Only one slide is available:  JOINT OBJECTIVES WITH EmpowerNJ
1.      Establish annual NJ targets for heat pump installations, from now to 2030 and beyond
2.      Require increasingly stringent building codes to make new and old buildings energy efficient.
3.      Start, NOW, the NJ transition to heatpumps
4.      Maximize customer education, marketing and incentives for energy efficiency audits and improvements.
(Hap Haven's slides await NJ BPU approval)
Following are Hap Haven's comments and replies to your questions:
Hello and thanks for a great webinar last night.  I’m very sorry for running long especially because it bumped the heat pump owners to another date.  I think the groups especially liked Scott’s talk – real world experience rules!  I’ve attached the Q and A below.  I hope it works for you. Have a great weekend,

Q and A – many questions were answered during the event
From Brian Morgan to Everyone 07:41 PM
Are Heat pump water heaters better then tankless water heaters?  If so, why
It’s an apples and oranges comparison.  Both are great technologies and solve different problems.  I generally don’t see electric instantaneous water heaters except for powder rooms where they are used for very small hot water needs.
From Caroline Hancock to Everyone 07:43 PM
Yay for an induction cooktop, I need that extra counter space!
Also, we are learning that gas ranges constantly leak gas, bad for people in the space and bad for the climate.
Absolutely correct.  Gas ranges and ovens are unvented heating appliances.  They regularly spill combustion products like CO, nitrogen oxides and fine particulate materials into the house.  All these affect the health of the occupants.
From Charles Nunzio to Everyone 07:43 PM
Townhouse restrictions? Buried power cables may limit available power to each unit?
Yes, most townhomes and condo developments have restrictions on utilities.  Obviously, you need to check with your Homeowners Association before signing any HVAC or solar contracts.
From Peter Massardo to Everyone 07:44 PM
Are these heat-pump appliances sold in regular retail locations? Are there different manufacturers and how to evaluate those?
I haven’t seen any cold-climate heat pumps in retail stores, but they are available online and obviously through the HVAC contractor you hire.  Make certain that your contractor has experience installing these.  Double check with the NEEP website to see if the heat pump you’re buying is listed.
From Gerald Dalzell to Everyone 07:44 PM
I have read that induction ranges require specific cookware.  If your pots don't respond to a magnet, they won't work with induction.  True?
Yes, induction cook tops need high iron content cookware.  Obviously, any pot or pan made from cast iron will work.  In addition, look for cookware to be stamped “induction” on the bottom indicating it will work.
From Mark Hackler to Everyone 07:47 PM
Who sells cold climate heat pumps and who does energy audits?
There are roughly 9,000 HVAC contractors in the state of New Jersey.  I would search for the highest rated contractors near you then go to their websites to see if they feature heat pump installations. Get testimonials and find out which brands they install.  Check a few models against the NEEP data base.  About energy audits - check with your local utilities for a list of their Home Performance Contractors, then cross check them with the Building Performance Institute list of auditors.  You can also do that in reverse – start with BPI and cross check with the utility.
From Michael Winka to Everyone 07:48 PM
Hap - how do you address the decrease in temperature in the winter if one puts their electric heat pump water heater in the basement? should I un- insulate the hot water pipes and baseboard hydronic pipes in the basement ?
Most heat pump water heaters need 100 square feet of space to draw heat from.  This is usually the basement.  It’s recommended that the unit’s exhaust air be vented outside.  My preference is to vent outdoors in the winter and indoors in the summer.
From Jennifer Nielsen to Everyone 07:48 PM
For some reason, when we installed our heat pump for heat/AC, we were told we could not get a heat pump water heater. Any explanations?
I really don’t know; you’d have to ask the contractor for specifics.  It could be a number of things like the height of your basement, problems with venting, supply chain issues, no room in your electrical panel for a 240v line or they just didn’t want to do the work.
From to Everyone 07:49 PM
Where can you find certified energy auditors for guidance, and do you have advice re insulating underneath a residential flat roof?
I’ve answered the auditor question earlier in the Q and A.  As for your flat roof, it depends on how flat, if it’s vented or not, and how much attic space does it have? (most “flat roofs” have 36” attics up front tapering down to 10” attics in the rear)  Second tier questions include are you doing any renovation work, do you need a new roof and can you insulate on top of the roof?
From Caroline Hancock to Everyone 07:49 PM
A colleague in my climate change organization told us that her heat pump system was only good down to 27 degrees; she kept her gas-fired furnace as backup. So, you are saying that currently, there are heat pumps that will still work at lower temperatures?
Yes, these heat pumps are known as cold-climate heat pumps.  A huge number of HVAC contractors don’t even know they exist and are still selling lower efficiency units. That’s not a real problem if the gas heater is a high efficiency unit >95%.  Cold-climate heat pumps are the electric solution to phasing-out combustion heaters.
From Enis Bengul to Everyone 07:50 PM
Where are the requirements for siding of a net zero house?
The are no requirements for siding in net zero homes.  It’s the insulation and air tightness of the entire wall assembly that counts.
From Mark Hackler to Everyone 08:03 PM
How do you compare cold climate heat pump efficiency to that of a gas furnace?  I heard of a Daikin heat pump with a gas furnace back-up.  Why would I do that if the heat pump is comparably efficient at 0F?
Heating and cooling manufacturers try to provide customers with a wide range of appliances to solve every need.  There will be customers who insist on having gas stoves and ovens, as well as heaters.  The heat pump – gas hybrid heaters satisfy this niche market.
From Michelle Vosper to Everyone 08:06 PM
Is there any technology which recycles storm water from the roof and gutters for any relevant use?
Rainwater can be reused for the garden and even for potable water.  Some municipalities have regulations controlling this, but the science and mechanics is rather straightforward.  Visit @greenhomeguru and see some of the work I’ve done in my yard.
From Michael Winka to Everyone 08:11 PM
Scott or Hap - how do you see the energy building codes being upgraded to at a minimum require the installation of heat pump hybrid systems in new construction.  Should electric resistance baseboard heating be phased out with cold weather HP in retrofits/remodeling and new ?
Electric baseboard heating comes in a number of shapes and sizes.  Coupled with a fan, it’s a particularly good solution for spot heating in older homes.  Of course, I can’t recommend it to heat a house.  I think the market will phase out this type of heating in the near future.
From Jennifer Nielsen to Everyone 08:26 PM
Our system is Fujitsu any thoughts about that?
Fujitsu is a major player in this market.  I see 135 models listed on the NEEP website.
From Alexander Brown to Everyone 08:26 PM
If you are looking at Air-2-Water DIY situation, try Chiltrix
I couldn’t agree more, and they are currently creating a new system that uses R32 refrigerant.
