Space Heating and Domestic Hot Water :
The space heating is a radiant infloor system and is accomplished by using a high efficiency closed combustion gas fired boiler circulating hot water through the concrete floor.
Domestic hot water is designed to use a tankless on-demand ultra high efficient boiler.
The utility room is configured to have space for solar equipment and a storage tank.
Active solar assisted heating systems are effective and a very worthwhile investment.
Backup heat and wintertime ambience is supplied by a gas or wood fueled freestanding stove adjacent to the thermal mass wall.
In emergency situations the stove can also be used for cooking.
