Quick answers

Does PTC heat replace a propane furnace?
PTC heat provides quick warm-up in cool weather; keep a properly sized furnace for freezing conditions.

Can I use it with an existing duct system?
Yes, when the ducted variant is selected and the RV duct layout is compatible.

What electrical load does the system use?
Cooling uses 1,550W input and the PTC heat strip uses 1,800W input on the specified 115V circuit.

18K COOLING + PTC WARMTH

High summer output with quick electric heat

This model keeps the 18K cooling platform and adds a small heat strip for mild conditions.

Recover larger cabins in summer heat

Higher output helps after long sun exposure when the entire RV interior has stored heat.

Cool hard, then reduce airflow

Adjust airflow after the cabin reaches a steadier temperature.

PTC OR HEAT PUMP?

Choose PTC for brief, mild warmth

PTC adds convenience, while a heat pump or furnace handles more sustained heating demand.

1
Hot summers remain the priority

The product is still primarily an 18K cooling system.

2
You camp with shore power

The 1,800W heat strip uses the 115V circuit for mild warmth.

3
You retain a furnace for winter

Pair this rooftop PTC system with the RV furnace for freezing-weather heat.

CHOOSE THE RIGHT MODEL

Choose around heating demand and sound

All three models cool well; the meaningful difference is how you heat and how the ceiling is built.

QUICK ANSWERS

Quick answers about PTC warmth, cooling and power

Quick guidance on rooftop fit, PTC warmth and electrical planning.

Does PTC heat replace a propane furnace?

PTC heat provides quick warm-up in cool weather; keep a properly sized furnace for freezing conditions.

Can it connect to existing ceiling ducts?

Yes, when the ducted variant is selected and the RV duct layout is compatible.

What electrical load does the system use?

Confirm the 115V circuit, breaker and wiring can support cooling and the 1,800W heating load.

Is the roof opening enough to confirm fit?

Also match the rooftop footprint, roof thickness, nearby hardware and ceiling assembly.
