Armed intruders allegedly stormed a home in regional Victoria and assaulted a man, before throwing him into his car boot and burning his house to the ground.

Three unknown people broke into a home on Melba Highway in Yea, about 110km north-east of Melbourne, just before 2am today, according to Victoria Police.

The trio were allegedly armed with two firearms and a machete.

Police believe they demanded cash and firearms from a 58-year-old man at the home, then assaulted him before dragging him out of the house and into the boot of his own vehicle.

He allegedly got out of the vehicle and was threatened again by one of the offenders, whilst the other two set the house on fire.

The offenders allegedly poured petrol on the man, then fled the scene in a vehicle.

Three firearms were stolen from the property during the incident.

Firefighters arrived to find the home engulfed by flames.

It took them about two hours to bring the blaze under control.

"The house was destroyed by fire," the Country Fire Authority said. 

The man was treated by paramedics for non-life-threatening injuries.

Police are investigating the matter and urge anyone with information to come forward.

No arrests have been made.
