How It Works – Arctic Heat Pump
Integrated Heating Solution
Built in Back up
User Friendly Controller
So how does it work?
A brief example will show you how our heat pump for cold climates works. Our factory controller system can manage two zones, and unlimited zones with addition of the MX controller.
- Space Heat
- Space Heating and Cooling
If we have set up Heating and Cooling, then the heat pump will control both the circulation pump and a 3 way zone valve. Using the tank temperature sensors and an air temperature sensor built into the controller, the pump will turn on and default to the priority zone (either buffer tank for heating or the air temperature sensor for cooling) until it reaches the set temperature. As an example if cooling is priority then the system will cool the room to the set point temperature then the 3-way valve will divert to the buffer heating zone tank and the heat pump will switch to heating to fill its energy needs of the buffer tank which provides heat to zones like domestic hot water, space heating and pool/hot tubs. If the cooling zone requires cooling again the 3 way valve will switch to the cooling zones and the heat pump will reverse its self and provide cooling.
Basic Diagram for Heating and Cooling
Domestic Hot Water & Heating Cooling
Domestic Hot Water & Heating Cooling – by adding a second zone valve the Arctic Heat Pump is able to heat both domestic hot water and a buffer tank. In the summer this mode can be set to heat domestic hot water and cool the buffer tank to provide zone cooling. Note Hydronic heating cannot be used for cooling so you would require fan coils for summer cooling, a seasonal valve would isolate the radiant floor heat as we don’t use in floor heat for cooling.
Fan Coil Heating/Cooling
Fan Coil Heating/Cooling is easily done through the use of the buffer tank. The heating/cooling zone is controlled separately by individual room thermostats found on the fan coils. A centralized controller connects to the zone pump. When any of the room zones call for heat or cooling they will close their contact and activate the pump. Each fan coil has an internal 3-way valve so that only the fan coils that have a heat or cool demand will allow the flow.
Changing the heat pump for heat to cool will determine whether the buffer tank stores hot water or cold water.
Advanced Heating/Cooling Design
Advanced Heating/Cooling Design- by using a PAW Modular Hydronic Heating Solution and Resol MX Controller we can help you design larger residential systems or commercial systems. Multiple heating sources can be combined such as heat pump with solar to give even greater efficiencies. Call us to discuss customization of your project. Design is always FREE
Pool or Hot Tub & Heating/Cooling
Pool or Hot Tub & Heating/Cooling – by adding a second zone valve the Arctic Heat Pump is able to heat both a pool or spa and a buffer tank. In the summer this mode can be set to heat pool/tub and cool the buffer tank to provide zone cooling. Note Hydronic heating cannot be used for cooling so you would require fan coils for summer cooling, a seasonal valve would isolate the radiant floor heat as we don’t use in floor heat for cooling.
