WAVIN (Hep20) UFH Actuator - is newer model compatible?

[DevsAd]

Hi.

Mil's UFH has Wavin 230V 2W actuators - model 1026. One went 'pop', and I've ordered a replacement, but the fellow that turned up is their newer model, the 35CS498, a one-watt jobbie in a straighter-sided body.

I've asked the seller - the Underfloor Heating Store - if they are fully compatible - straight swap - but thought I'd ask on here too, since they can seemingly take a few days to reply.

So, anyone know if they are a DIRECT replacement, with no mods required? Are 230V models going to become tricky to source - that's the only supplier I could find?

Or are there any 3rd-party actuator heads that will fit exactly?

Thanks.

Just to confirm, they are a direct swap - clip on to the same ring, and operate identically.
