  1. On Demand Water Heater An Improvement on the Existing Electric Heater

  2. Introduction • Our team • Antonio DiCianni • Christopher Kaskoun • Vincent Tancredi • Daniel Taurone • Dung Truong • Our advisor • Dr. Giuseppe Palmese • Problem Introduction

  3. Problem Background • Existing water heating methods • Traditional Tank Heater • Tankless WaterHeater • Gas • Electric • Resistance Heating

  4. Traditional Water Tank Heaters Foam Insulation http://www.mechanotherm.com/images/hot_water_heater2.jpg http://www.remodelguide.com/improve/plumbing/waterheaters/waterheaters_intro.gif

  5. Electric-Resistance Instantaneous Water Heater FLOW OUT FLOW IN

  7. Electric-Resistance Tankless Water Heater • An electric-resistance water heater has electric heating elements submerged in its storage tank. • Expensive • Electricity costs more per unit of delivered heat than gas. • require a large power supply. http://hes.lbl.gov/hes/makingithappen/no_regrets/waterheaterelectric.html

  8. Criteria for Success • Size Constraints • Electrical Consumption • Viability • Installation • Lifespan • Maintenance • Cost • Safety

  9. Possible Solutions: More Insulated Pipes Currently • For tanks and exposed pipes • Inefficient Modified solution • Insulate ALL pipes • Materials • Polyethylene, Neoprene Foam, Fiberglass Wrap, Polyurethane • Inexpensive • Self Installation

  10. Typical Plumbing Schematic for a Single Family Dwelling Primary Source of Shower Temp Fluctuations KEY Cold Water Flow Hot Water Flow Appliances Heat Lose Ground Water Inlet Tank Water Heater http://www.grundfos.com/web/HomeUs.nsf/GrafikOpslag/HWR_System/$File/house2.jpg

  11. Possible Solutions: Modified Mixer Valve Currently • Manually set to mix hot and cold water • Fluctuating temperature Modified Solution • New mixer to automatically detect fluctuation and adjust to keep proportion • Changes: • Laser detection • Software system • Monitor • Adjust http://www.plumbingpages.com

  12. Possible Solutions: Pros and Cons Thus Far

  13. Possible Solutions: To the Source Analyzing point of energy usage • On all the time • Where most energy is lost Mission: Design New Heating system for the shower • Pros • Will not be on all the time • Heat at the point of usage: no wasted water • Problem: Heat and Power source

  14. Possible Solutions: Types of Hot Water Tanks Top Choice: Electric

  15. Possible Solution: On Demand Water Heater Currently • Electric showers and tank-less water heater • Inefficient, slow, power usage Solution • Heating in or through pipes by electric power • Possible methods • Block (outside) • Coil (outside) • Electric Cartridge (Inside) http://www.inductionheating.com/images/ph_front_coil.jpg

  16. The Ideal Solution • On Demand Water Heater • Design • Improved heating mechanism • Fin System • Benefits • Easy Installation • Maintenance • Safety Device • Energy Conservation • Cost Efficiency Implication of fin system stemming off of the cartridge heater http://www.omega.com/Heaters/images/CIR_14_l.jpg

  17. The Ideal Solution Pre-manufactured Cartridge with Fin System Easy Installation into Piping

  18. The Ideal Solution

  19. Schematic of our Design

  20. Research Conducted P = (m/t)C∆T

  21. Amperage

  22. Recommendations for Future Work • Digital Interface • Calculations to determine effective materials • Optimal Fin design • Most Effective Cartridge Heater http://www.ubergizmo.com/photos/2006/3/kohler-dtv.jpg

  23. Conclusions & Discussion • Flaws of previously existing designs • The ideal design • Meets economic, safety, and comfort standards • Primary design goal • Decrease energy lose • Increase annual savings

  24. Questions?
