Installation: Condensate Piping

Commercial heat pump water heaters can produce large amounts of condensate

during warmer weather; in cold climates they will also create condensation runo

during the defrost cycle. It is imperative that both high volume summer runo and

freezing temperature water handling are both considered in the condensation

management plan.

A drain pan is installed under the evaporator coil. The pan includes water level

sensors, trace heating, and a connection point for exterior condensate piping.

The heat pump will suspend compressor operation when enough water is present

in the drain pan, and will initiate pan heating if the ambient temperature poses a

freeze risk when water is present in the pan.

Nyle recommends all condensate lines be piped to drain. Failure to

control condensate can result in slip/fall conditions, site erosion,

water damage, and/or damage to the heat pump water heater itself;

which can include complete unit failure not covered by warranty.

While unpiped applications are possible, they would need to be

able to safely accommodate signiﬁcant and sustained condensate

production, especially in humid climates. Unpiped applications would

also require a mounting height of 12-24” (dependant on local climate)

to avoid ice damage to the heat pump in freezing conditions, as well

as routine inspection to ensure ice buildup doesn’t threaten the unit.
