i took a chance on this heater as one i had fitted in my van was £800.00
this was for my race trailer and i fitted it myself, it actually is better than the one in my van having digital control and a remote so when i am laid in bed i can control it, even on the lower setting it kicks a lot of heat out, absolute top quality and value for money is an understatement, not sure about parts but at that price its worth having another for spares if you need something
