Hello, I have waste cold
The water coming out of my tap is always cold, even in the height of the summer. I live so close to Lake Ontario, which is such a cold Lake, that the water will always be cool. I would like to connect a "radiator" to my cold water system to be able to cool down my house, similar to an air-conditioner, using the "waste cold", from the tap.

If you are planning on just using water from the city's waterworks, then I see 2 potential issues:
This close to the lake I assume that ground water is pretty shallow, so you wouldn't have to dig too deep to bury an underground coil.

I'll save you a little work. I've tried the cool water through a radiator ( fan coil, air handler, radiator with a fan behind). It doesn't function so well. The water needs to be about 1-5 deg.C to be effective. I circulated 12 deg.C water though a large fan coil and it did cool the room, but the humidity was still there. It felt uncomfortable. The temp. of the heat-exchanger (radiator) needs to be quite cold to wring the moisture out of the air. The best bang for the buck is of coarse is a mini split. Or better a geo heat pump. Study up here you can DIY. Randen |

If you are right on the water you can do it but as Randen says, the water needs to be quite cold if you want proper de-humidification. If the incoming water is above 5C, you can get cooling but not enough de-humidification and a heat pump may be necessary to bring the temp down some.
Also, if you are using city water, be aware that it is illegal to use and dump city water in Toronto, even through a heat pump. If you need help, let me know as I am in Toronto too. |
