Glow Worm Compact Combi Boiler Performance and Efficiency
Delivering impressive efficiency numbers, Glow Worm's Compact Combi boiler achieves an A-rating and 92% ErP efficiency that'll help lower your energy bills.
| Model Size | Hot Water Flow Rate | Seasonal Efficiency | Best Suited For |
|---|---|---|---|
| 24kW | 9.9 l/min | 88.6% | 1-2 bed homes |
| 28kW | 11.5 l/min | 88.9% | Larger properties |
You'll get reliable performance with both the 24kW and 28kW models, each designed to match different household needs. The 24kW version is perfect if you're living in a cosy flat or small house, while the 28kW packs extra punch for bigger homes with higher hot water demands.

Glow Worm Compact Combi Boiler Pros and Cons
Smart homeowners weigh both strengths and limitations before investing in a new boiler.
Let's look at what makes the Glow Worm Compact Combi stand out – and where it might fall short.
On the plus side, you'll love how this space-saving unit fits neatly into kitchen cupboards – perfect if you're tight on space.
It's also wonderfully quiet and energy-efficient, with an A-rating that'll help shrink those utility bills.
The 5-year warranty offers peace of mind, too.
However, there are some drawbacks to take into account.
While replacement parts are readily available, they can be pricey.
Also, with only 24kW and 28kW options, it mightn't suit larger homes with multiple bathrooms.
The UK manufacturing and high-quality components are reassuring, but you'll want to factor in potential maintenance costs.
How Does The Glow Worm Compact Combi Boiler Compare To Similar Models From Other Manufacturers?
When shopping for a compact combi boiler, you'll want to see how the Glow Worm stacks up against its competitors. At first glance, its smaller dimensions (626 x 400 x 270 mm) make it more compact than similar models from Worcester Bosch, Vaillant, Ideal, and Baxi.
However, you'll notice some trade-offs. The Glow Worm's maximum 28kW output and 5-year warranty fall short of competitors offering up to 36kW and 10-year warranties.
Its 92-93% efficiency rating is slightly lower than the 94% you'll find in most rival models.
While it doesn't match the premium components of Worcester Bosch or Vaillant, the Glow Worm's lower price point makes it an attractive option if you're working with a tighter budget and don't need the highest power output.
Comparing different boiler output ratings is essential when selecting the right heating system for your specific property type and requirements.
How Much Does A Glow Worm Compact Combi Boiler Cost?

- Magnetic filter for system protection

- 5-year warranty coverage

Glow Worm Compact Combi Boiler Warranty and Service Support
