i was looking at the waterless systems but the water in my area is very mineral so it would eat the insides and the waterless are a lot more finicky about the type of water going through than tanks. Besides, i got my tank for a steal. $450 for a brand new tank WITH a 1000W portable generator. both brand new. so the tank came out to be less than 300....
I was talking to some guys in the industry about installing an upgraded thermostat on the tank that can lower the temperature during the day but everyone said not to bother. That the new tanks are so efficient that it will fire only once, maaaybe twice during the entire day.
And now the biggest kicker. 1500 square feet house, the water tank, furnace and dryer are gas. furnace was off up until a few weeks ago. Two ppl houselhold. shower gets used daily x2 plus the drier is run multiple times on the weekend. My monthly bill comes out to be 45 dollars WITH the 15 dollar rental. So 30 dollar in gas...so now you're thinking...hey 30 to 40% better efficiency means about $10 savings right? wrong! Once i broke the bill down, i only actually used $3.41 in gas. the rest were delivery charge, this surcharge that surcharge, and the biggest part of the bill?!? $19 customer fee...
So here i am, thinking about spending thousands of dollars on a more energy efficient system of heating my water when in 30 days of use i actually spend only 3.41 cents in gas usage....WHATS THE POINT?! 30% better efficiency would net me a dollar and change savings!?!?! sure the delivery charge and all that other jazz is based on usage. but even all that stuff added up still came up to less than $20.
If you really wanna save on gas bills, you have to look at your furnace, your ducting, and be willing to lower the thermostat a degree or two. THATS where the huge savings are.
I'm actually looking forward to the next bill to see what the difference in gas usage is going to be with the furnace now running.
Yup, tankless is great for reducing gas consumption, but to reduce cost you need to deliver your own gas. Propane or NG tanks I guess, if it's even possible. Can someone crunch the costs/frequency of replenishment for this kind of self-serve gas tank heating system?
