Hi everyone,
I have an Ideal Max Heat H18 system boiler with weather compensation installed. My understanding is that while weather compensation controls the heating flow temperature based on the outdoor temperature and the setpoint at the boiler, when there’s a call for hot water, the boiler overrides weather compensation and runs at a fixed 80°C until the cylinder thermostat is satisfied.
I’d like to know if there’s any way to reduce this DHW override temperature, either:
1. Through an installer or advanced settings menu on the boiler.
2. Via the weather compensation controller, if it allows DHW modulation.
3. Using OpenTherm or an alternative controller to gain more control over DHW temperatures.
The system includes a hot water cylinder with a thermostat set to 60°C, but that only dictates when the boiler stops heating – it doesn’t change the fact that the boiler always runs at 80°C for DHW demand.
I’m looking to see if I can lower the DHW override temperature, ideally to match the heating curve more closely or to improve efficiency. Any insights or advice from those familiar with Ideal boilers and weather compensation would be much appreciated!
Thanks in advance.
