<div class="moz-cite-prefix"> I hate crawl spaces. And so will
you after doing much work in one, even if you don't have to wend
through many spider webs. A high water table portends crawl space
moisture issues too.<br>
Insulated slab on grade has worked very well for me. Put
moisture barrier underneath (Visqueen or equivalent works).<br>
If it's occupied all year, insulation on the perimeter down to
the footing is best. The thermal time constant will be very long,
but you'll lose few BTU over the long haul. An insulated break
(1" foam) between the stemwall and slab as well as insulation
outside the stemwall works well.<br>
If it's not occupied year-round, you'll want a shorter thermal
time constant, so would then want to insulate under the slab -
again with foam. Keep the stemwall/footing insulation at the
perimeter. Most of you heat loss will be out the sides near the
surface, whether you have under-slab insulation or not.<br>
<br>
I put very minimal pipes in the slab (ground floor drain only),
and bring all else inside and construct chases for most plumbing
& electrical. Protects from freezing better and MUCH easier
access for any maintenance (& even initial installation).<br>

I am on the third house and hope I can impose with a few
questions to those who've much more experience than I.
I've only built from scratch, so have no feel for the
following.<br>
<ol>
<li>Which is best: insulated slab on grade or an
insulated crawl space? The conservation folks (and I
agree) will not allow a basement, due to the water
table. <br>
