The total heat output then becomes 2kw. Storage heaters can then usefully consume "surplus" electricity, or under floor heating is another good heat sink. Dish washers & washing machines should be using pre heated hot water in any case. Intelligent home management computers could be used to manage demand. Switching on a dishwasher would simply mean such a system runs the CHP unit up to full power five minutes before peak demand is required, perhaps electrically heating water for it as it does so. Most energy solutions are going to need multiple sources, PVs will do better in summer when a CHP unit may well spend a lot of time turned off. Intelligent systems can be predictive, sensing outside weather, for example, and maximise on the use of energy systems accordingly.
