How Does The Ravenheat CSI 120 Combi Boiler Compare To Similar Models From Other Manufacturers?
Comparing the Ravenheat CSI 120 against major competitors reveals some interesting insights about where this budget-friendly boiler stands in today's market.
While the CSI 120's 89.4% SAP efficiency rating is decent, it falls slightly behind premium brands like Viessmann and Worcester Bosch. You'll find higher-end models offering efficiency ratings above 90%, with Navien pushing 95%.
The 3-year warranty is significantly shorter than what you'll get with brands like Worcester Bosch or Vaillant.
However, the CSI 120's price point of £1,350-£1,850 (including installation) makes it an attractive option if you're working with a tighter budget.
In terms of features, the CSI 120's compact size and fully modulating burner are competitive, though it lacks the smart control capabilities you'll find in models from Vaillant or Navien.
For those interested in premium alternatives, Viessmann boilers offer comprehensive heating solutions with superior build quality and efficiency ratings.
