different principals

They have a high COP (coefficient of performance), they work on relocating heat from he air to the water, and the COP is just the cost of relocating that heat, whereas gas or electricity are a forms of energy that is being transferred to another form of energy (yes, heat is a form of energy)

So gas is about 80% efficient (about 20% goes out through the flue), electricity is about 100% and heat pumps are approximately 300% as they use heat that already exists and simply reloate it

Instantenous gas uses much more energy but only on demand as you are not paying to keep a large tank of hot water at 70 degrees 24/7

again, works off different principals
You say "about" like it's nothing. Wouldn't the efficiency depend on how that electricity was generated?

no, how your power is generated has nothing to do with the efficiency of an appliance

if you generate your own power with an onsite renerable energy plant, then its nothing, but if you are buying your power then its aprox 33 to 37 cents a kw/hr depending on where you buy your power

with those pressures Ryley Smith puts on the kicker, what percentage of them does he bail out when he could have made a charge-down play? To me that's a glaring problem with the game that has an easy rule change solution but the NRL will seemingly never do it.

Is a hot water heat pump like the equivalent of instant gas hot water? Or is it a tank?

Normal HWS -
4-5 parts.
Thermostat, Element can go but cost $40 each and easy to change. If replace the rod in HWS every 8yrs the tank will last 50+

Heat pumps are like having an air conditioner attached to your HWS. IF something goes it will be $$ and parts maybe hard to source. You may save a few bucks on power I guess.

It's funny that we were told gas is better electricity bad but it's about 28% cheaper to use the heat pump. When adding 20degC to 1 litre of water at 12 degC.

That would be right. More wooden spoon winners. A 3 time wooden spoon winner mind you, as we have to give respect where it’s due. Of course Issac Moses comes knocking on the door of a loser club that would be gullible enough to take this unbelievable talent. This is would be a Typical Mon and Jim shit signing.
3 x wooden spoons, 3 x ACL, lets make it 3 x shit clubs and close out Adams trifecta

Please don’t mention that bull dykes name in the forum again Eelo, you just triggered me. Biggest con in politics. Has done f**k all in 20 years.
The worst thing about "that bull dyke" is that she is actually straight and the dyke thing is all an act for her constituents. Political animal.

I'll stick with my instant gas hot water system until someone comes along and replaces it for free.

I only pay 24.3 cent kw/h here in the ACT...but I am getting 32% off the market price.
