There are a variety of boiler brands on the market today, all competing for your custom. To make sure you make the best possible choice, this guide will discus two boiler brands that should be avoided.
It may be the case that you’ve never heard of these brands, and there’s a good reason for that.
What are the worst boiler brands?
Below you find the worst-rated boiler brands in the UK and their common faults. We’ve put them together especially for you so you don’t regret your boiler purchase.
Ferroli is an Italian brand, but they have a base in the UK. Despite this, they have very poor customer reviews and the brand is rated low quality by boiler installers.
The most common complaints are:
- The condensing boilers are not reliable and break down regularly.
- The parts are not easily obtainable. Some customers wait weeks without a working boiler.
- Parts delivery is very slow and unreliable.
- The parts are very expensive or not available at all.
The Vokera range of boilers has been rated poorly for many years. The Vokera Vision 30c Combi Gas boiler has particularly bad reviews. The reviews are usually about:
- Frequent breakdowns.
- Being unable to source parts.
- Low warranty periods, indicating a lack of confidence in their own brand.
- Waiting for hours to speak to customer service.
What are the common problems with Ferroli and Vokera?
Something that the Ferroli and Vokera brands share is that they are cheap. This makes them popular with bargain hunters, but a poor quality boiler can cost a lot of money to repair regularly and will be less energy efficient.
It’s no secret that boiler repairs can be expensive, so investing in a good quality boiler could be more cost-effective. Here are the most common problems:
What are the common problems with a Ferroli boiler?
Leaking: Ferroli boilers are prone to leaking due to the cheaply manufactured shut valves.
Losing pressure: They are known to regularly lose pressure, which could mean the expansion vessel needs to be repressurised.
Heating timer not working: If your heating timer is not working or it is turning itself on at random times, this can be due to the cheap mechanical timer that will need replacing.
Boiler ‘locking out’: This can be a fault with the PCB (printed circuit board). It will need to be replaced to fix the issue.
What are the common problems with a Vokera boiler?
Lukewarm water: Vokera boilers often have problems with the diverter valve, which can get stuck and prevent your water from heating properly.
No water or heating: If you’ve stepped into a cold shower and have no heating, It’s likely a frozen condensate is to blame. In colder months the pipe can freeze as it is not well insulated.
Boiler ‘puffing’: If your boiler is making a ‘puffing’ sound, it may be due to a flue problem. It may have come loose or corroded and will need replacing.
