How Does The Glow Worm Energy System Boiler Compare To Similar Models From Other Manufacturers?
Looking beyond Glow Worm's impressive feature set, you'll want to know how it stacks up against other manufacturers' system boilers.

All three brands achieve the same A-rating for efficiency, though you'll notice the Glow Worm's hot water flow rates (14.4 L/min) are a bit lower than Worcester Bosch and Vaillant (20+ L/min).
The good news? You're getting reliable performance at a more budget-friendly price point.
While it may not have all the bells and whistles of premium models, the Glow Worm Energy delivers dependable heating that won't break the bank.
For a reliable alternative, Potterton boilers offer similar efficiency ratings and competitive features in the same price range.
