Will water heater freeze in garage?
The garage is unconditioned, but insulated (R-15 whole wall, no slab edge or sub-slab insulation), and obviously has some exposed plumbing in it. Right now, the temperature in the garage doesn’t get low enough to present a freeze risk, probably aided by the water heater’s standing pilot light and hot metal flue.
Do water heaters need to be enclosed?
Water heaters must be surrounded by a certain amount of clearance, or air space, to function properly and safely. A clearance area of 12 inches is required on all sides of a hot water heater. A certain amount of airflow is also required for proper combustion and ventilation.
How do I keep my hot water heater from freezing?
One of the best things you can do to prevent your water heater from freezing is by installing freeze protection solenoid valves. The valves will automatically open and release the water from the unit in case there is a power outage. Another thing you can do is place a cover over the intake and exhaust vents.
Do modern hot water tanks need insulation?
Modern hot water cylinders often have insulation already in the form of hardened foam, and this is usually enough to keep them well insulated. But older tanks may need extra insulation.

Should hot water tanks be insulated?
Benefits. Insulating your water tank, pipes and radiators is a quick and easy way to save money on your bills. Lagging water tanks and pipes and insulating behind radiators reduces the amount of heat lost, so you spend less money heating water up, and hot water stays hotter for longer.

Does a water heater need ventilation?
All natural gas water heaters must be vented to the outdoors to remove the byproducts of combustion. Atmospherically venting gas water heaters is the most common type of venting option used.
Will a hot water heater freeze?
Any water heater can freeze if water is left inside it
Tank water heaters usually hold between 40 and 55 gallons and can require electricity. So when the power goes out in freezing temperatures, the water eventually can freeze, expand and burst the storage tank.
How long does it take for a hot water tank to freeze?
So if you use insulation similar to a home water heater, you’ll end up with a heat leak about big enough to cool 500 gal 0.1°C/hr. Freezing water requires removing latent heat equivalent to about 80°C cooling. So maybe freezing the whole tank will take roughly a month.
Do I need a water heater insulation blanket?
If your heater is located inside the house and in the rooms, your home heating is keeping it warm enough and you do not need any extra insulation. But if it is located in the attic or the garage, an insulated blanket will help retain heat and avoid energy wastage.
