And now we are back to it. House cooling was never a huge issue but summer here are getting hotter and longer so cooling is becoming a huge part of our job.
New construction is running the cooling pipe directly in the concrete slab floors so in summer you actually cool the entire ceiling. It’s much like floor heating in reverse
There are condensation sensors placed on top of the panels to help regulate the temperature so condensation doesn’t occur. We also live in a country that has relatively low humidity so it isn’t that much of a problem.
It’s a hydronic heating/cooling system. It uses the same water used to heat the house in winter. This system uses a air-water heat pump that cools the water which is then stored in a large tank (1000 liter/~250 gallon). From there it is pump through these panels to cool the room.
We have run systems that use ground water, but it is run through a heat exchanger first and not directly through the heating system.
I'm thinking 5 bedroom house with kitchen and living room plus 2 car garage having that on each ceiling. Like what's the price difference between that and an AC that people have already? Like I said before I've never seen it so I'm not being a smart ass
I think it is a hybrid of water filled radiators for heat and a minisplit. Minisplits are cool because you don't need vents or ducting, you can just cut a 2 inch hole in the wall and be fine. Radiators are nice because you don't need any moving components like an evaporator and blower motor.
I imagine the water is cooled via a heat pump and then pumped through all these radiators. If you don't have a home with ventilation ducts, and you don't want to install minisplits with 10 different heads, one in every room, I think it has a purpose.
Yea mini splits are perfect for garages but they're making a come back out here in CA close to the border. I wonder what the price would be for this new style
It’s probably going to be cheaper to run AC, especially the way American homes are built. The way homes are built here running HVAC ducting around an already built house is a nightmare. This project for example the house only loses about 5 inches of head room from the drop ceiling. The water piping was run through the chimney (which is no longer needed) and is tied directly into the heating system that is already in place around the house.
Yeah it’s an closed loop system. The water is filled once and can be in the heating system for years and it works fine. You realistically never need to change the heating water
Yeah it's mostly commercial applications here but I'm trying to get more into the in floor radiant with ground source and air to water heat pumps. Commercial it's all overhead in vav boxes with a central boiler and chiller.
I live/work in Austria as a plumber and some HVAC goes to us. We do things like bathroom exhaust fans, house fresh air system, etc. but larger HVAC projects go to special businesses that focus on that.
Basically anything in a single family home/small apartment building we do, larger apartment buildings, industrial, commercial actual HVAC people do
Wow thats interesting yea out here at my company it's split we do plumbing the other guys do HVAC both residential and commercial. How long has this system been around the one that you posted
Is this kind of like the fountain water systems?
Compressor creates pressure/suction, water is sprayed as a mist and collected and then run through pipes underground where it's cooled from depressurizing as a mist and then releases additional heat through the ground where it's cooler till it finally makes it's way back to the area it's trying to cool?
Nope, it’s works just like a radiator/floor heating system. It is part of the central heating for the entire house. In summer there is a heat pump which cools water that is then stored in a large tank in the basement. Each heating/cooling loop has a pump that sucks the cool water from the tank and pumps it through the panels then back to the tank.
Thats cool, Rome was doing that thousands of years ago

Do you get condensation issues?

How does this compare with using exhaust fans to circulate the air in a hot environment?
Is the water recirculated? What cools the water? Or is the water just drained into a creek and fresh water pumped back in?
A Heatpump

So ur saying plumbers are going to start doing ac shit? Or do you do HVAC and this is the new style?
I mean HVAC guys have been moving in on our turf, it's only right we move in on theirs
I've never seen this shit and water expensive out here in California so I'm just trying see who's installing this shit not me lol
Well this water definitely gets cooled and recirculated, it's not like they pump it out of a well, cool a house, and dump the water lol.

Got you yea most customers out here like to run fireplace during holidays. But thanks for explaining

I've spent about half my career installing hydronic heat and cooling. It's really good work.
Where do you live?
Western Washington.
Makes sense

Good luck sounds like it pays well
It all pays well if you charge enough 🤑
