  Heat Pump Sizes and Conversion to Btus
Posted by: Jay412 - 05-06-2016, 02:33 PM - Forum: Renewable and High Efficiency Heat - No Replies

Hello, 

I am trying to calculate how much Btus you can generate with a given Heat Pump size, which is usually measured in tons. What is the information that I need to do this conversion? How much Btus can you expect a 4 ton heat pump to generate? I understand that there are a lot of variables involved in this calculation, and I would really appreciate it if you could provide any rough estimates. Thanks.

  Three-way herbicide treatments
Posted by: beckyhennessy - 05-05-2016, 06:00 PM - Forum: Vegetables - Replies (1)

Hi, don't know that this is the exact place for this question. We're a new housing development just outside of Ithaca -- on East Hill. We're looking at weed treatment options for our common lawn area, which consists of two standard street-length strips of grass between the sidewalk and the curb. It's currently riddled with dandelions and other weeds.

We want to pursue environmentally safe options. As such, does anyone know about "three-way" herbicide treatment? Should we be concerned that it might adversely affect groundwater? If so, any suggestions for an effective alternative?

By the way, the vendor we're considering proposes the following application schedule (see below).

I do apologize if I'm posting this in the wrong place. Thanks much!

Best, Becky Hennessy

----------------------------------------

Application 1: April 1 – May 15th: Stonewall 0.43% 13-0- 0 30% Ployplus fertilizer and pre-

emergent crabgrass control. Spot broadleaf control with Three Way herbicide.

Application 2: June 15 – July 30: Merit 0.2% 18-0- 0 40% Polyplus fertilizer subsurface insect

control and spot broadleaf control with Three Way herbicide.

Application 3: August 15 – September 30: Balanced slow release fertilizer 18-0- 3 40% Polyplus

2FE and spot broadleaf control with Three Way herbicide.

Application 4: October 10 – November 30: Fall fertilizer 30-0- 0 25% Polyplus.

  Inviting all Electric Vehicle (EV) questions...
Posted by: Art Weaver - 05-01-2016, 08:24 PM - Forum: Electric Vehicles - Replies (4)

Hi everyone ~ I'm a scientist. I don't claim to be an "expert" in EVs, but I am quite knowledgeable about renewable energy and battery storage. I lease a 2013 Nissan LEAF (3 years, Jun 2013 to Jun 2017) which now has over 23,000 miles on it - with zero maintenance so far - and zero emissions - and very little "range anxiety". All of you who are still driving ICE (internal combustion engine) vehicles are... how do I say this nicely?... part of the problem (no, that's not nice)... conservative (no, that's not nice either)... impoverished (well, maybe)... ignorant (not nice, but forgivable if you haven't graduated to indy media).

So, now that I've probably insulted you, ask me an EV question like:
Q: Why don't I see more EVs around?
A: Because, by and large, auto dealers don't want to (or know how to) sell them. If there's interest, I'll elaborate...

Q: What's Consumer Reports' highest rated car ever?
A: An EV - the Tesla Model S (two years in a row)

Q: Are EVs expensive?
A: Depends on your perspective. Compared to what? A typical SUV? A Mini? What's the value of near-zero maintenance and near-zero fuel cost? (rhetorical)

  high potassium and phosphorus levels in soil
Posted by: margotbrinn - 03-22-2016, 10:31 PM - Forum: Vegetables - Replies (3)

Hi.  My soil has tested extremely high for both P & K.  Did I add too much manure?  And if that's my problem, how can I add a locally sourced source of nitrogen without raising the other two levels?

Thank you.

  Home Heating/Cooling with Heat Pump Units and Systems
Posted by: HeatSmartTompkins - 03-01-2016, 04:29 AM - Forum: Renewable and High Efficiency Heat - Replies (1)

Greetings-- my name is Matt Johnston. I am the Director of HeatSmart Tompkins, a county-wide program of Solar Tompkins. I am thrilled to be assisting Get Your GreenBack Tompkins and contributing to this forum on renewable and high efficiency heating.

I am knowledgeable about heat pump systems--ducted and ductless air-source units, air-source hot water heaters, ground-source geothermal systems--that can be utilized for home heating and cooling. Heat pumps run on electricity and are highly efficient, making them an attractive fossil fuel-free option to heating with propane, fuel oil or natural gas, each of which generate significant greenhouse gas emissions that contribute to regional and global climate change. Further, these traditional heating types can be expensive, and with 75% of home energy use going toward heating and hot water, heat pumps are an increasingly attractive alternative! In combination with better building insulation and air sealing, heat pump systems can comfortably meet 100% of your home's heating needs here in Tompkins County.

Click here, here, and here for more information about heat pump technology, and feel free to pose questions in this forum for me and other moderators to answer. Thanks, and we look forward to hearing from you!
