Which Viessmann boiler is right for you?

We fit two boilers from Viessmann's Vitodens range. Both have a stainless steel Inox-Radial heat exchanger and work with Viessmann's ViCare app.

  • Vitodens 050-W: a combi boiler and the most affordable way to get a Viessmann, with built-in WiFi and an LED display with touch buttons.
  • Vitodens 100-W: available as a combi, system or regular boiler. The combi and system versions have built-in WiFi and an LCD display with touch buttons. The regular version connects to the app with an optional WiFi module.

Our guides to combi vs system boilers and what size boiler do I need explain how to choose, or get your fixed price and the quote will recommend a boiler for your home.

Viessmann boiler warranty

Every Viessmann boiler we fit comes with a Viessmann warranty. The length depends on the model and is shown on each boiler above. Viessmann needs the boiler registered within 30 days of installation for the full warranty, and we do that for you.

Viessmann also requires a yearly service by a competent engineer, such as a Gas Safe registered engineer, recorded in the service logbook. Annual servicing isn't something we offer, so book it each year with a Gas Safe registered engineer and keep the paperwork.

What's included when we fit a Viessmann boiler

  • Supply and fitting by a Gas Safe registered engineer
  • Removal of your old boiler
  • A system flush and a magnetic system filter
  • Your manufacturer warranty registered for you
  • A wireless room thermostat as standard with every combi
  • A carbon monoxide alarm, available free with every installation
