Vaillant Ecotec Pro 28 Boiler Details

The Vaillant Ecotec Pro 28 boiler is a highly efficient, wall-hung heat generator designed for both closed heating installations and domestic hot water generation. It is built with user safety and operational convenience at its core, featuring a robust set of controls and internal safety mechanisms to ensure reliable performance. The product is certified for use in Great Britain and Ireland, adhering to local gas types and regulations.

Operation is intuitive, centered around a clear display and tactile control elements. Users can easily adjust heating flow and hot water temperatures, with visual feedback on the boiler's current status and any active functions. The system also supports connection to external controllers, offering enhanced flexibility for managing heating and hot water demands.

A key comfort feature is the Comfort mode, which pre-heats water to the desired temperature, eliminating waiting times for hot water. This intelligent design enhances the user experience, providing immediate access to hot water when needed, and is a hallmark of Vaillant's commitment to convenience.

The boiler incorporates comprehensive safety devices. It includes an advanced overheating safety system that anticipates and prevents lockout, an integrated frost protection function that activates the pump and burner at low temperatures, and a condensate drain blockage detection system to prevent damage. In the event of an electrical supply failure, the boiler is designed to resume normal operation upon power restoration.

For maintenance, the Ecotec Pro 28 is designed for accessibility, allowing most components to be replaced from the front. The product also carries prestigious accreditations, including the "Energy Saving Trust Endorsed Product" brandmark, highlighting its energy efficiency. It is a full member of the Hot Water Association and a licensed member of the Benchmark Scheme, ensuring high standards of installation and performance.

Notably, the boiler has received Quiet Mark accreditation, signifying it as one of the quietest boilers available. This commitment to reduced noise levels contributes to a more peaceful home environment. Its wide modulation range of up to 1:5 allows it to adapt perfectly to varying system demands, optimizing efficiency and performance in all situations.

Frequently Asked Questions (FAQs)

Can't find the answer you need? Here are some frequently asked questions about the Vaillant Ecotec Pro 28 Boiler, and we answer them below.

How do I turn on the Vaillant Ecotec Pro 28 boiler?

Simply press the on/off button on the boiler. The basic display will then appear, indicating that the product is switched on.

How do I set the heating flow temperature?

Press the left-hand selection button (marked with a heating symbol). The current target value for the heating flow temperature will appear, which you can adjust using the +/- buttons and confirm.

How do I set the hot water temperature?

Press the right-hand selection button (marked with a tap symbol). The set hot water temperature will flash. Adjust it using the +/- buttons and confirm the new setting.

What is Comfort mode and how do I switch it on or off?

Comfort mode provides hot water at the required temperature immediately, without waiting for it to heat up. To activate, press the right-hand selection button twice. The display will show "Comf. on" or "Comf. off". Use the +/- buttons to toggle and confirm.

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

Press the left-hand selection button twice. The display will show the current filling pressure, along with the minimum and maximum permitted ranges. The pressure should typically be between 1.0 and 2.0 bar when cold.

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

Immediately avoid rooms with the smell, open windows for ventilation, do not use naked flames or electrical switches. Close the main gas isolator and the gas isolator cock on the boiler if safe to do so. Warn others, leave the building, and notify the gas supply company or National Grid from outside.

What does fault code F.22 indicate?

Fault code F.22 signifies a safety switch-off due to low water pressure. This means there is no or insufficient water in the product or the water pressure is too low. You will need to fill the heating installation to the correct pressure.

How often does the Ecotec Pro 28 boiler require maintenance?

An annual inspection by a competent person is recommended to ensure the product's safe, reliable, and long-lasting operation. The Benchmark Checklist, provided with the boiler, should be completed after each service.

Does the boiler have frost protection?

Yes, the appliance has a built-in frost protection device. If the boiler water temperature falls below 5 °C, the burner will activate to heat the circulating water to approximately 30 °C to prevent freezing, provided the unit is switched on and connected to power.

How do I switch off heating mode for summer?

To switch off heating mode without affecting hot water generation, press the left-hand selection button and set the heating flow temperature to "Off" using the +/- buttons. Confirm the change, and the summer mode symbol will appear on the display.

What kind of water quality is required for the heating system?

Vaillant recommends checking the pH value of the heating water (ideally between 8.2 and 10.0 at 25°C) and the water hardness. For optimal performance and to prevent material damage, suitable heating water quality and appropriate treatment with approved inhibitors are crucial.

What happens if the condensate drain becomes blocked?

As a safety feature, the boiler will stop working if the condensate drain becomes blocked. During freezing conditions, this may be due to ice forming in the external drain. Warming the pipe can release ice, allowing the boiler to restart after pressing the reset button.

What does the 'Maintenance required' symbol mean on the display?

If a wrench symbol appears on the display, it indicates that maintenance work is required. The product is not in fault mode and continues to operate but needs to be inspected by a competent person. If water pressure is also flashing, add more heating water.
