We can now help you with Toyotomi and Rinnai heating products, both for space heating and domestic hot water.  We are also available for consultations on heating system design for these and other manufacturers and also solar heating.

We have uploaded some information about a project we worked at on the campus of Unity College involving the solar collectors that President Jimmy Carter had installed in the 70's!  Click here for more information.

This is a picture of our Toyotomi OM-148 water heater that does double duty for space heating.
