Alpha E-Tec 28 NX Combi Boiler

Our Thoughts

The Alpha E-Tec 28 NX combi boiler is a great boiler. We like their stainless steel heat exchangers and they have great customer service.

Alpha is currently our second most installed boiler brand. They are great boilers for their price. They might lack some features that more premium brands, like Viessmann, have, but you are paying slightly less as a result.

With their compatibility with OpenTherm we think they will be a great addition to your home. Saving you money on your heating bills compared to older boilers.

Performance 8/10

If you are considering upgrading your old boiler, it’s worth investing in a high-efficiency boiler that comes with a stainless steel heat exchanger. The E-Tec 28 NX combi boiler has an impressive 94% efficiency rate, which can help you save a lot of money in the long run.

Moreover, the stainless steel heat exchanger of this boiler is designed to maintain that high level of efficiency for over 7 years. This is a significant advantage over boilers that use aluminium heat exchangers, which can lose up to 10% of their efficiency over the same period. Therefore, choosing a boiler with a stainless steel heat exchanger can ensure maximum efficiency and significant cost savings for your home heating system.

Quality 7/10

Alpha uses a variety of materials, including brass, copper, composites, and plastics in their boilers. Their heat exchanger is superior to many other boiler models.

Value 8/10

The Alpha E-Tec 28 NX is a great value boiler at a low new boiler cost. Considering the heat exchanger, the price is very good especially compared to similar boilers from Worcester Bosch, for example. This boiler loses a point to the 7-year warranty. The E-Tec Plus NX has a 10-year warranty for longer peace of mind.

Customer Satisfaction 9/10

Alpha Boilers, particularly the E-Tec NX model, have been widely installed across the country and have established a reputation for their dependable performance. While it’s true that no heating system is entirely immune to malfunctions, it’s worth noting that only a small number of issues have been reported among the hundreds of Alpha boilers that have been installed.

At Boilerhut, we understand how crucial it is to provide swift and efficient service if any issues arise, ensuring that your heating system remains reliable and you can have complete peace of mind. Our team is committed to delivering exceptional customer service, and we take pride in our ability to resolve any issues quickly and efficiently.
