Philadelphia Gas Works on Tuesday announced it has launched a website to promote its EnergySense conservation program and has temporarily doubled the amount of rebates it is offering customers for heater upgrades — up to $2,000 for a high-efficiency boilers.

The city-owned utility, which is spending $54 million over five years on energy-efficiency programs, says that only 160 residential customers have received rebates since the program started last year. Homeowners, small businesses and landlords with individually metered units can now get up to $2,000 in rebates for a high efficiency natural gas boiler and up to $500 for a high efficiency furnace. "That's a limited time rebate," said Barry O'Sullivan, PGW's spokesman. He said the offer will end at PGW's discretion.
