Renting a hot water boiler can keep your facility running during an emergency or provide temporary capacity during construction. But too often, facilities waste time and money by overlooking important details. Choosing the wrong system can delay installation, create safety risks, and drive up operating costs.
At WARE, we help facility managers, construction teams, and healthcare leaders avoid these pitfalls every day. Here are five of the most common mistakes we see, and how WARE’s steam and hot water boiler rentals keep you covered.
Mistake #1: Not Having Key Boiler Specs Ready
One of the fastest ways to slow down your rental process is not knowing the basic details of your system. Before requesting a hot water boiler rental, you should know:
- Required BTUs
- Supply and return temperatures
- Flow rate
- Desired temperature rise
- Available fuel type (natural gas, propane, diesel)

When you have these specs ready, our team can size and ship the right unit faster, reducing downtime and keeping your project on schedule. Check out our formulas and measurement guides to find your specs.

Mistake #2: Confusing Hydronic and Domestic Hot Water Needs
Hydronic hot water is for heating buildings and processes. Domestic hot water is potable water used in sinks, showers, and food service. They are not interchangeable. Mixing them up can lead to contamination and issues with compliance.
WARE's Safe, Dual Water Supply Units
WARE’s rental systems are designed with plate and frame technology that keeps loops separate, ensuring potable water stays safe while hydronic systems run efficiently.

Mistake #3: Using Mild Steel in Domestic Applications
Domestic water is oxygen rich, which causes mild steel to corrode and contaminate potable water. Unfortunately, some rental systems still use mild steel in domestic applications.
WARE never cuts corners.
Our domestic hot water rental boilers are built with stainless, brass, and bronze components only, giving you clean, safe water you can trust in healthcare, food service, and residential support facilities.
Mistake #4: Overlooking Freeze Protection
Temporary hot water construction sites and outdoor facilities often face freezing conditions. Without protection, rental systems can fail when you need them most.
Glycol Loops Prevent Freeze
WARE’s hot water rentals include glycol loops and freeze-resistant designs that keep systems running reliably in cold climates and outdoor installs. This is especially critical for construction projects in winter or facilities with exposed piping.
Mistake #5: Not Planning for Fuel Flexibility
Construction schedules change. Emergencies happen. The fuel you planned for might not be available on site. If your rental cannot adapt, you are stuck.
WARE’s hot water rental boilers are designed for flexibility. With quick-change burners, you can swap between natural gas, propane, and diesel in as little as 20 minutes. That adaptability keeps your project moving even when conditions change.
WARE Helps You Plan For The Unexpected
For maximum protection, WARE also offers a Rental Contingency Plan. A contingency plan ensures your facility has guaranteed access to the right equipment when unexpected issues arise, giving you confidence that your operations will not stop due to fuel or system limitations.
Why Mistakes in Hot Water Rentals Are Costly for Industrial Operations
Every mistake in a rental decision translates to lost time, higher costs, and real risk for your business. For manufacturing plants, food processors, and other industrial facilities, even a few hours of downtime can halt production and disrupt supply chains.
