Hi all,
At the beginning of the year we replaced our old central heating and hot water system. We told the plumber we wanted a Vaillant ecotec boiler and tank, and he spec'd out a Vaillant ecoTec 630 boiler, a UniStor tank, a VR 65 control centre and a VRT 360 thermostat. This was to provide radiator central heating, hot water and drive wet underfloor heating which was to be added a few months later by the same plumber.
When he came to do the underfloor heating, he found that it didn't work because the stuff he'd installed couldn't control the underfloor heating as well as the radiators and hot water. Since this all began I've trusted the plumber less and less, so could someone tell me what Vaillant control parts are required to drive radiators, hot water and a single underfloor heating loop? I found the Vaillant control section on their website rather impenetrable...
The plumber tells me that one of the part we (he) needs is a VRC 430 weather compensator. This must be made from ground up diamonds by elves who only work on Sunday's before noon as they seem to be somewhat unobtainable... I want to understand why it is that the VRC 430 is required, as none of it's description seems particularly applicable to us.
Thanks!
Dave.
