Glow-Worm Combi Boilers Prices Range – Compact, Neat & Value For Money

Combi boilers generally work by taking cold water straight from the mains supply and heating it as required, which removes the need for separate water storage tanks. Glow-worm combi boilers offer a fantastic level of high-efficiency heating performance, and the Flexicom boilers are the only range of gas boilers in the UK with a direct rear flue option. This means that you can install a Flexicom combi boiler almost anywhere. Extensive flueing options are a feature of all new Glow-worm boilers, allowing for increased flexibility when fitting. Glow-worm combi boiler prices range from £550 to £1,555 and come in various sizes with a range of flow rates and outputs.

Glow-Worm Regular Heat Only Boilers Prices Range – Traditional & Practical

Regular heat only boilers (often referred to as conventional or open vented boilers) tend to be used in more traditional central heating systems and are ideal replacements if this type of system is already installed in your home. Working on the basis of ‘heating only’, a heat only boiler requires additional storage tanks for hot and cold water. Unlike the combi boiler system, hot water flow rates tend to be higher as hot water is already stored in the hot water cylinder. This enables multiple taps to be used at the same time but it takes up more space than modern systems. Glow-worm regular heat only boilers range from £623 to £1,004 with varying outputs (depending on the size of the property).

Suitable for different lifestyle and properties, the Glow-worm regular heat only boiler range includes the following options:

HEAT ONLY GAS BOILER SERIES	SIZES	SIZE OF HOME	PRICE
Glow-worm Flexicom hx Regular	24 – 35kW	Small, medium and large-sized homes with more than one bathroom	£622.80 – £1,003.64
Glow-worm Energy Regular	12 – 30kW	Small, medium and large-sized homes with more than one bathroom	£780 – £900
Glow-worm Ultimate₃ Regular	25kW	Small and medium-sized homes with more than one bathroom	£830

Glow-Worm System Boilers Prices Range – Reliable, Neat & Quick To Install

Glow-worm system boilers are highly efficient and come in a range of sizes with varying flow rates and outputs. Prices range from £625 to £1,789.

These days, Glow-worm is dedicated to offering customers dependable and high-efficiency products that are built at state-of-the-art production facilities in Derbyshire. As a leading boiler manufacturer and one of the first to produce a condensing boiler, it came as no shock when the brand was acquired by the incredibly popular Vaillant Group in 2001. But what do customer and engineer reviews say? To help you choose the most reliable brand of boiler, we’re going to take a look at what the nation has said about Glow-worm.

Average Which? Score

After reading mostly positive reviews on Trustpilot, we’re surprised to learn that Glow-worm has an overall Which? score of 54%.
