might be a Glowing Embers

A lot of young JM's will have reddish stems, especially on newer growth. Not a lot to go on but the straight species, Acer palmatum, will often produce growth in young trees that looks very similar to your photo. And because they are not named cultivars, they are often sold at significantly lower prices than named forms.

As an aside, your tree looks to be planted rather close to the house -- too close I'd guess. Even quite dwarf forms of JM's will produce a relatively wide canopy in time. Unless it is a very vase-shaped selection, you should allow about 10' away from any structure for proper clearance and air circulation.
