The Vaillant gas boiler VKS 23 E is a compact and efficient heating system designed for small to medium-sized homes. It is a wall-mounted condensing boiler that runs on natural gas, providing both heating and hot water. The VKS 23 E is known for its high energy efficiency, low emissions, and quiet operation. It also features advanced technology for optimal performance and reliability. **

To determine if the gas boiler set to E (Electric) is hot enough, you should check the temperature setting on the boiler. Typically, the recommended temperature for hot water in a boiler is around 120-140 degrees Fahrenheit. If the temperature setting is within this range, then the boiler should be hot enough. However, if you are experiencing issues with the hot water supply, it may be a sign that the boiler is not functioning properly and may require maintenance or repair. **

A boiler is a closed vessel in which water or other fluid is heated. The heated or vaporized fluid exits the boiler for use in various processes or heating applications. Boilers can be fueled by various sources such as natural gas, oil, coal, or electricity. They are commonly used in residential, commercial, and industrial settings to provide heating and hot water. **

I'm sorry, I am not able to physically inspect the boiler to determine if it is broken. It would be best to have a professional technician inspect the boiler to determine if it is broken or not. If you are experiencing issues with your boiler, it is important to have it checked by a qualified professional to ensure it is functioning properly and safely. **

To fill water into the Vaillant VC 196 E boiler, you will first need to locate the filling loop, which is usually a flexible hose with a valve at each end. Connect one end of the filling loop to the cold water supply and the other end to the boiler. Open both valves to allow water to flow into the boiler until the pressure gauge reaches the recommended level, usually around 1-1.5 bar. Once the correct pressure is reached, close the valves and remove the filling loop. Remember to check the pressure gauge regularly to ensure the boiler is operating efficiently. **

The power consumption of a gas boiler or combi boiler can vary depending on the model and size of the unit. On average, a gas boiler typically consumes around 2,000 to 2,500 watts per hour when in use. This translates to approximately 48 to 60 kilowatt-hours of electricity consumption per day if the boiler is running continuously. It's important to note that energy-efficient models may consume less power, resulting in lower electricity bills. **

The main difference between a conventional boiler and a condensing boiler is their efficiency in utilizing fuel. Conventional boilers typically operate at around 70-80% efficiency, while condensing boilers can achieve efficiencies of 90% or higher. This is because condensing boilers are designed to capture and reuse heat that would otherwise be lost in the flue gases. As a result, condensing boilers are more environmentally friendly and can help homeowners save on energy costs in the long run. **

Liquids with higher viscosity, such as vegetable glycerin (VG), tend to ensure a longer lifespan for coils. This is because thicker liquids do not vaporize as quickly as thinner liquids, reducing the likelihood of the coils burning out. Additionally, liquids with lower levels of sweeteners and additives also contribute to a longer coil lifespan, as these ingredients can gunk up the coils and cause them to degrade more quickly. Therefore, choosing e-liquids with higher VG content and minimal additives can help extend the lifespan of coils. **
