After a burn in my menage, I wanted to portion my make’second as well as don’ts for storing things almost a water heater. That is, I wish individual had told me that a H2O heater has the potential to be a burn down together with rubber run a risk together with that there are rules governing where it tin live located together with what tin live placed past it.
In this article, I have yous through the rules about storing items well-nigh H2O heaters that can live read inward the International Residential Code (IRC), which is applicable inward all 50 states of America, too equally other locations.

As per the IRC, allowable clearances are dictated by the manufacturer. Do non install water heaters nigh to ignitable construction too do not store ignitable material nigh H2O heaters. Fuel-fired water heaters cannot be installed inward storage closets. Nothing must block the airflow.
Clearance Depends on Manufacturer Instructions
According to IRC Section G2408.v, whatsoever oestrus-producing appliances, such as H2O heaters, ask to be installed alongside the required clearances between the appliance and any ignitable materials and construction. These clearances will be specified inwards the manufacturer’sec instructions.
The required clearances can live minimized according to the IRC Section G2409 (I talk more than nigh this inwards the side by side section), simply it is important to ever accept slow access to the H2O heater.
This is because by easily viewing the water heater, yous can find whatsoever required maintenance such every bit a leak or corrosion. If there was a pocket-size clearance from another object to the water heater, you lot may miss these maintenance tasks until the harm was more than severe.
The IRC ofttimes gives terminal clearance authority to manufacturers, such equally is the instance here. Clearances to objects such every bit a door swing, drawer force, overhead projections, too/or shelving necessitate to adhere to the clearances provided inward the manufacturer’s instructions.
The aforementioned IRC section farther states:
“Devices, such equally door stops or limits together with closers, shall not live used to render the required clearances”.
This means that if something would swing into the H2O heater’sec clearance expanse, ane.e., the expanse that must live costless of all obstructions too objects at all times, and so using a safe doorstop or the like to end it from swinging into this space is non a viable solution.
How to Legally in addition to Safely Reduce Clearance
According to section G2409 of IRC, the reduction of required clearances to combustible materials, such every bit a water heater together with other combustible material, can be safely done past protecting the combustible items equally described inward the Table G2409.two of the IRC.
For example, you lot tin can trim back the required clearance past installing the following betwixt the water heater as well as the combustible fabric:
- iii ½” thick masonry wall amongst or without ventilated airspace.
- ½” insulation boards over ane″ drinking glass fiber or mineral wool batts.
- 0.024″ sail metallic over ane″ drinking glass fiber.
This functions as an extra layer of protection, provided that it is permitted according to the manufacturer’second instructions. However, the clearance to water heater appliances should never interfere amongst combustion air, draft hood clearance, and accessibility for service.
Fuel-Fired Water Heaters Can’t Be inwards Storage Closets
Certain types of water heaters, such equally a fuel-fired water heater, cannot live located inwards storage closets. This data is establish inwards department M2005.ii of IRC. But why is this prohibited?
Firstly, and about plain, a fuel-fired water heater is a fire gamble, then to locate it inward a unopen in addition to cramped unit of measurement alongside a bunch of combustible materials is but asking for problem.
Secondly, if the water heater was inward a storage closet it would likely live less visible as well as or less accessible. Visibility together with accessibility are of great importance for appliances similar water heaters. You have to live able to see if anything is amiss, together with y'all need to be able to get to the heater chop-chop if there is something incorrect.
Can You Install a Shelf Above a Water Heater?
You tin install a shelf above a H2O heater, but exclusively equally long as at that place is plenty infinite for the maintenance folks to service the H2O heater too the shelf does non set a burn run a risk.
By looking at the manufacturing instructions dictating the clearance distance from combustibles, you can determine if at that place is plenty infinite to install a shelf above the water heater.
One more condition: you lot tin alone install a shelf to a higher place an electrical water heater. A gas H2O heater or alternative fuel-fired H2O heater would live off-limits.
Don’t Store Combustible Materials Near Water Heater
You should never store combustible materials, such as newspaper, chemicals, woods, etc., about the H2O heater because this poses significant a burn chance.
- Paper items are extremely combustible as well as should non live stored near a water heater. For example, books, magazines, of import papers together with documentation, medical records, taxes, nascency certificates, together with family photos are extremely flammable (not to refer that losing just about of these would be devastating!).
- Chemical items are extremely flammable as well as fifty-fifty explosive too should not be stored well-nigh a water heater. So things like your house cleaners, solvents to create basic acids, too paints for the walls should live kept good away from the heater.
- Woods such as firewood or onetime wooden antique article of furniture should not live stored well-nigh the H2O heater because, similarly to newspaper items, wood is extremely combustible. Furthermore, untreated or poorly maintained forest tin can innovate pests such equally termites or bring inward insects from outside, which could harm your H2O heater.
Even with an electric H2O heater, in that location may be sparks that class together with could movement a burn in the presence of these combustible material.

Consider What Would Be Damaged by Water
Water impairment is pregnant if non identified inward the early stages. Water harm oft is representing inwards the class of rotting forest, moldy walls, bacterial increase, extreme rust, too degradation of common family materials. You can intend of your domicile being damaged past water internally together with externally.
Internal H2O damage is oft due to H2O leakage from the H2O heater accumulating inside the abode together with flooding the room. This may crusade damage to whatsoever other appliances, such every bit brusk-circuiting washers, dryers, and vacuum cleaners, should they be stored virtually the H2O heater.
External water damage is ofttimes due to where the walls of your dwelling house go of the H2O heater having a leak. If the water heater is located on a non-earth degree floor, the water tin can saturate the below floor ceilings. Furthermore, the sidewalls volition become damaged due to the forest too insulation go moisture.
Ensure Nothing Blocks the Air Flow
There must be cypher that blocks the airflow into the water heater storage closet. This is because, without adequate combustion air, at that place is a take a chance of carbon monoxide product.
A ascension inwards levels of the flammable gas carbon monoxide increases the run a risk of ignition points causing a burn down in your household. Furthermore, carbon monoxide is a poisonous gas to humans too pets, together with may drive serious adverse health effects too even decease!
Thus, having more gratis infinite about the water heater agency that at that place is more than free-flowing oxygen together with carbon monoxide construct-up is less likely.
Do not shop items that tin can move about nearly the H2O heater. This includes items such as books, ironing boards, in addition to cleaning supplies. This is because whatever of these items may fall without your knowledge and block the airflow vent of the H2O heater.
Can You Store a Refrigerator by a Water Heater?
It is best not to store a fridge by a H2O heater for several reasons.
Firstly, a H2O heater is a source of oestrus, whereas a fridge is a beginning of frigidity. If a rut origin is nearby all of the chilled food, the refrigerator will take to go twice as hard to proceed all of the chilled nutrient common cold, increasing your electricity bills.
Secondly, the water heater may sometimes need to live switched off either due to leakage or maintenance. You make non desire the fridge to live hooked onto the same outlet which may become switched off. Otherwise, all of your nutrient volition spoil.

Can You Store a Dryer by a Water Heater?
Do non store a dryer past a water heater No other fuel-burning appliance should live installed inwards the same confined area equally a dryer (such every bit a cupboard) because it introduces the possibility of at that place not being adequate ventilation for both applications.
Furthermore, lint from the dryer may make upwards together with, amongst the heat too fuel of the H2O heater, this tin lead to burn down too fifty-fifty explosions.
However, if this is non a minor storage cupboard merely rather a big basement amongst air ventilation, then a dryer tin can live stored within the vicinity of a water heater, provided at that place is still a reasonable clearance distance.
Regularly Check That Clearances Are Correct
You call for to regularly bank check that clearance distances are correct if yous are storing family items near a H2O heater. This is because these items may move closer over time due to fry earthquakes or home members unaware of regulations too moving items around.
A style to regularly check that clearances are right is that the offset time yous are measurement the right clearances from the H2O heater, you tin can place bright tape on the floor where the other items should be placed. Then, every calendar month, y'all can check if these items are behind the colored record.
How to Safely Enclose Your Water Heater
A H2O heater tin be enclosed just it is important to know that there are specific weather that must be achieved when placing a hot H2O heater inside an enclosed infinite. This applies to both gas and electrical water heaters.
There are more safety concerns when running a natural gas line into your home. For a gas water heater, you are at higher adventure of having carbon monoxide gas leaks which may upshot inward an explosion.
Proper maintenance must live applied to safely enclose this water heater and then that in that location is proper ventilation inside the enclosure in addition to regular accessibility and so that periodic checks on the gas line of work ensure proper role.
Electric H2O heaters do non take these risks, but instead, the hazard of an electrical fire.
- To safely enclose your water heater, you lot commencement ask to design the enclosure to tally whatever manufacturer’s instructions for clearances. This agency that there should be a buffer zone of spacing and then that you lot or a repair somebody tin get slow access for maintenance.
- Then the walls should be solid as well as framed to make sure they tin be long-lasting.
- Next, the doorway should be constructed then that at that place is proper ventilation too slow access.
- Lastly, the enclosure should be finished by painting with primer.
Go Tankless to Save Space
In club to salve space, yous tin can also become tankless when choosing your water heater. The benefits of a tankless H2O heater include low energy consumption, extended lifespan, lower utility bills due to less energy compared to traditional storage H2O heaters, together with the possibility of a tax credit. More in-depth benefits tin can be found inward my article on the nine Benefits of a Tankless Water Heater.
The negatives of a tankless H2O heater are that at that place is the potential for overheating other menage appliances, overloading the electrical circuit, together with carbon monoxide poisoning. I accept also written an entire article on the Dangers of Tankless Water Heaters.

Clearances even so utilise because tankless water heaters function alongside electricity or gas, merely the actual units are smaller, and so they accept upwards less space.
Here are roughly tankless water heaters that you can take a await at:
- Rinnai Indoor Tankless Hot Water Heater (amazon link) – The Rinnai water heater is energy in addition to space efficient and only heats upwards when necessary for a 6.v GPM hot water menstruum rate.
- Camplux Outdoor Digital Display Propane Gas Tankless Water Heater (amazon link) – The Camplux H2O heater is slow to install (v minutes) and comes alongside all necessary accessories to ensure safety flame failure in addition to anti-freezing protection.
- Furrion Tankless Gas Water Heater (amazon link) – The Furrion H2O heater is high ability due to its 60K BTU heating ability together with a two.iv GPM capacity.
