Oil Boiler Replacement with Condensing Gas Fired Boiler

Replacing an oil boiler with a gas boiler is not always the best option, but in this scenario, it made the best choice.

• The oil boiler worked fine and  was actually in very good shape. 
• The chimney needed to be relined
• The oil tank needed to be replaced
• Gas was already installed at the house with an adequate gas line and meter size
• Oil fired boiler used a direct coil for domestic hot water. 
• Oil fired boiler was much larger than needed for heat loss (Manual J)     
• The cost to replace the chimney and the tank was more than the cost of a new boiler.  The best efficiency on oil boilers is in the 86% range. Tax rebates require 90% efficient equipment for $1500 tax credit.  Instead, the choice...

• Installed a new 95% efficient gas boiler with load rating to match Manual J, the old boiler found a new home (recycled).
• Existing stack used to route new plastic PVC pipe stack and sealed at top to stop further water damage. 
• Oil tank removed and used
• Indirect fired domestic hot water heater with thermostatic mixing valve
• Clean operation of gas with less maintenance issues than oil fired equipment.
