Electricity usage

[jabjab]

The live and the minute is the same reading. I just use the daily. Pretty high consumption for one panel.

Can I just go back and quote all my previous posts from this thread?
Fucks sake.

Why are your panties in a knot again?

Your a/c may have a compressor crankcase heater or some other shit for cold weather. Turn the 208v breaker off for the winter. If a hot water tank can burn 45,000 btu/h you’d need 10 kWh+ to match that performance.

I ended up shutting the breaker off for the ac.

Can't justify the 4k extra cost for tankless. Smaller shop coming this week for an estimate and then I'll pull the trigger by next weekend.

Just to give you an idea...a combi tankless I installed in my house, a Rinnai i120CN, was $3600 for the unit. I don't know what NTI goes for, but probably in the similar ballpark...so you would be paying about 8k for them to actually do the work, that's crazy. I am always amused by how much the labor component is.

I am curious if your previous boiler was dual function or not...I was trying to look at your install pics and couldn't tell. Usually your floor heat and your hot water should be two very separate systems, and the water between the two should never mix. I do see a plate heat exchanged, so I wonder if your previous system even fed actual hot water from the tank to the floor, of it it just transferred heat from tank pipes to a whole other dedicated system.

I am no pro on these, but I did build my own hydronic system for my new place, and it has the domestic hot water side to it, and a completely separate closed loop for the floor heat, filled with glycol solution. The two obviously never touch. Kind of curious if your first one was just pumping same hot water through floor as your normal hot water for the house.

Did you say that? I would've.

I actually don't think they do mix. The water in the hydronic system is a closed looped system and doesn't mix with the tank.

Im assuming the labor is so high cause they need to open my ceiling and create a new exhaust vent for a gas furnace. I'm assuming if this was safe it wouldn't have passed inspection but doesn't mean it's the dumbest set up ever created. How the plumber, electricalcan and site manager thought this was an ideal set up is beyond me.

Just wondering if anyone here has looked into the combination furnace/tankless hot water heaters from Gradient Thermal, based in Calgary?

Heard great things, very expensive as it's newer to industry. I wish I knew about it when my place was going up. I have a nice 2 stage has furnace already or I would have done it.

Pretty neat, surprised no-one ever thought about it before. A bit of all eggs in one basket, but at the same time, so is my Combi boiler. I heat my entire 4600 sqf home + 942 sqf garage with that single unit on the wall, and it provides unlimited domestic hot water...so things sure have gotten compact. Even my furnace (which I don't use, just there to circulate air and backup) is pretty small for the house this side. It's smaller than the furnace I had in my old house that was 3x as small.



Now that I think of it.....it has been thought of before...just not in a single package. I know there are setups where instead of a gas fired heat exchanger in the middle of the furnace, they run a radiator that provides heat off of hydronic pipes...and those pipes could be heated by whatever source you want, either a tankless boiler, or a tank heater. Pretty neat stuff out there if you look, but my guess gas furnaces are the most economical, hence why everyone has one.

There is a lot of wasted energy each time heat is transferred. Fire to heat air is the simplest obviously. Fire heating water to heat the air has more losses and the power to run pumps on top of that.

Update:
decided on going to a regular gas furnace as opposed to tankless gas. A tankless gas would require a bigger gas line and I didn't want to mess with that as it would add to the cost and mess.

Regular gas furnace will just need a 3inch vent to outside where we'd run it through a hallway ceiling and then along side a wall in a crested 4 inch bulkhead. Might look a little odd but it's least amount of damage.

Got quoted 7k on the "high side" of things and feel that's a good investment. If it got done at the time of building.. Probably 2/3k difference. We also found out my check valve for the infloor heat was never inspected by the city. Told the builder this and he blamed the city for missing it but I'm pretty sure the plumber should know to request inspection but who knows. Fuck it.

My tankless Navien 200k btu was $4500 installed. It's condensing so my plumber had to bore the foundation for the intake and exhaust

My set up is a bit different. We need to create a three inch vent to the outside and tie it inti the hydronic floor heating

The work has started. Should be fully converted to gas by next week.

[jabjab]

now fully converted to a gas water tank, my Kwh usage has dropped 86% on a daily basis. Love it

Dropped from what to what? Are you with Enmax? Post this chart from your PDF bill.

I haven't gotten a full bill yet. My energy monitoring was saying I was using 90 to 100kw a day. The past two days I've used 10kw/11.

LoL!
I put an oil additive in my car that's saving me 90% on fuel costs, too. Big refineries don't want you to know about this, but there's nothing they can do!

Hope you buy one of these https://a.co/d/hHUQ9H9

Curious to see my nat gas will be, it will definitely going up. Should know in 30 days

[Brent.ff]

I would have immense joy if the cost was the same
