Inadequate Heat

By
Home Inspector with King of the House Home Inspection, Inc. Home Inspector Lic #207

I have done a number of inspections at houses where there was inadequate heat. A house should have heat in every livable room. That does not include hallways, closets or bathrooms, although most of us like heated bathrooms in the dead of winter. At many old houses I might find a single space heater, or maybe a baseboard heater in one bedroom but no heat in other rooms.

What buyers often do not realize, in taking on such a house, is that the problem caused by lack of heat might go beyond simply being uncomfortable in cold weather. Lack of heat, or poor distribution of heat, can lead to condensation forming on walls and microbial growths (read that as mold) finding a great place to grow in those damp and unheated areas. Mold is the result of excess moisture and/or inadequate ventilation.

That's a new one on me - microbial growth read as "microbial growth!"

Here if a closet is larger than 6x6' it is required to have HVAC.

Jay,

Microbial growth is the recommended terminology per our WSDA. Microbial growth the result of insufficient heat or lack of ventilation. As they say, we really do not know the biology of the organism, a mold, a yeast, even decay spores in some instances are white, so microbial growth is the preferred term.  I use it sometimes, on some occassions I say mold or just call it a fungus.

Here they go by the IRC and it for sure excludes all closets as requiring heat.

Kristin and Lenn,

Remember that codes are bare minimums....the worst house you can legally build. Therefore, when anyone starts tossing out "built to code" that really does not impress too much. This is what code says:

There must be an installed heat source capable of producing at least 68 degrees at 3 ft over the floor in any habitable room.  Portable heaters will not meet that requirement. Habitable is, by code, defined as: A room used for living, eating, sleeping or cooking. EXCLIDED-- Bathrooms, closets, halls, storage spaces, laundry areas.

As you say " bare minimums" and sometimes when it's barely enough you get morethan you bargained for.

Mold breeds in and grows in not so perfect conditions and does not know about codes lol

Enjoy the day

I think Don may be onto something. We need to slap mold into line and have it follow code.

I have seen more than a few homes where the walls in the entire home look something like your picture form being winterized (no heat).

I agree with the term microbial growth.  I was kidding you about it's being a generic word.  Here large closets, defined above, and any closet on an exterior wall requires HVAC.
