Being a skinny bald headed person I am the sort that wears a light fleece whilst others wear T-shirts in summer sitting outside a pub in the UK come 8pm or in other words I feel the chill like no other.
There was no working heating system on the boat which has big windows when I brought it so fitting heating was top of the list. I spoke with the head man in the yard and picked his brains and experiences with Webasto, Eberspacher and Planar heaters regarding costs of buying and servicing and was undecided. Then he threw me a curve ball of a cheap Chinese heater instead.
Costing around £100 plus the costs of a proper exhaust I figured if it only lasted a year or two It wouldnt owe me anything so I took the gamble and won. So far it has lasted around 3000 - 35000hrs often running 6hrs a day in winter without fault. The display controls the output with an on/off programmer plus I have an on/off key fob for turning it on without getting out of bed.
The fuel pump is mounted below the take off from the tank so it is flooded all the time and the piston pump pushes fuel to the heater (they dont suck fuel in to the pump) You should use the supplied nylon fuel hoses on the pump outlet as some rubber hoses can expand a little under pressure and adding extra rubber mounts or suspending the fuel pump makes it quieter.
