Given Poplar Drive only got stop signs in 2017, a light's not super likely. We have heard that it's possible the intersection can get at least partially redesigned, most likely to narrow the crossings, and there might be some short-term solutions (e.g., temporary flex posts) to at least partially accomplish that ahead of a full redesign.

Again, you literally are saying you think there are better ways so why even try using the national guard. This is the perfect being the enemy of the good. I dont claim it definitely will work, but what can it hurt? Murders are at all time highs over the last three years.

As far as I am aware, the national guard is fully funded by the DOD.

Also, why are you so content on doing nothing in the short term to alleviate the burden on citizens? Talking about enacting legislation, and reforming infrastructure, and the police are things that take a lot of time. In the meantime, do we just tell citizens get used to 500 of you dying a year and this is the new normal until we fix it a few years from now.

And this violence has not been going on for half a century, are you seriously? The amount of murders in this city has fucking doubled in the last 7 years.

We have never, and I literally mean NEVER had back to back years of 500 murders before the last two years. Never had three years of 490+ which is the last three.

There was only one year before the previous two where we had 500 murders, which was 1990. The population at the time was 1.586 mil, which is literally more than the population we have now, albeit slightly, but we still have more bodies today. This means homicide per capita is higher than it ever was in the 90s, fucking wild.

We are not at the status quo, we are well fucking above it. Again, this is why trying something new makes sense, we are dealing with unprecedented homicides. But hey, if you ain't feeling it I suppose it's just business as usual in the city, screw those poor ppl amirite?

No, just using the "hybrid" term in the way that most manufactures use it: the water heater uses a heat pump and an electric element, but can run from one or the other or both. Not talking about single outdoor units or split heat pump water heaters that put the heat pump outdoors. Air source heat pump for cooling/heating (with supplemental heat from the existing gas boiler & radiators) is a future project.

Sounds like you're considering putting in the same thing that I'm considering and for mostly the same reasons. Are you sizing up to a larger capacity unit than your current water heater?

OP, why do you have a hot water heater? If the water is hot, why do you need to keep heating it up?

I suggest you look into cold water heaters, you could be being scammed with that hot water heater jawn.

EDIT: or is that "hot water heater" is the same as "naan bread" and "chai tea" around here?

Where will your water heater be installed? In a basement, with no access to outside air?

I don't have one installed but needed a new water heater a few years ago and considered getting a heat pump model. I decided against it, and in favor of an electric Rheem Marathon, for a couple of reasons:

  1. Heat pump water heaters are more mechanically complex than traditional electric, with more opportunities for failure. This was the main reason.

  2. A heat pump water heater extracts energy from the ambient air and uses it to heat your water. If you're in a Philly rowhouse and your water heater is in the basement, the heat pump is going to be less efficient than it could be because it's extracting energy from your basement air, which is:

  • Heated by your home heating system, which will have to work harder to make up for the lost heat.

  • Limited in energy capacity because there isn't much air volume in your basement and it doesn't move around much.

So it's not as efficient as, for example, a mini-split heat pump you'd use to heat your house, where part of the system is outside the house and it can pull energy from the outside air, which is a "free" source of energy and also there's way more of it available.

I dunno man, I can appreciate where you’re coming from but I just don’t think it’s as easy as you’re making it sound to plant the national guard here as a crime deterrent. Who pays for it? The city, the state, the feds? If we’re gonna do it in Philly, why not other cities with worse homicide rates?

I’m not looking for a perfect solution, I just think the threshold for mobilizing the national guard is (rightfully) pretty high, and if violence that has been going on for half a century was considered below that threshold, we’d have seen it already. We already know things that will work (like, hey, maybe some gun laws so a teenager doesn’t have easy enough access that they can blast someone they get in a fight with), but we’ve decided in this country that we’re different and what has worked literally everywhere else just won’t work here (but no one can really explain why it won’t work).

There is a pretty bridge across the river, it's maybe a 5-10 min walk if you go left down the trail after you park in the main entrance off of rhawn st. Sorry I can't be more specific, I just remember it being a nice place to stop and take pics. wishing your family the best ❤️

I looked at it and decided to go conventional. But my reasons were additional noise and complexity.

If the HWH is in a heated space, then it should be fine. If it's not, then heating the water with the built-in heat pump would not be effective in very cold weather.

I haven't installed one but am about to take the plunge due to the tax credits available this year. So I've done a deep dive into the pros and cons. When you say "hybrid," are you referring to a single outdoor heat pump that heats the home AND the water? It's worth distinguishing, because yeah -- in general, air source heat pumps become marginally less efficient as the outside temperature drops. Just as in deep cold it might take said heat pump longer to raise your indoor temp by X degrees, it also takes longer to raise the temp of a tank full of water. When I see complaints online about heat pump water heaters, it causes me to wonder if people undersized the tank -- like, did they get a 50 gallon when their use patterns would've been better served by a 100 gallon?

I have an air source heat pump already that heats and cools my house. We also have an older gas boiler that does radiator heat as a backup. This winter, we used the boiler/radiators on exactly 20 days total. The heat pump covered the rest of the winter, no problem. But interestingly, I found that I saved money on the heat pump by eliminating programmed nighttime setbacks on my thermostat -- the heat pump worked more efficiently by maintaining temps over time than by having to raise them quickly in the morning, at the coldest part of the day. That kind of "high inertia" performance (for lack of a better term, I'm not a scientist) would indicate that maybe sizing up to a larger tank would be a good idea for a water heater.

I'm now looking at getting a *separate* heat pump water heater to put in my basement. The cool thing about these is that they are effectively air-conditioning your basement in order to heat your hot water -- they just move heat from the surrounding environment into the water in the tank. So in this region, I think there are some extra benefits in that a basement HPWH can dehumidify your basement and effectively suck up waste heat from boilers, hot water pipes, dehumidifiers, dryers, etc. But it does make the basement itself colder in those winter months.

Heat pump water heaters are slow, if you buy one with the same size tank as you're replacing you will be disappointed. Also, there have been improvements recently, mainly they hold the water at a higher temperature now and mix it with cold to reach the desired temperature and make the tank last longer
