Hi,

I don't have one installed but I did go through the process of getting the installers around, pricing etc.  For what it is (heating based on the continuous hot water) it was quite expensive, and it needed some serious ducting internally, and it only heated, not cooled.  And since at the time I had bottled LPG I wasn't sure on the amount of gad it would use (it isn't the best thing in the world to run out of gas whilst in the shower!!

But from memory it did put out quite a lot of heat compared to a heat-pump.

We are also tossing up between a standard gas ducted system (eg Brivis), versus the Rinnai iHeat, versus a standard ducted heat pump system.   We had various quotes and all options range around $10-12K.   It does sound like the Rinnai iHeat system is still quite new on the market?  So good question who has got one and what their experience is?   

The other key consideration is inside and outside noise.  How do these options compare?  Which one is best?   

Pretty sure it has been around for a few years. But I think most people these days use a heatpump system, as it also cools. Gas though is good for heating if you have a cheap mains supply, but expensive on LPG bottles

We ended up going with a Braemar gas central heating system, sales guy said cheaper to run and so far its been great!

Did they provide figures comparing the running costs between the Rinnai and their own brand to back that up? eg the cost per day to heat the house.  Would be interested to know the running costs of these things compared to heat pumps. From what I have heard, gas is one of the  cheapest ways to heat a house out of wood, electricity, although diesel maybe cheaper.
