Hi Mac, We have used tiny RV-type propane hot water heaters (ie 1-2 gallon) situated at base of generator, plumbed into the coolant system with a thermostat control and it thermosiphons. One site has a 30 kW Kohler genset with 6 cyl GM industrial engine and this has been in place for 5-6 years and works reliably. Kevin
