Re: Heat Pump hot Water v's Solar Hot Water System 13Jun 29, 2016 7:16 pm bpratt One of the issues with heat pump hot water is that the heat pump is part of the tank system, so any failures requires the replacement of everything. Evacuated Tube systems work the best, and we only had to boost once last year, and that was only for the one day when the tank cooled down (we isolated the power from the boost, so we know when the boost was needed). Our system is an Apricus 315l 30 tube with electric boost, and we're in South East Queensland, which makes it easier to go without boosting it. Heat pump systems don't work as well when you are in the cooler climates too. Our heat pumps are located beside the tank. In the same way an air conditioner motor is located on a concrete base outside the house.

In the same way an air conditioner motor is located on a concrete base outside the house. That's a good way to have, the heat pump being separate from the tank... the issue with some is that if the heat pump fails, the entire system has to be replaced.

Check the forum I listed above, https://forums.whirlpool.net.au/forum/143 I've heard Sanden & Siddons are supposed to be good, though I have no first hand experience. Rheem, Dux were supposed to be bad I think, from old threads though.

Purchased from a company in Melbourne. Re: Heat Pump hot Water v's Solar Hot Water System 18May 25, 2020 4:11 pm TraceyWayne Great advice from ddarroch, for what it's worth we went hydrotherm heat pump and 5.2 PV. We're an all electric house running induction cooktop in place of gas. Loving the whole set up, even with 6c feed in tariff last power bill $83, we completely covered our power requirement with solar credit it's the supply charge causing the bill. Roll on battery storage competition then we're going off grid! Heat pump is under house, PVs north facing. Oh hydrotherm is quiet, some heat pumps can be loud. Can't help with solar hot water comparison. Hi Tracey, Planning for a heat pump myself. It's been sometime now, how is the hydrotherm holding up? Re: Heat Pump hot Water v's Solar Hot Water System 19Jul 19, 2020 9:02 pm We had a Sanden for 7 years at previous house, and have moved and are planning to get another one. It draws 1000W for 2-3 hours for 2 people (one of who has long showers) and was at least 90% powered from Solar PV all year as opposed to Solar Thermal which needs expensive boosting. If you are planning to get off gas, then it is a no brainer in my opionion. IT also means that roof space is producing useful energy all day, not just when you need hot water. the sun master is the solar heating to "warm" the water in the tank the S26 is your hot water system which will heat the water (25 degrees?) so with both turned on you… 2 14074 instantaneous is three phase and draws heaps of current, the efficiency comes from not storing it so you don’t lose heat to the environment.
