boiler servicing in Theydon Bois: questions we get a lot
Are Glow-worm and Vaillant the same?▾
Same parent group, often shared componentry, but Glow-worm sits at a lower price point with shorter warranties. Good value for rental properties.
How often should a boiler be serviced?▾
Once a year. It's almost always required to keep the manufacturer's warranty valid, and it catches small issues before they become breakdowns.
How long does a service take?▾
Usually 45–60 minutes for a domestic boiler in normal condition.
