The Klimaire KMIP-KIWP DIY Series 2-Zone 18k pairs two heads with one 208/230V outdoor unit at a certified nominal SEER2 24, EER2 13, HSPF2 10.5 on current R-454B refrigerant. From the DIY-oriented line, its rated heating holds the full 20,000 BTU from 47F down to 17F before easing to 16,000 BTU at 5F.

The SEER2 of 24 is high for a value brand, and though the line is DIY-oriented, professional installation is still recommended. It is not ENERGY STAR certified and sits below the top premium brands on brand and dealer support.

Dealer-quoted.

Compatible indoor units

This is an outdoor unit. You choose its indoor heads separately - up to the maximum this condenser supports - and you can mix room sizes and styles across the zones. The models below are the heads this unit is documented to pair with.

  • Wall-mounted air handlers

    9k, 12k

    Model numbers
    • 9k: KIWP09H2-41T
    • 12k: KIWP12H2-41T

Sizing note: do not just add up the rooms. Multi-zone condensers have a maximum total connected capacity, and connecting more head capacity than the unit is rated for is a common installer mistake that hurts efficiency and comfort. Match total head capacity to the condenser's rating.

Frequently asked questions

Can I install the Klimaire KMIP-KIWP DIY Series 2-Zone 18,000 BTU R-454B 208/230V (KMIP218-H225-4) myself, or do I need a pro?
Klimaire KMIP-KIWP DIY Series 2-Zone 18,000 BTU R-454B 208/230V (KMIP218-H225-4) is sold as a DIY-installable system. The electrical circuit is the part that is not DIY: plan on a licensed electrician for the dedicated circuit, and check whether your local permit office requires a permit for the install.
Will the Klimaire KMIP-KIWP DIY Series 2-Zone 18,000 BTU R-454B 208/230V (KMIP218-H225-4) keep heating in a cold winter?
The AHRI/ENERGY STAR certification lists 16,000 BTU/h of heating capacity at 5F. Rated heating operation extends down to -13 F. Certified heating efficiency is 10.5 HSPF2. Match those numbers against your climate's design temperature - in cold regions, output at 5F matters far more than the nameplate capacity measured at 47F.
What electrical circuit does the Klimaire KMIP-KIWP DIY Series 2-Zone 18,000 BTU R-454B 208/230V (KMIP218-H225-4) need?
Published electrical requirements: 230 V voltage, 16 A minimum circuit ampacity, and 25 A maximum breaker or fuse sizing. Confirm the final circuit against the unit nameplate and local code with a licensed electrician.
How far can the outdoor unit be from the indoor head?
The published maximum line-set length from the outdoor unit to one indoor head is 82 ft. The combined piping limit across all heads is 131 ft. The outdoor unit's factory charge covers up to 49 ft of line; longer runs need added refrigerant. Measure the planned routing before ordering.
What warranty does the Klimaire KMIP-KIWP DIY Series 2-Zone 18,000 BTU R-454B 208/230V (KMIP218-H225-4) carry?
The manufacturer publishes these warranty tiers: Registered: 5 yr parts / 7 yr compressor (registration/installation terms). Score uses Registered.. Registration requirements and proof of qualified installation commonly affect coverage, so read the warranty terms before install day.
