FAQs
Rinnai PB Series Split: your questions
What sizes does the Rinnai PB Series Split come in?
6 capacities: 2.6kW (HSNRP26B), 3.5kW (HSNRP35B), 5kW (HSNRP50B), 6kW (HSNRP60B), 7kW (HSNRP70B), 8kW (HSNRP80B). Each size has its own page with sizing guidance.
Which Rinnai PB Series Split size do I need?
As a rough guide, allow about 0.12 to 0.14kW of cooling per square metre for an insulated room, going by Mitsubishi Heavy Industries' sizing chart. A 20m² bedroom needs about 2.4 to 2.8kW, so a 2.5kW covers it if the room faces north, and a 55m² open-plan area needs about 6.6 to 7.7kW. Insulation, ceiling height and afternoon sun all shift the number, so use our capacity calculator or send us photos and measurements for a precise recommendation.
What warranty applies to the Rinnai PB Series Split?
Rinnai backs it with 5 yr parts & labour, and our installation carries our own workmanship warranty on top.
