My Geospring

[Brian26]

For those in Massachusetts my sister in the Boston area is going to buy one after I told her about mine.

There is a $750 rebate available through mass save. A Massachusetts zip code on lowes shows these on sale for $999. Total cost with the rebate would be $350. A federal tax rebate of $300 is also available so you could get one for $50.

My 80 gallon energy sticker says $169 1407kwh
Are those energy #s above for the 3rd gen 50 gallon?

Cable man ,what is your temp setting?

Im at 120* basement is holding at 70* even though temps outside dropped last night.
I guess ill be holding off on turning the central a/c on!

 

[Seasoned Oak]

The furnace /woodstove room goes to 90 degrees which is in the basement in order to keep the house above at 75

Thats just slightly above my 50 which is $162 at 1351Hwha at 12c KWH, and it is 3rd generation.Not bad for the 80.Mine would be around $135 at 10c KWH. Only issue so far is at 120Deg i can get 3 to 4 normal showers back to back except when the wife does on of her hour long showers with the hair conditioner,then its only 2 . I could probably bump it up to 135 for those times. The Phone app and Module were you can adjust the temp from your smart phone would come in handy. Its $49 for the module.

1hr long shower! Crazy
Im higher then the 12c kwh, ill have to see how much my bill goes up each month

80gal sure is big, prolly should have done the 50!
Stihly dan that 140* is in hp only mode? I thought is maxed out at 125* in hp only mode.

This is in hp mode, temp setting has nothing to do with mode. It will not run as efficient with the lower delta T, but dehumidifies a crap load more.

 

[STIHLY DAN]

It seems this unit could recover even faster than a regular 50 Gal unit in hybrid mode if im not mistaken it uses both the 4500 watt heating element and the heat pump simultaneously. It also has a high demand mode and an electric only mode, I doing my initial warmup in heatpump only so as to get maximum area air cooling and humidification and lowest KW use. 3 birds with one stone.

No they do not run simultaneously. At least 1st and 2nd gens didn't. Boost is hybrid but turns electric elements on sooner than hybrid. Conventional is the fastest recovery.

 

[STIHLY DAN]

ID say standy loss is minimal in the HPWH iv been checking the temps of the external heat losers like the fittings and pressure relief valve. the hot water outlet is room temp when theres no draw,only place i could find a thermal leak is the Pressure relief valve which was about 85 degrees all the time.

I believe 2nd gen was 1/4 degree per hour heat loss, 3rd gen 1/2 that with its extra inch of insulation that all heaters have now.

 

[STIHLY DAN]

Have there been any reports or issues with the condensate pump drain freezing up in winter if it's piped outdoors?

It does not produce condensate in the winter. The air is to dry, thats why people run humidifiers in winter.

 

[STIHLY DAN]

Whats the 80gal use? I thought i read 600w max. I did see those 2 online but only one style 80 gallon

3rd gen is 550 watts, 80 gal only has 1 listing because they did not start making it until the 3rd gen. previously could only get a 50.

Same as the 50 so must be just a bigger tank ,same heat pump.

Prolly more coiling, still alot more expensive then the 50

 

[STIHLY DAN]

yup, you both are correct.

 

[Nelson]

Stopped running bout 1 hour ago, its aproved by an 11yo after her shower so far!
Expansion tank was 34 bucks at my buds cost, prolly not needed but his people said install it.
Sure sucked the humidy out of the basment!

Congrats on the install! I'm looking at one myself to replace my current gas fired (propane) hot water heater. I'm curious if you are measuring your humidity in your basement - if so, do you know how much it dropped after installing the Geospring?

Thanks!

I stuck a sensor from my acu-rite weather station down in my basement. Not really sure how accurate it is, but humidity stays around 69-70% and drops very little once its running maybe to 67-68%. Feels good and doesnt smell down there, if it did im sure the wife would let me know!

 

[Seasoned Oak]

While the geospring ,may alleviate mild humidity it dont replace a HD dehumidifier. ID say mine runs 20 % less but its still needed or the RH goes into the 80s. Takes a week to fill a 5 gallon bucket,which my dehumidifier could easily do in a day.

 

[Nelson]

thanks for the feedback. Yeah, I'm not anticipating being able to get rid of my dehumidifier but even a 20% reduction would be nice given how much juice mine sucks.

 

[Seasoned Oak]

Im monitoring the Kwh used by my dehumidifier with a killawatt meter,so far its about $3 a month set at 75%. Ill set it at 70% to see what the dffference is. Im sure the Goespring is helping with these numbers ,but i didnt check it before i got the Geo.

Will drylocking basement walls and floor help with basement humidity? I love to sprayfoam the whole thing but way too expensive.

Except in cases where actual liquid water is intruding, most basement humidity is coming from humid outdoor air entering the space, often through gaps at the sill plate around the basement. Alternatively, if the upstairs is not AC'ed, it may be comfortable in terms of relative humidity (RH) up there, but the same air might have too high RH in the basement due to its naturally lower temps.

If the upstairs is being AC'ed, then the problem is usually that the basement is getting humid air leaked from the outside AND cooling from the upstairs at the same time (by conduction through the floor).

The solution is usually to airseal the sills, which also makes the space a lot warmer in winter and saves on energy bills year round. Airselaing the sills by sprayfoam is usually a good approach, and is MUCH cheaper than trying to do the walls.

One test is to block the windows on a sunny day and see if you can see any daylight around the sills or other utility penetrations, basement doors, etc.

 

[cableman]

Ok good, i did the poor mans sill sealing with great stuff cans, worked well! Next is windows.

 

[semipro]

I agree with what woodgeek said but would add that concrete is water-permeable and that water will tend to move from the wetter side to the dryer side. How much water is coming through the walls will depend on exterior drainage and waterproofing, etc.
You can quickly get an idea of how much water may be entering the basement through the walls by taping some clear poly up on the wall so that water coming through is trapped by the plastic/tape. How much condensation is forming on the wall side of the poly will give you an idea of water entry amount.

I was actually surprised at the Dehumidifier power consumption. i thought it was a lot higher(may have been before geospring) I can live with $3 a month At 75%. IF 70 % is not much more ill go with that.

 

[Seasoned Oak]

Trying to maintain 70% humidity is 4x higher or $12 a month so im setting it at 75% at $3 a month along with help from the Geospring i should be OK with the boiler rust.
