What We Offer for Tankless Water Heaters in Plainfield
- Victorian and early-1900s homes here often still have original cast iron waste stacks and supply piping that has been patched at each renovation instead of replaced.
- Many of the big houses were converted from coal to oil and later to gas, leaving an oversized boiler and improvised near-boiler piping behind.
- High ceilings and balloon-framed walls make retrofitting ductwork invasive, so zoned or ductless cooling is usually the practical answer.
