Solar water heating on a home built in 1898.
We just finished a great project on a GREAT classic historical registered house. We installed 2 panels on the 45 degree roof. That roof mount wast some careful work. The water lines to the basement were already installed by the home owner.
The home owner had also installed ~3,000 feet of 1/2″ Pex-Al-Pex tubing under the floors. A radiant barrier was also installed to drive the heat upward for the intended use. The insulation bats were then installed behind the radiant barrier.
We installed a 75 gallon natural gas combi-water heater with a coil in the tank. The radiant floor system is hooked in through the heat exchange loop. The radiant floor tubing is hooked in to a 8 valve manifold that is connected to a controller and thermostats into 3 separate heating zones.
When the thermostat calls for heat it starts the radiant circulation pump and opens the valves for that zone. The system runs until the heat load is satisfied.
The solar loop is tied into the combi tank and provides all the energy the sun has to offer for that day.
We also installed a “Clear Wave” salt-less water conditioning system to keep the system in top shape with no hard water build up.
