Resi Systems With Reheat?

DuMass

Are there any new larger resi systems that utilize reheat coils for humidity control, such as by using condenser waste heat?
I was just thinking about how the new high SEER coils have such large surface area, that it seems extended air-over run times are needed to reduce humidity without overcooling the space.

I know this is common in large commercial cooling applications with varying occupancies, but seeing as how many homes these days have become McMansions, I was wondering if this is also being used there as well.

Thanks

I can't think of the name of the company. But their is one that builds passive reheat coils into their air handler.

That’s good to know. I assumed most manufacturers were likely focusing on ERV and dehumidification wheels or whole house dehumidifiers.
Seems that condenser waste heat is an abundant unused source of energy, but I suppose the real problem is how to get it to where it’s needed, at least with the smaller air cooled systems anyway.

The problem is upfront cost. Most home owners would object to the extra cost. so there isn't a big demand for reheat in the residential market.
