Just wondering if anyone has an opinion (silly thing to say really...) regarding the various type of hot water systems. Specifically, we need to decide whther to go for one of the storage types (perhaps solar assisted), or an "instant" type, where the water is heated as required.
I'm on a learning mission here....

Hi Perry, I'm really new here but I thought I might chime in since I love our instant hot water system.
We replaced a regular, electric storage system around 6 years ago and have never looked back.... I love being able to program the bathroom temperature and the kitchen temperature at different levels - its also nice to just turn on the tap and have the exact temperature I want.....
Our electric bill also went down considerably when we switched over (we also switched over to a gas oven at the same time so the savings would have been for both of them) and our gas bill whilst it increased is still cheaper than the electricty one was before the switch....

I'd go the instant - but check the prices cause its an area that PD are pricey with the upgrade cost! I cant remember exact costs but they offered us two larger sizes in the normal storage type system and then an instant system - they didnt offer anything with solar hot water.
I think the cost they offered to upgrade to instant was about the same as they actually cost to buy one outright! I wouldnt think they would be that much harder to install! Im not sure if its something that can be organised yourself after PD are done.

We have purchased 400L solar hot water system for 4500 all together. We had the same system in the old house and we have never used electricity during 3 years we lived with it.
In QLD as far as I know you can only have gas system or heat pump in new house from last year. Our builder offered us a heat pump but we wanted to be green... for the environment
In January we have received a certificate for sustanaible house together with $500. We spent a lot of money for energy and water saving devices and this was good decision. Dont go for gas if you don't have a supply of a gas in your area otherwise you will start paying to much.

After a quick search, I found what might be the perfect solution....
This little ripper is a gas instant hot water system, without a pilot light, which senses the temperature of the water coming in (say, from a solar panel mounted on the roof with a tank), and boosts the temerature with gas if required.
I've emailed the resellers here in Victoria for further information.
Of course, the biggest problem here is not regarding the host water system - I've learned that the builder (PD) is reluctant to include "non-standard items", and charges far more than is really justified.
I'll update this thread (and our blog) with more info as I receive it.

yeah, good luck with PD - had our stuff out last night - the upgrades they offered us were a bigger storage (aquamax) and a Rinnai Infinity! So will be interested to see if they will do one of those for you!

Never ceases to amaze me at how these companies will say they want to be energy efficient etc, but will prevent you from installing more efficient devices.
I'll let you all know what I find - the inifinty has a nice option which is a water saving pre-heat option, but no solar assist.

Here's something which Porter Davis may go along with - it's the Rinnai Infinity with solar boost, and has the tank on the ground so the roof doesn't need any additional strenghening.

nice! Anyone happen to have one of these babies?

I haven't been quoted as yet - we have our tender appointment tomorrow (Monday) so I'll be asking them.
One of the problems associated with going with a large company is that they can be very inflexible - so they may not even want to come to the party with this.
More info tomorrow!

Ok, here's the results of our meeting yesterday with PD. The site costs are discussed in other threads, or you read about them on the blog (probably tomorrow, when I get a chance to update it!).
The hot water service offered as standard is a storage system (Rheem) 135 litre. That's included in the house price.
I asked about the upgrade to solar. In particular I was interested in the Rheem gas boosted solar system, which has the tank on the ground instead of the roof. "Yep - no problem" says the consultant....
Me: "Yikes! Is it f*n gold plated?"
You get the general drift. There is another option that PD offer - the solar gas boosted system meets the 5 star energy requirements, without the need for a water tank for flushing dunnies - so if you delete the water tank and include the solar system, it's a $1600 upgrade.
In the end, given that our site costs have blown out by $9k, we decided to go with the Rheem Infinity 26, with two temperature controllers, and keep the water tank (which we think is important).
The cost to us of upgrading the 135 litre job to the Infinity 26 is still around the $1600 mark.
There's no doubt that the prices that these builders charge for such upgrades is high, however everyone makes their own decision in the end!
Thanks to everyone for their input - as you can see, we listened to your recommendations.
