Heat Pump Question

    Reading a bit about heat pumps and confused about one thing.

    Can I use the same air to water heat pump to heat underfloor heating and also to supply domestic hot water? Or will I need a second heat pump or an alternative supply for DHW?

    I have a hitachi yutaki-s heat pump in my house and I've been having trouble with the Domestic Hot Water. The temperature of the water is scalding and the showers are either Hot or Cold there's no in-between. I've tried adjusting the temperature setting for the DHW, I tried reducing the cut in/out temperatures and I even tried replacing the mixing valve in the shower to no avail.

    Can someone please help me with this issue?

    Are all your taps like that too?

    Was it a thermostatic mixer or a manual?

    yes they are all manual mixers adjusted by handles. the only thermostats I can find in the house are for the underfloor heating and the radiators. Ive lowered the water temperature to as low as 38 degrees but its still too hot all over the house.
