What Is The Purpose Of  VAC On A Water Heater

So what is VAC on water heater? Why do we need VAC or vacation mode in a water heater? What is its purpose? Is it necessary? Won’t you save more if you just turn the heater off? We will be answering those questions in a while, but first, let’s talk about its purpose. When a water heater is set to vacation mode, this is made for homeowners who will not use their water heater for a while. Probably because they will be away on a trip, and that sort of stuff makes the water heater work with lower temperatures to save electricity.

If we don’t have this option, your water heater would heat the water and maintain that high temperature with no one even using the hot water. What a waste, right? Well, if you’re thinking, “why not just turn it off if you’re not going to use it?” there is one problem. In cold places where the temperature is so low it reaches the freezing point of water, you’ll have a hard time doing something about the frozen water left in the pipes when you come back from your winter holiday vacation or trip.

To avoid this, when set to vacation mode, the water heater will still keep the system warm while using the least possible energy. This solves both the freezing problem and the energy problem. But what if it’s not that cold where you’re living? Then, in this case, it is beautiful just to turn off the water heater so that it won’t use any energy or electricity at all. They added this setting because most people who purchase and use water heaters live in parts of the world where they experience cold winter seasons or climates.

Turning On Vacation Mode 

Depending on the water heater you have, it might or might not have the “VAC” setting. Newer models of water heaters will have this setting.

It would be better if you had an owner’s manual for your water heater system; if you don’t, you can always contact the place where you got it from. You can also just look for it yourself since there would probably be a label or something.

Depending on how high-tech your water heater is or what type it is, your thermostat could be as simple as a dial with labels or futuristic as an electric water heater with touchscreen thermostat settings. Once you turn the setting on, you are ready to leave the water heater during your short or extended leave. It’ll then be prepared to heat your water as soon as you come back.
