old systems when sealed I fit an adjustable pressure reducing valve before the filling loop, turn it right down and also add an extra expansion vessel. Vessel charge needs to be adjusted for lower pressure set up.

Seperate system with a plate or header no need to pressurise then

Where do you buy your plate heat exchangers town ? Cheers kop

Having it sealed unpressurised is within the manufacturers recommended installation practices and does not affect warranty. Use a wireless thermostat as Danfos CET2000B for the hot water.
