The PBS-250W PowerBoard Infrared Panel integrates directly into a standard 600×600mm ceiling grid,
providing comfortable, radiant infrared heat at room level. Unlike convective heating systems, infrared
heats objects and people directly — resulting in faster warmup times, reduced running costs, and zero
maintenance. Each panel operates at 230V and can be individually zone-controlled via Loxone or
standalone thermostats.

Why Infrared?
Infrared heating warms surfaces and people directly — not the air. This means faster warmup, lower heat loss through ventilation, and an even, comfortable warmth. Combined with smart thermostatic control, running costs are typically 30–40% lower than equivalent electric convective heating.

How it Works
Solar charges the battery during the day. During peak tariff hours or at night, the battery powers your home — eliminating grid import and maximising the value of every kWh you generate.
Solar → Battery (daytime)
Battery → Home (evening/night)

The Loxone system acts as the brain of the building — coordinating heating zones, lighting,
blinds, ventilation, and security into a single intelligent platform. The Miniserver processes rules
and schedules locally (no cloud dependency) with optional remote access via the Loxone app.
Heating control integrates directly with the PowerBoard panels via Tree-bus thermostats,
enabling per-room scheduling and occupancy-based control.

Why EPC / BER Rating Matters
UK rental law: Properties must achieve EPC E minimum now; C by 2030 (proposed). Non-compliance = fines up to £30,000
Ireland rental law: New tenancies must achieve BER D1 from Nov 2025; B2 for new leases from 2028 (SEAI)
Resale value: Each band improvement adds ~2–5% to market value (RICS / Savills data)
Green mortgages: A/B-rated properties qualify for 0.1–0.3% rate reductions with major lenders
Note: Figures are indicative. Exact EPC/BER requires a certified assessor (DEA/BER assessor)

How Fabric Affects System Sizing
The PBS-250W infrared panel system is sized based on floor area and building heat loss. Infrared panels heat occupants and surfaces directly — not the air — so sizing is typically 60–80% of equivalent convective requirements. Improved wall/roof insulation reduces the panel count needed and improves running costs further.
