Labor - Rixens MCS7 Hydronic Heater Retrofit Installation | 2021–2024 Winnebago Revel

ODB removes your Revel's factory Timberline heating system and installs Rixens MCS7: cabin heat and hot water that adjust automatically for altitude. Fully commissioned and leak-tested.

Timberline out. Rixens MCS7 in. Commissioned before you pick up.

We remove the factory Timberline heating system from your 2021–2024 Revel and install Rixens MCS7 in its place. You get cabin heat and hot water from a system that compensates automatically for altitude, controlled from one touchscreen or your phone. We're Colorado's Winnebago Revel and Ekko specialists, and this is a Revel-specific retrofit.

Why upgrade a 2021–2024 Revel

• Automatic altitude compensation. The MCS7 measures air pressure and adjusts combustion on its own, to at least 11,000 ft (Rixens spec). No altitude kit or manual setting.
• Phone access and diagnostics. Control the MCS7 from your phone's browser over its own Wi-Fi, no app or internet needed. The touchscreen shows furnace hours, altitude and stored fault codes.
• Stepless heat. The Eberspächer Hydronic S3 modulates from 1.3 to 5.0 kW and burns as little as 0.15 L/h at low demand.
• Engine heat option. Add engine heat recovery and engine preheat to the same system, now or later.
• Facing a burner repair? If your Timberline needs a burner replacement or major repair, compare that cost with moving to the MCS7.

What we do

1. Inspect We check coolant condition, the fuel pickup, exhaust and the existing hydronic components. Anything pre-existing that needs repair is quoted before work starts.
2. Remove the factory Timberline burner, control panel and other components the retrofit replaces.
3. Install the MCS7 furnace, power box, touchscreen controller, two-speed glycol pump and kick-space air handlers.
4. Re-integrate the coolant reservoir, domestic hot water heat exchanger and mixing valve. These carry over from the factory system.
5. Route and adapt coolant, fuel, exhaust, intake, domestic water, air heat, electrical and control lines for clean integration and service access. We replace the exhaust pipe, muffler and aged flexible fuel line, and keep the hard fuel lines, which meet S3 requirements. The factory 1,500 W, 120V electric element is reconnected to the MCS7 control board.
6. Configure cabin heat and hot water in the MCS7 controller. Altitude compensation is automatic.
7. Commission: vacuum-fill the coolant loop to pull the air out and check for leaks before coolant goes in, prime fuel, run the system, leak-check every connection and function-test heat and hot water.
8. Hand off: a walkthrough of the touchscreen and phone access at pickup.

The installed project

Not included: the MCS7 kit and materials (priced above), and repairs to pre-existing vehicle, plumbing, fuel, electrical, cabinetry or hydronic issues unless quoted separately.

Add engine heat while we're in there. Engine heat and preheat integration adds a dedicated heat-exchanger loop between the engine and the heater. The two coolant circuits stay separate. It recovers engine heat while you drive and can preheat the engine from the touchscreen before a cold start. Added during this retrofit, its installation costs 25% less: choose Bundled Install on the installation page and add the Engine Heat & Preheat Integration Kit.

Fits: 2021–2024 Winnebago Revel with the factory Timberline diesel hydronic system. Final requirements can vary with vehicle condition, prior modifications and production-year differences. We confirm them during quote review.

FAQ

How long will my van be here?
About a week. We confirm your install window during quote review.

Can I supply my own parts?
No. We install only parts we source, so we can stand behind the result.

What could change the final price?
Coolant and installation materials are estimated during quote review and depend on your van's routing and condition. Pre-existing issues we find during inspection are quoted separately before any work is done.
