All Vokèra boilers are manufactured to the highest quality with 100% being tested before leaving the factory.
The Sustainable Energy Association of Ireland (SEAI) recommends that you should replace or upgrade your gas boiler if it is more than 15 years old. Even if there are no apparent problems, it’s unlikely to be running above 70% efficiency (new gas boilers are more than 90%) and reliability is likely to be an issue.
