During last winter gas heater servicing I told the plumber to set the unit to 50°C heating water output so I could check if the heaters would get warm enough with a heat pump. 1,5 hours of discussion about old buildings and heat pumps resulted till he complied.
It was just a test setup that could be reverted any time.
