When you are spending thousands on a new hot water system, the real question is not what the brochure says. It is what a plumber would actually recommend based on real installations, warranty issues, serviceability, parts, and long-term value.
At RJT Plumbing and Gas Solutions, we look at hot water systems a bit differently to the average homeowner. We are not just looking at the upfront price. We are looking at what is reliable, what is backed properly, what can be repaired sensibly, and what is worth installing in the first place.
That matters because the cheapest system is not always the cheapest system to own.
What actually matters when choosing a hot water system
A good hot water system is not just about efficiency claims or brand recognition. It needs to perform in real Australian conditions, come with decent after-sales support, and make sense if something goes wrong down the track.
That is why we look closely at things like tank material, compressor warranty, whether the heat pump module can be replaced separately, and whether the manufacturer has proper support behind the product.
Some systems look good on paper but do not inspire much confidence once you look beyond the sales pitch.
Solarhart still makes sense in the right home
Solarhart remains a strong option where there is already an existing roof-mounted solar hot water system with panels and tank on the roof. In that situation, replacing like for like can make practical sense, and they are a brand we are comfortable recommending where that type of system is already in place.
Some systems we would not rush to recommend
Not every brand in the market is something we would confidently put forward.
Australia Heat Pump is not a brand we know well enough to recommend.
Thermal Arc, Evo Heat and iStore are also not units we would generally steer people towards. From our perspective, these sit in the cheaper end of the heat pump market and do not offer the level of confidence we would want when recommending a system to a customer.
When it comes to hot water, we would rather point people towards products with stronger backing, better quality, and a clearer long-term service path.
Dux Prodigy 4 is worth considering
The Dux Prodigy 4 is a fairly new unit replacing an older model in the range, and it is one we would consider recommending. It sits in a solid position for homeowners who want a known brand without stepping all the way into the premium end of the market.
Reclaim Energy is a premium option
Reclaim Energy makes good systems. They offer stainless steel tanks with long warranty periods, including up to 15 years on the tank and 10 years on the compressor side. That puts them in the premium category for a reason.
The trade-off is cost. These are expensive systems.
There is also the practical question of after-sales support, simply because the company is based in Victoria. That does not make it a bad product. It just means support and logistics are part of the overall picture when choosing the right unit.
If you want to look at Reclaim in more detail, here is their brochure:

Apricus is better known for solar
Apricus is generally better known for solar products. We know them more in that context than for heat pumps, so it is not a system we would strongly push without more confidence around the product itself.
Rheem is the practical recommendation we keep coming back to
If we had to narrow it down to one brand we are broadly comfortable recommending, it would be Rheem.
That comes down to a few things. Their after-sales support is generally solid, their warranty structure is reasonable, and they have a strong Australian presence. That matters when a customer needs help after installation, not just on the day the system goes in.
We also like that Rheem now has a stainless steel tank with a separate heat pump module. That is a smart design because if the module has an issue later, it can be replaced without automatically replacing the tank as well. From a service point of view, that is a big plus.
For us, Rheem sits in a very sensible position in the market. It is a brand backed by engineering, research and development, and support that makes ownership easier over time.
Panasonic is one of the strongest premium performers
Panasonic is another option we rate highly, especially from an efficiency point of view. Paired with a stainless steel tank, it becomes one of the better premium systems available.
It is also one of the more efficient units on the market and comes with strong warranty support, including up to 15 years on the tank. Once again though, price is the catch. These are not budget systems. They are for homeowners who want higher-end performance and are prepared to pay more for it.
The truth is there is no one-size-fits-all answer
Top-shelf systems like Sanden, Reclaim and Panasonic can be excellent, but they are not cheap. For some households, the premium price is worth it. For others, it makes more sense to choose a system with a better balance of cost, support and serviceability.
That is really the point. The right hot water system depends on your home, your budget, and how long you plan to stay there.
So what would a plumber actually recommend?
If there is an existing roof-mounted solar setup, Solarhart can be a very good replacement option.
If you want a solid mainstream unit, Dux is worth considering.
If you want a premium stainless steel system with strong efficiency, Reclaim and Panasonic are both serious options.
But if you want the practical all-round recommendation based on support, repairability and confidence in the brand, Rheem is the one we would most often lean towards.
Need help choosing the right system?
If your current hot water system is getting older, taking too long to heat, or starting to become unreliable, it is worth looking at your options before it fails completely.
At RJT Plumbing and Gas Solutions, we help homeowners choose systems based on what actually works in the real world, not just what sounds good in the sales material.
