When it comes to hot water boiler rentals, not all water is the same. One type of hot water keeps buildings warm and process systems running. The other provides safe potable water for sinks, showers, and food service. Mixing them up can lead to costly downtime, system failures, or even unsafe water.
Understanding the difference between hydronic hot water rentals and domestic hot water boiler rentals ensures you get the right solution the first time. At WARE, we design rental systems that keep both loops separate and contamination free, backed by 70+ years of expertise.

What Is Hydronic Hot Water?
Hydronic hot water is used for heating applications.
Hydronic water is never meant for drinking or washing. Its purpose is efficiency and heat distribution, not consumption. It circulates through coils, radiators, and building systems to provide consistent heat in facilities or on job sites. Hydronic hot water rentals are most often used in:
- Construction sites with temporary air coils for heating
- Facilities supplementing their heating systems during peak demand
- Industrial processes requiring consistent hot water circulation
What Is Domestic Hot Water?
Domestic hot water is potable water.
It's safe for drinking, cooking, cleaning, and sanitation. Rental systems that deliver domestic hot water must meet strict safety standards to protect water quality.
Common applications for domestic hot water boiler rentals include:
- Hospitals and healthcare facilities needing safe potable water during outages
- Temporary facilities requiring showers, sinks, and food service water
- Emergency replacements when existing domestic systems fail
Because people consume this water directly, safety is critical.
Why It's Important To Know The Difference Between Hydronic and Domestic
Confusing hydronic and domestic applications can lead to serious mistakes:
- Contamination: If potable and hydronic loops mix, oxygen-rich water corrodes mild steel and introduces rust into drinking water.
- Downtime: Incorrectly sized or specified systems cause delays in installation and operation.
- Safety risks: Unsafe water puts health, compliance, and liability on the line.
WARE’s hot water rental systems eliminate this risk by keeping hydronic and domestic loops separate with advanced plate and frame technology.
WARE’s Safety Standards: No Mild Steel in Domestic Systems
Domestic water is oxygen rich, which causes mild steel to rust and contaminate. That is why WARE never uses mild steel in domestic hot water rentals.
Our domestic systems are built with stainless steel, brass, and bronze to ensure safe, clean water every time. This standard is one of the key reasons facility managers, construction leaders, and healthcare teams trust WARE.

WARE’s new plate and frame rental system is designed for complex, real-world jobs:
