Book excerpt: A study of the use of a low-to-moderate temperature hydrothermal resource for space heating a l4O-home residential community has been undertaken. The approach centers on use of the existing culinary/potable water supply system to supply heated water to the homes, the culinary water being heated at a single pumping station and then distributed throughout the community through uninsulated, buried water mains. The heated potable water is pumped through individual house water-to-air heat exchangers using sealed, magnetic-drive house pumps and returned to the street distribution lines. These house heat exchangers are either add-on, wall mounted, convective heating units or coils added to existing forced air heating systems. The engineering feasibility of this approach has been examined and previously reported. In that work, a real l4O-home subdivision approximately 17 miles from the water treatment/pumping/heating plant was considered, and the results indicate that the thermal losses in the main supply lines to the subdivision and those in the subdivision street mains would be acceptable. That study also considered total water flow requirements, pumping requirements, main heat exchanger sizing, and house system design including house heat exchanger sizing for suitable ranges of design parameters. Throughout the study, a two-thirds design heating load for a typical three-bedroom house under 0°F, 15 mph wind conditions was employed. The engineering feasibility study indicated that such an approach is workable only in communities with significant water usage rates (or flow-through) to maintain a sufficiently high water temperature in the distribution lines and to supply a large percentage of the thermal load required for district or subdivision heating.

Book excerpt: A preliminary study of the feasibility of using existing drinking water supply systems to provide hot water for heating purposes to a typical 140-home subdivision has been undertaken. This preliminary study has centered on (i) types of municipal water system designs and effects of system design upon heating use; (ii) methods of using low-to-moderate temperature water for heating purposes and possible institutional barriers; (iii) identification and description of a typical residential community suitable for hot water heating; (iv) evaluation of thermal losses in the uninsulated main distribution system from the main pumping station having assumed geothermal heating to the subdivision; (v) evaluation of thermal losses in the uninsulated street mains in the subdivision; (vi) estimation of size and cost of the pumping station main heat exchanger to supply geothermal energy to the drinking water; (vii) sizing of individual house heat exchangers; (viii) pumping and power requirements to supply the increased water flow rate through the subdivision street water distribution lines; and (ix) pumping and piping requirements to provide heating water flow from the street lines to a typical residence. From the results obtained thus far, it would appear that the use of existing uninsulated water supply systems will be advantageous in many communities having nearby low-to-moderate temperature geothermal resources.
