Product Description
Heatmiser neoStat-HW v3 Hot Water Programmer – Glacier White
The Heatmiser neoStat-HW v3 is a hot water programmer with changeover contacts, making it ideal for standard and mid-position valve systems. It is designed to replace existing 230V three wire programmers and is compatible with standard and mid position (Y-Plan) valve arrangements.
Glacier White is the practical choice for the locations these usually end up in — halls, landings and airing cupboards, alongside white switch plates and light-coloured walls. It matches the white neoStat v3 exactly, so a full system installed in one finish looks deliberate rather than assembled.
⚠️ Hub compatibility: The neoStat-HW V3 requires a neoHub 2nd Generation or later and is not compatible with the original 1st Generation neoHub.This product must only be installed by a qualified electrician, and requires a wall back box with a minimum depth of 35mm.
