Do I need to get BDR91

[Number34]

Currently have CH controlled by CM927 only with conventional TRVs on radiators. Am considering moving to Evohome and wondering whether I have use a BDR91 instead of my HC60NG?

When you buy a Evohome a BDR91 will be included in the box. But you don't need to use it. Your HC60NG will be fine. These are infact now becoming sought after because of the higher rating that can be used for some electric UFH zones.
