Air-to-Air Heat Exchangers for Healthier Energy-Efficient Homes

The heatpump is not able to cool the house - per design. It would need air conditioning.. which would be expensive.

The house is very well insolatated and therefore difficult to keep cool during the warm months. We installed film blocking some of the light on the HUGE windows which are part of the problem.

So we are able to regulate the temperature but the house is warmed up during hot days and not always cooled down enough during the night.

An air conditioner is a just a heat pump.

Why can’t your heat pump run both ways? It’s not that much more expensive!

This is not a supported feature.

Tons of air to water heat pumps can run the cycle in reverse (cool your house) these days. I'd double check if it's a recent installation, it almost certainly does. If so, the question is what your heaters look like. Not every likes cold feet for instance.

Danfoss which is the maker of this (ground heat) pump doesn't support this. This is per design. You can buy an add-on with a separate loop which I find silly.

Thanks for sharing. Do you mean the air-conditioning would be expensive in terms of upfront cost? As I imagine, with the solar, panels, it would be an ideal combination during the summer.

I could install a heat pump which can be run in reverse and cool the house. That would probably be cheap enough to install and use generated energy mostly.

But a heat pump has an internal and external part. The internal part needs to be where it cools and it's ugly too look at.

There are Aircon devices where everything is hidden away but they are expensive.
