If I put this on my old 1960's boiler,would this valve make it more energy efficient(since it is a newler design)w/o having to replace the whole unit?

all this unit does is supply the gas to your furnace. it has nothing to do with your furnace's efficiency.you will need to replace the furnace itself for that.

Mine did by at least 25% as old one was wasting a lot of gas by not starting and over fueling

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.

I didn't like the heat so I cheated.I used a 10,000uF capacitor in parallel with ~10 ohms in series with the 12V and valve.This allows the full 12V available to pull in the valve, but then drops the current by around half, reducing the power to ~1/2 of normal.I was afraid to let the valve operate for more the about ~15 minutes with 12V.Do a net search for fast relay operation or reducing relay power consumption for some examples.Good luckTerry

I used this replacement with a Whirlpool RO system. I also replaced all the valves though with brass and a shut off for easier future maintenance.

Hi, For me i looked at the honeywell brand and it did look the same as my old one.. so i bought it! and worked.. i can suggest that if it look the same then don't worry on the number brand unless looks totally different... it's only a suggestion. i took the risk and had my boiler running

This unit works great, I have four of them ranging from 4 years of use to current. You must have enough gas flow to unit at least 3/4 ".Intake and out flow as instructed. I you call Navien in NJ. THEY ARE GREAT in helping you with any issues. If you are not experienced with these units I recommend you fine a plumber that is versed with these boilers. The number is 800-519-8794 , I am engineer so following any repair of this unit will take some good knowledge of it's function.

Hi, unfortunately probably not. Your existing water heater likely uses PVC venting and this tankless will melt it during exhaust. If you have a relatively short, straight length then it won't be too expensive to vent. But you NEED stainless steel venting rated for this. While i'm at it, you may not have the right LP line either. check your line, if it's less than 3/4" you will need to replace it. I had 1/2" LP line and PVC venting. I ended up going cheap 50 gal electric. Was way to expensive to replace everything for me

You can use existing tubes. If the old tubes were holding air and maintaining a good pressure they should do OK.

I am not sure. Make sure the tank is not cracked around the little valve. I will have to replace the tank. Remove your old ones before ordering & check your tank.

I was having my bathroom remodeled and yes this was a replacement. I believe I did by the valve kit and if you don't use it return it. I had a contractor install mine. I like the style of this shower head but has low pressure and may have a water restricted which Im checking mine and will take it out .

Hmmm, regretfully, I have no way to measure the energy efficiency of the unit. On the other hand, given how poorly it seems to heat our front room even though it runs a great deal, I'm sure we will see a difference in our electric bill. Further, the oil filled heater that we formerly used probably is a bit more energy efficient (and overall, more efficient in heating the room) because the oil in the radiator hold heat.

Are you replacing the old one? If so, see if you can find the cfm (cubic feet per minute) of air movement the old has and compare it to this one.

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.

It is a plastic ball valve design so in theory it would work although I'm not sure if this would impact longevity of the valve itself. For occasional use it would likely be fine.

Sally, Yes. My reason is this: If you are replacing a old timer with new, the component parts down stream --the electronically-operated valves -- don't care what kind of timer you are using. For all "they" care, it could be a timer from another manufacturer. You are good to go! The only semi-difficult part of installation is getting the wiring correct when you make the transfer. I took a picture to use as a guide. Also, change the internal 9 volt back-up battery once a year. That will keep your programmed settings in memory if there's a power failure. Cheers, Jerry

I wouldn't worry about it. If all else is totally equal, it's life might be a little shorter; on the other hand, it could keep the compressor a little cooler, which could improve it's life and efficiency.

I'm not sure what size hose connections your old pump has and as far as horse power, the replacement pump is 1/2 the horse power as your old pump. and the replacement pump can be switched to 1/2 of that. So based on the horse power rating, it may not be the best suitable replacement. the way i found mine, was to do a search with the name and horse power of the old puimp and then started going down the search list until i found one that was as close to mine and a price that was was reasonable. prices can vary greatly so be careful.

I would ensure that your power supply will support 10 amps. The unit runs around 6 amps but the start up is more like 10amps. Hope this helpful. Great valve for the price.
