Hot Water in Green Building

Heating Water in Green Homes 

Solar Hot Water

A solar hot water system, installed on a south-facing roof, can be integrated with both domestic water and space heating by way of a highly-insulated, large-capacity hot water storage tank with heat exchanger coils specifically designed for this integration.

A solar hot water system has a short pay-back time period. 

Recirculating Cold Water

In almost every American home there is a waiting period for hot water while the cold water in the pipes runs down the drain. 

To engineer an energy-efficient hot-water system:

1. Optimize the shortest route for hot water to travel.

2. Select the right type of pipe.

3. Choose the right size of pipe.

4. Install a recirculation loop run by an efficient pump which recirculates cooled water in the hot water pipes back to the water heater.

This also adds the convenience of "instant" hot water.

On the Way to the Shower

AndersonSargent ran solar-heated hot water through a towel warming tube on the water's path to the shower in their net zero energy home in Frisco, Texas. A "warm" touch!.
