SB 18 is back in committee but the Polypro vs PVC debate lives on

As many of you already know, District 14 State Senator Sharon Carson, (R-Londonderry), introduced on behalf of an anonymous constituent, legislation in the 2015 session that would ban using Polyvinyl Chloride (PVC) piping for flue material when venting combustion gases. This would include High Efficiency Gas furnaces.

As it stands, SB 18 has already been through its public hearing and has been sent back to committee for further study and possible amendment. It will most likely be voted on in the beginning of the 2016 Legislative session.

In a perfect world, meaning the equipment was 100% efficient, the flue gas temperature for a gas furnace would be the same as the thermostat set point and on a water heater or wall hung boiler it would be the same as the water temperature set point. In reality, 100% efficiency isn’t possible, so the flue temperature will always exceed the thermostat set point temperature.

"The New Proposed Mechanical License"

How many of you have heard about the new proposal for a Mechanical Licensing Law being proposed by a “small group of industry members” to combine licensing for plumbers, gas fitters and oil burner techs (yes another license), all of who are under the regulative authority of the Department of Safety into one mechanical licensing board or entity?
According to the NHPMC Pipeline Newsletter this proposal came about because of two bills introduced in the NH legislature this session, HB 517 calling for the repeal of the gas fitters law and HB 394 which would have required licensing for oil burner technicians. Both of these bills are dead for this session but will be back next year.

 I thought they were supposed to be for a two year term but if you read the procedures for license renewal you will see this is not so. See 3.02 below.
