Will installing one of these units cause the water heater to run more often, in turn raising the gas bill?

Actually, I have found the opposite to be true. I cannot say it is a drastic savings, but I know factually -- my natural gas bill has ebbed down. Moreover, my water usage has also dropped -- substantially. Just an observation though: don't install it in the master bath if you are a "light" sleeper.

you circulate a small amount of water back to you water heater with this unit so like me you are thinking you are reheating or making your water heater run a little more, which you are, however, if you run your water at the faucet for a minute or more to heat it up, you are also bringing in outside water into the water heater which is much colder than the water that is recirculating causing the water heater to run anyway and possibly longer depending on the incoming temp of the water and how many gallons you run to get the water temp to what you need. If water conservation (cost or availability) is an issue (which availability may soon be the overwhelming issue for all of us) then this is the way to go. cost is very minimal. If you use very little water, and your other faucets / showers are close to the heater and heat up within 4 to 6 seconds then I would go with a 2.5 gallon under the faucet water heater, or better (if you can afford it) is an "on demand" heater, either way you have very hot water instantly. I have both the laing circulator pump at work and an under sink water heater at home. Both work great, just depends on your needs. The laing was installed at work to conserve water (trucked in 2 times per month) and because it circulates (85 deg on and 94 deg off) it keeps the water line thawed out and just a little natural gas is WAY cheaper than electricity or the water we truck in. At home, we want very hot water at our faucet (zero loss of water) and our other faucets heat up quickly so no real loss. Love them both. The Laing and the under sink heater (storage unit) will ultimatly cost the same (installation and parts are offset). THe Laing gives 95 degree water (the hot stuff follows pretty quick, the under the counter is instant, but either one makes your life nicer and you no longer have to sit by the faucet. I have since installed both systems for friends after evaluating their needs.

It's very noisy, I have to leave the water in the sink running for over 15 minutes, it's better than running the shower on full volume, makes a difference on water bill.

Not at all, but this means you might not be getting enough juice to the unit. You need a 200 Amp panel, two heavy cables (6/2 and 6/3) running from the unit to the electric panel. And you need to have 2 upgraded breakers at the panel. Also, if you have a lot of electrical usage at any one time (dishwasher running, A/C cranking, TV, and all the lights on), this may strain the system a bit for the short time that you use hot water. And, it also depends on the model that you bought and if that model accommodates the house size and family that you have. I have not had any issues with this unit so far. Then again I live in FL and I never need the water to be all that hot. I keep the temperature setting at 117 degrees and that seems just right. However, I do need to install a descaling system to prevent any scale buildup inside the unit, because FL water is hard water. All part of my master plan. ;O)

Yes i highly recommend add on heater. It will keep water stay hot longer time.

Sounds like a pressure problem, maybe too many gas appliances on at same time.

I have installed both, natural gas as well as propane gas units. It will run on either

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 think this can replace your thermostat. You didn't say if the system was electric or gas (hot water) heating but the heavy current is probably being handled by a system relay. You can download the manual and installation document from Honeywell for additional information, and/or check with a heating contractor to be sure.

This water heater requires a steady flow of water, it will automatically cut off it the water stops, plus if water flow is not steady the water will get hotter with less water which could result in getting burnt. You set the temp control which controls the gas and you set the water flow separately and I think it requires the water flow to be steady. If you have regular water flow this is a great water heater and I highly recommend.

There is a nylon drain plug outside on the panel where you access the gas and the electric connections. Be careful not to strip or break the nylon drain plug. Also, if the water heater was connected the water will be hot.

No, but turning down the thermostat on your water heater would do that, as well as save you money on heating your water higher than you need it to be heated. Just search on the internet, "how to turn water heater temperature down"

no. basically what this unit does is keep water from a more distant water heater warm, so that you do not need to wait as long. I think that it would be very poor for what you want.

I can honestly say no. Although I can't put a dollar figure on it, I noticed only a slight increase of my electric bill. It far outweighed turning the heat on, creating another bill. Hope this is helpful.

I think it is a trade-off... Our main gas furnace does not come on as much, but the room the little heater is in is much warmer than it is using the gas furnace alone. In the end I think the electric bill goes up a little and the natural gas bill goes down a little. This being said, I liked this heater so much though, that I bought another for a different place in my cold Michigan house.

Yes it does. For one, it takes a while to heat up. And for another, I had it running more than 12 hours a day. My electric bill went up by more than half.

No, sorry, you'll need to upgrade to a 400 amp panel, this unit will provide every bathroom in your house with hot water running constantly 24 hours a day. I built new so it was easy but well worth it when you consider you don't pay a dime for hot water until someone turns on a hot water tap. What's really great about this unit is when you want hotter water it's instant, no waiting for a conventional unit to build up 40 or 50 gallons of extra heat.

no,keep it simple buy what is designated for your heater read info. on this one,just in case here it is,Don't buy this one unless you buy a new water heater and have someone qualified to run a new line that is 240v(10,000 watts, 40 amps, 250 volts, 60Hz capacity)

As a contractor I have installed 2 within the last 2 yrs. One was replacing an electric conventional w.h.. The other was replacing a propane conventional w.h.(when they had trouble with provider last winter) Both families are happy with the purchase and have reported at least a $50/month savings on electric bill. I did have to install a water saver shower head on both homes to keep the showers below the max g.p.m. rating for the units
