2,Why is knowing the insolation level useful?By knowing the insolation levels of a particular region we can determine the size of solar collector that is required. An area with poor insolation levels will need a larger collector than an area with high insolation levels. Once you know your region's insolation level you can more accurately calculate collector size and energy output.

 

3,What units are used to express Insolation levels?The values are generally expressed in kWh/m2/day. This is the amount of solar energy that strikes a square metre of the earth's surface in a single day. Of course this value is averaged to account for differences in the days' length. There are several units that are used throughout the worldThe conversions based on surface area as follows:1 kWh/m2/day = 317.1 btu/ft2/day = 3.6MJ/m2/day

●  The Solar Loop operates normally with a Differential Differential Controller to heat the Twin Coil Tank through the bottom heat exchange coil.

●  In the Radiant Underfloor Loop the pump activates through the zone valves when either Room Thermostat calls for heat.

●  This loop flows through the top coil in the tank. If the upper tank is below, say, 130ºF boiler controller redirects the flow through the boiler, activating the boiler at the same time. This preserves hot water in the tank for domestic use.

●  The bypass, incorporating a Mixing Valve and check valve, ensures that the floor system cannot overheat by mechanically recirculating it when a set temperature is reached.

●  Normally the set temperature of the immersion heater (just below the top coil in the tank) is set far enough below the boiler set temperature to ensure that the radiant system only takes the solar heat from the tank. In emergencies the immersion heater could be used to supplement the floor heat by raising the immersion heater set point.
