Today is a BIG Day (We have HEATING) - Daikin Heat Pump Install

We've been working on this renovation project in Portugal for three years and have not had heating, running water or electricity in the house in all of that time. But that changes today.
Today is a big day that we've been working towards for the last few weeks and months.
We now have electricity in the house. We have running water in the house and now that the heat pump has been installed we will have hot running water and heating. And we're running all this on off grid solar power.
We'll show you the Daikin install (by a team of pros) and then we'll give you a tour of how the whole thing works and why we chose it.

I must have missed it but it looks like there is no driptray and floorwaste in your utility room also i prefer to run surface mounted piping in copper which makes for a neater appearance that pex looks like spaghetti thrown on the wall old school plumber here anyway still like your videos 👍

[@carolbulmer8253]

WOW!! This is PROGRESS!! This was quite something watching these men doing the hookups. Thank you, Kylie, for explaining the system.

[@jeantriplett8478]

In 1975 we built a home in Iowa and had a heat pump installed. It worked wonderfully for the 28 years we lived in the house and the present owners are still using this system today 48 years later. They have had to replace some parts but nothing major. We moved to Arkansas in 2003 and had a heat pump installed in our new home there, and 20 years later it is still working. Cannot say enough good things about this product. Economical, reliable, comfortable winter and summer....it also did the air con in summer. I am sure there have been improvements made since our install in 1975 but all to the good I am sure. Great job!!!!!

[@nickfosterxx]

Wow. I had no idea this technology went back that far. That is what foresight looks like. Hats off to you.

I live in Sweden and have an air/air heat pump to heat the 112 sq. m. house(no hot water) and it can still keep the inside temperature at 20 C when it is -20 outside.

[@katefinnegan8129]

I live in USA and all my pipes in the utility room are exposed. That’s how the house came it wasn’t something I chose. Who would want to have to dig the pipes out of the walls in an emergency situation when you have a leak and have to get to one of the pipes. Your pipes look very well organized and covered and labeled nicely. It’s not like you are serving dinner in there. Great job.

[@robgullen]

"utility room" a.k.a. "mission control" - fantastic job!

[@linrepboras]

Easiest way to describe a air heat pump is it's like a fridge but in reverse. In Sweden these heating systems are quite popular in (as you state) existing buildings since being relatively easy to install. If these systems work in Sweden they should be working better in Portugal. The data of your off-grid system would be very interesting, I dont beleive that would work in Sweden considering the short daytime (sun hours) during winter months wich is the period the system is needed the most. Final comment, Connecting the woodburner is smart, making use of the cosy fire in more ways then one. Thanks, guys!

[@Bobrogers99]

Re having exposed piping, it all looks so neat and orderly that I'd be proud to show it off! Re depending on solar panels for power, there would probably be enough heat stored in the tank to keep the house comfortable on a winter's night even if you shut off the heat pump until morning. But you won't have to, because batteries have improved to easily provide power to the compressor for many hours. Ten years ago this system would have been risky, but solar cells, batteries and air-sourced heat pumps have all become vastly more efficient since then.

[@MAKEDOGROW]

Yes, we’ve thought of this too (hence the test to see the temp drop when turned off) and during periods of grey days we’ll probably turn the unit off to preserve the power in the batteries. We also have a backup generator but really want to avoid using it.

[@vrvrhm8438]

I am wondering why the ventilation pump has to be turned off for the day time. I have heard that in England, for example, it is customary to heat the apartment in the evening and at night for a while, and during the day the apartments are kept cold. This results mold damage inside of house. In my country, it is customary to keep the house heating, also the ventilation pump always on, to avoid mold damage. The ventilation pump has a thermostat that keeps the desired room temperature constant. The air heat pump should be adjusted to 23 or 24 degrees in hot weather and then keep it on all the time. Also, the humidity outside does not move inside the house when the ventilation pump is constantly on. As we all know, moisture always moves from wet to dry, which in turn worsens air quality and causes mold damage at worst. If we switch off the device continuously, there is moist air outside and dry air inside, the moisture seeps through the structures. There will be no problems if the machine is on all the time, with a suitable coolness and the indoor air is suitably dry. The air source heat pump is kept on even on working days, even if there is no one at home and when we go on vacation. The ventilation pump is easily damaged by being turned off and on constantly. (Executive director of Sulpu ry, the Finnish heat pump association, Jussi Hirvonen.)

[@victorgscardoso]

@@vrvrhm8438 On a good insulated house you do not need to power off the heating. We have it all day long turned on and the consumption is quite low.Of course you are required some double/triple glazing and quite thick insulation layer for that.

Here in Portugal we call the utility room an "engine room"😁 nice work!

[@markshearer1831]

I like the exposed piping and wiring it's purposeful. Especially in this room

[@alastairrundall2175]

A friend of mine had a air sourced heat pump for his outdoor swimming pool. He put a poly shelter over it so that it could be used all year round, the amount of heat within that cover seemed extreme so we installed ducting so that the heat pump could recycle the warm air to heat the water. It worked a treat.

[@bekindfox]

I live in Switzerland and built a wooden house with passive energy level. I do have an air based heat pump and it works perfectly. The systems works because any temperature over 0° Fahrenheit (helps to understand better) is physically "warmth" or "energy". So also when here in winter there are - 20° Celsius, it does its work. Only problem I encounter is that whenever the temperature drops quickly, the pump needs a bit of time to heat up. So I have a wood stove and a fire place that I use in those cases to warm up the house for the max. 1 day until the heat pump is again on full mode. Congrats to your milestone!!!

[@victorgscardoso]

Looks great! I can support your intuition that your air-water heat-pump together with the solar PV modules, provided you have enough battery capacity, will make you through the winter. We live in south Germany, near the Alps and, on average, we have some 10-12 weeks with temperatures below zero, and from those we have 2-3 weeks where the outside temperature is below -10ºC 24/24h. We have also underfloor heating, and an air-water heat-pump with a 750 liter tank. The heat-pump struggles on those "below -10ºC" days, where the efficiency really drops, mostly due to the fact that the cycle must reverse several times per day to unfreeze the outdoor unit. It is not perfect, but 10 years ago the technology was not as evolved as today. On our case a geothermal heat-pump would be the ideal choice, but the original builder/owner did not considered it at the time of the construction works... We also have a 18kWp solar array with a total of 18kWh battery capacity, which provides us with 85% autonomy/year (we just need some external sourcing from the public network between November and March, mostly when the roof is covered with snow). So, with the portuguese climate and proper sizing of the solar power system, you will for sure be fine, even without the wood burner. We are also planing our move back to Portugal in a few years time, and I am still somewhat hesitant between an air-water and a geothermal heat-pump. So I'm eager to see the data you will be collecting from your set-up. Keep on the good work!

[@rexzietsman]

Expansion tank is to equalise pressure as the temperature rises and the water expands. Water expands slowly with temperature - hence the small equalisation tank 😁

[@Brigidz]

Yes. Traditionally in a one story dwelling the expansion of the water is relieved by a vent pipe which goes through the ceiling and roof space and extends above the roof line. As the water expands it will move up this pipe. More commonly now the pressure is relieved by a valve and pipe that's vented under the house. As this house has no underfloor space and the roof line is so far above the hot water tank, the expansion tank is installed to accommodate the expansion of the water.

[@Ragnar8504]

@@Brigidz In central Europe you frequently have a pressure relief valve at the cylinder that vents into a drain every time the cylinder heats up. More recently I've started seeing DHW expansion vessels like in this system (you can tell it's for the domestic hot water because it's grey, central heating ones are red, not safe for drinking water). This vessels is divided into two halves by a membrane. One half is full of water, the other air or pure nitrogen. Water doesn't compress, so as it heats up its volume increases. Gases do compress so with half the vessel filled with a gas the water has somewhere to go. As the water volume increases the gas is compressed and once the pressure is relieved (e.g. because you open a tap somewhere) the gas expands again. Works fine until the membrane gets old and brittle but these things are cheap. The wood burner needs a different kind of equalisation. If you've got, say, a gas burner you can simply shut off the gas as the thermostat says the water in the cylinder is hot enough. If your heat source is a wood burner you can't do that, the fire will continue to burn for a while and the heat that generates needs somewhere to go, otherwise your back boiler could explode (that does happen if such a system is incorrectly installed, I think several people were killed in such an incident in Austria a few years ago), so you need a big water tank that can take the heat. 300 l is small for that, I tried to find figures a while ago and got something like 600 l for the smallest pellet burners.

[@SuperHaptics]

Water also contains a lot of diluted air and when heated expands so that is also i believe sorted by the expansion tank and vent valves. A boiller like a wood burner that can generate very high temperature and might be difficult to control needs the expansion tank. While a system like a heatpump that will keep the water temperature and pressure under tight control, can do without it.

[@sg3260]

Should the wood burner not be open vented separately?

Amazing quality of installation seems a bit of an understatement!

[@klazyy641]

First time I've heard of, much less seen, an air supplied heat condenser. I had a friend who ran an outfitter business up in Canada who installed (by himself, as I gather) an underground heat collector/condenser system and it kept them warm and snug at -59 F during the winter with no need to run a wood stove to augment it. So I know that worked in extreme conditions and am looking forward to see how your system works in a moderate climate. Clear explanations are priceless and you both hit the mark spot on. Thanks---and I'm looking forward to your next episode with whatever you have on the hob.

[@LaReynedEpee]

Air source heat pumps are being used a lot throughout Europe and are even widely-known here in the UK where there is a government not well-disposed to renewable technologies. There's certainly a lot of garbage being pushed about them in our media.

I look forward to seeing update videos on the performance 👍🏻 congratulations

[@MAKEDOGROW]

The only thing we’re a little concerned with is the number of grey days that won’t produce much power. Last winter (which was the worst for this are in a very long time), there were 40 days when we weren’t producing any power and had to use a generator. We’ve beefed up both panels and batteries, but it’s always good to have multiple backups 😀 Plus, who doesn’t love sipping wine by a fire 🤣

We have a large Stone Bastide and adjoining gite for anyone that doubts you can put in old buildings! Insulation is crucial. Its currently 29 degrees outside (I am in the south of france) and the house is a consistent 20 all . year round. We have a wood burner to chug up the direct heat in the winter. You will find that you will have more hot water than you can even imagine. We can have a houseful and gite full and everyone can have showers. we have two dishwashers; two washing machines and we have never run out. We find it runs really well in the winter and we get down to minus 10- 15 in the winter. Panasonic have a model called T cap which functions normally in extreme cold weather.

@MAKDOGROW the heat pumps are being delivered, used in a lot of places now during renovation. They work well as far North as Edmonton, Alberta which can get to -35. The fossil fuel industries have tried to keep people away from both solar, mini turbines and heat pumps. 😡 The number of EV trucks, cars is getting to be far less noticable because there are now so many on the roads, wonderfully quiet.

I'm a mechanical engineer and have been design HVAC and heat pump system for over 15 years you did a better job explaining them than a lot of engineers :) I'm in the states and work for the National Renewable Energy Laboratory (NREL) it's a US government research laboratory. I do a lot of research in energy efficient buildings and on-site energy generation (mostly solar). You an totally power an air source heat pump system on solar, if it's all sized correctly. Just curious if you guys ever made an energy model or heating load model for your house? That it's the best way to predict if a system will be able to heat/cool on the coldest/hottest days. Anyways keep up the great work!

[@AndyCamps]

Great job on the prep work and the heat pump install. I'm looking forward to the video on the ventilation installation. I know the brand of ductwork you're using. 5 tips here. 1. Don't save on the number of ducts. If the duct identifier says AE34, you should not use it for more than 34m³/h per duct. AE48 is 48m³/h and so on. 2. Don't make the ducts too long and avoid unnecessary bends. A rule of thumb is: the outer diameter in cm is the maximum length in meters if you use it for the maximum flow rate (tip 1). 3. Avoid any bends really close to the collectors. If there is residual tension on the duct going into the collector they could leak. 4. Look at the instructions in the box of the collector. These are great. 5. The manufacturer has superb graphs on the combination duct size, length, and pressure drop. Use those to make a detailed pressure drop calculation based on your ductwork layout plan.

[@mr.whitefox9697]

One tip if i may ,attach a pipe or a hose to the pressure release valve to direct the water outside or in to a bucket because the last thing that you want is for something to go wrong and the pressure to rise to the point that the valve opens ( and instead of saving your system )dumping water all over your heat pump potentially creating a short ask me how i know

Yep, once we have the waste pipe installed we’ll run into that. We also need to add a pressure relief valve to the ufh manifold and run a pipe for that too (we weren’t aware we needed that until the guys did the install)

Good luck with the air source heat pump. I have two systems. One for my house and one for my office. They are both air to air and therefore more easily provide both heating and cooling. The issue in winter is that peak heat demand often coincides with minimum solar generation. If the solar system is not excessively oversized then there will be deficits on cold cloudy winter days. This is when the backup system will be required. Insulation and ventilation will determine overall performance. You have put in the effort to understand the system so I am sure it will work great!

[@TheFlyingDutch94]

The expansion tank is for keeping pressure differential stable while the water heats up. This one is just for the expansion of water in the boiler. You really need a bigger seperate expansion tank for the water in the underfloor heating because when the temperature of the water is low and the heat pump starts the pressure drops and the flow rate decrease until it gets the setup temperature. This slows the heat transfer. It is also usefull to use a different tank as a buffer tank from the unit to the underfloor heating so the compressor of the heat pump doesn't open and close many times. An engineer can take a look on this.

Impressive install job by Two Climas. And Kylie did a great job explaining how things worked. Well done guys!

Thank you for the explanation on how heat source pump systems work! I have heard of them but had no clue how they work. We live a few miles from a village that is the first place in the UK to have a ground source pump infrastructure added as a network to a whole street, Im hoping in time it will be rolled out further so we can replace our oil boiler with a ground source heat pump

So exciting to see this progress! We have here in NW Indiana, geothermal heating due to the cold winters. I saw an ad this morning for Water furnace, geothermal which provides heat, hot water and AC. The unit resembles yours, but of course is different. I've had geothermal in a house before. The only problem was we had a toddler who discovered the tubing in the basement (near my sewing room) and decided it was a toy to jump on, causing a leak.

I take my hat off (again!) to both of you … your planning and researching is just mind blowing … thank you Kylie for explaining something so technical on layman’s terms … Huge milestone reached … 👏👏👏Durban SA 🇿🇦

Congratulations! I learn so much with every video you post. Hot / cold water, electricity, and indoor heating must feel like a luxury.

Great video. Very informative. I personally believe these choices will work quite well for you. Look forward to your later outcomes. Blessings.

Glad you chose Daikin as I have had their air con installed in two homes. Never had an issue and it’s quiet and reliable. Well done. Huge move forward.

I think you have an angel watching over you….min 9:38 when you’re explaining about the “misconception of the heat” - a wisp of light floats from above your left shoulder / right corner of window…and it makes sense when talking about “energy”. Just something Interesting. Love your channel!
