Using this value
Either form of this value goes in the google_product_category attribute: the numeric ID (621) or the full path ("Home & Garden > Household Appliances > Water Heaters"). Both are predefined values for the same category. The ID is the sturdier of the two, because renaming any segment above this one changes the path text and leaves the number alone.
Bear in mind that google_product_category is an optional attribute. Google assigns a category automatically, and your value is treated as a signal rather than an override. When an override actually applies.

Either row below is accepted. The first is the one to send.

This path has no comma, so an unquoted cell holds it as it stands — which is not true of every category in the taxonomy. The numeric ID, 621, is the form that does not depend on how the file is quoted.
Questions about Water Heaters
What is the Google product category ID for Water Heaters?
621. The full path, "Home & Garden > Household Appliances > Water Heaters", is the same category written the other way. The ID is shorter, and renaming a segment above this one changes the path text while leaving the number alone.
Is anything more specific than Water Heaters available?
No. Water Heaters is a leaf of Google's taxonomy at level 3, so 621 is the most precise value this branch offers. If it does not describe your product closely enough, the answer is a different branch, not a deeper one.
Where does Water Heaters sit in the taxonomy?
At level 3, under Household Appliances (604). The chain from the top is Home & Garden → Household Appliances → Water Heaters. If your product does not belong under Household Appliances, it does not belong here either — check the level above before going deeper.
What should I use if Water Heaters is not quite right?
Look across the rest of Household Appliances first — there are 11 other categories at this level: Climate Control Appliances (1626), Floor & Carpet Dryers (235920), Floor & Steam Cleaners (616), Floor Polishers & Buffers (5294), Futon Dryers (4483), Garage Door Keypads & Remotes (6741), and 5 more. If none of them fits either, the problem is higher up: go back to Household Appliances (604) and pick a different branch from there rather than settling for the closest thing on this one.
How big is Water Heaters compared with the categories next to it?
It is sixth largest of the 12 at its level, carrying 0 categories below it. A bigger category is not a better one — it just means more of the taxonomy is still open below you after you pick it.
