I am keeping an eye on the weather in Warwick where Bartimaeus is moored. The temperature there is hovering near to freezing, and definitely below during some recent nights. I’m also watching the temperature inside the boat and the electricity consumption. Just sitting minding its own business, the boat uses around 2KWh of electricity each day. When the temperature drops low enough, the little heater in the saloon comes on. This typically seems to double the power consumption, and has kept the recorded temperature onboard above freezing thus far. I’m very pleased I bought that heater, running the diesel central heating to do the same thing would have been more expensive.
