What are the Ravenheat Boilers Fault Codes? A complete list of Ravenheat boiler error codes, including instructions for every model.
Ravenheat are no strangers to manufacturing cost-effective boilers. However, choosing the cheapest option is not always the way to go when investing in a new or replacement boiler. If you’re reading this article, you may be regretting your decision to buy (or the previous homeowner’s decision to buy) a Ravenheat boiler.
This article will help you identify your boiler’s error and fault codes so that you can inform your Gas Safe Engineer what the issue is.

Before we get into the nitty-gritty of your Ravenheat boiler, let’s learn a little bit about Ravenheat as a company.
Founded in 1987, Ravenheat is an independent boiler manufacturer with an annual production capacity of 80,000 units. Ravenheat claims to design and manufacture highly efficient, reliable boilers whilst keeping the costs to a minimum.
After developing their first condensing boiler back in 1996, before they became compulsory in the U.K., Ravenheat is said to have become one of the leading providers in the industry.
Since 1982, Ravenheat has become a member of several trade bodies and associations, including becoming a member of the HHIC since it formed in 2007, becoming a member of the All-party Parliamentary Group for Energy Studies since 1982, and a member of the Institute of Domestic Heating & Environmental Engineers since 1991.
Ravenheat has four ranges of boilers available to purchase, the CS and CSI range, as well as the HE and HE Compact range. Their warranties and guarantees range from between 2 to 10 years. However, this is dependent on your boiler being installed by a certified Gas Safe Engineer and your warranty being activated upon purchase, otherwise, your warranty is invalid.
If you would like more information about the difference between a boiler warranty and a guarantee, we also have a blog that covers this.
Although you may not feel like there are any benefits of having a Ravenheat boiler, according to Ravenheat, there are some. These include:
- Low Energy Use – Energy Band A
- Whisper Quiet Operation
- 5 Year Guarantee included
- Compact & Light
- Low Emissions Nox Class 5
- Solar Compatible
While Ravenheat claims to be “no strangers to manufacturing reliable boilers”, what do customers think about Ravenheat boilers?
If your search for Ravenheat in Trustpilot, for a claimed leading provider, the results are pretty worrying. With only 2.3 stars out of 5 and only 10 reviews and a huge 60% of these being negative, you understandably start to question the reliability and efficiency of these boilers.
When comparing these ratings to well-known boiler brands such as Worcester Bosch, who have over 26k reviews on Trustpilot and 4.6 stars out of 5 and Baxi, that have over 27k review and a score of 4.5 stars, you would be better off purchasing a new or replacement boiler with a boiler manufacturer that you can rely on a bit more for build quality and customer service.
If you suspect an issue with your Ravenheat boiler, we have provided a list of their fault/error codes that could help you to identify the issue and potentially point it out to your Gas Safe Engineer.
