Hello,
I have a fundamental question regarding our new construction. We are planning to install a heat pump and underfloor heating in the ground floor as well as the bathroom upstairs. The bedrooms, however, will be equipped with regular radiators; my wife prefers this because she believes underfloor heating is not particularly healthy. My question is whether the heat pump can still operate efficiently in this case, since regular radiators require a higher supply temperature. Can anyone help me with this?

Sebastian793 Mar 2015 07:35What kind of quote is this? By the way, I find the price suspiciously low – what kind of modules are those? Cheap Chinese imports? Here, I pay almost 10,000 euros (excluding VAT) for LG modules and 6.5 kW, and that is a "good" price. Especially since the company has been around for 15 years, so they have survived all the downturns in the solar industry 😉
The feed-in tariff remains the same from the day of installation and does not decrease. And in summer, you can still generate hot water, which is needed consistently throughout the year. Additionally, you can control various electrical appliances “smartly,” maximizing self-consumption.
Our system will have paid off after 11 years, based on a very conservative calculation, and then it will operate for almost the same length of time again – tax benefits are not even factored in here, so it will actually be faster. On top of that, there will be lower monthly costs, even with a financed photovoltaic system (which you should do for tax reasons).
And connecting radiators to a heat pump is pretty much the most inefficient option – it doesn’t work effectively. Even with low-temperature radiators...
Oh, batteries: in 2-3 years, things will improve a lot – especially regarding price. Right now, even with subsidies, it’s just an expensive toy...
