    Sliding Glass Door Safety

    Is it a metal framed door? Perhaps a simple security latch. Hopefully the picture loads... Maybe you put the slotted side vertical so that when it is latched , there is no way it can wiggle free. Or maybe one of those doggy screens with metal reinforcement on the bottom 3' and a sensor alarm...

    Solution for heat loss from inground pipes?

    When I first started talking to sunspot they recommended I do 15 tons worth of heat exchangers and to add a waterfall to dissipate some of the heat. I'm thinking I'm going to go with 10 tons or 5, still not sure. But I certainly could turn it into a hot tub I bet. chlorine costs for a 20k gal...

    Solution for heat loss from inground pipes?

    Great news, thanks! I'll let you know how it works, but in my case I know it's going to be awesome, and way long overdue, but I just found out about these heat exchangers. My property is a split commercial and residential. I lease the commercial warehouse and they run freezers and...

    Solution for heat loss from inground pipes?

    I'm preparing to add heat to my pool by adding a hotspot energy heat exchanger. The heat exchanger will be located 200' away from the pool. I am planning on installing 3" line to the pool but looking at the cost of insulated pipe is extremely expensive. 200' of 3" pipe holds about 73 gallons...

    Need help calculating total head to size pump

    This IS my first rodeo... Haha. Ok sounds like I need to do a little more planning and work on some schematics. I really appreciate all your input it has given me quite a lot of good info. Existing skimmer is the one that came with the /pool and has a 1 1/2" port and unless I add or replace is...

    Need help calculating total head to size pump

    Using the tdh calculator at 85gpm with 400' of 3" line adds 7' of tdh, the heat exchanger adds 10'?, the pump is about 3' below the discharge of the pool, what does the filter add to tdh? Using TDH can I then look at a pump curve to choose which pump gives me 85gpm at that given head? A two...

    Need help calculating total head to size pump

    Ya I was looking at a hayward 325 sq ft cartridge rated at 122gpm. The pump and filter will be at the pool, the heat exchanger is 200' away. I was thinking I would leave the old pump to save on electricity when I'm not heating because it seems like I'm going to need a 1.5hp (or bigger?) pump...

    Need help calculating total head to size pump

    Maybe skimmer is not the right terminology? I plan on adding a whole new pump and filter and leave the existing one still hooked up for when I'm not heating. The existing pump is a 3/4hp jandy. Not sure the filter size (not at home) but it's a pretty small cartridge filter. I was going to add...

    Need help calculating total head to size pump

    I'm also curious how much head should be added for the filter rated at 120gpm if it's say running at 85 gpm?

    Need help calculating total head to size pump

    The min gpm is 60. I am currently trying to size the pump right now along with a filter. I might step down to a smaller size heat exchanger but the distance is still the same. I was mainly concerned about the fact the heat exchanger was 24' below the pump and uncertain how that affected head...

    Need help calculating total head to size pump

    Thanks for the help with that. The maximum flow rate for the heat exchanger is 99gpm. I've been a little curious as to what happens if I go above that. But assuming I size pump and filter to pump <99gpm I will only achieve that when the filter is brand new. Also, so are you saying that 10...

    Need help calculating total head to size pump

    New to the forum but I've been browsing here for a while . I'm going to be finally heating my pool after three years of a chilly pool. Due to my unique system figured it was time to join and ask the pros! I'm installing a 150,000 btu heat exchanger, the problem is it's 200' from the pool. Not...
