When faced with limited vehicle space, many people wonder if a hot water heater can be transported on its side. While the appliance is a large, cylindrical metal tank, it contains delicate internal components that are not designed for horizontal movement. Transporting a water heater on its side is generally discouraged, but it is sometimes necessary, and when it is, specific precautions must be taken to minimize the risk of damage.
The Manufacturer’s Stance
Manufacturers recommend that a tank-style water heater be transported in an upright, vertical position. This recommendation is based on the internal design of the appliance, which is engineered for stability when standing. The packaging for a new unit is specifically designed to support the heater’s weight and protect its components during vertical movement and storage.
The internal parts, such as the dip tube and the anode rod, are secured to function correctly in an upright orientation. The dip tube, which delivers cold water to the bottom of the tank, is a long, rigid plastic or metal pipe that can be stressed or dislodged if the unit is laid flat. The entire structure is balanced to handle the weight distribution vertically, which is why the default instruction is to keep the unit standing.
Potential Damage from Laying it Down
Transporting a water heater horizontally introduces several risks that can compromise the unit’s longevity and performance. One significant concern is damage to the glass lining, a thin layer of porcelain enamel that protects the steel tank from corrosion. When the heavy tank is laid on its side, the weight distribution changes, which can cause the lining to crack or chip, leading to premature rust and failure of the tank over time.
The internal insulation, often a layer of polyurethane foam, can also shift or compress when the unit is placed on its side. This shifting creates voids or “cold spots” between the inner tank and the outer shell, which reduces the heater’s thermal efficiency and increases energy consumption. Furthermore, external components like the gas control valve, the temperature and pressure relief (TPR) valve, or heating elements can be struck or bear weight, leading to misalignment or breakage.
The Proper Way to Transport a Water Heater
The safest method for moving a water heater is to keep it upright using a hand truck or dolly. The unit should be secured to the dolly with straps to prevent rolling or shifting during transit. If the water heater is used, it must be completely drained of water before moving to reduce weight and prevent internal water from damaging components.
If horizontal transport is the only option, the unit should be laid on the side opposite the control panel and any delicate valves. It is important to use thick padding, such as blankets or foam, to cushion the entire length of the tank and prevent the outer shell from denting. The heater must be tightly secured with ratchet straps to a flat surface in the vehicle to prevent movement or jostling, which is the primary cause of internal damage.
Preparing the Heater for Installation
Once the water heater has reached its destination, it should be immediately returned to an upright position. A visual inspection should be performed to check for any external damage, such as dents or broken valves, before proceeding with installation. This inspection is a necessary step to catch any issues caused by the move.
If the water heater was transported on its side, a waiting period is necessary before filling the tank or connecting the power or gas supply. This waiting time, typically one to two hours, allows any shifted internal components, such as the insulation foam, to settle back into place. For hybrid heat pump models, this waiting period is even more important, as it allows the refrigerant and oil in the compressor to stabilize before the unit is energized.
