Which emission systems are the most suitable to combine with a heat pump?

The heat pump (in heating mode) must carry the water to about 30-40°C (86-104ºF) to achieve its best performance. For that reason, it is very important to have emission systems that operate at low temperatures, such as underfloor heating or fan coils. This does not mean that the use of emission systems that require higher temperatures such as traditional radiators cannot be used. It only means that their use will not allow the heat pump to achieve its maximum performance. Even so, this performance will be much higher than what we could achieve with a traditional gas/diesel boiler.
