New boiler + smart heating system considerations - OT + Weather Comp

DonnieCorko

I need to get a new boiler and I'm having difficulty deciding which one to go for and also which smart heating system to get installed with it. So I am aware of OpenTerm and also weather compensation.

I'm stuck between using Taddo V3, Taddo X, or Drayton Wiser smart heating system with smart TRVs. I know the Bosch 4000 modulates 1 to 10 so minimum output is around 3 kilowatts or 2.5 kilowatts whereas the ideal logic combi max modulation range I think is 1 to 4 or 1 to 5 with an output of 6 kilowatts, a minimum output of 6 kilowatts.

Now Taddo X doesn't seem to be compatible with Bosch 4000 at least right now in terms of OpenTerm. Taddo X does seem to be compatible with the ideal logic combi max but obviously it has the worst modulation range.

Drayton Wiser seems to support OpenTerm and potentially weather compensation as well. I'm not sure about its compatibility with either of those two boilers. What I'm after essentially is the ability to turn on one rad or two rads in the house without burning through a lot of energy and my understanding of this is that it's better to have a higher modulating lower output boiler but the lack of connectivity with the Bosch 4000 makes me a little bit worried in terms of Taddo.

Any input is appreciated.

Ember eph 16 zone smart controller with smart TRVS is probably the best out there right now. There is no longer a need to break your heating into 3 zones. This gives you 16 individual zones.

Thanks for the reply.

The issue though with the above (I could be wrong) is that it doesnt support openTherm, nor integrate with HA. Plus, it is the same price as Tado X which does all of the above.

Why would you recommend this over Tado/Wiser for example?

Thanks!
