Do you design or
install hydronicsystems using
water-to-waterheat pumps?

The distribution
system will dictate
the required
temperature to meet

Key Question
Why are we sending the hotte(or Coldest) water in the systeback to the buffer tank where
is mixed and diluted to a lowetemperature before we send i
to the load?

Bottom LineIt is often said that geothermal costs too muc
Frankly, I think we are failing to maximi
the value. Through simple design
techniques and a fundamental
competence in the design community w
can sell the technology at a competitiv
price and actually deliver outstanding
value!
