Abstract

The domestic or small scale heating system has a hot water circuit and a second circuit for heating radiators, as in the main patent. The mixing valve is operated by a powered device and the system is controlled by outside temperature sensing thermostats and an adjustable inside thermostat. The valve drive is connected to an adjustable timing device which can cause the value to close quickly or to open in two stages. It is opened half way for a period, then fully opened. The dwell time for the half way position is equal to or more than ten times the time taken for closure.
