Heat pump water heaters are growing in popularity among homeowners across the country. But what exactly are heat pump water heaters, and how do they work?
Great explanation, Thanks.
Very helpful to make a decision from.
I would imagine placing these in the attic is ideal since attics are usually hotter all year round
But that shit is load bearier and you want this thing fail and start leaking. I would prolly just run a vent or somehing and keep this in the basement.
soooo, what would make the most sense with this heat pump water heater is to have the condensor(heat pump) located outside, like a normal hvac system, to where it can pull all the air needed. Most ppl have a water heater, in a garage or small space that is not nearly enough room for these to function adequately.
I heard If it is in garage, it keeps the garage super freezing cold!
Super freezing cold? lol - NOT! I had one and it was in my garage. The cold air is a nice byproduct of these heat pump water heaters but they aren't putting out nowhere near enough volume of cold air to make a garage freezing cold.
So, during the heating season, the furnace provides the heat and the water heater cools the area around it, and the furnace then replaces this heat. But in the cooling season you could actually benefit from the cooling effect. It doesn't seem like a benefit for half of the year.
Very helpful! I live in cold Minnesota, so I think I'm going to pass.
yeah how much power that compressor uses? what happens in a power outrage situation. I am a plumber/gasfitter and I don't buy heat pumps at all, you will spend so much power rather the clean natural gas. So what if natural gas comes from a non renewable source, your electricity too comes from there, but now you will spend 3x more by not using natural gas
Ok so what's the advantage of a heat pump water heater over solar hot water???? Why would climate have any bearing on a water heater that is inside a climate controlled HOUSE, its not sitting outside on the back porch in the uncontrolled elements???
Mine is outside. Just installed today. I live in Melbourne Australia. Our winters are pretty cold so I have my fingers crossed
Heat pump water heater is not efficient. I don’t think it is the way for future water heaters
Heat pumps and their 300% efficiency are a big con and they go against the laws of physics. If that was the case, i.e. 300% efficiency, then why can't we install an 2nd pump in series from the 1st pump, and give out 3 times more, i.e. output 9 times from the original input? Could even try a 3rd pump and give out 27x output.....The 300% efficiency is a big con. People tried to build perpetual motion machines in the 17th-18th century, until physicists formulated the laws of thermodynamics and proved this was not possible. No machine can be > 100% efficient.
You just don’t understand the physics.
He did not say they were 300% efficient. He said they were 3-5 X more efficient that the alternatives. No system is 100% efficient, which is what you seem to be assuming. If a conventional system is 60% efficient, then this would be 50% of 50% more efficient. 50% of 60% is 30%. So the comparison of the old system to the new system is it's gone from 60% efficient to 90% efficient. Now if your original system was more efficient in the first place, say 70%, that's great. The heat pump system might be 30% more efficient. The math says that would be 91% efficient. I am just ball parking the actual numbers but that is how the math works.
