Choosing the Right Vaillant Boiler

  • For Small Homes & Flats – Choose a combi boiler (e.g., ecoFIT Pure) for instant hot water and space-saving convenience.
  • For Larger Homes, go for a system boiler (e.g., ecoTEC Plus System) to handle multiple bathrooms with strong water pressure.
  • For Traditional Setups – Opt for a regular (open vent) boiler if your home has existing tanks and a hot water cylinder.
  • For Off-Grid Properties – Select an LPG boiler if you don’t have access to mains gas – ideal for rural locations.
  • Match Output to Home Size – Use this guide: 12–24 kW: 1–2 bed homes, 24–30 kW: 3–4 bed homes, 30–43 kW: 4+ bed homes
