Five-question shopping guide

Turn your room needs into a real model shortlist

Answer five questions. We’ll screen the catalog by published capacity, climate, zone, installation, and certification fields—then show exactly why each model appears.

This is a planning shortcut, not a Manual J load calculation or installation approval.

Question 1 of 5
What space are you planning for?

These ranges are a starting point. Ceiling height, insulation, windows, sun, and local weather can change the load.

How cold are your winters?

Cold-winter matches require a true cold-climate listing.

One room or multiple rooms?

Multi-zone matches require a zone marker or multi-zone label in the published model identity.

What is your installation plan?

A “DIY” series name is only a clue. The exact manual, electrical work, permits, and local rules still control.

What must every match include?

Choose one hard requirement. The shortlist will not guess when a field is missing.

Want a more detailed size estimate?

Add ceiling height, insulation, sun exposure, climate zone, and room type in the full calculator.
