Length: 1 hour

Statement of Purpose:

This presentation will explore the theory behind gas fired condensing boilers. The following focus topics will be discussed: Heat make-up of natural gas combustion and how it relates to condensing boilers, natural gas – air mixture for the most efficient combustion, latent heat recovery as a product of combustion gas condensation, burner requirements including excess air control to increase boiler operation efficiency, and the relationship between return water temperature and condensing boiler efficiency. In addition, we will elaborate on condensing boilers heat exchanger materials and design requirements.

Length: 1 – 1/2 hours

Learning Objectives:

1. Describe the difference of the B1HA model and the B1KA model
2. Identify the suitable applications for the B1HA model and for the B1KA model
3. List 4 features of the Vitodens 100 boiler and their benefits
4. Identify the preferred method of piping for the Vitodens 100

Length: 1 hour

Statement of Purpose: 

This presentation will explore the combustion process and how it affects condensing boiler performance. The following focus topics will be discussed: The combustion process and how it varies with a change in the fuel, the role of excess air and how it affects boiler efficiency, how combustion is analyzed and what the readings mean, and the relationship between excess air and flue gas dew point. We will also discuss Nitrogen Oxides (NOx), how it is formed, why are concerned and how do we minimize it.

Length: 1 hour

Statement of Purpose: 

Hydronic system performance is highly dependent on the quality of the system fill water, both from an efficiency and longevity standpoint. In this presentation, we will examine the hydronic system and the quality of the water used to fill it. In most applications municipal or well water on site is used to fill the hydronic system. Domestic water may be suitable to consume but due to pH, hardness or other compounds dissolved in the water, the water may have adverse effects on the system. We will look at how these compounds enter the water and the potential problems that dissolved compounds present to the system. Additionally, we will look at the various methods of removing these compounds either in the fill process or through chemical addition. Finally, the various common additives for hydronic systems will be presented.

Length: 1 – 1/2 hours

Objective: This webinar is an overview of the commercial offering of Viessmann boilers. It will cover the features of the boilers that make up the commercial range and an overview of the application of these boiler (Footprint, piping, venting, gas supply, Lambda Pro, wiring, control capability)  to help in your selection process

Length – 1 hour

Statement of Purpose:

In the world of boiler venting there are 4 categories for gas boiler venting and many approaches to venting. In the webinar we will examine the two main categories , category I and IV venting. For each category we will outline the requirements of the vent system. Additionally we will look at vent sizing based on tables and also sizing with vent sizing software. As important as the exhaust gas venting is the combustion air.. We will also examine combustion air requirements, both for sealed systems as well as systems using room air.

Statement of Purpose:

In this webinar we will examine the various approaches to domestic hot water heating methods and the factors that contribute to a wide variety of solutions when it comes to sizing. We will then look at the common methods of providing DHW to an application including indirect water heating using a condensing boiler as the source of heat. For this specific application methods of maximizing performance will be discussed.
