Re: Cleanaire or Smart-Vent Synergy 

Mavrick, how do you think a product becomes established, some one has to take a punt. (some times they win and sometimes they loose) If we all waited to for every product to be proven in NZ then we would still be living in caves.
I do not understand what are so different about NZ conditions, I keep hearing this.
As far as the Avon Electric (Cleanaire) an excellent company, but their units have been expensive in the past. (this has limited their sales)
Synergy, is based upon a Ventaxia unit out of the UK, so is fairly well established.
As far as HWHP, yes in many cases the importers were the innovators, who used their best efforts to supply cost compative and reliable product. Again at some point someone took the punt.
Why will a plastic heat exchanger rot away, plastic does not seem to rot away in a land fill!!!
By the way I recommend enthalpy heat exchanger, such as lossnay.
Any heat exchange system is better than any PPV system

Re: Cleanaire or Smart-Vent Synergy 

Typical pathetic Kiwis! All the time the same rubbish about the "unique NZ conditions"
One way to keep technically advanced know how and products from overseas away :-((

Re: Cleanaire or Smart-Vent Synergy 

I was on of those who imported air source heat pumps, all that could be done to ensure reliability was done. I purchased 6 unit and tested for 6months. Proir to ordering a couple of containers.
Yhe trail units were fully stripped, wall thinkness of pipes were tested, number and size of cores in cable, solder type, system cleanliness, full fault simulation was undertaken and of course subsequent problems caused. A number of recommendations were made, and seem to have been completed. (at the same time a Swedish engineer was undertaking similar procedures) As an enginner, I am fimilar with imported products, so want to ensure a reasonable level of quality.
Un be known to all costumers(importers in to many countries) the manufacture in its wisdom (or foolishness) decided that it would change it is own production specifications and production methods.
generally as a rule, slightly less material in all components. This is what has caused many of the failures. The first problems did not show for approx a year, after 2 years it became more than just a odd unit. At which at this time I and many others companies withdrew the product of the open market. The cost to the importers (not NZ) was considerable.
Even though there was manufactures faults, most were actually caused by incorrect installation and use. Excurating the manufactures short comings
A heat pump is not a boiler, and can not be tret in the same manor.
No support was given from the manufacture.
Some of the larger companies were able to take this loss, whilst the smaller companies folded. (the position I was forced into, it did not help with finance companies and property developers also folding owing many $1000's)
I still firmly believe that hot water heat pumps are the near future of water heating, very much like air heat pumps went through the ups and downs, now they are extremly main stream, reliable, with sufficent backing.
" You can not build a Rolls Royce for the price of Lada" Some were in between is what we all try to achieve.
Those who purchased the units are the true heros, they have moved in the right direction.

Error in above statement "Not NZ" should read "Not just NZ"

I've also imported a quantity of hot water heat pumps from different manufacturers), with mixed results - the addition problem I had (apart from various failures) was a crooked business partner. The failures have cost me personally tens of thousands of dollars, but I have honoured ALL individual warranties - the only ones I have ignored were units fitted for a large housing company.
A working hot water heat pump is an extremely useful energy saving device - the only problem to resolve is the reliability.

Check out Aquafire HWHP as they are the most efficient and cheapest! They easily deal with lower Sth Island temps.
