Boiler Controls

A Complete Guide on Boiler Controls: Understand More Clearly 

Smart boiler controls make it much easier to program your central heating system while also decreasing energy waste and reducing household bills. However, there are many different types of boiler controls, and there is considerable confusion about how they function and which boilers they are compatible with. So, in this post, you have it: smart boiler controls instructions.

 

What are Smart Boiler Controls? 

Standard controls often give a home basic capabilities such as activation & timer settings for their boilers. Smart gas boiler controls expand on this by providing precise and simple heating schedules via a heating app. Any modifications made in the app are carried out via remote thermostats and smart TRVs. Manual adjustments are also possible for complete flexibility.

 

The Types of Boilers that can use Smart Controls

The smart heating controls you’ll need will depend on the type of boiler you have in your home. The following are the two most common boiler types:

 

Combi – comes from a combination term; this type of boiler system has a separate water tank and provides hot water on demand, making a 1-channel controller ideal.

 

Traditional — Because this boiler system includes a separate water tank, a two- or three-channel controller is necessary.

 

In Detail About Commercial Boiler Controls

 

1: Operating Control

This device is the main boiler control, and it is set to the boiler’s intended operating pressure or temperature. The operating temperature of a hydronic boiler is usually set to 180°. This is commonly set to roughly 2 PSIG (Pounds per Square Inch Gauge) on low-pressure steam systems. When there is a request for heat, this control is an automated reset control, which means it switches the burner on and off.

 

2: Limit Control

This is typically a manual reset control or a boiler control panel that is set higher than the operational control. That is, if the boiler hits the control’s set point, the power to the burner is cut off, and the burner will not work until the temperature inside the boiler falls below the control’s set point and the manual reset button is pressed.

 

A manual reset is used to notify you that the operational control did not switch off the boiler at the stated point. It’s recommended to set the limit control for hydronic boilers 20° to 30° higher than the operational control, 200° to 210°. The boiler may exceed the operating control & turn off the reset control if the setpoint is too near to the operating control set point. Hence, a no-heat call would be a result of this.

 

3: Firing-Rate Control

With a variable-input boiler, such as a low-high-low burner, the firing-rate control is used. This control’s setpoint should be marginally lower than the operational control’s set point. Once the burner hits the specified point of the firing rate control, this control will reduce the burner’s firing rate.

 

How to Have Maximum Efficiency of the Boiler System

Examining your smart thermostats is one of the simplest ways to check that your boiler is operating efficiently. Because these devices sense and monitor room temperature, keeping them away from the boiler, radiators, poorly insulated places, and other electronic devices, as well as providing them with a free flow of air, is critical to their accuracy and reducing energy waste.
