Why facilities teams say yes

An energy modulation with a return you can calculate up front.

No guessing or leap of faith. We quote installation based on your equipment and savings from your energy expenses. You see the ROI before you commit.

01

20% Less Energy

The efficiency technology improves heat transfer, so your boilers burn less fuel for the same output.

02

No Downtime

Applied to existing pipework without shutdown or process interruption.

03

2-Year Payback

Installation that offsets itself in about two years and retains profits for the warranty term.

04

10-Year Warranty

A fixed annual rate covers maintenance, support and OH4's 10-year warranty.

How we price it

No guessing. We forecast your savings from your equipment and energy expenses.

Integrated Savings: Installation is priced from your boilers and pipework; savings are calculated from your last 12 months of energy expenses. You see the fully projected ROI before you commit.

1

Provide The Evidence

We provide proven technology, testimonials, and results from comparable facilities in your industry.

2

Establish Your Installation Layout

From your boiler count, boiler size and pipe diameter; we start by providing a no-cost site assessment.

3

Estimate Your Savings

From your last 12 months of energy expenses, applying a ~20% average saving; your ROI is built on your actual numbers.

4

Install & Support

A one-time install and a fixed annual rate inclusive of maintenance, support and OH4's 10-year warranty.

How it works

A proven thermal efficiency technology. Installed with zero downtime.

Our OH4 technology system improves heat transfer across your heating and hot-water circuit, so the boiler or heat source does less work to hold the same setpoint. We reduce your heat energy costs by around 20%.

ON THE MECHANISM

The precise formulation is proprietary — and we're transparent about that. What matters is the outcome: a measurable drop in the energy your heating system burns, proven across years of installs and backed by a 10-year warranty. Engineers can request a technical deep-dive under NDA.

Proven across real installs

Where it fits best

High Heat. High Hot Water. Any Industry.

Food and beverage manufacturing facility

Food & Beverage Manufacturing

Bakeries, breweries and other manufacturing processors run large-scale steam and hot-water systems. OH4 technology is the clearest, cleanest and most efficient path to irrefutable savings.

Beachhead vertical
Commercial and hospitality laundry operation

Commercial & Hospitality Laundry

Due to persistent high hot-water demand and hard-water scale, laundry facilities offer one of the clearest opportunities for measurable savings and performance improvements.

High hot-water intensity
Multi-site facilities and central plant

Multi-Site Facilities

Hotels, hospitals and university central service buildings; OH4 technology can be applied and scaled across sectors.

A one-time installation quoted from your boiler count, boiler size and pipe diameter plus a fixed annual rate that includes maintenance, support and OH4's 10-year warranty.
From your last 12 months of energy expenses, applying a ~20% average saving. Your ROI is built on your actual numbers — you see the verifiable savings before you commit.
An average of two years for a typical install. Savings multiply for the life of OH4's 10-year warranty.
Nope. OH4 is applied directly to the outside of your existing pipework without disruption of any systems. Zero system shutdown and zero process interruption.
OH4 improves heat transfer across your heating and hot-water system, so the heat source requires less energy for the same output. The precise formulation is proprietary; the outcome is a measurable drop in energy use, across multitudes of installs. Engineers can request a technical deep-dive under NDA.
Commercial and industrial sites with significant heating or hot-water expenditures — e.g. Food & beverage manufacturing, hospitality, commercial laundry, healthcare and campus central service locations. Closed-loop systems are an especially clean fit, but they are not a requirement.
