hot cylinder connections


Postby hamish72 » Thu Oct 23, 2008 6:18 pm

Simple question to those who know ?

Hot storage cylinder in back boiler y plan the heating coil connectors on the cylinder are male and about 33mm diameter external

In and out connectors on cylinder are female of 31mm internal diameter

Are these in fact what are advertised as 1 1/4 inch connections

The only connectors I have found to connect 22mm (coil) and 28mm (water) are discribed as compression ?mm x ?" iron are these the correct items

Im good at electrics but rubish at plumbing so waiting in hope
