With the cost of gas high, i wanted to understand if the combi storage boilers (veissmann, vaillant eco) required the hot water store to be kept hot all the time, or whether if the usage is low it can just use the hot water on demand from the boiler?
I'm asking as id like the option to store water for high demand but typically not need hot water stotage.
Any gurus out there that can help? Thanks
