Mike Dawson – An explosion blew out part of a home yesterday morning after a lingering cloud of propane was ignited by a hot-water heater, according to police.

Before dawn, David Porvaznik was in his bathroom at 82 Warwick Turnpike running the hot water when he was rocked by an explosion, police said.

The blast blew out some of the basement and broke windows, sending debris into his yard.

Porvaznik, 58, who was alone in the house, wasn’t hurt, police said.
