A heatwave continues to grip large parts of Europe, with authorities in many countries issuing health warnings amid searing temperatures.

Southern Spain is the worst-affected region, with temperatures in the mid-40s Celsius recorded in Seville and neighbouring areas.

A new heat record for June of 46C was set on Saturday in the town of El Granado, according to Spain's national weather service, which also said this month is on track to be the hottest June on record.

It depends on the kind of heatpumps, in a lot of cases the heatpump is installed to replace a boiler, reusing the radiators and hot water circulation already available.

Unfortunately in this case the heatpump cannot be used as AC.

Not as AC, but a reversible heat pump can use the heating system for cold water circulation.

It's rather limited, because you run into condensation concerns, but it's still a possibility. A place I used to work at did this. It wasn't perfect, but took some of the edge off.

On the other hand reversible heatpumps work great with floor heating.

Having a cool floor during a heatwave is amazing, plus no noise,

Does that work for ground source heat pumps too? Like could I literally cool my floor with one? For summer and light winter, my air to air unit is fine and air to water is great too, but when it's like -25 or -30 out, the air source units start getting pretty inefficient.

Probably, it should be quite efficient as well.
