DHW - what are the benefits?
I previously had a Worcester Bosch (Beginning to think I should have got another one) and hot water was instant on demand, the Vitoden 050-W 30kW I now have has this DHW. My question is when this is off and the hot tap is run, it takes forever to get warm water and even then it quickly goes cold. How can I be guaranteed hot water on demand at any time?
