CheapHeat Standalone CheapHeat Ductless

Until now, the standard for recreational vehicles of all types has been to use bottled propane (LPG). With the CheapHeat™ system that’s no longer the only option - now you have a choice to change the central heating system between gas and electric with the simple flip of a switch. When you choose to run on electric heat, rather than gas heat, your coach will be heated by the electricity provided by the RV Park.

With the CheapHeat™ system it’s not uncommon for even "full timers" to go up to one year or more without having to refill their propane tanks. Now the propane is only being used for incidentals like the stove, or in some cases the hot water.

CheapHeat Ductless CheapHeat Ductless

The CheapHeat™ NT-DH19 Add-on Electric Heater, is designed work with the Suburban Direct Discharge Gas Furnace models NT-12, NT-16, or NT-20. These furnaces are commonly found in Tent Trailers and Pick-up Campers. The CheapHeat™ electric heater frame, fits between the grill and the mounting flange, onto the end of the direct discharge gas furnace, is unique in its manufacture because the heater controller is built inside the frame. This new self contained design simplifies the installation process, by eliminating the need for additional wiring, and controls external to the heater.
As with all RV Comfort Systems products this heater kit is UL certified and RVIA compliant. Because of the NT-DH19 open wire electric coil, and hollow frame design it offers virtually no backpressure to the Gas furnace fan. In fact, the electric heater and frame has more than 4 times the free air passage of the original gas furnace grill that is provided by the furnace manufacturer. For additional safety the heater is protected by an auto reset 140 F degree high limit switch backed up by an inline 262 F degree High temperature fusible link failsafe, which is connected directly to the heater coil itself.

Technical

The CheapHeat Ductless system operates off ofa 20 amp 120 VAC breaker via its internally mounted controller consisting of UL certified PC Board, with a DPST relay rated 240 VAC, 30 amps, which turns the 16.5 amp 120 VAC electric coil on and off. The second relay is a SPST rated at 12 VDC, 10 amps which turns the gas furnace fan motor (2.8 amps @ 12 VDC) on and off in tandem with electric heater relay. The SPDT 12 VDC override switch is mounted to the access panel cover, and is used to switch the thermostat between the onboard heater controller and the gas furnace PC board. When the switch is in the Electric Heat mode the gas furnace controls are bypassed, and NT-DN19 electric element and furnace fan will turn on and off in accordance when the room thermostat call for heat. When the override switch is in the Gas Heat mode, the room thermostat is connected back to the gas furnace PC Board, and the gas furnace will operate as it did before the electric heater was installed.

Compatibility

Works On: The NT-DH19 is designed to work with the Suburban NT-12, NT-16, and NT-20 Series direct air discharge RV Gas Furnace.

Output: Because a RV Gas furnace is only about 60% efficient (40% of heat goes out the flue) and it has a pre-purge (60 seconds) and post-purge (90 Seconds) cycle of approximately 2 ½ minutes for every heating cycle. The overall output during a given heating cycle is reduced as follows:

Gas Furnace CheapHeat
Input
12,000 btu
16,000 btu
20,000 btu
True Output
5,600 btu
*7,600 btu
*9,600 btu
Input
6,657 btu
True Output
6,657 btu

* Note: When calculating heater run time on any average RV, it is assumed (industry standard) that the total run time will be somewhere between a 25% to 75% duty cycle, depending on outdoor temperature. By increasing run time with the CheapHeat™ system, the consumer can exceed the heating capacity of the 12,000/16,000 btu gas furnace’s and meet 86% of the 20,000 btu gas heaters output.

Application Graphics

This heater is very compact and only adds 1 ¾” in additional length to the front of the furnace, when installed between the grill and the furnace flange. Also, because of its compact design it doesn’t require any modification around the opening for the furnace, accept two holes on the right hand side. One for the 120 VAC feed, and one for the 12 VDC low voltage plug.

CheapHeat AddOn CheapHeat AddOn
There are two different configurations that manufacturers use when installing central heating in a Recreational Vehicle. The first way is shown in the above left picture and is called a plenum system trunk line fastened directly to the furnace with floor registers). The second way is shown in the above right picture and is called a ducted system (individual ducting runs of 4” pipes). In both cases, the CheapHeat™ Add-On system consists of the Remote Override Switch and the following components:
CheapHeat AddOn The CheapHeat™ Add-On cabinet houses the new electric heating element and comes in multiple designs to provide the air flow needed to maintain long-term operation, while addressing various installation clearance problems. There is one cabinet style for SF, SH, and Atwood ducted systems, but for plenum systems, there are two cabinet styles needed. Because of this, there are specially designed inserts that make it compatible with both SF and SH model gas furnaces. (See compatibility chart.)
CheapHeat AddOn The CheapHeat™ Add-On electric heater element is specially engineered so that a single element can be used in multiple configurations and capacities. This allows the installing dealer to provide a maximum amount of options to their customers with a minimum amount of inventory. The DH Model elements are designed to fit in any of the six different cabinet configurations. Check the compatibility chart on the back of this brochure to select the proper element configuration for your RV.
CheapHeat AddOn The UL listed CheapHeat™ controller is the heart of the system. It is used to redirect the thermostat communications to the heating source of choice (gas or electric), to operate the electric heating element, and to manage the gas furnace fan motor. In the gas heat mode it communicates with the existing gas furnace and manages two operations. One is to feed a signal to the gas furnace PC board when the gas heat option is selected. The other is to operate the fan motor to supply air across the electric coil as needed when the electric heat option is selected with the override switch. In the electric heat mode, it operates the electric heating element, while at the same time taking over the operation of the existing gas furnace 12 VDC fan motor to supply air across the electric element during the heating cycle. Additionally, when the model DH18-120 electric heaters are used, the controller manages the fan speed as well to help reduce noise and improve comfort-level.

Features

Adaptable to Multiple Configurations
The CheapHeat™ system has been designed to provide a maximum amount of configurations with a minimum amount of equipment. Our model CH-50 Controller is engineered so that it can operate with both 30 amp and 50 amp shore power inputs. Additionally, the controller works with a specially designed heating element that provides the customer the ability to pick from 3 different heating outputs from one heater element. As well, the add-on cabinet is designed to accommodate 6 different cabinet configurations with only 3 different cabinet styles. (See Compatibility Chart)

Automated Operation
Because of the advanced design, the CheapHeat™ CH-50 controller integrates seamlessly with the existing gas furnace printed circuit controller and thermostat. Once installed, the only additional control the customer will have, is a switch that gives them the ability to select whether they want to heat their RV with gas or electric.

Convenience
The CheapHeat™ allows the RV owner to have uninterrupted heat for their RV, when their hooked to its manufacturers recommended shore power, without having to use gas, or worry about running out of gas (LPG). This means no having to pull up stakes during a vacation to get your propane refilled.

Dependability
When using the CheapHeat™ electric heating option you don’t have to worry about the gas furnace igniter failure, jets clogging, or spider web problems that are inherent when using LPG gas furnaces. With the electric element providing the heating to the RV, the only moving part outside of the controller is the fan motor in the gas furnace.

Freeze Protection
One of the long standing problems an RV owner has faced is how to keep their pipes from freezing without going out every few days to refill the propane. With the CheapHeat™ system, when the system is in the electric mode, there is no propane use for heating, so you don’t have to worry about running out.

Improved Safety
When it comes to safety there are at least 3 areas the CheapHeat™ system really shines:

  1. If you’re NOT using gas heat you don’t have to worry about the furnace causing monoxide poisoning.
  2. You don’t have to worry about a 1500ºF flame burning inside a metal cabinet in your RV.
  3. There is no need to use unsafe portable electric heaters to supplement your heating, or freeze protection.

The CheapHeat™ system is also failsafe protected, with four internal safeties:

  1. Auto reset air temperature switch used to control discharge air temperature.
  2. High temperature fusible link that disconnects permanently at a preset high temperature (well below the temperature the even paper starts to turn brown).
  3. In-line manual reset breaker that controls any over current problems.
  4. All wiring and components are oversized by at least 30% with respect to the actual load requirements.

Increased Comfort Level
Because the manufacturer installed gas furnace generates such high air temperatures as the air travels across its firebox, it has a tendency to generate high discharge air temperatures. This leads to over shooting the thermostat setting by getting the coach air to hot before it shuts off and then allowing it get to cool before it comes back on. When the CheapHeat™ system is in the electric heating mode you’ll find that the heated air temperature is cooler, allowing longer run time, which does a better job of mixing all the air in the coach, as a by product, the RV maintains a more comfortable temperature throughout the coach.

Offers Peace of Mind
With the CheapHeat™ system the RV owner has the peace of mind in knowing that when they need the heat they won’t run out of propane. You don’t have to worry about monoxide poisoning from the furnace. You don’t have to worry about it not working because of igniter or spider web problems, and most importantly, you don’t have to worry about your RV catching fire because a portable heater tipped over, or it overheated a wall socket.

U.S. Patent Protected
The CheapHeat™ system has been registered with the U.S. patent office to protect its customer from fakes and imitations. As a patented product, you can be confident that a thorough search has been made at the U.S. Government archives, to insure that the CheapHeat™ system is not an uncertified spin-off of some other product.

Reduced Operation Cost
This is where the CheapHeat™ really shines. Rather than having to pay for propane (LPG) to heat your RV, the RV owner can now just plug the RV into shore power at their favorite RV Park. Then turn the CheapHeat™ override switch to ELEC and bingo, free heat, because most all RV parks include electrical, as part of their daily/nightly space rent.

Reduced Noise Level
With a gas furnace, during the warm up and cool down process, the firebox makes snapping, cracking and popping noises. This is because of the extreme temperature changes happening inside the firebox. When using the CheapHeat™ system in the electric heat mode, none of these temperatures are exposed to the firebox so, no noise. Additionally on the DH18-115 & PL18-115 models the controller actually reduces the fan speed to help decrease noise levels and increase comfort levels.

Reduced Fire Hazard
When operating the CheapHeat™ system in the electric heat mode, you no longer have to worry about having a portable heater tip over and cause a fire, or having it overheat and set the wall socket on fire. You don’t have to worry about a possible gas explosion, that may have been caused by a gas furnace misfiring. But most importantly, you won’t have to worry about some manufacturer not installing your SH model furnace correctly, causing the flue pipe to burn the outer wall of the RV.

Reliability
The CheapHeat™ system has been designed for durability and reliability, above and beyond industry standards. As an example, the control relays are all 30% plus oversized. The circuit board is double layered with 30% oversized copper connections and it is mounted in an industrial grade electrical box. The electrical element is designed to be used in the most rugged conditions, and has been drop tested from three feet, with no damage. Additionally, as an electrical supplied heating system, it has a minimum amount of moving parts, compared to a gas heater. There is no metal firebox to rust out when you use a tungsten electrical coil to heat with. All of that being said, if your RV Park does have a power outage, just flip the override switch and you’re back on gas heat.

UL® Listed Components
All of the component parts in our CheapHeat™ controller are UL® Listed, as well as the Printed Circuit Board and its manufacturing process have been UL® Listed. All of those components and PC Board are mounted in an industrial grade NEMA-1 UL® Listed and certified metal box to make a completed controller.

CheapHeat Standalone

The CheapHeat™ Stand-A-Lone all Electric Forced Air Heating system is designed primarily for Park Model Trailers, but can be used on coaches where there is not enough room to install our Add-On system to an existing gas furnace. The new system DOES NOT require a gas furnace to be hooked inline with the electric heater. It has its own fan, with cabinet, and works with the current CheapHeat™ Controller and Electric heater. This system is UL certified and RVIA compliant in both the United States and Canada.

The Stand-A-Lone system consists of a multi position combination ducted/Plenum cabinet that allows the tri-stage heater element to be installed from either side, to allow users to use this new system in multiple locations. One of the best new features is that with the new Stand-A-Lone electric forced air heating system the manufacture is no longer required to place the furnace next to an outside wall for venting. This gives the coach manufacture more flexibility in their floor plans.

Technical

When talking about heat output, remember that a gas furnace is only 60% efficient, 40% of the heat goes out the flue. But an Electric heater has no flue so it is 100% efficient. This means a 40,000 BTU an hour furnace has only 24,000 BTU an hour output.

Additionally, a gas furnace has a 60 second pre-purge cycle and a 90 second post-purge cycle. Which means that for every heating cycle, there is 2 1/2 minutes of run time with no flame (heat). After taking into consideration the 2 1/2 minutes of no fire each heat cycle, along with the efficiency issues your true output into the coach with a 40,000 BTU gas furnace, is about 18,000 BTU an hour when measured at the register. The 100% efficient CheapHeat™ DH50 has a true 17,500 BTU an hour output to the register (Add-On or Stand-A-Lone).

The best way to explain it is if you measure the temperature at the floor register the electric heat output is +/- 5 degrees of what a gas furnace puts out (depending on the length of the ducting).

Heater Configurations
The Stand-A-Lone system (CH50-SAL) provides the same amount of heat as the Add-on System:

  • CH50-DH50: Comparable to 40,000 BTU Gas furnace (Requires 50 Amp Service)
  • CH50-DH37: Comparable to 30,000 BTU Gas furnace (Requires 50 Amp Service)
  • CH50-DH18: Comparable to 20,000 BTU Gas furnace (Requires 30 or 50 Amp Service)

Dimensions

  • Height: 10 in.
  • Width: 17 1/2 in.
  • Depth: 19 in.

Clearance From Combustibles

  • Top: 1 in.
  • Side (w/ Heater Head): 3 in. (To allow clearance for electrical access)
  • Side (w/o Heater Head): 1 in.
  • Front (w/ 4” Duct): 6 in. (To allow connection of 4" round ducts)
  • Front (w/o Duct): 1 in.
  • Bottom: 0 in.

Electrical

  • DH50: 21 amps per leg on 50-amp service (about the same as 2 roof AC)
  • DH50: Leaves 29 amps per leg to run the coach (58 amps at 120 VAC to run the coach)

  • DH37: 16 amps per leg on 50-amp service (about the same as 2 roof AC)
  • DH37: Leaves 34 amps per leg to run the coach (68 amps at 120 VAC to run the coach)

  • DH18: 16 amps per leg on 30-amp service (about the same as 1 roof AC)
  • DH18: Leaves 14 amps to run the coach (14 amps at 120 VAC to run the coach)

  3. Inline manual reset breaker that controls any over current problems.
  4. All wiring and components are oversized by at least 30% with respect to the actual load requirements.

Comfort
The Stand-A-Lone electric heat system eliminates the 60 sec pre-purge and 90 post-purge processes for every heating cycle.

The RV owner no longer has to put up with the “it’s too cold or too hot syndrome”, caused by the fan on the gas furnace running with no heat being produced.

Peace of Mind
With the CheapHeat™ system, the RV owner has the peace of mind in knowing that when they need heat they will have it, and will not have to worry about running out of propane.

The RV owner does not have to worry about monoxide poisoning from the gas furnace. They do not have to worry about the gas heat not working because of igniter or spider web problems, and most importantly, they do not have to worry about their RV catching fire because a portable heater tipped over or overheated a wall socket.

Q: How cold can it be outside and still heat with CheapHeat™?
A: That depends on the CheapHeat™ model selected and the RV. There are "full timers" who keep their large coach at 72º F inside, when it is as cold as 10º F outside.
Q: Will it work in my RV?
A: It can be installed in the majority of RVs that have a central forced air heating system, with clearance for the add-on components.
Q: Where do I get it installed?
A: The CheapHeat™ system needs to be installed by a certified RV repair facility. You can contact RV Comfort Systems for a dealer near you.
Q: How do I know which adapter fits on my furnace?
A: Check the “Compatibility Chart” hyperlink on the bottom of the “FAQ” page. There are three styles of add-on cabinet adapter (SA-7 and SA-9 for Ducted Systems), (PL-7 and PL-9 for Plenum Systems), (AT-10 for Ducted or Plenum on an Atwood 8500 Series).
Q: Where do I find the “Compatibility Chart”?
A: Go to rvcomfortsystems.com and click on the “Compatibility Chart” hyperlink at the bottom of the “FAQ” page.
Q: Does my RV need 30-amp or 50-amp shore power?
A: The DH18-37-50 electric heater assembly is a multi tap heater. When configured as a (DH-18) it can be used on a 30 amp or 50 amp service. When configured as a (DH-37) or (DH-50) is must be connected to a 50 amp service.
Q: Can I upgrade my RV from a 30 amp service to a 50 amp service?
A: YES, It can be usually be performed by a qualified electrician for a couple hundred dollars. If you e-mail info@rvcomfortsystems.com and request our 30 amp to 50 amp upgrade document we will send you detailed information on how it's done.
Q: How do I measure the clearance measurements?
A: All measurements are taken inside the RV, when measuring the added length measurement, measure from the end of the furnace towards the center of the coach. With the ducted system make sure to allow enough room to reconnect the ducts on to end of new add-on cabinet. For the added height measurement, measure from the top of the furnace extended out to where the cabinet adapter is attached. For the side, determine which side the high voltage is connected to the heater and allow a minimum of 2 ¾” (AT-10 allow 1 inch on the opposite side as well).
Q: Do I need a fully functional gas furnace to install the CheapHeat™ Add-on System?
A: The furnace does not have to be fully functioning for the electric heater to work. But the blower fan MUST be working and in good repair.
Q: Will the Stand-A-Lone furnace fit in place of my old Gas furnace?
A: In 95% if the cases the Stand-A-Lone Electric forced Air furnace will fit in the same foot print as the old gas furnace. However, measurements should be made to confirm that space is available. The SAL furnace is (10” H x 17 ½” W x 19 ½ “ L).
Q: Can I use the Stand-A–Lone furnace with my existing gas furnace?
A: NO, it's either, NOT both.
Q: What’s the difference between the Direct Discharge system and the Ducted system?
A: A Direct Discharge furnace is usually found in a Tent Trailer or Pick-up Camper and does not have any 4” round ducts or plenums attached.
Q: Can I install the Direct Discharge system on a ducted system?
A: NO, it is designed to work with the Suburban NT-12, NT-16, or NT-20 Series direct discharge gas furnaces.
Q: If I have a system installed in a RV with a 50 amp shore power system, what happens if I adapt my 50 amp service to plug into a 30 amp service?
A: The CheapHeat™ System has a Smart Controller, which will not allow the heat to come on when a 50-amp service is adapted to run on a 30 amp plug. The only thing that happens is that the fan will run with no heat because if the heat came on it would overload the circuit.
