Would this pump be appropriate for a hot-water boiler overflow? My boiler occasionally vents through the overpressure relief valve and wets the floor

Have your boiler serviced asap. There is a problem if your relief valve is tripping at 30 lbs pressure

I'm sorry but I'm not an HVAC guy and really couldn't offer any technical advice. I only know of the application in my system which is to drain water that's been removed from the air- dehumidified. Sorry I can't be of any assistance.

Probably, as I am just an average home owner. The biggest issue I see is trying to get it installed. I was replacing a broken unit, and the mounting screws aligned easily. I don't think the temperature of the water would effect the operation of the unit.

Wanted to use it to drain water out of the bottom of my hot tub. Not enough power to do this. Doesn't even work now , probably because it was submerged under water.

I don't think it will take the heat. Run a pipe down to 20" from floor and slide a bucket under

I am using it for the entire house as a recirculating pump. You need to talk to your plumber, who is better prepared to answer your concern. My feeling is that it will not work for your case.

I am not using the pump in that type of configuration. Suggest you look at the specs to figure this out.

yes this circulator pump is mounted on the side of my hot water boiler for baseboard heat

it does over heat the pump use a volt regulator you can buy one on ebay for six dollars.

Only use water in steam mops. If you add solution to it, it will clog up the the tube that goes into the boiler which could causes a pressure build up and explosion. This is to be used in Hoover FloorMates or with a mop and bucket

We bought this pump for our utility sink in the basement. It works well for us, pumping up the pipe 8' in height. You may want to check the manufacturer's specs if further information is needed. Sorry I could not provide further information.

I think it would do fine over a small circumference fire (relatively modest base size. The handle should be fine as it is well above the base. And the spout opening is fairly small, so a steady steam stream should be easy.

It's a good pump, moves a lot of water so if that's what you want to do it will work great for you. I installed it as a sump pump in a basement that gets flooded. It works fast.

I use this pump for pumping water into my cabin from a 55 gal drum.I built a stand to elevate the drum above the pump then I let gravity do the priming.

I am not sure about your application but if the previous pump was vacume(pressure pulse) operated, this should work for you.

It can go in if overhead clearance is enough to operate the relief valve, and if the emerging steam will not harm the top of the enclosure. Need ~ 3+ inches.

No problem, I use it as a pool cover pump and sometimes I have it running dry all day. It's a GREAT PUMP. Just be careful of the plastic pipe parts. I buy extra plastic parts online.

the pressure will not reduce unless the capacity of the pump is not sufficient. most of the time these pumps are way more efficient than the size of the hose so I wouldn't worry about it

Carl G I would like to know why you needed an oil lubricated pump? Changing to wet rotor may be an issue because of the clearances...if it stops it might only a small particle...I once had some system "goo" hat stopped one...it took washing it out with diesel to get it back running. Both engineering submitals indicate the NRF22 is about 2GPM less than the LR20BF at 10ft head...so here's the thing...depending on what system youre installing it on...most systems were designed for 160f DHW or 180f HWH water so by putting this in (I dont know your system but I would do it) you'll have a slighting lower flow rate...in DHW who cares as its no big deal...BUT in a HWH system your control valves will open more and this is a seriously good thing in modulating valves. There will be a larger delta T so I'd also lower my boiler temperature by at least 20f assuming youve some form of condensing boiler...this will help ensure youre in condensing mode. Circulate fluid...not temperature and you'll save a lot of money. Make sure your side stream filter is clean and check it a few times in the first 1-2 months because the more flow means the more crud is likely to get back to your HEX...if there isnt one put a Y strainer in and add a "sock" on the screen for a month or 2). A possible problem is how many zones open/ resistance decreases across too many different circuits/ zones...too many and there wont be enough. The system I installed this on it is actually the primary circulator through a 2xwall HEX serving the HWH off the DHW system...it works so well Ive been promoting it/ its been installed on 3 systems in this last year (its not my J.O.B but I do design energy and conservation projects as is my profession). Last, make sure the expansion tank is on the pump inlet side/ the return (DHWR or HWHR)...these high speed pumps cannot handle even a minimal bit of cavitation. All the best

Yes. Should go thru a pressure regulator, or fill slowly, or filter will not get a chance to do its job. But it did a good job of filtering .

Yes I believe that the pressure will go up but it may cause the pump to over heat and shorten the life of the pump
