What we think of the Glow Worm Ultrapower sxi store boilers

At Boilers Prices,we recommend those with large households where continuous, instant hot water is in high demand to consider Glow-worm’s Ultrapower sxi System Store Boiler. This boiler is available in two models, of 100 lt and 170 lt volume capacity, with an average starting price of £1,350 and £1,460 respectively.

This is one of the most efficient range of Combi boilers you can buy and you can opt for the 10kW model, or the 17kW model. Although they are Combi boilers, they are designed to be able to provide bucket loads of hot water on demand, which means they cater for the larger as well as smaller properties. If having lots of hot water is your thing, then this is a perfect choice.

It has the ability to store hot water (hence the word Store in the product description) inside its casing (which is some 80 litres in the smaller model and some 120 litres in the larger version) which is used before it switches to pure Combi mode. This means that it can cope with heavy hot water demand.

They can both be converted to LPG. The tank inside the boiler obviously demands more space and at 90kg, it is a fair sized unit. This one cannot be hidden away in a kitchen cupboard. But if you want plenty of hot water, then this is the boiler to get.

Getting a Competitive Boiler Quote

We recommend you get a few quotes from local boiler installers and a national installer in order to compare and purchase your new boiler at the best price.

Also make sure your engineer is Gas Safe Registered to ensure your work is carried out safely and correctly.
