Vaillant vs Viessmann

Both German manufacturers bring precision engineering and premium build quality to the UK market. While Vaillant has a longer-established UK presence and larger support network, Viessmann often leads with innovative technology.

Key differences:

  • Vaillant offers more extensive UK support infrastructure and parts availability (98% next-day)
  • Viessmann features unique Inox-Radial heat exchangers and slightly higher price points
  • Both offer 10-year warranties, but Vaillant has more registered installers
  • Viessmann dominates European markets; Vaillant leads in UK commercial installations

Our verdict: Both excellent choices, with Vaillant only just edging ahead for UK support and engineer availability. Viessmann offers premium build quality and superb highly configurable smart technology, especially the Viessmann Vitodens 100-W with OpenTherm
