Fluid heating in floor using pex and the former heating system.
As with most buses mine has that water valve that is by drivers foot that sent water to the back heater. My 98 Ford B700 Thomas body has a very large pump up on the firewall to circulate the water.
Has anyone explored the idea of using the engine heat to heat the floor while the engine is running? Add a valve to switch from the engine to another heat source.
