Alpha Intec 28x Problems

The Alpha Intec 28x boiler, while popular among homeowners, has raised concerns related to intermittent hot water. Let’s delve into the common issues and potential remedies.

1. Issue: Intermittent Hot Water

A user reported that the hot water from the Alpha boiler is inconsistent. The water does not always heat immediately and, at times, goes off unexpectedly. If it turns off, it may not turn back on for an extended period.

Possible Solutions:

• Replacing the Diaphragm: A commonly suggested solution involves replacing the diaphragm, which can potentially help the boiler system regulate water pressure and heat more consistently.
• Microswitch Replacement: In one scenario, an electrical switch, known as a microswitch, was temporarily replaced. However, it’s worth noting that even after replacing the original microswitch or trying alternatives, the intermittent hot water issue might persist.
• Primary Thermistor Replacement: Thermistors are devices that respond to temperature changes. It’s suggested that for models 240/280, replacing the primary thermistor can potentially resolve hot and cold water flow problems. There’s also the mention of the ‘ch thermistor’, which could be another component to consider replacing.
• Listen for the Microswitch Click: Some professionals can identify issues by listening for the ‘click’ of the microswitch. If there is no click and no hot water, it could be an issue with the diaphragm. A click without hot water often indicates a microswitch problem.
• Debris Check: It’s worth checking for debris that may be obstructing the diaphragm, preventing it from creating enough suction to move the pushrod.

2. Issue: Misidentification of Boiler Model

There’s been some confusion regarding the exact model of the boiler. It’s essential to know the specific model when diagnosing problems, as different models have unique components.

Solution:

Ensure that you’ve correctly identified the boiler model. For instance, while the model 240 and CB 24 are both Alpha boilers, their parts and mechanisms differ significantly. Proper identification will ensure that you’re addressing the issues specific to your boiler type.

3. Issue: Multiple Failed Fixes

It’s common for homeowners to try multiple solutions in succession without resolving the problem. This approach can result in increased costs without finding a remedy.

Solution:

Hiring a trained professional can be invaluable. These experts bring years of hands-on experience and can often pinpoint and address issues more efficiently than a layperson.

In Conclusion:

While the Alpha Intec 28x boiler is a prominent choice for many households, like any appliance, it can have its set of challenges. If faced with intermittent hot water or other issues, it’s beneficial to consider professional advice. Trained professionals have the hands-on experience and knowledge to diagnose problems efficiently and recommend the most effective solutions.
