The Glow-worm Energy System range of boilers uses a separate storage cylinder for hot water so you'll need to find space for this in an airing cupboard.

To discover whether the Glow-worm Energy range is likely to be the best boiler for your home take a look at our full review, which also reveals what heating engineers think of Glow-worm gas boilers and how reliable they are.
