Solar Benefits on a Heat King

Heaters sit all summer and likely were not fully charged at the end of last season. Adding ThermoLite® 40w solar panels to your Heat King offers:

Increased battery life: Keeping batteries charged all year round will negate failure from extended periods of low charge levels and proliferation of sulfation
Fuel savings: Reduces load on the engine with alternator working less and reduced cycle-sentry operation
Extended component life: Run time is reduced, alternator offloading and reduced starter engagement
Improved employee efficiency: Cuts time spent managing low battery alarms and battery breakdowns
