Anyone experienced with HPWH??
Costing from $700-$1,500, these systems may be a great way to reduce humidity while generating inexpensive hot water. If they are tied to the AC return it could reduce the AC load requirements. Manufacturers claim HPWH have the highest ROI compared to other alternatives. A whole house dehumidifier costs 500-$2,000. A solar hot water heater costs upwards of $3,000. Hot water generation represents 20-30% of a family's energy bill.
I seen negative posts on these systems but few responses with actual experience working with them.
