Tankless water heaters, high efficiency tanked water heaters, solar water heating, high efficiency toilets, low flow fixtures, grey water recycling, rain water recycling


We installed 92 tankless water heaters last year and have installed 64 so far this year. Tankless water heaters reduce the CO and NO2 emmissions form your house by 45%. We encourage all of our customers to change their shower heads out to 1.8 gpm models and change all of their aerators to 1.5 or 1.0 gpm models. All of the toilets we install are HET's. For those customers that want to stay with traditional tank water heaters we have been installing 95% efficient models. We have been sending our technicians to classes taught by the Green Plumbers Association. Recently we have gone through the training to install solar water heating products and are now offering those services.


All of our employees have gone through tankless water heater and solar water heating training. Four of us have been trained on grey water recycling and water audit procedures.

We opened our business two and half years ago. Since we started we have been focused on providing our customers with ways to conserve water and energy. Our goal is to educate our customers on what they can do every day to reduce their energy costs and reduce the emmissions from their home.
