Multi-Temp Hot Water, Radiant, Solar, Pool Heating
and Koi Breeding Pond  Configuration

"Folks, this is a residence that I have been installing and adding to in phases over the last 25 years. The blue boiler is a Buderus (German-made) oil-fired hot water (hydronic) unit that serves the home, which includes several zones of multi-temp radiant heat for all the tile floors, European Panel Radiators for the main and bedrooms, Modine heaters for Heated garage/Classic Car workshop and also supplies the tall, white Buderus Solar tank with plenty of domestic hot water for multiple bathrooms, luxury showers and Jacuzzi tubs. 

The green boiler to the left is a Williamson/Weil McLain that exclusively heats the large, in-ground, Gunite Swimming pool and provides year round warm water for an 8000 gallon decorative Koi breeding pond. The design is mine and the piping is quite complicated given the delicate and highly sensitive Koi. "
