An elderly relative's hot water system just died after ~30 years service. She pretty much lives by herself in Sydney NSW.
Is say a 250L Dux Water Heater and installed by a Bunnings recommended installer the best option? What is a typical installation cost?
I'm not sure if any of the heat pump deals are worth it and probably too complex for her to manage.
That's what I'm thinking too.
Reclaim has a 10 year minimum warranty. Maybe go with them.
Yes, but 6k+
All hot water tanks have at least 10 year warranty now.
But OP first needs to check if its Off peak.
Being a 250L tank its highly likely.
Hence OP will ned to replace it with another 250L tank.
Rheem has the best name and warranty in the business.
But also the most expensive
Ask your plumber for installation cost
It will be rather heavy and bulky so may be best to get them to supply it as well.
You say all hot water tanks have at least 10 year warranty .. that could be the case with resistive , but certainly not with heat pump.
Also, Rheem is not the best name with heat pumps. Reclaim and Sanden are the bees knees.
@noz: The tanks usually do have at least a 10 year warranty, but a heat pump system comes in two parts (even if combined into one unit). The heat pump part (which is way more likely to have a problem anyway) tends to have a shorter warranty. Reclaim have the best available on the heat pump, with 8 years, followed by Sanden with 7. Others are usually around 5-6 I think.
@noz: Thanks for your comments
But pls review my post
Im talking about replacing like for like.
ie a 250L tank with another 250L tank.
But good to know its different with other hot water systems.
You forgot to mention when it comes to instantaneous gas hot water that Rinnai is acclaimed as the best.
Im not even sure you can replace an off peak 250L hot water tank with a heat pump system reconnected to off peak.
After all we are taking about Off peak (controlled load 1) rates that are half of the Fixed/General rate.
@HeWhoKnows: Fair enough, but the parent and grandparent comments your replied to were both specifically talking about Heat Pump.
As for the Rheem thing, I didn't forget to mention anything. The OP is talking about Electric HWS, not gas.
@HeWhoKnows: Oh do u mean cant renconnect the old off peak to the new heat pump, meaning it would be connected to general usage circuit instead?
Just curious could they just put new wiring to connect new heat pump to control load?
Also curious would that appply to control load 2 aswell?
Is there budget brands heat pumps with similar reliability to rheem but cheaper?
How do heat pumps work btw ? And are they more reliable than a normal water heater?
@ATTS: Resistive is more reliable than heat pump, as it is much simpler. This is why you need to go for a reliable brand when choosing a heat pump HWS. Since resistive is just a heating element, it costs a lot more to run.
I have a resistive HWS, but I have a relay on it that runs only during AGL's 8c/kWh time (midnight to 6am), and also when the sun is shining.
Just curious how offpeak hot water tank affect installation?
Also if off peak means it is on TOU tariff plan?
A decent heat pump is definitely not the cheapest even with STC and rebates. They'll cost more upfront, but you'll recoup it down the line with the higher COP.
Most likely it will break and end up being a headache, especially once the warranty is up.
No more likelihood of breaking than any split system air-con, which is basically never.
Sure if you buy a decent one it will be far more expensive than an old fashion element style system. With a bit of luck it may last half as long, but with only 1 person in the household I doubt the extra costs would ever be recouped.
No more likelihood of breaking than any split system air-con, which is basically never.
There's plenty of reviews out there which say otherwise.
Is say a 250L Dux Water Heater (https://www.bunnings.com.au/dux-250l-3-6kw-proflo-electric-s…) and installed by a Bunnings recommended installer the best option? What is a typical installation cost?
Ring the Bunnings recommended installer and ask for a quote and also get another quote and compare.
Heat pump
Definitely the way to go, see if you can also package it with a PV panel.
Heat pumps can be a problem - had a Quantum unit fail in 5 years, was not happy. These things might save power but the cost over 7-10 years may well not be offset by the power savings ??.
Reclaim Heat Pump are now warranted for 10-15 years depending on the model. Not sure if that offsets it but it might
That's on the tank only. Heat pump unit is 8 years, which is still the best on the market.
Just got to buy a good brand.
Which are the good brands? Most of them have terrible reviews.
Reclaim, Sanden, probably some other ones.
Heat pumps are too boring to write a review, so people usually only write reviews when they have had bad experiences.
Just gone through this process this past week. Reclaim and Sanden are the best, with warranty (and cost) to back it up. The plumber (heat pump hot water specialist) recommended Haier for a cheaper/mid range option.
@ATTS: The guy I spoke to (who seemed to really know his stuff) only mentioned that one, but his website has others listed including Rheem and Aquatech. From other prior research there's also brands like Steibel Eltron, Rinnai and Quantum which are all in that middle range I think but were not on his website. Different installers will have different recommendations and preferences obviously, so grain of salt, but those are some brands that you could compare/research.
Converted gas to Hydrotherm dynamic x8 260L (heat pump) for around $2.1K at the beginning of the year. Also got a quote for emergency replacement for 250L Rheem standard for nearly $2.8K.
Oh nice didnt know u can convert old system to heat pump. Is that common?
Yeah my heat pump only cost me like $99
Subsidies have changed.

Ozb dont like gas lol
Ozb lefties dont like gas lol
FTFY
That’s because your all brainwashed !
Brainwashed in to saving money. Yep, we certainly are.
@Murkymerv: In general heat pump heating is cheaper then gas heating.
You also save a lot of money if you can get rid of all gas and not pay the daily fee. Also if you can get solar you can save even more.
@Aureus: Just curious what is the daily fee? I think i read a while ago it was couple hundred a year just for gas supply to house?
At my old house the HWS died. Bunnings sold the identical same model (DUX). So it was a straight over swap.
Turn off water at mains, turn off power at mains. Disconnect water inlet and outlet tubes, disconnect power,. Remove old HWS and put in place new HWS. Reconnect power, and water inlet & outlet. turn on mains water and power. Is what a plumber would do.
what exactly was the unit that broke down.
Rheem - 442 Series (400L)
Google tells me manufactured 1996-1999.
I would not consider anything but a heatpump. Especially if your state subsidizes them. Also can claim back the solar credits.
Hmm what if someone had a really old solar hot water heater, would heat pump still be recommended in terms of cost savings
250l seems a lot for a single person. Mine is electric 80l. WA based.
I found the noise generated by heat pumps to be a deal breaker.
I think the less you pay for a heat pump, the noisier it is.
How loud is it? What is similar noise to heat pump
Exactly as loud as an air con.
Oh thats not too bad
We had a rheem heat pump and it kept failing since new (2011). Paid so many times for it to be repaired. rheem said as it was installed within 100m of the beach, it will always fail. Fans and other stuff just rusted to nothing. I threatened them with accc, consumer guarantee etc and they did not care. I guess it was in the small print or something. After thousands of $$$ repairs, the local repairer said ‘how about I disable all the heat pump stuff and you use its as a normal hot water heater’. That was 6 years ago and still going strong. Not a large cost either (qld, 4-10 Klein/day summer/wi tee). Off peak.
But I told that Rheem is the best in the business.

Strange saw that comment
Are there other reliable brand similar to rheem price or cheaper?
iStore is a good heat pump brand that isn't as expensive as the top priced ones. I know a couple of people with them, and they have been going problem free for years.
@noz: Thanks
Oh the brand called istore like iphone.
What country was it made in btw? Does that matter aswell?
@ATTS: Heat pump can go in same location, but a bit of extra electrical wiring would need to be done I believe.
I think the cost of heat pump is around 4x cheaper.
I would recommend you joining the MEEH group on FB, you will learn a hell of a lot about heat pumps and other energy efficiencies, and get much better answers than I can give you.
I had Rinnai 160L installed for less than $1400 (new unit+Labour+old unit disposal) +$400 for electrician and timer switch earlier this year.
I bought this house and after about 2 years the heat pump unit stopped working. First time I paid $600 for circuit board change, next time after 3 months the steel tank split and was considered unrepairable. It was outside the warranty period and in any case I didn't have the invoice from previous owner. Decided to go cheap for a simple electric got water. Considered Rheem but was more expensive. Electrician put a new power point and battery backed timer switch, I have solar.
$1410 supply and install Rinnai 250L electric

Hmm so is there reason why normal electric hot water heater so cheap compared to heat pump?
Is it because its outdated and inefficient? Or another reason
Is that a good installer btw, or was it a random google search
I don't know the answer, sorry.
I personally have a continuous Gas because I don't want to have a tank needs to heat up and run out of hot water after someone's had a shower.
I believe they will get a local plumber for your suburb.
I got the Rinnai 26 litre Continuous Flow Hot Water Heater, found someone on HiPages to supply and install, I used this SameHotWaterService website as a price reference guide.
Heat pump almost always involves refrigerant and that causing the extra cost of running extra piping. Resistant hot water is old as the earth tech and very simple to install, hence the price.
I see thanks
Understand mate, its fine!
Oh was urs the instantaneous gas hot water?
Oh i see
I never had hot water run out on me though.
If they contracting too local plumber it should be a decent person right ?since that sameday hot water company seems to operate interstate as well?
Thanks for sharing your story. I cant remember exactly, but pretty sure on those tradie platforms kept having fake reviews and stuff
I also recommend using OneFlare or HiPages and get offers from tradies to do the work, you can read their reviews before choosing the right one
Thanks for rec
The heat pump will be cheaper upfront with the rebates. Most likely it will break and end up being a headache, especially once the warranty is up.
