FlexicomHigh efficiency condensing boiler Compact, flexible and hard wearing
Compact and flexible The thing about UK houses is that in a lot of cases there isn’t a lot of space for things like boilers. Lets face it you would rather have the extra cupboard space to store the multitude of “stuff” that a family gathers over time. That is exactly why the Flexicom was developed.
The Flexicom is compact enough to fit in a standard kitchen cupboard and was the first high efficiency boiler in the UK with a direct rear flue, meaning that if you are looking to remove a standard efficiency boiler with a direct rear flue, the Flexicom will easily replace it.
Available as a combi, open vent or a sealed system boiler with a wide range of outputs, the Flexicom is recommended by the Energy Saving Trust with a SEDBUK A and NOx class 5 rating.
Robust and simpleThe Flexicom provides a quick and simple installation with no need to remove the front casing during installation thanks to the pre-fixing jig, upward piping frame and the drop down connection block. The aluminium heat exchanger also has wide waterways which enable the Flexicom to easily cope with system debris that has built up over time - ideal for retro fit.

Ultrapower sxiAdvanced system storeComplete heating system in one box
Imagine if you could fit a complete heating system that provides endless heating and hot water for a large household in one floor standing appliance about the size of a small fridge freezer, it seems like an extraordinary feat of engineering, but that is exactly what the Ultrapower does.
One of the most efficient boilers in the UK as rated by SEDBUK, the Ultrapower provides endless hot water on demand through an innovative storage system with fast reheat times and combi back-up, all within a single appliance that fits in an airing cupboard.
Endless hot water on demand The innovative shift load storage system of the Ultrapower sxi generates hot water whenever a tap is turned on. By drawing on the internal storage system at the same time it can rapidly deliver the performance of a 170 litre cylinder.1
The Ultrapower sxi also utilises a much smaller hot water cylinder than a conventional system boiler, but because the boiler recharges the cylinder as the hot water is being drawn off. This means the Ultrapower sxi provides the same hot water performance as a much larger indirect cylinder.
Complete control atthe touch of a button In addition to the impressive hot water delivery the Ultrapower sxi has an inbuilt digital programmer providing 7 day or 24 hour, single or two channel control for the central heating and hot water pre-heat function which provide as much or as little flexibility as needed.

Hot water performanceThe Ultrapower sxi heats the water stored in its cylinder directly, which makes it far more compact than an indirect cylinder.
Once the hot water stored has been depleted, the boiler operates as a normal combi, which means you never run out of hot water.
Quick reheat timesThe Ultrapower sxi recharges the cylinder as hot water is being drawn off, resulting in much faster reheat times compared to that of a conventional indirect cylinder.

Xtramax HEHigh efficiency storage combiSimplicity of combi with the flow rates of a sealed system With highly insulated modern houses, often our hot water demand hugely outweighs our heating requirements (even with the UK climate). The Xtramax is a wall hanging storage combi that can deliver an endless supply of hot water. Its innovative internal store lets you draw hot water from 2 or 3 taps at the same time and at much higher flow rates than you would normally expect from a combi.
Rated SEDBUK A with a NOx class 5 rating the Xtramax HE can generate up to 200 litres of hot water rapidly with a recovery rate of just 4 minutes.

Controls and timersOnce you have taken the time to choose your new Glow-worm boiler it soon becomes the reliable white box under the stairs, in the kitchen cupboard or in the airing cupboard.
However, the controls become part of your everyday life. It is extremely important that you pair your appliance with easy to use controls that enhance your heating system.
Glow-worm provide a wide range of controls designed for different homeowner needs, all with user friendliness at the heart. With simple push button controls, large screens and neat designs which are easy to use and look at home in any UK house.
All Glow-worm controls use Ebus protocol to talk directly to your Glow-worm boiler, enabling them to talk intelligently to each other. This creates more efficient heating systems that deliver savings on household energy bills and add 2% to SEDBUK values in the Code for Sustainable Homes when used for room (load) or weather compensation.
Intelligent room control explainedIntelligent room control is a simple method of controlling the flow temperature of water to the central heating system based on the temperature measured in the room.
As the temperature approaches the desired set point, the Glow-worm Climastat or Climapro/RF begins to lower the flow temperature of water supplied to the central heating system (radiators).
A lower flow temperature means that the boiler operates more efficiently in, or closer to the condensing mode. Energy costs are then reduced and a more stable and comfortable room temperature is achieved.
Weather compensation explainedWeather compensators work by measuring the temperature outside the property and adjusting the flow temperature from the boiler to the radiators accordingly. Meeting the needs of the actual daily heat demands of the property. The colder the outdoor temperature, the hotter the flow temperature to the radiators, conversely as the weather improves and becomes warmer outdoors, the cooler the flow temperature to the radiators. This ensures that the boiler is operating as efficiently as possible whilst still keeping the temperature in the house comfortable.

Fully compatible with all Glow-worm boilers, these handy accessories help solve pluming and condensate issues that can be faced when installing modern condensing boilers.
Plume Management KitThis clever accessory exhausts plume further away from the duct, reducing the visual impact of the vapour trail. The simple piping kit fits neatly onto the horizontal flue and can be extended to a maximum of 6m in length, fitting easily round ledges and other obstacles to achieve minimum clearance levels required on installations.
Plume Deflector KitA useful accessory takes the hassle out of flue gas termination by diverting plume left, right or upwards away from problem zones such as adjacent properties or walk ways.
Available in black or white, the Plume Deflector Kit can be installed quickly and simply onto a horizontal flue instead of the standard terminal end piece during or after installation.
Accessories:Plume & condensate solutions

Condensate PumpTo solve problems associated in locating a suitable outlet to drain away condensate from the condensing boiler, the Glow-worm Condensate Pump collects the condensate from the boiler and pumps it into the waste system.
The smallest available in the UK, the Glow-worm Condensate Pump operates at maximum efficiency with the reservoir pump discharging the condensate in one go when the fill level is reached, rather than as a continuous operation.
Ridge Tile TerminalThe Ridge Tile Terminal accessory is designed to make the roof finish look neater and less obtrusive. Available in a black enamel finish, the ridge tile accessory can be fitted to purpose designed flue outlet ridge tiles and provides a quick and easy design solution.
