Euroster Q7

Product detailed description

Euroster Q7 - thermostat with a weekly program and backlight (also known as EQ7)

The Euroster Q7 thermostat (also known as EQ7) is a modern, intelligent room thermostat and offers several new and interesting features in its class. It allows setting up to nine different time zones for each day of the week, and any temperature can be selected for each zone. Control of the thermostat has been simplified by using a rotary dial on the outside of the device and an OK button to confirm values and enter the programming menu. All temperature values and settings are clearly shown on the backlit display. Other advantages include temperature changes during the day, and it automatically sets the optimal temperatures at the required time.

Frequently Asked Questions

• How exactly should I choose the output of a EUROSTER condensing boiler? The basis is the calculated heat loss of the heated building (most reliably from project documentation or an energy certificate). If you don't have a project, you can roughly estimate about 60-100 W per m² of floor area for a commonly insulated house built after 2000, or 100-150 W/m² for an older, non-insulated house - the exact figure varies depending on the number of floors, ceiling height, the number and quality of windows, and the building's orientation. An oversized boiler switches on and off more frequently (so-called cycling), which shortens its lifespan and reduces efficiency; an undersized boiler, on the other hand, cannot sufficiently heat the house on freezing days.
• Why is a condensing boiler more efficient than a conventional one? A condensing boiler additionally uses the heat hidden in the water vapor produced when burning gas - in a conventional boiler this escapes unused through the chimney, while in a condensing boiler it is cooled below the so-called dew point, the vapor condenses, and the released heat is returned to the heating circuit. Thanks to this, condensing boilers achieve an efficiency of approximately 105-110% relative to the calorific value of the gas, compared to the usual 85-92% for conventional boilers.
• What type of flue gas exhaust does this boiler need? Most modern condensing boilers are so-called turbo units (with a sealed combustion chamber) and require a concentric or separate flue gas exhaust and combustion air supply routed through an exterior wall or roof - so a functional chimney is not required. You can find the exact type and maximum length of the exhaust (for a diameter of 60/100 or 80/125 mm) in the technical documentation for the specific model, or consult our customer service.
• What does the ErP energy class stated for the boiler mean? This is a mandatory efficiency label for heating appliances under the EU ErP (Ecodesign) directive, similar to the energy labels on refrigerators. Condensing boilers commonly achieve class A, or even higher in combination with room controls (e.g. A+ when using weather-compensated control and a room thermostat).
• Can I install and connect this boiler myself? No. Connection to the natural gas supply, electrical network and flue gas exhaust is by law reserved exclusively for a person with the relevant authorization (most often an authorized service technician of the given brand or a gas appliance inspection technician). After installation, the boiler must be commissioned by the manufacturer's authorized service, which is usually also a condition for the warranty to be valid.
• What about service and warranty? Most manufacturers require a regular annual service inspection by an authorized service provider in order to keep the warranty valid even after its standard expiry (extended warranty with regular servicing is common especially for brands such as Vaillant, Protherm, Viessmann). You can find the exact warranty terms in the warranty card supplied with the boiler.
• What is included in the delivery of this specific product? The exact contents of the package (the boiler itself, possibly a hot water storage tank, room controls and other accessories in the case of a set) are stated in the product name and in its technical parameters above on this page.
