I'm looking to buy a small heater for my Legend 33 that I can leave on over the winter. I've been looking round but can't find anything that helps me calculate the minimum power requirements. I'm not looking for anything too big because if I decide to stay on board overnight I have a large halogen heater but I don't want to leave that on unattended.

I've got my on one of those tube heaters but not sure if 80W is enough. The boat is in Weymouth so its not expected to get too cold for a long period.

As always thanks in advance,

Simon

80 w tube heaters are normally 2 ft long. Have a look at the one on Amazon to compare.
 
I bought an 80W tube heater for my motorhome. When the outside temperature is below zero the heat output of the tube is so small that it makes no discernable difference to the temperature inside the van. When we lived in Holland we had two 500 watt convection heaters on the boat (Sadler 34). Turned down low on their thermostats they were very effective at taking the chill off the internal temperature.
