Unit Heats Both Pool And House

Home heating need not be confined to heating living quarters during the winter; in at least one Christchurch home, the heating unit is in use during the summer months—to heat water for a swimming pool.

Mr R. P. Powell, of Bickerton Street, who recently installed a central heating system in his home, has designed the system so that the water in the swimming pool on his property will be able to be kept between 73 degrees and 75 degrees, instead of between 65 degrees and 69 degrees (the heat of the water without any assistance from additional heating agents) during the summer. Mr Powell said he installed the system himself at a cost of about $l3OO, but that for the system to be installed commerically, it would have cost about $2BOO. It took about six months, in spare time, to install. The house heating is done by water being heated in a fully automatic oil-fired boiler and then passed through pipes to various modern sill-line convection heaters in the house. This is a closed system containing about 150 gallons of water. Water for the swimming pool is heated by being passed

through a calorifier (heating coil) and is warmed by the principle of heat exchange and is then pumped to the deep end of the 11.000-galion swimming pool. The swimming pool water does not come in contact with the house heating water. Mr Powell said both the swimming pool and the house heating sections of the unit could operate simultaneously, or they could operate separately. He said it would take about 70,000 British thermal units to heat the household system and about 100,000 B.T.U.’s to heat the swimming pool water.
