    Vaillant ecotec plus 837 combi

    That's about what I get. The kitchen tap can only be slightly open. Certainly not what I was lead to believe. I'm a little surprised that the water supply is a problem because I can run 2 cold taps simultaneously without significantly affecting the flow. The shower is now noticeably better than...

    Vaillant ecotec plus 837 combi

    As I was advised that the 837 was the right boiler for my requirements, my expectation is that it will produce the flow rate specified. I was quite specific that I wanted to be able to use two bathrooms simultaneously and was assured that this was the boiler for me.

    As far as I can tell the installer left all the settings at their default values. Setting D.36 controls the hot water flow sensor. At the moment the value is 0. Does this setting affect the l/min of hot water the boiler produces or is it the flow rate at which the boiler will start heating the...

    Vaillant ecotec plus 837 combi

    Morris40 - Will the TRV's have been damaged by the reverse flow? I had adjusted the boiler output to 20kW but it did not seem to have any effect on gas consumption, although it did seem that the radiators took longer to get hot. I have now turned the comfort (warmstart) feature off but, as you...

    Vaillant ecotec plus 837 combi

    Hi I have recently had an ecotec plus 837 installed and am becoming a bit concerned by the gas consumption. The boiler was fitted to an existing system of 13 radiators having a nominal heat output of 15.5 kW. Although the boiler output of 28kW far exceeds my requirements, I opted for the boiler...
