Oil Furnace Boiler Pump - A major component of oil furnaces is the oil pump and its job is to pump oil from the oil tank to the oil burner. It is important that the oil system is primed and free of any objects or particles that can plug the system. As well the oil pumping system must have integrity with no holes in the oil pipe where the pump can suck air into the oil line. Any air sucked into the line or a plugged oil line will cause problems with the oil burner that may result in a non-functional burner or a burner that does not produce efficient heat. (more…)
HVAC Tip - You can add energy savings by placing a blanket wrap insulation around your water heaters. Additionally, for electric water heaters, you can have a timer added to the power circuit to turn the water heater off in times when there is no usage. For example: Set the timer to turn the water heater off from 10 p.m. to 4 a.m. Most timers can be customized and set for different times so that the water heater is turned off for most of the day and night. This, along with the insulation (which will keep the water hotter longer), can save in energy usage and your energy costs.
