We have put this page together to go over the pricing options for replacing a water heater. The following pricing only applies to houses built after the 1970’s. In older homes with a Masonry Chimney, a Flue Liner must be installed prior to installing a new Atmospheric water heater. Otherwise a Power Vent unit can be installed for roughly twice the cost of a traditional gas tank.

Bradford White RG250T6N is the most common tank installed, the basic install is $1045 for a 50 gallon 40,000 BTU water heater. There are likely to be an additional $200 in recommended in system  upgrades.

$100 Pressure Reducing Valve


A Pressure Reducing Valve should be installed if the existing PRV is more than 15 years old or the water pressure is above 80 psi. The PRV will help reduce the maintenance required for a Thermal Expansion Tank.

$60 Thermal Expansion Tank

A Thermal Expansion tank is required by all Manufacturers on all Closed Loop systems. A closed loop is created when there is a check valve in the water meter or a PRV in the system. The expansion tank should be calibrated to match the water pressure and will absorb additional volume that can accumulate from Thermal Expansion.

$40 – $70 Venting Upgrade

Many of the water heaters installed for new construction were not sized in accordance with Fuel Gas Requirements. If you have a 40,000 BTU atmospheric water heater common vented with a furnace there should usually be a 4″ vent installed.

When adding a 4″ vent and connector rise to the new unit the furnace vent may also be replaced. Usually to replace the entire venting for the furnace and water heater it would add about $70.
