Your options

What makes a manufactured home heater different

We look at the cause, the condition of the existing system, and what will work best for your property.

01

Listed for the use

Federal manufactured home standards require appliances to be listed or certified by a nationally recognized testing agency, and fuel-burning heaters to be vented to the outside. The replacement has to meet those rules, not only fit the space.

02

Sealed combustion for gas

A gas heater inside the home has to keep its combustion separate from the air in the home, typically with a direct-vent (sealed combustion) unit or a sealed enclosure. Swapping in a standard atmospheric heater is not a like-for-like replacement.

03

The closet sets the size

Many manufactured homes have the heater in a small interior closet or an exterior access door. The new heater has to fit, stay accessible, and be removable, which narrows the choices.

Around the Valley

Seasonal homes in Mesa and Apache Junction

If the home sits empty in summer, turn the heater off or to its vacation setting and close the water supply before you leave. When you come back, open the water, check the closet floor for leaks, and turn the heater on only once the tank is full.

Planning the work

What affects the price

Gas or electric, and whether a sealed-combustion gas unit is needed
Tank size that fits the closet and access door
Venting, drain pan, and relief line condition
Floor or closet repairs found when the old heater comes out
Access from inside the home or an exterior door

What the federal standards say about manufactured home water heaters

Manufactured homes are built to the HUD code, 24 CFR Part 3280. Its rules for heat-producing appliances and their installation include these points for water heaters:

Appliances must be listed or certified for residential use by a nationally recognized testing agency (3280.707(a)).
Fuel-burning appliances other than ranges and ovens must be vented to the outside (3280.707(b)).
Each appliance must be both accessible and removable (3280.709(a)).
Fuel-burning appliances need complete separation of the combustion system from the interior air, met by direct-vent (sealed combustion) appliances or an enclosure (3280.709(d)).
A corrosion-resistant drain pan goes under a storage-type water heater (3280.709(h)).

Common questions

Before you schedule

Can I put a regular water heater in a mobile home?

Not always. Federal manufactured home rules require listed or certified appliances, gas heaters vented to the outside, and sealed combustion or a sealed enclosure for gas units inside the home, so the replacement has to match those requirements and fit the closet.

Do you replace water heaters in 55+ and RV parks?

Yes, for manufactured homes in parks and communities across Mesa, Apache Junction, and the Valley. Let us know about any park rules for access or work hours.

Gas or electric for a manufactured home?

Usually the same fuel the home has now, since switching can mean new gas piping or a new circuit. We explain what a change would involve.

Does a manufactured home heat pump water heater qualify for SRP's rebate?

SRP's terms say mobile homes are eligible when the heater and installation meet the rebate's other requirements. Check SRP's page for current terms.
