Combine photovoltaics with air-water heat pump heating + domestic hot water

Hello Elina,

I have already calculated that the heating heat pump can be operated just as cheaply with "household electricity." Therefore, I can save myself the extra hot water heat pump.

Hello Jörg,

I am not a builder; just mod ;)

Do you have a "paper" where you have checked the profitability of the storage?

No, I can't provide that yet, as we have only had the storage in our offer for 3 weeks and therefore have to wait and see what the next year's figures tell us.

Through my sig you can get to my homepage; if you take a look under the tab "Unsere Philosophie" at the left part of the appearing page, you will find the section "Photovoltaik". There I have - to present it seriously with the values from 2012 concerning the costs of electricity sales and purchase (in 2014 you get less for a kWh) - a pdf from our partner available for download. This way you can at least read the estimated values for self-consumption regarding profitability.

Our cooperation partner for photovoltaics is currently installing a complete system at one of our ongoing construction projects. Since I naturally maintain close contact with our builders, I will - the move-in is planned for November 2014 - have the first reliable invoices available only in 2016.

Rhenish greetings

.... is a storage or a control that increases self-consumption! ....

Neither storage nor control increase self-consumption, that would be really stupid ;-)
There are air heat pump manufacturers who make usable photovoltaic inputs immediately and directly available and billable through the control!
