Very helpful. Thx!

I have a sanden heat pump hotwater system, installed mid winter in Melbourne Australia, it took 3.5 hours to heat a completely cold 250 Lt tank using 1.1kw per hour. In mid summer it can only take 35 minutes after a day's use by my wife and I, but our daughter hour long showers can make it run longer.

12:00 label is wrong

Simple, practical example of commonsense and observation (of what worked and didn't !)

That is from a time when flue gases could exceed 1000 degrees. Today even what is left of chimney venting devices flue gases will not exceed 350 degrees. When you oxidize a hydrocarbon (burn fuel) you create water and co2. In old equipment you could not let this exhaust drop to the point of condensation as the water you created was acidic from the co2 and would eat away the chimney,so high exhaust temps were needed. Modern equipment no longer uses chimneys as they vent through the wall with pvc. The flue gasses are encouraged to condense in order to pick up that latent heat that he describes in the video thus eliminating chimneys and bringing the efficiency of modern boilers up to 96%. A similar idea was used on wood stoves, someone got the bright idea to put an exchanger with a fan on the smokepipe of an indoor wood stove, big Mother earth news thing lol. This caused the flue gases to condense, create creosote and numerous homes burned down from chimney fires.

Also building with Passive Solar energy principles.

Yeah, real modern properly built houses cools & heats themselves. Just thru proper insulation and ventilation, reduces energy drastically for heating & cooling

@@Monno15 Earthships. No electricity needed just passive solar.

Heat pumps are still using refrigerant that's not environmentally friendly...

All these environmentally friendly devices have their downsides in using up resources and creating waste. There is no magic wand or perfect answer that will suit all countries and conditions. People must be left to choose what is best for them, not be forced into paying for expensive equipment which may not be efficient in their situation and cost them more to run. For we cannot put people in debt or poverty just to satisfy our own environmental conscience. Gas boilers and petrol cars may be the best for some people. Governments have no right to dictate what we may buy or use because of some imagined future scenario. The Earth is a volatile entity and is changing all the time including the weather, and this has always been. For what melted the ice ages when there was no industrialisation around? Most of what we are being told by ‘experts’ is only speculation and guesswork at the very best - and I am not a ‘denier’, far from it. I am concerned as anyone about pollution and the degradation of the natural world . But many of the ‘solutions’ put forward by the so-called experts are deeply flawed and create waste and pollution, and also use up massive natural resources. ‘Balance’ is what is required, there is no need to panic.

@@nicknevco215 lmao. it is a heater hence the name heatpump. it works efficiently down to an outside temperature of -13F, it works at even lower temperatures but the gains go down since it gets more difficult to extract heat energy from cold water/air. after a certain point its basically just an electrical heating system with no gains at all. if you had actually watched that video above......

I have to disagree here. If you take lifespan en costs into consideration, then the attractiveness quickly dissappears. Also you will have to do some very serious insulation to your home/building before a ground based heatpump becomes a viable option.

Granted we have a modern home (~35yo) that's well-insulated and being well-insulated was part of the criteria for NYSERDA qualification. The house is also all electric so we really benefited financially. But I can see that the energy needed to do what an older air-source heatpump struggled with is a fraction. Our electric bills have been cut in half since we bought the place (also due to other measures, like LED bulbs, updated appliances, etc.) An added benefit is that electric rates have been far more stable over the past ten years than fossil fuel prices. They've risen, but not like the rollercoaster ride that are gas and oil pricing.

@@bm5994 I think you might be focusing on ground-to-water heat pumps. Ground-to-air is an option even if insulation isn't top grade, and it's highly efficient. Water based heat pumps are pushed hard in the UK through grants etc and air to air or ground to air are largely ignored by agencies tasked with energy management, grant distribution etc. This may be because air based systems can be used for cooling and a cooling energy load in Summer would bugger up the government's rosy picture of progress towards targets for reductions in CO2 production.

amen brother! hahaha

Well, you're actually embracing the refrigeration cycle. You're just reversing it for the heating season. In summer, you're rejecting heat into the warm outside air to cool the indoor air. In the winter, you're rejecting heat into the indoor air to cool the outdoor air (or, for geothermal, you're heating and cooling earth instead of outdoor air). Point being: it's the vapor compression cycle being used for both heating and cooling (which it always is anyway). And you're not getting "500%" efficiency. Not even close. That's just a shell game you're playing because you're disregarding the heat being "stolen" from the outdoor air (or soil) by heating it up for cooling and cooling it off for heating. Big problem, of course, is in cold climates you're stuck having to go with geothermal because the air is too cold to try to cool to get heat from. In reality, in most climates, you'll still need to supplement in the winter time with resistance heaters or combustion of fuels because the availability of energy is just too low for high quality heat. I'm going to wait for ultra high efficiency thermoelectric heat pumps. No moving parts, same high level heat pump principles, and much more friendly to DC, low voltage sources like photovoltaics. No damned motors and coils and compressors and refrigerants and such. It's a couple of decades down the road, but it's coming. Then, kiss your R-whatever number chemicals goodbye for good! 👍

HUH?

@@mc2engineeringprof Are you high?

@@mc2engineeringprof Gas fired refrigerators are surprisingly efficient but they do use the refrigeration cycle. A small heater evaporates ammonia. This loops over to the condenser wher it’s cooled. Liquid ammonia takes up 100th of the space so creates a suction evaporating ammonia in the cold boil gives the cooling.

What’s the USV? Love the off the grid life! Glad to hear it Jeff, I’d love to hear about your setup!

Thank you sir!

I often day dream of having a heat pump power plant in which the heat concentrated by the heat pump in a tropical area or hot desert is used for generate electricity part of which is used for running the power plant in a sustaining manner while liquid air is produced to be use for air-conditioning and for powering vehicles that run on liquid air.

@@simon6071 A heat pump moves heat around. It can never generate more electricity than it uses.

@@nielsunnerup7099 You have a wrong idea about heat pumps. You obviously have no idea that a heat pump can create useful heat more than the amount of heat that can be produced by passing the same amount of electricity used by the heat pump to a heating element. In other words, the useful heat produced by a heat pump can be greater than 100 % of the heat produced by a heating element of 100% efficiency using the same amount of electricity. It is not against the law of physics. The heat above the 100% created by the heat pump comes not from the electricity but from the latent heat of air. That's why cool or cold air is created during the operation of a heat pump. If the heat above the 100% is used for generating electricity, then we have more electricity than we put in. If you use a blow torch to heat up and light up a large piece of wood, the large piece of wood will release more heat than the blow torch had release. That is not against the law of physics either because the extra heat comes from the wood not from the blow torch. In fact the sleeping prophet Edgar Cayce had predicted that there will be a liquid air economy in the future in which engines and some vehicles are powered by liquid air that expands when it absorb heat from the surroundings. I believe the liquid air economy will be possible with the use of powerful heat pumps possibly aided by solar power. The liquid air economy will have a beneficial effect in balancing the heat on earth even though I don't believe there is a problem of catastrophic global warming. If there is going to be a global warming problem, the liquid air economy will be a perfect solution because heat in the air is concentrated for heating and generation of electricity while the liquid air, a by-product produced, stored in carbon fiber tanks will be useful for air-conditioning and for powering air-engines in hot areas.

@@nielsunnerup7099 Now I tell tell that you are just an ignoramus who knows neither scientific matters nor the spiritual matters. GOOGLE: why can a heat pump produce more heat energy than it consumes "Heat pumps can seemingly defy the laws of thermodynamics, because they can deliver much more than one unit of heat (or cooling) per unit of electrical energy consumed. This is because they are extracting heat from around the evaporator and dumping heat to the environment around the condenser." GOOGLE: How can a heat pump be more than 100 efficient? "By contrast, heat pumps seemingly undertake the impossible: you get more heating out than the energy you put in. This is possible because we are using energy to move heat - rather than converting the energy directly to heat. As a result the apparent efficiency in terms of heat output is greater than 100%."

A non-redundant system. What a nightmare.

I would have a basic heat transfer system that pumps liquid down into the ground to transfer heat there, then brings it back up to run over the coils of the heat pump located in the basement with a second smaller system installed at the same time for the fridge... that way the system for the heat pump and the system for the fridge are not fighting each other in winter.

Nope total waste of money.

Check out Dandelion Energy, they are using closed loop bore holes 200m deep instead of ground coils. Less disruption to the surface and more consistent temperatures too make it a more efficient system. Still very expensive, but as they hone the technology the prices will come down, so keep an eye on it.

@@MrGonzonator Yeah much like solar initially was, there just is no real ROI unless there are huge rebates from the government, just doesn't make sense and you might as well use the air for your heat pump at that point.

@@jeffm2787 I've just read your original post again and done the F to C conversion... -30°C! That's colder than the coldest place in the UK ever on record.

Buy a chinese 2kW Diesel air heater for around $110. I installed one this winter, and in total I've used 0.8L Diesel! It didn't get below -2C this winter though, and I really only used it to prevent fogging, but it kept the cabin at 21C. It uses 180mL/hour and draws only 1.2A on 12V once warmed up. So I've emitted 2.3kg CO2 this winter from my heater. However a heat pump uses 10 times as much electricity, which in the US translates to around 750g CO2 for the same amount of heating, so you'll save 1.6kg CO2 if you drive as little as I do but instead gets a heat pump. So is it worthwhile? The Heat pump if far more expensive, so you need more hours at work, which I presume also has some CO2 emissions, not the least by driving there on more days? regardless, if you throw a barbecue this summer, and burn 10kg of charcoal, you'll also emit around 3kg CO2, so my advice, get a diesel heater, and cancel one or your planned garden parties, and you're in the green.

@@Tore_Lund good advice.

when comparing CO2 emitted shouldn't the CO2 emitted in the manufacture of diesel be included? Isn't it much greater than the the CO2 emitted in the generation of electricity used by heat pump, especially electricity generated from solar/wind?

@@timmathison8740 That's an argument that pops up on KZfaq often when talking about fossil fuels, but the conclusion is simply wrong: A barrel of crude contails 159L which when burned devellops 1.6MWh. An oil pump (donkey) uses 209Wh/per stroke, so the pumping only accounts for 0.5%, other types of oil extraction are more energy extensive, offshore 2% and oil sands even higher. Refining a barrel takes only 5kWh because the heat is recouped in the tower to preheat the next batch, tanker trucks and oiltankers are another few percent and so is sales and advertising, so on average 5-12% of the energy in oil is wasted before it gets into your engine. In other words, oil gives 12 times the energy back it takes to get it. So ask yourself; why has oil been king for a century, if it net uses more energy than it delivers? Has oil barrons been stupid wasting money every day through history? So you can fairly enough add 10% to the emissions of burning 1 L of diesel, to get the complete figure of emissions, but normally we only count what is burned, in electricity generation as well as in engines. We don't include workers health insurance or the diesel used in coal mines when calculating emissions from the grid.

Sorry I misread your argument: Yes, the heat pump uses less, but not much, you are saving around 1/3 the emissions, unless you charge by solar, then you save 95%. However a heat pump is more expensive, so the payback period is longer before it becomes cleaner than the diesel heater. In my example, I burned only 0.8L this winter, but if the dude lives in Alaska, A diesel burner is much worse. For comparison, I mentioned burning charcoal, and I actually missspelled: A kg of coal emits 3 kg of CO2, so he doesn't have to cancel a barbecue, but can just use 1kg less coal (and serve more sallad) at a single barbecue, to offset the slightly higher emissions from his heater by not getting a heat pump.

Glad to hear that!

Nearly all small gen sets pump out 220 as well as 110 and they are relatively cheap. I don’t recall seeing any of the 5000 and up Jen sets that don’t have both. The only problem that comes into play is having the plug which is usually expensive and often hard to get

The one good reason for gas, or wood stoves.

I have a deep cycle lead acid battery and a small inverter that I use for the boiler's circ pumps, t'stats, and water heater exhaust fan whenever the power is out. Don't even need a generator.

You’ll know we’re serious about the climate crisis when fireplaces and nat-gas connections are banned in new construction, and when new home siting reqts & house design reqts require optimal Passivhaus design (heat absorbing floors, proper roof/window shade reqts, full six-side insulation, and south-facing roofs at the proper pitch for the latitude (measured on 3/21 or 9/21).

That works for you when in heating mode, but against you in refrigeration mode.

I know this comment is 5 months old, but what we call heat pumps are both Heat and AC capable, that being said, in winter when it gets even below freezing, it CAN take the chill off, but you better not rely on it for your only heat source. The AC is amazing. Heat can be ok but to me, a nice Wood stove gives amazing heat comfy heat anyways. But yeah i don't think many people have just heat pumps with that being the only function. (where i live)

Actually the heat of compression is fairly sizable. Especially in water source heat pumps.
