Can a hydronic system effectively – and efficiently – provide heating, cooling, domestic hot water AND heat recovery ventilation in a residential home?  John Siegenthaler, P.E., a favorite to the webinar series, will discuss design details, challenges and lessons learned from a from a recent project profile of a modern hybrid approach utilizing an air-to-water heat pump system that checks all of the boxes during this 90-minute extended edition.

You’ll learn:
→  Back-up heating.  When is it necessary?
→  Can a single 44 watt circulator supply all space heating flow for a 2,300 square foot house?
→  Does chilled water cooling and heat recovery ventilation require separate duct systems?
→  Can panel radiators operate at supply water temperature below 100 ºF on design days?
→  Where does an “extended manifold” piping system make sense?
→  How are 3-way diverter valves applied in air-to-water heat pump systems?
→  What are the advantages of multi-zone heating combined with single-zone cooling?

Siegenthaler is a seasoned industry leader and passionate teacher, eager to share his over 40 years’ experience in the understanding and proper application of water-based engineering principles with our audience. He is the principal of Appropriate Designs and a regular contributor to industry publications.

Coffee with Caleffi technical training webinars are free and intended for contractors, designers and wholesalers.  A Certificate of Attendance is emailed to attendees following the webinar for continuing education consideration.  Want to join us?  Simply register today.

The construction industry is dynamic, fast-paced, and challenging. You’ll need to stay on your game to succeed as a business owner. Construction contracting generally involves working with clients to complete construction projects and sometimes as a sub-contractor helping to fill a smaller niche within a larger job.

As such, you may have limited control over the final scope of the project and how much money you stand to make. Without the right coverage in place, this could leave your business vulnerable. Contracting is a risky business, which is why contractors need protection.

1. Have the Right Insurance in Place

Contractors need to get the right insurance coverage in place before they start working on a project. Without insurance, your business will pay for damages and injuries during work. Make sure you have general liability insurance that covers your business’s operations.

If you are involved in building a new home, you’ll want construction insurance. Homeowners’ insurance will not cover any contractors working on your property. If you own heavy equipment, get the proper insurance for it.

You should also have workers’ compensation insurance and surety bond insurance. This coverage ensures ethical business practices and compliance with building codes. You’ll want to find an insurance company that specializes in contractor insurance.

2. Stay Current on Training and Education

You should seek out training and education opportunities that will help you to improve your business. Don’t just focus on traditional education, but also on staying up to date on the latest technology and best practices.

You can do this by joining industry trade associations. These associations will help you stay connected with other contractors and the latest information; you should also consider taking classes and attending workshops. There are many training and education opportunities available to help build your skills.

Check with your state’s licensing board to see if they offer any training programs. Training and education opportunities can help you improve your time management skills, paperwork processes, and client communication skills.

3. Run a Background Check on Potential Employees

Workers play a critical role in the success of your contracting business. You must maintain a safe work environment; it starts with hiring the best possible employees. You can screen potential employees by conducting a background check.

It will help you gauge an applicant’s character and potential risk to your business. It can also help you avoid hiring somebody who has questionable work history. Make sure to conduct thorough and accurate background checks.

Background check services are available to help you with this process. Also, talk to your insurance company about any coverage they offer for hiring employees. Some insurance companies will provide coverage against negligent hiring.

4. Maintain a Strong Payment System

Contractors rely on getting paid for their work. A strong payment system is essential to keeping cash flowing smoothly. You should have a payment system in place before you start working on a project. Some contractors prefer a payment system that is a percentage of the project’s cost.

Other contractors prefer a fixed-price system. Before you choose a payment method, you need to consider how much experience and expertise you have working on that particular type of project. You should work with your client to establish a payment plan.

You should also create a payment plan that is realistic for your business. Take into account how much work is left to be completed, any costs involved in the project, your employees’ time, and other expenses.

5. Utilize Technology to Stay Protected

Protecting your data, equipment and employees goes beyond a strong payment system. Contractors can use technology to stay protected. Make sure to have a data backup system that protects your information during a disaster.

Modern contracting involves technology, so make sure all your hardware and software are up to date. It includes computers, software, cell phones, and other devices used in your business.

It will help decrease frustration and provide a better experience for your clients. Also, using technology in construction has made it much easier for contractors to stay in contact with their clients.

Conclusion

Much has changed in the construction industry over the years. Technology, insurance, and training are just a few examples. Fortunately, all of these changes have the same underlying theme; better protection for all parties involved. As a contractor, it is important to stay protected and keep up-to-date on industry trends to ensure the longevity of your business.

Air-to-Slab Heat Pump Systems
Thursday, Nov. 17
12:00 – 1:00 p.m. CST

Technical Content Level:  Intermediate 

Air to water heat pump technology is steadily gaining traction.  When a heat pump’s coefficient of performance is maximized, energy efficiency and resiliency benefits are substantial. How can engineers, designers and installers effectively apply this emerging technology to high thermal mass floor heating applications?  Which commercial systems are good candidates for this type of design?

Hydronics expert John Siegenthaler, P.E. will detail the approaches that can best utilize this technology.

You’ll learn:
→ Do all air to water heat pump systems need buffer tanks?
→ How does the thermal mass of a floor slab compare to that of a buffer tank? → What is a simple way to control a heat pump supplying a heated floor slab? → What are the benefits of using constant circulation in “garage-type” floor heating systems?

Siegenthaler is a seasoned industry leader and passionate teacher, eager to share his over 40 years’ experience in the understanding and proper application of water-based engineering principles with our audience. He is the principal of Appropriate Designs and a regular contributor to industry publications.
