Project Ideas

Business

Full-Service Tankless Installation & Sizing

Offer a local service that handles on-site load calculations (use GPM and ground water temperature), permits, professional installation (indoor/outdoor with Versa Vent), and commissioning of Rinnai units. Upsell options: WiFi Controlr module, RX-OVC outdoor cap, and extended warranties. Emphasize compliance with codes and recommend Rinnai PRO-certified technicians.


Subscription Preventive-Maintenance Plans

Sell annual or biannual maintenance contracts focused on the unit’s Quick Flush routine, condensate trap checks, and vent inspections to preserve the UEF .98 efficiency. Offer tiered plans (basic inspection, premium cleaning + priority service) with automatic scheduling and digital reminders, generating recurring revenue and reducing emergency callouts.


Energy-Upgrade Consulting & Rebate Assistance

Package energy audits for homeowners and small businesses that recommend replacing older tanks with high-efficiency tankless systems. Provide payback analyses using GPM usage patterns and local ground water maps, identify available rebates or incentives, and manage rebate paperwork to close sales faster.


Rental/Temporary Hot Water Solutions for Events & Sites

Provide short-term tankless hot water rentals for outdoor events, construction trailers, or pop-up food vendors (installed and removed by pro technicians). Market the compact size, high GPM capacity (up to 11.1 GPM), and propane option for sites without natural gas. Ensure all installations meet local codes and include on-site tech support or training.


Hands-On Training Workshops & Demo Room

Set up paid workshops for plumbers, builders, and savvy homeowners demonstrating sizing, installation best practices (indoor vs. outdoor with Versa Vent), maintenance, and WiFi Controlr integration. Keep a non-operational demo unit for teardown/reassembly so attendees can practice safely; sell starter kits, parts, and service vouchers at the class.

Creative

Industrial Wall Art (using a decommissioned unit)

Turn a decommissioned Rinnai unit or its outer casing into an industrial-style wall sculpture. Clean and prep the silver housing, mount it on a reclaimed-wood backer, add battery-powered LED strips behind vents for backlighting, and stencil a simple schematic or brand plate for a tech-meets-vintage look. Important: this uses non‑operational units or parts — do not attempt to display a live gas appliance or alter gas/electrical connections.


Vent Pipe Pendant Lamps (from spare venting pieces)

Repurpose unused Versa Vent pipes, caps, and fittings into a series of pendant lamps with an industrial aesthetic. Cut and polish vent sections, assemble into staggered pendants, and wire with low-voltage LED sockets or lamp kits. Use only retired venting parts or new spare vent components and follow safe metalworking practices; do not modify an installed or functional heater.


Educational Demo Station for Efficiency

Create a hands-on display that explains tankless vs. tank water heating using the unit as a visual centerpiece (non-operational). Accompany it with charts, a touchscreen or laminated cards showing UEF .98 benefits, GPM examples, and local ground water temp impact. This is great for maker-spaces, trade shows, or community energy nights — keep the appliance disconnected and labeled 'demo only.'


Packaging Upcycle: Insulated Cooler or Tool Crate

Use the unit’s original insulated packaging materials and foam inserts to craft a heavy-duty cooler or insulated transport crate for cider, camping food, or temperature-sensitive tools. Reinforce with plywood, add handles and drainage, and finish with durable paint or sealant. This repurposes high-quality insulation without touching the live appliance.
