ok I may have hit my bogy ..I cant stop obsessing about the perfect set up for heating & cooling my sps system

now I found this ground source heat pump for pools & cant stop wanting one now

www.millsco.com/suretemp.htm

what do u guys think??Is it worth the inital cost??

Id probably use a open type one connected to a well

I did alot of studying on these things & even saw a drawing of the first one built in 1945


hmm..after going back Im not sure that they were ground source type heat pumps mabey it is to good to be true

[eddie]

nope !it is true !

its the eco-energy heat pump

[jeff967]

so you are planing on running saltwater in a unit for fresh water pools? copper??

[ricksreef]

yup,jeff hit the nail,heat pumps have a copper
heat exchanger,making them toxic for use
in SW tanks.

[eddie]

on their price list they have titanum option with a 15 year warrenty...I read that 1 ton is enough for 5000 gals of water


on the air to water units.
on the ground source units it may not have that option..if not mabey they can be special built with one ..Im looking up other manufactures of groundsource heat pumps now also...


with the price of the air to water heat pumps,they even look nice & efficant enough to consider..with a titanium exchanger for less than $3000

mabey i can find or build my own ground source heat pump that I know is saltwater safe if I keep lookin

[eddie]

the ground source heat pump is a cupronickle alloy exchanger that is supposedly marine grade and should be safe I think


so.. if I understand correct I can get a groundsource swimming pool heat pump 145,000 btu's for $2885

[ricksreef]

the cupro in cupronickel is copper,be careful
i install about 40 of these a year,& have seen
low PH pools destroy the exchanger in no time.
avoid high velocity pumps & filter the water
before it enters the heat pump,either situation
can sandblast holes thru the exchanger.

thanks Rick

im still looking into them

I guess I was just real exited about my find Im pretty sure Id go with a titanium exchanger though the cupronnickel should be ok (i think)


the titanium exchanger modles are just about the same price they just use air to water & id love to use water to water but after looking at the efficancy charts

theres only a little differance in savings between the groundsource & high efficancy air to water every month in electric.

the high efficantcy air to water heat pump may be the better choice since some already come with the titanium exchanger for the same price


I found a aquarium that uses 15 4 ton groundsouce heat pumps on a shark exibit

I plan to contact the people who made them also

heres a link also to a place that shows how to make your own heat pump for aquaculter
they show a 20x30 greenhouse system

http://edis.ifas.ufl.edu/BODY_AE035

fixed link

[eddie]

since that link even refers to making a groundsource well water type exchanger I may make my own
groundsouce heat pump


the exchanger painted with epoxy they show can be replaced with a titanium exchanger Im sure

that would be the ultimate diy

I can get a used 2ton heat pump unit like they show

alot more real good heat pump info

i want to build one real bad now

Ive seen homemade heatpump chillers on ebay before

12,000 btus is 1 hp or 1 ton I think(still learning)

now Polar Eyes has a real nice affordable titanium echangers for saltwater in aquatic ecosystems catolog

anbody else know anything about building somthing like this either with a water to water or water to air exchanger & standard residental heat pump


ok I think I figured out part of it


this is a Materials List to build my own ground source heat pump about 2hp or 2 ton or 24,000 btus(that I know so far but need some help with)

1 Polar Eyes heat exchanger
4-5 hp for the well water to freon part (actualy with a little more diy a cheap $81.00 sweatwater 1" aluminum exchanger could be used here I think)

1 Polar Eyes exchanger for the freon to system water(not sure of hp needed to match yet .anyone??)

one 2 ton compressor

one reversing valve

one acumulator

???????do I still need a fan for cooling the compressor with a water to freon exchanger

I guess its best to find a 2 -2.5 ton residental heat pump used in good shape

scrap the air exchanger connect the 4-5 hp water to freon exchanger & tank system water exchanger......actual probably wouldnt be that bad a diy project..may have to take it to a heating & air place to have the lines vacumed & recharged with R22.....

the cheapest route would be a air exchanger though so Id love to try that first just to see how well it worked

the easyest way to do that would be to find a bad 4-5 ton heat pump & a good used 2-2.5 ton probably to swap the smaller compressor to the larger exchanger ....

found a place that sells water cooled chillers for aquariums

[eddie]

I found a place to get geothermal heat pump/chillers with Titanium exchangers for swimming pools

124,000 BTU's for around $3500 neat thing I learned also about heat pumps is you can make them where they have seperate loops to cool seprate systems from the same heat pump

124,000 BTU's seems like a over kill but the compressor would'nt have to run long & never know what may be held in the future

a aqaculture specific heat pump chiller 60,000 btus is over $6,000

Im still just brain storming but this geothermal swimming pool heat pump/chiller is stuck in my head now

shipping would be $115.00

so for this price just knowing Id have total control over water temps when needed seems well worth piece of mind now I just need to count up all my pennies to pay for one

just thought Id share my findings
