My furnace was just replaced with a high efficiency one. The contract includes a chimeny liner work for water heater required by city code. However, the contractor told me that the chimeny of my house is offset inside and the 4" liner cannot be put through. To meet the city code, the contractor gives me three options, 1. repare chimeny (cost unknown), 2. add power venting on the water heater and vent through the side wall xxxx, 3. replace the water heater with a power vent one and vent through the side wall xxxx. I am wondering if some one here can tell me other cost efficient options. Thanks a lot.
No pricing please and thank you.
