Sealed System Boilers For Heating and Hot Water
The system boiler (often listed as a ‘sealed system’) provides central heating and hot water via a storage cylinder. This means that, unlike with a regular boiler, there’s no need for separate water tanks in the loft of your house.
These models are a great choice for those who have limited space in their loft, or for those living with a large family who wish to use hot water from multiple sources at once.
Glow-worm’s system boilers do not require an expansion tank or feed, freeing up valuable space in your loft and meaning that we can offer a more efficient and cost-saving installation process.
