I suppose it would be nice to have a heating/cooling system in the house. Some examples:

Primary Heating System
Secondary Heating System
Tertiary Heating System

Examples would be:
Gas forced air
Solar hot water
Wood stove

You'd do the same with cooling systems as well.


Do you guys think this would be useful? Perhaps just leaving it as an text field would be fine instead of a drop down? Drop downs are better for searches, but they don't always have everything in them.

More feedback. :)

Added Tim's suggestions. Gimme more, looks a little bare as it is.

OK, so what exactly am I seeing?

http://ecorenovator.org/forum/attach...1&d=1290002818

SVOboy used 8 (kWh? therms?) on June 17 2010?
And Daox used 8 on January 1 2010, then 0 until June 1 2010, after that 8 between June 1 and October 1 2010? Then it goes back to April 1 2010?

How is this going to be displayed? Will it be a bar graph like in EM's fuel log, and will it be accessable from a member's profile and/or a link under his avatar? Or will everyone's data be grouped together in a dedicated section?

I want to help out so I'll my data in as soon as I find and convert it. How often should I enter data? Every month, every day, 2-4 times a year? Will everyone's data get converted to something that's easily comparable, for example kWh per day? That way when I look at a list of numbers I'm not comparing Daox's total for 2 months with my total for 2 weeks.

Daox 11-17-10 08:38 AM

Its all just test data so far. Obviously, the reporting functionality isn't fully developed yet.

You shouldn't have to do any conversions to input energy usage, we should be able to let you input whatever units you have. After that the site will convert them to the universal comparison unit we decide on which right now is kWh.

You can enter data as often as you like. I'll be doing it monthly. Some people only buy wood once a year, they can enter it yearly. It will all average out over time.

For the heating systems you need to add more options

My house is air source heatpump, electric furnace and woodstove.

Also for the prices on the next page what is that meant to be? electricity price is this per kwh or for the total bill?

Daox 11-17-10 09:40 AM

Yes, more heating options need to be added. We'll also need cooling systems. I'll keep an official list here:

heating systems
gas forced air
wood stove
air source heat pump
electric
oil boiler
gas boiler
ground source heat pump
solar hot water
solar hot air


cooling systems
whole house fan
air source heat pump
ground source heat pump
evaporative cooler


water heating systems
On-demand gas
On-demand electric
Tank gas
Tank electric
Tank solar
Tank air source heat pump
Tank ground source heat pump
Tank wood stove
Tank oil



What else am I missing?

Do we want to specify what water heating systems we have? Its a fairly large portion of energy use. I'd think so. EDIT: Added them per Piwoslaw's list.

Prices will be in price/unit.

SVOboy 11-17-10 09:50 AM

Thanks for keeping the list Tim.

Updates: now allows correlation of home to entries. Basically essential. It's getting late here in korea so I'll get some more work done tomorrow morning. On the chopping block for then is updating the fields you guys have mentioned, as well as updating the main page to something that actually means something. It may be boring at first (just a table of values), but at least it'll meaningfully cough up information.

Near future planned additions:
- editing function
- picture uploading capability
- graphs
- conversion inputs for varying means of measuring

Keep the ideas coming, I appreciate the help.

Yes, we do.
List:
  • On-demand gas,
  • On-demand electric,
  • Tank gas,
  • Tank electric,
  • Tank solar,
  • Tank air source heat pump,
  • Tank ground source heat pump,
  • Tank wood stove,
  • Tank cosmic radiation (just keeping you on your toes:p)
  • Any combination of the above.
We have two hot water heaters, one on each floor (there used to be two families in our house), which will get replaced sooner or later by a hot water tank, electric with solar assist (or the other way around, hopefully). Maybe with a small heat pump to capture waste heat from ventilation. So I'd like to have a few options for hot water sources in the future.

Daox 11-17-10 11:01 AM

Yeah, we'll have to have primary/secondary/tertiary water heating systems as well.

For cooling and heating, I think Mini-split Inverter ASHP should have it's own category.
It after all Ductless is cheaper to run, and a very different breed of animal when compared to regular (1970s?) heat pumps.


For water heating systems, Tank Oil should be on the list.
PV might be added too.. :)
Or my Hybrid hot-water system, using both oil and PV.. :o

~~~
Actually, I might even do some Hybrid Oil+PV house heating this winter.
We have our oil burner on a 1/2 hour timer (early AM run), but if there
is good solar, the PV can keep the storage pretty warm all day.
So at night, I can open the check-valve / 'free-flow' and allow semi-hot
water to convection feed up into the house for a couple of hours..
Eureka! PV+Oil heating.. A few BTU anyways.. :D
Makes no sense to let heat dissipate into basement floor etc,
overnight, when it can assist the Sanyo (keeping us warm while watching TV). :)
