Component	Parameter / Requirement	Analysis
Exterior color	RAL 8022 (dark brown)	Dark color helps absorb solar heat, assisting warming – beneficial for Canada's relatively short summer.
Inner liner	5mm steel plate + polyurea spray, color code same as 7-13	5mm steel provides sufficient strength; polyurea coating is corrosion‑resistant, impact‑resistant, and freeze‑thaw resistant – ideal for winter draining and exposure.
Insulation layer	Polyurethane foam (sides + bottom)	Full‑enclosure insulation greatly reduces heat loss. Works with the heat pump to lower heating energy consumption and prevents bottom deformation from ice formation.
Pool cover	Electric, 150W, 3×1.5mm² cable connection	Electric cover reduces evaporation and heat loss when the pool is not in use. The 150W motor has enough torque for an 8.2m length and is suitable for low‑temperature operation in Canada (if properly rated).
Composite deck	Black solid wood‑plastic composite	Non‑slip, weather‑resistant, UV‑resistant. The black surface helps melt snow. It can also hide piping and electrical enclosures, improving safety and aesthetics.

Component	Specification	Analysis
Salt chlorine generator	1 set	Produces chlorine via electrolysis of salt, eliminating the need to store or add chemicals. Ideal for Canadian homeowners performing their own maintenance. Efficiency in cold water is moderate, but works well when paired with the heat pump.
Sand filter + pump	1 set	Standard sand filtration combined with circulation pump ensures clear water. Canada's water is generally soft, so backwash cycles are longer and maintenance is simple.
Heat pump	1 set	Primary heating device with COP typically 3‑6, saving >70% energy compared to electric resistance heating. Efficiency drops when ambient temperature falls below 0°C, but fully usable in spring, summer and autumn.
Countercurrent swim unit	1 set	Produces an adjustable current, allowing the user to swim in place. This compensates for the 8.2m length, delivering an "endless pool" experience.
Fountain equipment	1 set	Adds visual water feature; helps dissipate heat and increase oxygen in summer. Must be drained in winter to prevent freezing.
Pool lights	4 units	Evenly distributed along the 8.2m pool. Provide illumination for night swimming and safety.

Component	Requirement	Analysis
Wires	US standard (AWG, UL/CSA certified)	Must use AWG‑rated, CSA‑certified wires with insulation suitable for Canadian Electrical Code (CE Code) low‑temperature requirements.
Distribution panel	US standard + special requirement: 220V 60Hz and 110V 60Hz	Canadian residential supply is 120/240V 60Hz. Thus, both 110V (nominally 120V) and 220V (nominally 240V) circuits are required: - 110V circuit: pool lights, electric cover motor (150W), salt chlorinator controller, pump control signals, etc. - 220V circuit: heat pump (high power), countercurrent swim unit (may require 240V), sand filter pump (if 240V version) Two separate sub‑panels or one split panel ensure different voltage devices do not interfere and comply with CSA C22.1 grounding and GFCI requirements.
Electric cover cable	3×1.5mm² cable connection	1.5mm² is approx. 16 AWG, capable of 10‑13A. The 150W motor draws only about 1.25A (at 110V) or 0.7A (at 220V) – sufficient margin. Must use waterproof connectors and cold‑rated flexible cables.
Other components	Countercurrent unit, heat pump, etc. – require CSA certification	For export to Canada, all electrical components must bear CSA or cUL certification. The table specifies "US standard", implying compliance with such recognized certifications.
