If you have a hot water (hydronic) system, water circulates around your boiler’s combustion chamber. A circulator pumps the hot water through pipes to heat baseboards or radiators. Eventually the water returns to the unit to begin the cycle again. Steam systems work similarly except they generate steam, which rises up to radiators (no circulators are needed). A low water cut-off shuts down the boiler if water levels drop too low, preventing boiler damage.
Use your boiler to cut water heating costs
With a boiler, you can cut your water heating costs and have as much hot water as you want by installing an indirect-fired oil water heater.
An indirect water heater uses the water heated by your oil boiler to heat the water in your water heater’s storage tank. (The boiler-heated water never comes in contact with the water in the tank.) An indirect water heater heats water super-fast and it saves you money!
