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 heating system. It facilitates the application of single source heating appliances, like tankless water heaters, with hydronics 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 hydronics delivery.

2. What kind of space heating can be used with the Heating Box™?
The Heating Box™ can be used with any type of heat source for any type of hydronic heating application including radiant in-floor, radiant baseboard, hydronic air handlers, snow melting systems, spa and pool heating, towel warmers, and etc.

3. How can the Heating Box™ be used with snow melting systems or other non-portable applications when it also delivers domestic hot water?
By separating the flow though its built-in heat exchanger, the "closed loop" model of the Heating Box™ makes snow melting, spa heating and pool heating (and any other "closed loop" applications) safe and easy. For glycol systems, AQ Energy recommends a maximum of 40% glycol.

4. How can 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 by modulating a computer controlled valve to ensure maximum domestic hot water supply at a safe and steady temperature.

5. What is the recommended temperature that the heat source (such as a water heater) is set at?
To maximize the heat transfer potential, the Heating Box™ requires the heat source be set above 167°F (70°C)

6. Can the Heating Box™ apply direct heat source water temperature that space heating applications?
The Heating Box™ incorporates a manually adjustable thermostatic mixing valve which supplies the appropriate high or low temperature based on the type of hydronic heating used.

7. What surface area (i.e. how many square feet?) can be supplied using the Heating Box™?
The total system capacity will depend on the hydronic design and the appliance used but the maximum recommended area is approximately 2,000 square feet when the heat source is set to 180°F.

8. Are there any factors that need to be considered when selecting a heat source appliance?
The Heating Box™ is equipped with a high head pump that will achieve a certain flow rate given a certain pressure drop across the heat source's heat exchanger. Cross referencing the Heating Box™ pump curve against the appliance pressure drop curve will determine the system flow rate and BTU delivery. Select an appliance that will meet your BTU demand.

9. Are there any worries regarding domestic hot water supply temperature with the Heating Box™?
The Heating Box™ is equipped with a domestic hot water mixing valve to protect against the possibility of scalding. It ensures a steady water flow at a safe and steady water temperature.
