Does anyone know if the waterflow through a heater matrix on a 1984
110 is constant or switched to flow only when the control is set to hot (warm) ?I'm thinking of re-routing the pipes to go around the fuel filter so thinning this biodiesel I'm starting to use (it does help and they sell their own gubbins to warm it, but I'm a yorkshireman so looking for a cheaper way).
