No buffer domestic hot water heat pump
We’re thrilled to announce that our heat pumps can be used to generate domestic hot water without a buffer. This innovation makes installation easier, reduces costs, system size, and simplifies controls. Moreover, this method boosts the system’s efficiency.
To guarantee a successful project, here are some suggestions:
- Make sure you choose a larger cylinder for more fluid operations and efficient defrosting.
- If you opt to use Acers, bear in mind you’ll need two of them.
- The low-temperature hot water (LTHW) should be kept within a range of 70-30°C.
Secondary return domestic hot water (DHW) should be reheated with direct electricity, to avoid cyclical temperature control issues.
- The DHW should be produced at temperatures varying from 10-65°C. Note that pasteurisation at this temperature range will take around 6 minutes.
- To ensure proper communication with the Air Source Heat Pumps (ASHPs), the cylinders should be fitted with temperature sensors that can transmit a 10V, 5V, or 0V signal.
- The Plate Heat Exchangers (PHX) and pumps should be sized according to the ASHPs’ summer condition output.
