chiefie:
When we renovated our place, we took out the hot water cylinder and installed an outdoor hot water heat pump. It's great... We gained some space back inside the house, we don't use the main water reservoir in roof and we have hot water most the time.

What brand and model did you install? Have you had any problems with it? Do you run out of hot water sometimes? Nd if you do how long until hot again? Cheers

I like the Bosch unit and it has an electric element for boosting and back up.

Do you know who is offering this for 3.5k? I am looking into getting a HWHP installed in place of the old electric one.

I have got a quote for the Aquarian models -

AQ170 $2800+gst this model is the indoor model and also requires a ducting kit the cost for this is between $100 and $250

AQ275 $3500+gst this is the outdoor model and comes complete

Anyone have one of these in their home? Thoughts?

Where are you located I can possibly find you a local dealer who can do it at that price.

Market penetration for hot water heat pumps in NZ is low so you might not find to many users experience with them. I did know someone who retailed them in aussy who swore by them.

The Bosch or the Aquarian? I am really keen to go for the Aquarian as it is excellent value. But there's very little data on it online.

Personally I like to stick with known brands. With the Bosch you have a large international brand, so you should have access to service support & parts for at least 10 years. My concern with HWHP's is the long term issues that may arise with the electronic controls or refrigeration system. I like the idea that there is an electric element as a backup if there are faults.

When we renovated about 15 years ago,we shifted our hot water cylinder from a cupboard in the living room into the ceiling space. It is practically above the shower, so great showers. I have also installed a wrap to the cylinder.

I'm about to fire into replacing our 1969 HWC with an outdoor HP unit so this is interesting.

I'd been looking at the Bosch unit but the warranty is pretty average. The advantages of it are a low dB rating (~45dB from memory) and a good controller interface. The Bosch Comfort 3000 that's available now is a newer version of the original model, which incidentally, looks an awful lot like the EcoSpring ES300 model. That makes me wonder if the ES and Bosch V1 are made from the same manufacturer. Because of this hunch, i'm leaning further toward the Bosch V2 unit as it's apparently an updated design on their original V1.

The Rheem units provide no error code feedback due to no controller interface, and a friend of mine who's serviced them says they're a nightmare. They demand a massive premium in price, but their warranty is the only thing that stands them apart for me.

I like the aquarian units for their warranty and stainless construction, but they're also noisy at 65dB. They don't run in negative temperatures which can be common around NZ too... There's also absolutely nothing online about them. No installation manuals, no technical data, nada. That doesn't make me feel like they're here to stay.

The warranty issue is the biggest for me. Every heat pump (air to air) manufacturer gives at least a 5 year warranty but you seem to only get 1-2 years on a hot water heat pump. For the investment I would want a decent warranty as if they go wrong it could be expensive.

Yeah, tanks have to be a minimum of 5 years warranty by law in NZ so that's set in stone as a minimum. It's the parts and labour warranty that has me worried the most. I guess it's just a gamble that i'll make enough savings in the first two years to offset the cost enough to be happy to then reinvest in a replacement unit if there's an issue.
