Heat Pump Water Heaters that are designed to save energy and money.

Heating should not be an afterthought in a heat pump chiller.

Engineers should not have to write their own control sequence, hunt for design-day answers, or figure out defrost on their own.

The new Nyle® Tero™ heat pump chiller series was built for both heating and cooling.

Tero provides published low-ambient performance data, coordinated defrost, controls that stage up to eight units, and support from selection through startup.

The result is the easiest heat pump chiller to spec, design, and deploy.

The Tero 20 and Tero 40 use a two-pipe hydronic system that keeps refrigerant outdoors. Heating operation extends down to -22°F ambient.

Engineered for heating. Cooling included.

If your team writes project specifications in SpecLink, Nyle is now part of the workflow.

Nyle product content is now available in RIB SpecLink. Architects, engineers, and specifiers can review Nyle product information and add Nyle equipment to project specifications within the same platform.

Find Nyle in SpecLink for your next commercial domestic hot water project.

Voltage belongs in the first project conversation.

Available voltage, phase, and electrical capacity can shape equipment selection, system configuration, auxiliary heat, controls, and installation requirements.

Bring the electrical and mechanical teams together early. It gives the design a clearer path to commissioning and avoids late changes when options are limited.

When you request a Nyle system selection, include the building’s available voltage and phase. Start with real site conditions.

Plan the power. Then plan the system.

What electrical constraint shows up too late on your projects?

📆 We’ll be at the ASPE Convention & Expo in Oklahoma City, October 8 to 14.

If you’re planning to attend, add Booth 434 to your list. Bring the design questions you’re working through. We’ll be ready to talk.

The equipment choice is only part of the job.

Before ordering a heat pump water heater, confirm the project is ready for it: site conditions, power, piping, delivery, trade coordination, and qualified support.

A unit can fit the schedule and still create problems if those details show up too late.

Design day matters. It just isn’t most days.

A DHW system still has to handle the edge case. But selection should not stop there.

Peak demand sets the boundary.

The rest of the story comes from:

// Ambient conditions
// Recirc load
// Entering water temperature
// Leaving water temperature
// Storage behavior

Size for the edge case.

Understand how the system operates outside of it.

How do you balance design-day capacity with year-round performance?

Recirculation is part of the DHW load.

That sounds obvious, but it is easy to miss in heat pump water heater design.

Peak draw tells you how much hot water the building needs at one moment.

The return loop tells you how much heat the system has to keep putting back into the water throughout the day.

That difference matters.

In older single-pass HPWH designs, swing tanks often handled the return loop because recirc was hard to send directly through the heat pump.

Multi-pass and return-to-primary designs change the conversation. In the right application, the heat pump can carry more of the full DHW load directly, recirc included.

So the sizing question is not only:

"What is the peak demand?"

It is also:

"What is the recirc load, and where should it go?"

Know that early. It affects equipment sizing, storage volume, backup heat, and whether a swing tank belongs in the design at all.

Where does recirc load show up first in your DHW design process?

Most commercial DHW sizing errors start with the same miss:
Peak day gets modeled. Peak hour gets ignored.

📆 Peak day tells you total demand.
⌚ Peak hour tells you whether the system can keep up when demand stacks up fast.

A 200-room hotel with a 6 to 9 AM shower window does not care about the 24-hour total. It cares about recovery, storage, and flow when the morning load hits.

The fix is not always bigger equipment.

It is better load math:

- Concentrated draws
- Simultaneity factors
- Recovery against the actual demand curve
- Storage strategy that matches the peak window

That is where commercial water heating specs either hold up or force changes after startup.

How does your team check peak-hour assumptions on DHW projects?
