Thank you for your question.
I really need to look into boat installations more, we are getting quite a few questions about it at the moment.
As with a house installation, you need a stove that is the correct size for the space - try our our stove calculator to see stoves with suitable power - https://www.directstoves.com/stove-calculator
I would strongly recommend you contact an installer with previous boat experience and take a look at the Boat Safety Scheme website - https://www.boatsafetyscheme.org/stay-safe/solid-fuel-stoves
If your installer can provide you with a shopping list, we can usually supply all the items needed at a competitive price.
Hope this helps?
