FAQ

1.               What is the Heating Box?

               The Heating Box is an integrated heat transfer control station that accepts hot water from a heat source and then re-directs it as required to provide domestic hot water and/or heat to hydronic applications. It works to direct hot water traffic in the most efficient and effective way  to satisfy household demand. The Heating Box simplifies the design and installation of any combination domestic hot water and hydronic space heating system.  It facilitates the application of single source heating appliance, such as tankless water heater, with hydronic space heating and offers the benefits of design time savings, easy installation, space savings and energy savings. The Heating Box is prefabricated with the highest quality components and guided by the computer precision control necessary to perfect domestic hot water and hydronic delivery.

 

2.                What applications can I use with the Heating Box?

 

              The Heating Box can be used with any type of hydronic heating application including radiant in-floor heat, baseboard, hydronic air handler, snow melting system, spa/pool water re-heating system and towel warmer etc.

 

3.                What types of heat sources can I use with the Heating Box?

 

              You can use any type of heat source in conjunction with the Heating Box:  boiler, tank water heater, tankless water heater, electric water heater, solar, & much more.

 

4.                What factors do I need to consider selecting a heat source appliance?

               The Heating Box is equipped with a high head pump that will achieve a certain flow rate at given pressure drop from the heat source. It is recommended to cross reference the Heating Box¡¯s pump curve against the possible heat source¡¯s pressure drop curve that would determine the system¡¯s flow rate and BTU delivery.  It is important to select an appliance that will meet your BTU demand.

5.                How does the Heating Box differentiate between the domestic hot water supply and the space heating supply?

          The Heating Box is equipped with a sensor that prioritizes the domestic hot water supply with thermostatic mixing valve to ensure maximum domestic hot water supply at safe and steady temperature.

 6.                Does the Heating Box work with application like Snow Melt System with glycol in water?

           The Closed-Loop System has two built-in heat exchangers to separate water flow between domestic and space heating.  It is ideal for applications with the media in the water that is harmful for people to consume.  For the glycol system, it is recommended for no more than 40% of glycol.   

 7.           What is the max BTU output of the Closed-Loop System?

            It depends on the heat source and design delta T you are using with the Heating Box.

 

8.               How many zones can the Heating Box control?

 

             The standard area size we recommend to use for the Heating Box is maximum around 2000 sq ft with most tankless gas water heater.  However, it can vary depending on the heat source and its output temperature and the flow.  Please contact us when your area specification exceeds our recommendation. 

 

9.                Can I use cascaded heat source system with the Heating Box?

 

               Yes, presumably domestic hot water demanded over average or/and required high flow facility and applied to heating box or multi heating box application, one have to know first how big space size and what kind space heating system intend to use such as radiant heating or air handler system.

 

10.             Do you have a certification for my area?

              The Heating Box is certified by CSA (Canadian Standard Association)

 

11.            Is there a feature of diagnostics built in to the Heating Box?

 

             No, however our website and installation manual has a very detail troubleshooting guide that will guide you through any possible problems you might run into.

 

12.            Where can I buy this product?  Can I buy it directly from you?

 

              You can purchase the Heating Box from any plumbing wholesaler in your area.  If you need to find a wholesaler in your area, give us a call.

 

13.             What is your lead time?  Can It be shipped by UPS?

 

              KyungDong America Inc is located in Southern California.  The Open-Loop System is 65 lbs and the Closed-Loop System is 95 lbs.  Both can be shipped by UPS but it prefer to be sent by a truck on the Close-Loop System.

 

14.             Do you have a service technician in my area?

 

              No, contact to us immediately and we can walk you through with any problems you might have.
