Fuel oil heat pump hybrid installation and control

[@Tustian999]

Great explanation. My oil burner has died. Should I go with an oil or gas dual system? What brand is good? I am in Charlottesville VA and do not have natural gas. Also I only have about 6 feet of height in the cellar. All the articles are about gas systems, is there a reason? Thanks!

[@billcasso5428]

very interesting thanks. What are the dimensions of the outdoor part of this system?

[@legenderekfixes]

Curious to know why the whole furnace was changed instead of just the oil burner.

[@NathansHVAC]

All HVAC equipment has a 15 year design life. 20 years and it is pretty much worn out. A new furnace isn't that much more when the entire system is being replaced.

[@capthwdy08]

Would this be better then doing a oil furnace and add on a heat pump? the oil furnace is 20 years old or so looking to have my oil furnace primary and use the heat pump with the temp are 30 or more and use the oil furnace when it's below 30 degrees i live in Pa

[@blackhelicopters]

I am in the same boat as you, did you go with a heat pump? Upstate NY here

[@marcil7389]

Oh I was hoping to see a real answer here. We replaced a/c coil with HP so we have hybrid system. HP is supposed to work 35 degrees and higher (for heat) and oil for colder temps. But at 40 or 45 the oil furnace is running not the HP. Installers say the settings are right for the 35 degree change. Any ideas what we could do? In Ohio we have a lot of days between 35 and 45 degrees and I don't want to keep burning oil.

Yes I have heat dual use oil when temp drops auto goes to oil... I had a furnace father bought not very old. So we didn't have air so didn't want to get rid of the furnace bc they last 50 or more years. So from what I gather have been told..the 2 system dual is really good idea.. if u already have a furnace bc it helps the heat pump saves it from wear tare .it doesn't run as hard bc u have a another system when temp drop. So saves on it running so much wearing it out. Oil is much warmer .I've noticed when it does get colder it switches to oil. I can cut my thermostats back few degrees ex...like 72 to 69 bc oil is warmer heat it gets to hot when oil comes on set at 72.. think it's a good system. Now my question is...I'm not sure when it switches to oil. Hear anywhere from 35 to 39 whatever they set it at. And another thing is when it gets really cold a heat pump runs on 2 double straps gets hotter when it gets colder. That does 2 things without dual system. It runs runs to keep your hone warm... double straps kick in when it gets really cold and it also run runs and causes your light bill to get higher too bc of the double strip and running more often which is more wear tare on the system..after it gets really cold.. that is why if u have a furnace already dual system is good.i live in a older home built in 1955 no windows has ever been redone or anything... I had the dual system put in already had oil furnace. My light bill in the summer and in the winter has never been over 80 dollars. Highest... usually runs 60 to 70 dollars a month...both summer with air conditioner and winter with heat.. been no new insulation or windows redone in this home at all..have a trane system.. keep thermostat at 71 sometimes 72 oil comes on 69.. house Sq footage is about less than 1000sq feet all one level have a basement but it is not insulates ot anything leaks water so it's not like it helps heat the house or anything. So like my system i was undecided think best thing.. now I have a question I would like to know where and how to check my thermostat to see what temp it is set to switch from heat to oil.. where to find it.. I've heard it is anywhere from 35 to 39.. so my system has heat but not double straps bc it would have to pull higher voltage they say have to have it rewired also so that's another reason I did not go to double strip full heat system already had a fairly new furnace but no air conditioning now have both. Buy like to see what temp it's set on like to push it down to 35 if... it's isn't already for the oil to come on.. does anyone know where to find that temp Guage. Where the temp is set to switch over how I can check it see the setting for that? Thanks hope this information helps someone bc I was completely at a loss didn't know what tonexspect with a dual system. Uses fuel.oil and I have heat pump as well. Just don't kick n to the double strips after it gets colder kicks in oil.. it helps save wear tare on my system doesn't run all the time when it's cold doesn't run light bill.up running all the time n the winter.. hope helps somebody that maybe in limbo as what to do. .now if Iwoukd of not had a furnace already I may have went the other way . But I couldn't see throwing away a fairly new furnace. ...if anyone again can tell me where to look to see what where the temp Guage is set switching from electric to fuel oil. Idk if it was down on the unit or oil furnace . I have a thermostat in the hall for heat air settings. But idk where the setting would be to switch from electric heat to fuel oil what temp it's set at to switch?

[@marcil7389]

@@km376 I thought the temp gauge (for switching) was on the outside unit. We monitored an outdoor thermometer for several days. The system is supposed to switch at 35 degrees but we discovered it is really around 38/39. We decided to leave it be instead of having a service call. Our HVAC company had "checked" the setting so if you know someone in the business they might be able to answer.

Great video. My only concern is why don't you use a combustion analyzer? looking at the flue gas says nothing about O2, CO2 or CO. How do you figure that burner is safe to run? Valves at the pump are great for service and maintenance

[@huesueable]

Great video, I'm in Bowie MD with no access to natural gas. I have an oil furnance. My A/c has died and every contractor has recommended that I do away with the oil furnance and replace with a heat pump. No one has suggested a hybrid with the oil furnance. Do you recommend going with the heat pump? Do you service Bowie area? Thanks

[@biscohface]

What’d you end up doing here? I’m also in the Bowie area with a similar issue

[@reeewhydoihavetochangethese]

Been installing systems for a year and a half, interesting channel man thanks for the content. I'm definitely learning.

[@jonkeefer6865]

how much did this install cost the customer?

[@scottphillips181]

Thank you, I’m interested in the control sequence.

[@xaviergonzalez2127]

Where can I get the schematic for this install. Control?

[@NathansHVAC]

Here is the pdf. www.dropbox.com/s/cr0ieaduo3ur2qw/Propane%20Furnace%20with%20Heat%20Pump%20Hybrid%20Operation.pdf?dl=0

[@DragonZXDragster]

I feel like an idiot for never learning this stuff. But I have a hybrid system. When furnace goes on, one side of house gets heat, other side gets heat pumps colder air. Are both supposed to run at the same time when the furnace kicks on? Also, I'm assuming there's a flap somewhere that's supposed to be pushed by the higher pressure of the Furnace when it runs to prevent that "colder" air from coming in. Exactly what is that thing called so I can look for what it looks like online, find it myself on the duct work and try to see if I can fix it or need to replace it?

[@NathansHVAC]

DragonZXDragster can you make a video of your setup?

[@DragonZXDragster]

I'll see if I can try to, the crawl space under the house isn't the "best" to crawl in lol

[@TheGgin]

Nice Install and explanation, BTW, what brand/model Indoor coil did you use?

[@NathansHVAC]

I used the enhanced efficiency ADP coil. Carrier sells them. Pretty much all the brands are aluminum now.

[@lou198]

Only problem with this setup is when heatpump goes into defrost it blows cold air a better setup is to open white from heatpump defrost board so oil is shut off at 105 keeps cold air from blowing in defrost

[@knighthvac4876]

Great info , thanks for the video !

[@xaviergonzalez2127]

Nice job

[@jimbola77]

very nice thank you for sharing partner!!!!

[@hsulli5800]

awesome job.

[@ultron6931]

It seems a little off that they would be concerned about how much oil they are burning when the water heater is oil, wouldn't they have gone to electric on the water heater too?

[@NathansHVAC]

Yes. The water heater will be changed to electric. Energy costs are the same for fuel oil vs electric. But, the fuel oil water heater is $1500 more. So, electric is a no brainer.

[@ultron6931]

Some Food for thought, when might we see desuper heaters on conventional split air conditioning systems like they have on geothermal heat pumps. Seems more like a luxury item that would be marketed to increase the efficiency of the system. This would help the hot water heating in the summer when the a/c is on.

[@NathansHVAC]

I rarely see those. Natural gas is so cheap. I actually saw a much better product for showers. It is a heat exchanger between the cold water and the drain from the shower. Basically, it is a long 6 foot coax tube that takes the heat from the drain water and passes it to the cold. That way, less hot water is needed for the shower. The cold water is warmed before it hits the fixture. I would imagine it could cut down shower heat usages 50% or more. But, when you have natural gas, the saving is less than $100 per year to use this type of heat exchanger.

[@daveschroers4222]

That's pretty cool. I like that idea.

[@NathansHVAC]

I have 4 systems like this now. No problems with them. No worrying about setting a balance point. It works just like the millions of electric only heat pumps.

[@315hvac]

Nice job! Check out my videos I'm a big oil guy. Whats the make on that highboy? What's the total cost of that changeout. If you want to PM me that's fine. Thanks
