* Do not attempt to fill a large bathtub at full faucet flow. Tub faucets are designed to dump hot
water from a storage tank heater to maximize the useful quantity available. Your Eccotemp will take
longer to fill a tub, especially in the cooler months of the year but you will have continuous hot water
for as long as you wish to bathe for as many baths as you desire.
** Check listings in your area for local Heating & Plumbing or Appliance Repair companies for labor
estimates. Check for Warranty coverage on labor charges. For further assistance, call Eccotemp at
