Intelligent boilers.

[joni os]

Now we have modulating boilers, out side weather compensation, and apps to turn heating on as we drive home has anyone arranged variable flow temps. to match purpose. ie. >75 C when heating DHW and <65C for underfloor heating. The programme clearly defines the purpose but apart from viessmann 4 pipe setup I'm unaware of any regular boilers with this facility. 1 hour per day in non condensing mode DHW. to ensure boiler is fully condensing, heating, 23 hours seems a reasonable trade off.

Vaillants can be set up for different flow temps for different zones, if you use there weather comp it has to prioritise DHW because of this anyway as the DHW might want a flow temp of 75deg but the heating may want a much lower flow temp depending on outside temp and what the heating curve its set to.

WB system boilers with built in diverter can, Vaillant can, Ideal Vouge can, fairly certain you can with intergas also

the way its going the boilers will be more inteligent than the blokes fitting them

A lot of boilers can, but the manufacturers are not pushing it too much. They don't want the boilers condensing most the time, as amazingly, that will reduce the boilers lifespan!

How does it reduce boiler life?
