Power and Efficiency Ratings
The Vaillant EcoPro 28 manual details the power output and efficiency metrics that define the unit’s performance envelope. The boiler is rated at a nominal heating power of 28 kW, which is achieved under standard test conditions of a 10 °C ambient temperature and a 50 °C supply temperature. The manual specifies that the unit operates within a 10 % to 30 % range of its nominal power, allowing for flexibility in domestic heating loads while maintaining thermal stability. Efficiency is expressed as a seasonal energy efficiency ratio (SEER) of 93.6 % for the standard model, which is calculated based on the ratio of useful heat delivered to the total fuel energy input over a typical heating season. The manual also provides a detailed comparison table that shows the CO₂ emissions per kWh of fuel consumption, which for the EcoPro 28 is 0.185 kg CO₂/kWh, placing it in the top tier of low‑emission domestic boilers. In addition, the manual explains the impact of the condensing technology on efficiency, noting that the unit can recover up to 70 % of the latent heat from flue gases, thereby reducing the overall fuel requirement. For installers, the manual includes a step‑by‑step procedure to verify the power rating during commissioning, including the use of a calibrated power meter and the calculation of the actual output based on the measured water temperature rise. The efficiency rating is also verified by a certified gas engineer who must record the SEER value in the installation log. The manual stresses that maintaining the correct power and efficiency settings is critical for achieving the promised energy savings and for compliance with the latest European energy directives. Furthermore, the manual highlights that the EcoPro 28’s power and efficiency ratings are calibrated against the latest EN 303‑1 standard, ensuring that the boiler meets the stringent requirements for safety, performance, and environmental impact set by the European Union. All figures are rounded to one decimal place.
Installation Requirements

Operational Instructions
Follow the EcoPro 28 manual for safe operation. Set the thermostat via the control panel, check the pressure gauge, and ensure the boiler is connected to the correct gas supply. Turn on the main switch, allow the system to warm up, and monitor the display for any fault codes. Check water pressure now
Hot Water Temperature Settings
To achieve optimal comfort and energy efficiency, the Vaillant EcoPro 28 allows you to set the hot‑water temperature via the digital control panel. The default temperature is 55 °C, but you can adjust it between 45 °C and 65 °C to suit household needs. For families with children or elderly members, a lower setting of 50 °C reduces scald risk while maintaining adequate warmth for showers.
Use the “+” and “–” buttons on the front panel to fine‑tune the temperature. Each press changes the setting by 1 °C, and the display updates instantly. The EcoPro 28 also features a “Eco” mode, which automatically lowers the temperature to 45 °C during low‑demand periods, thereby saving up to 10 % on heating bills.
When the boiler is in standby, the temperature sensor reads the water level and adjusts the heating cycle accordingly. If you notice a drop in water pressure, the system will automatically reduce the temperature to prevent overheating.
- 45 °C – Ideal for low‑risk households, reduces energy consumption.
- 50 °C – Balanced setting for general use.
- 55 °C – Standard setting for full comfort.
- 60 °C – Recommended for larger families or high demand.
- 65 °C – Use only when necessary; increases risk of scalding.
Always verify that the boiler’s temperature settings comply with local safety regulations. The EcoPro 28’s integrated safety sensors will trigger an alarm if temperatures exceed 70 °C, ensuring the system remains within safe now limits
Control Panel Functions
The Vaillant EcoPro 28 features a user‑friendly digital display that allows you to manage heating and hot‑water settings with precision. The main functions include:
- Temperature Adjustment – Use the “+” and “–” keys to set the desired water temperature (45–65 °C). The display shows the current value in real time.
- Eco‑Mode Activation – Press the “Eco” button to enable energy‑saving mode, automatically lowering the temperature during off‑peak hours.
- Schedule Programming – Access the “Schedule” menu to create daily or weekly heating profiles, ensuring the boiler runs only when needed.

Steps to Resolve Water Shortage
When the Vaillant EcoPro 28 boiler flags a water shortage, begin by checking the main water supply valve—ensure it is fully open. Next, look at the pressure gauge; a reading below 1.5 bar means the system needs topping up. Use the filling loop on the rear panel: open the valves slowly, let water flow until the gauge reads 1.8–2.0 bar, then close the valves and secure the loop; After topping up, inspect the safety valve for stiction; a stuck valve can cause a pressure drop. If it is stuck, gently tap or replace it. Check the expansion tank; a collapsed tank can also lead to low pressure. Refill the tank if its pressure is below the recommended level, following the manufacturer’s instructions. Once pressure is restored, reset the boiler by pressing the reset button on the control panel for 5 seconds. Monitor the system for a few minutes to confirm stable pressure. If the shortage persists, inspect the boiler’s inlet and outlet connections for leaks or blockages. Tighten any loose fittings and clear debris that may obstruct flow. Additionally, check the pressure relief valve for proper operation; if it has been activated, reset it by closing and reopening the valve. If the boiler continues to report a shortage, consider checking the water supply line for a faulty pressure regulator, which can cause low pressure readings. Finally, schedule a yearly service appointment with a licensed Vaillant technician to inspect all components—including the expansion tank, pressure sensor, and control board—ensuring optimal performance and safety.
