If I use this product, will it take more gas to run my hot water tank?

sure...but not much more. more to the point you are not wasting gallons of water waiting to get hot water at the sink. this was one of the best home improvements i made and i made a lot of them

That is a possibility, especially if the hot water piping is long in distance and/or if it is has a tendency to loose temperature over the piping run, then the water heater will fire to bring temp back up. I don't think that actual cost would amount to much as natural gas is still fairly cheap. Good Luck

I have not seen any appreciable increase in my gas bill. The advantage of not having to let the water run for extended periods of time to get hot water far outweighs the amount of gas that may be used.

We have used the Grundfos for over a year and have not noticed any significant change in our gas bill. We use the timer so it runs several hours in the morning and evening (we work during the day). It has eliminated the problem of us having to run water down the drain for 3-5 minutes to get hot water. My wife loves the immediate availability of hot water.

I would suggest checking your propane regulator for proper operation. Possibly test the LP gas pressure at the connection going to the water heater.

Just got it installed at end of season so I am not sure how good or fast it will work. We had it converted to natural gas and did not change any other parts on pool or filter system. Only hassle we had was running the natural gas line to heater.

Yes it is gas not sure the run time on a tank full least 8 hrs I would guess

No; you would need the complete Watts Zero Waste RO system. The Zero Waste system forces the 'waste water' back into your hot water line, essentially storing it in your water heater until it is flushed out each time you use hot water.

I believe you'll need to get "disposable tank regulators" as opposed to the large dual guage regulators you would use for a full size. eitherway, it has to have a regulator, or gas will release at tank pressure. talk about a bad day.

No. I wouldn't. This is an expansion tank, not a holding tank. Only holds 2.1 Gallons anyway (as mentioned in the main product title.) That size is just to compensate for the difference in physical space required between cold and hot water. It requires pressure to hold that 2.1 gallons as well, otherwise it gets pushed back out.

Yes you can, I've used water and the heater,runit for 2 cycles and they come out great.
1707155
Yes. That's what I use mine for. You need to turn the gas up and water flow down when the water is colder. If you live in a colder climate make sure to clear the water heater before winter. The copper tubing inside of mine burst over the winter here in Oregon.

Sorry I can't help with that. I have always used gas. It's the capacity I was after.
1861021
YES! That is one of the main reasons I bought this unit. It's faster than my gas cooktop at boiling water.
1707160
Yes it will. You can get water super hot by using more propane and less flow. On the other hand you can get warm water by using less propane and higher flow. This unit is made in China and is not high quality, it has very thin metal and is flimsy. If you are careful with it and don't bump it around it should work.

According to the instructions that came with it you should be able to siphon gas from the tank. However, as of now I have only used the sump for removing oil from the Engine and it works well for this job. I have not as yet tried to siphon gas with it so I can't answer how efficient it is for that purpose.

Not enough info to answer. The tank must be specific to the water heater and not to the R/V.

Yes, to a degree. I bought this hose for that express purpose but you have to realize the nature of propane. The bigger the tank used typically means the less total use of the propane you get. Depending on waht type of appliance is hooked to a tank that size, you run the risk of the tank "freezing up" and blocking the relase of the gas. This is typical with most types of heaters as they tend to draw the gas faster than it can convert from a liquid state the further down the liquid is in the tank. So, small tanks work best or be prepared to allow a big tank to thaw from time to time to get be able to use it's full volume. Yes, to a degree.

No. This just switches the gas on and off. If everything else is working (not leaking, lighting promptly, burning clean etc.) this won't affect efficiency.

It might, I have never tried it but I really don't think it will be as effective. I am 99% sure you will need gas.
