1) Is there a way to add a circulator to a gravity-fed hot water heating system - one zone only gets heat when the boiler has been running for a long time e.g. morning when thermostat goes from 62 to 70F?
2) What annual maintenance should be done on hot water heating system? Empty the system in the summer?
3) Some corrosion is appearing on valves (not all) - any way to prevent?
