Furnace Forced Heat Systems and Gas Hot Water Heaters

hi, your answer is in your question on no. 1, the key is balance, if you want heat to travel to a room, you need the cold air to go away from it, through your cold air return. as for no. 2, i use my blower in the summer just to circulate the air, but in winter i think it might cool it down quicker therefore negating any possible energy savings. no. 3, i drain and flush mine every spring to remove any scale and slime build-up, i noticed alot of buildup on the bottom, and after the first time i flushed it out i had to lower my temp setting, so maybe its worth doing, however i now use a boiler to heat my domestic hot water in the winter, but in summer i use nat. gas. it seems to recover quicker now. insulating probably would not hurt either. as far as tankless heater go, i have only heard good things, but have no experience with them. good luck.

1. Insulation and a balanced system, did you have an addition and not correct the plenum?

2. You may need professional help...

3 & 4 yes

5. What is your hot water load? How many bathrooms, washers etc.? Checkout Marathon water heaters the 80 gallon is more efficient than the 50.

If the scale is tough replace the anode too.

I purchased the 85 gallon Marathon, and have nothing but great things to say about it.

My problem is that I now want to hook up my solar water heater to it. (open system in So Fla) The Solar "experts say that I should throw it away, and buy a cheap crappy one from them, that has been modified for solar use. Another two legged shark.

I am now contemplating a water circulator pump, or the lobster to bring hot water to the rear bathroom as it is now about 80 ft run from the water heater to it.

Have you considered a small on demand unit for the rear bath only?

The on demand units that I have seen are 20 amp or more. I was not looking to have to run a new power supply th that room. A small pump would work off of the existing power in the room. I am too cheap, lazy and what ever else my wife says.

I planted some bird seed. A bird came up. Now I don't know what to feed it.

use 110V

all water heaters are essentially the same in operation why would a cheap one be better

Because then they would be able to sell me a new water heater.

There is a plumbing diagram that routs the hot water from the roof to the drain valve on the bottom of the water heater. The cold water goes to the roof and the house is fed from the top of the water heater. I do not remember how the circulator pump is plumbed. Does just the solar circulate, or does the solar and the water heater tank circulate together?

Just the solar circulates.

The hot water from the roof goes to the heat exchanger inside the water tank.

Otherwise you got it.

Thank you. Now if I can remember that when the shingles are done on the roof.
