Radiant Heating

I have several questions concerning my radiant heating plans:
I looked through a bunch of threads on this topic and didnít find any info about using solar heating (I am talking about solar water heaters, not using solar panels energy to heat water). Has anyone done that and if so can you share your feedback? I am planning to use solar plus Espar diesel boiler.
Most people use multi-zone systems. Mine is going to be pretty small (about 100 ft of PEX pipe). Can I do it as a one zone? To complicate things a little, I have to mention that I have Gillig LF so the back part (9 ft long) is 16 inch higher than the rest of the bus.

We have a low floor with steps in the back and floor heat.
Depending where you are and your insulation floor heat can work well to 30-40 F. . lower then that and you need radiators with fans to help out.
During daytime sun shining thru the windows will do the same as solar collectors.
It would be better just to run PV and use a heat pump as used in water heaters. In the summer you can have the PV generate electricity for cooling.

Good luck

PV? sorry.

I am intrested in this topic also.

I am considering running a copper coil in and/or around the woodstove chimney to circulate the heated water to the factory heater units to help distribute the woodstoves heat.

Radiant heat sounds awesome but the work and investment seems to me, prohibitive.

I have 2 inches of insulation with in floor as well as radiators with fans. From a below 0 cold start, using radiators and floor, I can get the bus to 65į in less than an hour. Once warmed up I can turn off the blowers and just the floor will maintain down to 10į or so then I need to run some of the blowers.

Even at below 0į my boiler cycles so I know I haven't reached it's limit.
