I missed something!
I did not see his Heat Load anywhere, nor did I see his utilities rate..

If his electric rate is high and his Heat loss is higher than 45,000, then I can agree, till then, I...

I concur..

I vote for one system.
If you know how to design, then it should not be a problem with only one system, especially when you mentioned a dual-fuel set up... you have your backup already built-in!...

Cooling load of course. It doesn't matter if you're in a heat dominated area!! How would anyone size an ASHP two-stage in the Northern Climates?? The same way!!! I've seen my competitor's do it the...

Having a pool indoor and extracting its heat and heating the pool (pool boiler) to maintain its temp just to increase its efficiency (Geo unit); is it cost effective?

Anyone!!

The same way you take alcohol away from folks....

Doing the right thing is the smart move no matter what men may say or do.

May you be smart to know the difference..

Godspeed.

It tells more than this.

1. Heatloss tells me what capacity I need for heating...
2. Heatloss tells me what amount of air flow I need...
3. Heatgain tells me what amount of airflow I need...
4....

I disagree...
How would you know the proper airflow if no Heat-Calc is done? Answer that!!
How would you know if the AC is even the right size? Really guys...

You do a disservice every time a...

I actually need/want to be able to go below the 0 degree temp line. Not all my intersect lines are above the 0 degree section (Economical BP).

Welling, you should have it by now...

I've notice you did get the file.

What would be nice is if I could get in the program (unlock it) and did some modifications to it... anyone!

I've seen your email in your profiles, did you get it?

Really Cool!

I've yet to install one.
Perhaps 2013.

lan,

Here's a formula for figuring out the tank size.336421

Sure, you can use water heater tanks, but it would require you to pull out the elements and put nipples in them.
The 3/4" on top can...

Question:

What is the lowest capacity that the Mod/Con produces verses your lowest heatload would be? Do they match?
If your boiler lowest output is higher than any zone's needed capacity; you...
