Hello there

In my house there currently is an electric heater, but it's not enough. So my mother wants to install a gas heating system so we can heat all the rooms instead of just one. But it seems like a backwards move in my eyes. Definetely with the new solar "boom". I would suggest to put more electric heaters (better ones) across the house and invest in solar panels. So we don't have to rely on gas or the grid.

So if somebody could give some answer to these questions?:

1. What are the most efficient/durable/cheap solar panels?And where to buy?
2. What is a good storage system for the energy? Powerwall or connect back to the net or deep cycle batteries
3. What are the highest efficient electric heaters?

For the best return on your money usually insulation is the best bet rather than installing a new bigger heating system but it depends on your house and the current set up .
As for solar check out what the electric company has to offer as a price for your generated surplus to work out if it would be better to have more cells rather than a battery system ,

Depending on your solar exposure you could consider solar thermal. Directly heating the house air with the sun instead of converting sunlight to electricity, storing it, and then converting it back into heat. Here's a site I like for solar projects: Build it Solar If you are DIY or handy these systems can be very affordable. They may limit your heat to the southern rooms but that may be enough to get some circulation going.

Insulation first and foremost save what you got rather than try to heat a house with more energy. I'm unaware of any recommendations in terms of electric heating and solar energy fact is most homes need heat at night and majority of electric heating systems utilise a huge amount of energy although I get the selling back to the grid to use up any credit at a later date.

Some questions I maybe ask why is your house cold? Certain rooms colder than others? Are there drafts between rooms? Drafts coming from outside? If you cannot insulate from the outside what about from the inside? What about just changing your heating habits, what is the actual temperature of each room? Maybe it isn't cold? Are there unused flues in any rooms? Remember wood burners need oxygen and so too your lungs to survive, thus, drafts are essential part of a house with a wood burner. Really require to heat an entire house, every room & hall way? Does your door(s) open straight onto the outside world allowing the heat -entire house- out when open, could I build a double door to keep the heat inside while I open an exterior door? A few questions to ponder I'm sure are more.

Insulation/building envelope efficiency is the main target, unless you have already been there.

Chosing the best approach will depend on the climate in which you live and if you plan on staying on grid power as storage and backup for renewable energy.

Altestore.com for good prices, selection and education for DIY.

We are finding that adoption of air source reverse cycle chillers are great for solar electric heating and cooling (radiant hydronics, low temp), here in the north, most of the year. A back up is required for extreme low outdoor temps.

You cannot go wrong with most pv modules, if you are not concerned about a warranty. They represent the highest reliability and service life of all consumer goods short of a stone door stop, or roofing steel.

If you live in an area with mild winters, a pv system of modest size may grid tie, net zero your heating bill over a year, even with resistance heaters.

Check out pv direct-drive, reverse cycle chillers. They can supply heat for dhw and space heat and transfer to grid power when solar availability is short. Cool tool.

The power wall is a cheap carrot on a stick at this point, or shell gamery. Elon is too busy planning on mining asteroids, moons, and terraforming mars with nukes. They are not producing a consumer automobile, nor will they produce a workable/affordable storage solution for those wanting to optimize energy usage or stabilize/pre pay permanently, cost.

Its called "Industrial Engineering"

"Industrial engineersĀ are the bridge between management goals and operational performance. They are expected to exert leadership in workplace education as well as analysis, design and implementation of systems and plans for operating those systems that bring value to the organization."

We sized a medium commercial battery system, pretending inverters were available, and found we needed 54 7kw power walls!! I have no interest in wiring that mess. We found the same storage in 8 modules of aquion batteries, available to purchase and operates at common dc voltages.

Please stop waiting on tesla to provide unobtainium, decades are passing by....

The guys at evtv have some great tech. They have some insight on us controlling our transport and home power. Great reading and vids there.

I agree on the comment about the powerwall. What's good for cars might not work so well for energy storage at home, & that will bear out with time. I've looked at multiple home storage technologies & settled on the Aquion. I'll be doing videos & articles explaining some of these issues about charge / discharge cycles on Aquion's blog & others each month besides my own YT channel at http://bransonoffgrid.com . Here is my first Aquion article just posted 11/23/2016 - http://tinyurl.com/zdt3auw & the first system I designed using the 30kwh module -
