BigBarney, I've looked at solar and ikt's just out of my reach.
Besides being in an area without a lot of sunlight, the cost od storing the electric has stopped me.

Use off peak electric... Maybe even a sand battery....

PA has off peak electric to make this economical...

rberg, keeping my existing furnace ceased to be an option.
It seems that I have a cracked heat exchanger.

During this process, I learned about 2 stage furnaces.
Never heard of them before but sounds interesting.
If they work as advertised.

What fuels do you have available and their costs ???...

Then use the fuel comparison calculator on this site ...

You can make a good choice after doing a comparison...

Take into any future increases if known...

Oil and propane.
I spent 40 years in the home heating oil business.
Propane only has approx. 2/3 the BTUs per gallon as oil.
I do know the economics but appreciate your suggestions, Big Barney.

I will be using propane for primary fuel.
Not oil nor electricity.
If I could economically store solar electric, I would consider that.

But a heat pump is almost double the initial cost to a high efficiency propane furnace.
And a little more than I'm able to stretch right now.

If I understand how a dual stage gas furnace works, a 96% dual stage furnace will be pretty efficient much of the time.

Very interesting, to me it seems like a 'low budget' practical application of this would be a sandtank in the basement, with a copper or pex grid of piping, kind of like a humungous storage tank/indirect tank. Your boiler could run once a day (or once every few days in the summer) to heat up the mass and then the piping grid could extract the heat as needed. I feel it's a LOT easier to insulate a sandbox than a water tank....plywood, blue board, and spray foam couldn't add up to that much. Install check valves to prevent heat loss...

I do wonder how high the sand can be heated, that would determine energy density. Also I wonder where the most cost is coming from, is it really refined special sand or is it other things.

I have one of these for forced air heating... Especially if you have ducts...

https://www.steffes.com/wp-content/uploads/2016/09/CP-14.pdf

It works just like a futnace only it stores the heat in the bricks...

Buy 100% of your heat at off peak prices...Usually 50% off or more...

Compare the price of your other fuels per kwhr...

I have the 3120 model with the highest option...

What do one of these cost to buy?
Did you install it yourself?

Since I only, cursorily, looked, how many circuits are needed?

Is there any way I can supplement the heating of the bricks with wood/coal, for example?
Thanks for sharing.

Maybe the room units would be better...

How many rooms and sqft do you have?

The 2100 models are a possible solution...Without a 200amp service...

Do you have a 200 amp service? I don't but have 3 100amp sevices...

Since these charge at night even the 100 amp service can be used...

I was able to buy these used for $150 and less...

They are easy to install just pile in the bricks and hook up the electric..

No.
I don't think so.

I do not have 200 amp service.
Thanks for the suggestion.

How many BTUs does a room unit store?
What is the regular price and the off-peak price of electricity where you live?

For me, I'm not interested in this.
It's nice to know because I was unaware of such a thing.

They store from 46,000 to 136,000 BTUs... Depending on size....13.5 to 40Kwhr...

https://steffes.com/wp-content/uploads/2021/03/21 ... -Sheet.pdf

Off peak electric is approx 50% off the rate... In NY ... In PA it is similar...

Electric rate in winter are usually the least expensive...

So this rate for off peak is 66% off ...Peak=.13812 Off Peak=.04562...

Plus taxes and fees...Some are credits and some are debits...

Larry How much is fuel oil and propane in your area?

The NYSerda Price 15Apr2024 fuel oil is $4.14 and Propane is $3.30 gallon...

Kerosine is $4.90 gallon so I inserted them in the fuel calculator on this site...

I also changed the efficiency column to 100% for the geothermal which is now

off peak storage heat... To make it comparable...
