    All products I have seen from them is direct from China.

    Daiken are a trusted brand for both major projects and small domestic systems, maybe a bit dearer today but you save that into the future with reliability and a manufacturer who does have after sales support.

    The kitchen or shower room are not always full of warm moist air that we need to get rid of so they will be pulling heat from the kitchen / shower room which has to be replaced, so no savings there.

    If they are pulling the air from outside the house (standard heat pump method) the C.O.P. will drop big time in winter, honestly if you are anywhere in the north of England, Ireland or in Scotland fit a standard immersion at least they are honest.

    Have you seen the Panasonic range of heat pumps? They bought out Sanyos CO2 and also had there own long standing range. They have heat pumps that are high temp 65 flow and ones that guarantee output to -15 degrees. ie 12kW at 7 degrees and 12kW at -15 outside air temp with no back up electric heater, yes the COP drops but overall they have good COP's. They seem very well priced. I just did there training. They are also inverter driven (variable output) with 0.5amp start current.

    I also import and fit wood pellet boilers, take a look at Extraflame's low cost domestic range. MCZ products is also worth looking at. They both do combined stove boilers to from 12kW to 24kW and a range of pellet boilers from 14 to 31kW that are MCS approved and well priced.

    I know the products because I can buy direct from the manufacturers in both Italy and China.

    I am looking at a small heat pump that is mounted outside, easy to fit works with standard cylinders and coils COP of 3.5 when outside temperatures are above 3c drops to 3 when outside temps hit oc.

    Should be interesting to see the engineers final report, it better be a long report considering what it's costing me :-)

    ecocent / Giona / et al take heat from the house, i.e. it will take it from the radiators, underfloor heating etc.
    So in practice you heat the house and then take that heat to heat the water. Some of the units can take air direct from outside.
    It's an air source heat pump by any name. so depending upon how you are planning to heat the house depends upon whether it will be efficient or not.

    From another post:
    The man at Giona strongly advised against using an internal source for the inlet because it would be taking heat out of the house which has to be replaced by drawing heat in from the outside. Logically it makes no sense to me to be pumping warmth out of the house only to draw cold air back in. He stated that the inlet and outlet would both be outside.
    ASHP's based on our experience
    Tier One: Panasonic , Daikin
    Tier Two, Samsung, Mistubishi
    Nibe are unnecessarily complex, Dimplex units cannot comment on, Mistubishi complex to set up CORRECTLY..., Danfoss no direct UK support, so you're on ya own..
    Best Installer Support #1 Panasonic, #2 Samsung.

    Can't pass comment on other manufacturers, all I've fit is Mitsubishi and find them to be really good. Flow rate through heat pump is very important. Avoid microbore, depending on the distance from heat pump to cylinder and size of heat pump but to be safe use 28mm between heat pump and cylinder. I actually find the technical very good (certain lads anyway) pre sales speak to Louis Sousa
