    I have a Vaillant Ecotec Plus 837 with normal room stats - i.e. no eBus connected smart controls. I understand, that on it's own accord, the lowest this model will modulate to, is 11Kw - which is too high (I am getting short cycling). Two part question: 1. If I use an eBus connected smart...

    Preparation in case of boiler / smart thermostat failure?

    Before I had my new combi boiler and Tado installed I had an older system with a separate water tank. If that old boiler ever had issues I could simply use the immersion heater in the water tank and still have hot water. Now that my new combi boiler has Tado connected, as far as I can see I...

    I'm about to get a Viessmann 100-W B1KF and plan to have it hooked up to a Tado smart thermostat system. I'm assuming that as the Tado supports OpenTherm, to get that benefit, I should ask the installers to make sure it is in the operation mode highlighted below (from the 4 available)? I've...

    Vaillant Hot Water Mode

    I have just bought a house with a Vaillant ecoTec 637. The previous owner had some terrible Honeywell system installed but took all the controllers.
