Looking for that toasty feeling - 2

Having switched the lounge area around there is definitely a better distribution of heat. Sadly there is still no heat towards the back of the boat or even the desk area behind the lounge. To rectify this problem we can either fit a back boiler system or try and move warm air to where we want it.

A backboiler consists of a stove with a space to heat water behind it. As the water is heated from the fire the hot water rises and enters a pipe system that runs the length of the boat in a loop with or without radiators. The system returns to the fire with the water having been cooled on its travels. This rotation of water is purely based on hot water rising. To buy a backboiler is quite an outlay and they can be dangerous if the water stops circulating so an alternative will be tried first.

To push warm air around there are fans available that can push the heat towards where you want it but I can't see this working effectively due to the length of the boat. I am planning a system that draws the heat away from the stove with low voltage fans. I'll fit the fans so heat is drawn into the desk area then into the bathroom and finally into the bedroom. There's an option to fit more early on so that the warm air pushed into a room isn't immediately drawn out again.

If the air system doesn't work then the backboiler will need to be considered.
