Hi, just our view, we always recommended live aboard boats to have diesel fired central heating (webasto, mikuni, eberspacher {actually in reverse order of preference} even hurricane) in conjunction with a solid fuel stove leaving the usage of either system to their own preferences knowing they would be covered for most circumstances.
One brilliant piece of kit we have come across, especially beneficial to the OP if he is living aboard a few days a week, install your preferred diesel heating system but switch it on from a simple no cost call from either a mobile or landline for a pre determined time and come home to a pre heated boat.
We have used the system all last winter using the boat every weekend, 2 hours before arrival phone the boat, eberspacher on, arrive toasty.
Change your plans, text the unit and turn it off. Many options are possible.
Regards
Roger
