Tankless propane vs tank style propane heater. the newer propane and natural gas tank waterheaters are required to be equipped with safety components which has driven the price of gas-fired tank style heaters up in the past couple of years. List prices around $800 for a 40 gallon good for a family of 2-3. Tankless already have the safeties in place and list for $1200 for the unit. If an "average" family of 3 uses 30 gallons of gas a month thru a 70% efficient tank style , the tankless at 84% efficiency would use 24.9 gallon of gas per month. At $2.50 per gallon of LP the savings per month would be $9.75. In 41 months the savings has paid the difference. The warranty for the tank is 6 years, the tankless exchanger is 12 years. The savings over an electric tank is vastly greater. If you burn Natural Gas, the cost to operate is even less. I hope all this helps. I have installed Rinnai, Bosch/Aquastar, Tagaki, Thermar, Saunier-Duval, Paloma tankless and Bradford-White, State, Rheem/Ruud, American, Master Mechanic, Sears tank style waterheaters for over 20 years. Rinnai excels over all the others. The vent is simple and the only caution is against a high mineral/lime content in the water. And the factory support is the best in the industry.

you’re either referring to the law (in Washington State, anyway) regarding rental properties, or you live in some place that has uber nanny legislators. And seriously? YOU don’t think YOU are smart enough to know what temperature YOU want YOUR hot water in your home? Any who, I don’t want the dishwasher to turn the electrical heating element on. Electricity (unless your using magnetic induction) is an inefficient way to heat water. It is better for my house to use hot water from my tankless HWH. I have a tankless HWH that will produce 190° hot water if I set it correctly. I have a dedicated line from the manifold that natal led between the heater and the Case Acme temperature regulator. I send 160° water to my dishwasher, and washing machine. (I also have a dedicated line that supplies 160° to a separate faucet on my sink that takes the place of the under sink contraption that crapped out a while back. (120° is the legal limit? Don’t tell InSinkerator. I doubt those gadgets they make can even go down to 120°.) I would use 180° water but I am afraid the water temperature alone might melt some plastic ware and also damage some synthetic fabrics. Here’s a thought, when it comes to how YOU choose to live in YOUR house, man up, and grow a pair.

Kinda late looking at this, but hit the below energystar.gov website for gas storage tanks. I'm spoiled on tankless, but not everyone is. Here is a link that might be useful: Water Heater, High Efficiency Gas Storage

Thanks. I am assuming given that I am not going to be using the air conditioner for 6 more months, I can drain it out and should be good? Wrong, during heating condensate is also produced. It needs to be fixed before both the cooling and heating season. I also suspect the condensate pump considering it is full, it will normally empty out once the float activates the pump but clearly there is something wrong with yours. The pump may have just quit working and need replaced. They are not that expensive.
