Vaillant Ecotec Pro 24 Boiler Details

The Vaillant ecoTEC pro 24 boiler is designed for high efficiency and user convenience, featuring an intuitive operating concept. Its clear basic display provides immediate feedback on current heating flow temperature, system filling pressure, and the boiler's active operational status. Essential control elements, including an on/off button, a dedicated fault clearance key, and simple operating buttons, make managing the boiler straightforward. Integrated symbol indicators for burner activity, hot water generation, heating mode, Comfort mode, and maintenance alerts ensure users are always well-informed about the system's performance and needs.

Beyond its core functions, the ecoTEC pro 24 offers several intelligent operational modes. The Comfort mode stands out by providing instant hot water at the desired temperature, eliminating any waiting time. For warmer periods, the versatile Summer mode allows users to switch off the central heating while maintaining efficient domestic hot water production. An electronic restart lockout, known as the anti-cycling time, prevents the burner from frequently switching on and off, which significantly extends the lifespan of the appliance and contributes to overall energy savings.

Safety is paramount in the design of the ecoTEC pro 24. It incorporates robust overheating protection that preemptively shuts down the system before any critical temperatures are reached. A sophisticated, built-in frost protection device actively monitors boiler water temperatures, engaging the pump and, if necessary, the burner to heat circulating water to approximately 30°C if the temperature drops below 5°C, safeguarding against freezing damage. The boiler also features continuous water pressure monitoring, signaling low pressure conditions (e.g., F.22 fault) and automatically ceasing operation if pressure becomes critically low.

This model is engineered for exceptional energy efficiency and minimal environmental impact. As a condensing boiler, it achieves an impressive 30% efficiency of 109.4% and holds an ErP A/A rating for both heating and domestic hot water. Recognized as an Energy Saving Trust Endorsed Product, it is proven to lower running costs and reduce carbon emissions. The ecoTEC pro 24 also meets stringent environmental standards with its low NOx Class 6 rating. Its high efficiency design results in very low heat loss from the casing, so compartment ventilation is not required.

Constructed with premium quality components, including a brass diverter valve and a patented stainless steel main and secondary heat exchanger, the ecoTEC pro 24 guarantees superior heat transfer, reliability, and long-term performance. Its compact dimensions (720x440x338 mm) facilitate flexible installation in various spaces. Maintenance is simplified due to an accessible internal layout, allowing all key components to be replaced conveniently from the boiler front. Furthermore, the boiler has been awarded Quiet Mark accreditation, certifying its remarkably quiet operation, making it suitable for peaceful home environments.

Frequently Asked Questions (FAQs)

Can't find the answer you need? Here are some frequently asked questions about the Vaillant Ecotec Pro 24 Boiler, and we answer them below.

How do I switch on my Vaillant ecoTEC pro 24 boiler?

Press the on/off button located on the control panel. The basic display will then appear, indicating the product is active.

What does it mean if the display shows 'F.22'?

F.22 indicates a safety switch-off due to low water pressure in the heating system. You will need to fill the heating installation to the recommended pressure (0.10 to 0.20 MPa or 1.0 to 2.0 bar).

How do I adjust the heating flow temperature?

Press the "circle" button, then use the '+' or '-' buttons to set your desired heating flow temperature. Confirm the setting by pressing the "circle" button again.

What is Comfort mode and how do I activate it?

Comfort mode ensures immediate hot water at the required temperature without waiting. Press the "hot water tap" button, then the "circle" button. "Comf. on" or "Comf. off" will flash; use '+' or '-' to select "Comf. on" and confirm.

How often should my boiler be serviced?

An annual inspection and maintenance by a competent person is recommended to ensure optimal performance, safety, and longevity of the product. The Benchmark Checklist should be completed each year.

What should I do if I smell gas in my home?

Immediately avoid rooms with gas smell, open doors and windows for ventilation, do not use naked flames or electrical switches, close the emergency control valve, warn others, and evacuate the building. From outside, notify the gas supply company or National Grid.

Does the ecoTEC pro 24 have frost protection?

Yes, the boiler has a built-in frost protection device that operates the pump and can activate the burner if the boiler water temperature falls below critical levels (e.g., 5°C) to prevent freezing. This function requires the boiler to be switched on and connected to power.

What is the maximum domestic hot water output temperature?

The hot water output temperature range is adjustable from 35 to 65 °C.

What if my boiler displays an 'F.28' fault?

F.28 indicates a start-up failure where ignition was unsuccessful, possibly due to gas supply issues. Press the fault clearance key for one second to attempt re-ignition. If the fault persists after three attempts, contact a competent person.

Can I install the boiler in a bathroom?

Yes, the boiler may be installed in a room containing a bath or shower, but it must only be installed in zones 2 or 3 in accordance with the current I.E.E. Wiring Regulations and Building Regulations (GB) or I.S.813 and ETCI rules (IE).

How do I check the heating system's filling pressure?

Press the "circle" button twice. The display will show the current, minimum, and maximum filling pressures. The ideal range is 0.10 to 0.20 MPa (1.0 to 2.0 bar).

What kind of water should be used for the heating system?

The heating installation should be filled with suitable heating water, which should be checked for quality (pH, hardness, absence of magnetite) and treated with appropriate inhibitors if necessary, according to national regulations and technical rules.

What does the 'S.04' status code mean?

S.04 indicates that the burner for heating mode is activated, meaning the boiler is actively producing heat for your central heating system.

What is the boiler's ErP efficiency rating?

The Vaillant ecoTEC pro 24 has an ErP efficiency rating of A for both heating and domestic hot water.

Can I temporarily switch off the boiler without draining the system?

You can temporarily decommission the product by pressing the on/off button and closing the gas stopcock (and cold water stop valve for combination products), provided no frost is expected, to keep frost protection devices active.
