The Pros and Cons
As you might have caught on by now, the Glow-worm Energy 25 C boiler is a good choice when it comes to heating if you have a small home. It is also a great way to save money and reduce your carbon footprint, whilst you’re at it. In addition, the boiler has an average capacity and is simple to repair if needed. However, there are certain disadvantages – especially when you have a larger home.
If you prefer your boilers to be ‘home-grown’ and you are in the UK, then you’ll be pleased to know that Glow worm builds it’s Energy 25C combi boiler in it’s Belper (England) factory. Although Grundfos pumps are installed with the boiler and are a Danish company, but they do provide a high-efficiency modulation included within the Energy combi boiler, which lowers operating costs by adjusting to the actual demand for heating and hot water.
- ErP A rated combi boiler (94% efficiency).
- It can be fitted in numerous places – such as kitchen cupboards – because of its small footprint.
- Flue options at the back provide for greater design flexibility.
- Quiet Mark signifies that householders can enjoy ultra-quiet operations.
- You should be able to save money in the long term thanks to its high-efficiency level.
- The manufacturer’s warranty is 7 years, but you can get up to 10 years.
It’s a good choice for people who live in small flats, due to the boiler’s diminutive size. The flow rate of 12.1 liters per minute is enough for a one or two-bedroom house to be heated. This means that a family of three to four will be able to take showers and baths with no problems.
The Glow-worm Energy 25C can be used in smaller homes, but it may not be enough to keep you warm if you live in a larger household. If you have a four-bedroom house, for instance, then you may want to explore a boiler model with a larger capacity. Other drawbacks include:
- Insufficient water flow to allow for more than two showers simultaneously.
- Extended warranties of up to ten years are not automatically available (unless installed by a Glow-worm Club Energy Installer, which at Boiler Choice we are!).
- Programming the controls can be challenging at times.
The Glow-worm Energy 25C combi boiler is a great choice to replace your old boiler. It’s perfect for small homes and apartments, as it takes up little space. It has an aluminum heat exchanger designed to last longer – and save you money, at the same time.
In addition, it includes a 10-year manufacturer’s warranty. However, don’t expect much if you have more than two bathrooms and a busy household, given its limited heating capacity and flow rate.
