Using heat pumps also makes it almost on par with the cost of natural gas.
- nomel 5y agoHeat pumps don't work below -10C, so this really depends on the local climate. You can use geothermal heat pumps, but now you're no longer near par.
- ajuc 5y agoDepends. The ones sold in Poland (and I guess Germany as the climate is similar) are often rated to work from -25C up.
- dispat0r 5y agoHeat pumps are also loud.
- jsilence 5y agoJust as fossil fuel boilers are. That's why you install them in the basement. If you can.
- duckmysick 5y agoThey really aren't. The outdoor units are comparable to air conditioners (60 db). I can't hear mine through the walls.
