Frequently Asked Questions

Q: How does the Ultramizer compare to current condensing systems related to cost, payback & reliability?

A: The simple return on investment for most CBW customers is from under one year to about five years – most wanting payback on the installed cost within two-three years or sooner.  CBW products are capital intensive, but still with a reasonable one-three year payback on most, and the expected life of our equipment is 20 years or more with proper maintenance. It seems likely that many customers will come seeking our products if corporate sustainability campaigns require them to continue to find more energy saving measures year after year.

Cost: The Ultramizer will cost 20-50% more than traditional condensing systems. However, an additional

3 – 5% in fuel savings can be achieved which can represent a substantial amount of money over the
life of the system.

Example: 300 HP system operating at 95% vs. 90% efficiency
Assumption: $6.50 / hour fuel cost savings

(does not include water savings which would provide additional $$)

Results:  $50,000 in savings over 1 year or $500,000 in savings over 10 years
Unit payback:  1 – 1 ½ years depending on market cost of fuel
Installed payback:  2 – 3 years
Reliability: Reliability statistics are still being determined. However, there have been no process-related
failures of the ceramic tubes to date. The first 2 stages of heat recover are traditional CBW
economizers with 1,000s of successful installations and backed by over 30 years of experience. To
date, the TMC 3rd stage has over 20,000 hours of testing with no process-related failures.

Q: How much does the Ultramizer cost?

Product Price
300 HP Ultramizer Base Unit $100,000
300 HP Stand Alone Ultramizer System $165,000


Q: What is the ease of maintenance related to the Ultramizer? Will it have similar maintenance features to other CBW products?

A: The ceramic tube bundles in the Ultramizer are removable and easily replaceable. CBW used the same thought process for the Ultramizer design to ensure ease of maintenance.

Q: How much water does the Ultramizer recover?

A: It’s estimated that up to 20% of the moisture in the flue gas stream will be recovered.

Q: What’s the condition of the recovered water?

A: The water that the Ultramizer recovers can be immediately used in the boiler system without treatment. It should be noted that the recovered water from some competing systems require treatment prior to being used again in the boiler system.

Q: What happens when I switch to another fuel, either because natural gas isn’t available or the price is too high?

A: The first stage economizer will work fine with fuels other than natural gas. At this time though, the Ultramizer has only been tested with natural gas and as such can only be used with natural gas. A bypass system has been incorporated so that customers can easily switch between different fuels. CBW is in the process of testing the Ultramizer with fuels other than natural gas. To date, no equipment damage has been seen during testing when alternate fuels were used.

Q: How quickly will I receive Ultramizer spare parts?

A: CBW typically maintains a stock of fin tubing and ceramic tube bundles. In-stock items can be shipped immediately. Replacement time will depend on whether or not the spare parts are in-stock. Items that must be ordered typically have a 3 week lead time.

Q: What will the shipping costs be?

A: Ultramizer shipments do not require over-sized loads or special permitting.

Q: What are the space requirements for the Ultramizer?

A: CBW provides multiple installation scenarios to fit your boiler room set up. While the Ultramizer requires 50% more space than a condensing economizer system, it should take less space than direct contact water heaters.

Q: What is the weight of the Ultramizer?

A: The weight will be similar to condensing economizer units.

Q: What structural support is required for the Ultramizer?

A: CBW has developed multiple installation scenarios to suite most boiler room set ups. A structural support (not provided by CBW) will be required around the boiler to hold the Ultramizer. Floor stands and skid units are available from CBW (a detailed site plan will be required).

Q: What installation support will CBW provide?

A: The majority of the installation support will be provided by CBW’s local representatives, although CBW factory assistance will be available upon request.

CBW plans to provide factory service technicians for the first 10 Ultramizer installations.

Q: What is the major drawback in selling heat recovery equipment.

A: Education of our customers, so they can make good decisions for the long term, is the most important aspect of our sales and marketing efforts. We have seen this landscape change in the last ten years. Now consumers are being constantly reminded to buy the most energy efficient products at home and work, and how much money they loose if they do not.  CBW does not have to convince them that this course of action is necessary, we only have to educate them to the benefits of our equipment over our competitors, and there are many.

Q: What problems will the equipment cause my existing equipment?

A: CBW equipment is designed to first eliminate the possibility of negative affects on any other surrounding equipment. Secondarily it is designed to optimize the heat and water recovery for the customer’s specific operating conditions.

Q: How much more maintenance will be required?

A: CBW equipment includes components that are always found in boiler rooms (heat exchangers, fans, pumps, controls), and therefore we minimize any risk of maintenance issues. The equipment is designed for the industrial boiler room, and does not require more maintenance than the other pieces in that room. Bi-annual inspections are a good practice for every piece in the boiler room, our equipment included. Look for signs of water leaks, corrosion, or fouling (ash) on the combustion side, and with thermometers and pressure gauges any drop in performance on the water side can be minimized before they cause any operational problems.

Q: I have heard that condensing the flue gas from combustion systems causes corrosive acid that will damage my equipment?

A: This is an old concern from the days of heavier fuels, limited material availability, and lack of knowledge and experience with cooling flue gasses into the condensing temperature range.  Within the last five-seven years condensing of moisture in the flue gas is commonplace for natural gas burning systems for residential, commercial and industrial systems across the board. CBW can provide the right combination of heat recovery and long life for each customers specific operating conditions.

Q:You have fans and pumps in your system that cause some parasitic energy losses that should be deducted from the gross heat and water recovery gains?

A: Yes CBW will document the energy used by the fans and pumps in our systems.  We expect it to be a minimal loss compared to the overall efficiency gain the customer will receive. Note: rarely do boiler manufacturers consider the electrical operating expense when making efficiency claims, but CBW is working on these issues to fully satisfy our customer base.
