Heater Pump Heater or Hybrid Water Heater

FAQs About Water Heater Users
Can A Water Heater Be Installed Outside?
Yes, as we discussed above, you can get your water heater installed outside (see also ‘Can Water Heaters Be Installed Outside?‘) in certain instances. Note that gas and electric water heaters are specifically not designed for outdoor installation, thus installing such water heaters indoors.
However, if you get a shelter constructed outside, you may consider installing such heaters outdoors.
On the other hand, gas tankless water heaters are specifically designed for exterior use and installed outside. Also, electric tankless heaters can be installed outdoors. However, some sheltering is required to protect the heater unit from harsh weather conditions.
To further elaborate on this, should water heaters be installed outdoor depends on 2 major factors: water heater type and climate.
Do Outdoor Tankless Water Heaters Freeze?
While a tankless water heater comes with certain restrictions, it functions well in winters. Tankless water heaters are 100% effective during winters as they use condensers to preheat the water.
Hence, it does not take pretty long for water to reach the warm water flow’s predetermined temperature. Usually, at a rate of nearly 1.6 gallons every minute, water reaches the set temperature.
Note that initially, it might flow with reduced pressure as an outdoor water heater takes time to heat the water. But ensure the water would surely be as warm as desired by you.
In contrast to a specific belief, the outdoor water heater’s warm water temperature is not restricted by the outside temperature.
Most even have this question: are water heaters highly effective in wintertime, despite the water temperature before entering the warm heater’s heating system?
The answer is Yes. However, the outdoor water heater can freeze if few specific precautions are avoided when the temperature falls below a particular level.
How Do I Keep My Outdoor Water Heater from Freezing?
Most outdoor and indoor water heaters consist of inbuilt freeze protection against the temporary cold winter temperatures that range anywhere between -5-degree Fahrenheit and -22-degree Fahrenheit.
Note that the protection fails to withstand if the temperature goes below the set freezing protection temperature. Please follow these specific steps to prevent the water from freezing in the outdoor water heater.
- To start the process, winterize your water heater.
- Firstly, turn off the unit and unplug the power source.
- Next, turn off the water supply & drain out all water from the heater.
- Lower the water pressure, then disconnect water pipes from the water heater.
- Ensure to cover the vent termination for the exhaust and intake to keep the debris out.
After this, install a dual or concentric vent system facing the vent pipe away from the wind not to freeze. Install drain pipes in locations not subject to freezing, like inside the wall.
Allow sufficient combustion air for the gas-powered electric appliance to prevent the negative draft from water freezing in a tankless system. You can also utilize a backdraft reduction as this closes the backdraft flapper.
Lastly, you can continuously run a little stream of warm water to prevent it from freezing. Following the steps mentioned above can keep your outdoor water heater working effectively throughout winter, irrespective of the freezing temperature prevalent outside.
You might not require doing much if the temperature falls just for a little while. If you expect the weather to remain cold for a long time, winterize your outdoor water heater. In case you are unable to do so, ensure to call a professional for the same.
