No one there '****es and moans' about DIY's. We just don't like DIY's that
call us back after the mail order radiant systems don't work right either
from the error of the company that sold it to them or installation error.
Usually, the cost of fixing most errors ends up being more than the
installation would have cost if a trained, licensed contractor had done the
install to start with.

A real professional would welcome this situation. It's an opportunity
to help someone and make some money.
