Abstract: A hydronic space heating system including a buffer tank defining upper and lower chambers in fluid and thermal communication with one another, the upper and lower chambers being separated by a baffle having passages formed therein to allow fluid flow from the lower chamber to the upper chamber to facilitate heat transfer therebetween in a controlled manner, a heat pump associated with the lower chamber of the buffer tank and having an output for heating water in the lower chamber of the buffer tank to a temperature within a predefined temperature range, and an auxiliary heat source associated with the upper chamber of the buffer tank having an output for increasing the temperature of water in the upper chamber of the buffer tank to conditionally supplement the output of the heat pump.

Abstract: A stand for supporting a pressure vessel includes a support body having an upper wall and a sidewall extending downwardly from the upper wall. A locking aperture is defined in the upper wall to permit passage of pressure vessel components therethrough. A plurality of locking latches is disposed along an inner dimension of the locking aperture. The locking latches are configured and adapted to couple with a pressure vessel retaining ring passing through the locking aperture.

Abstract: A stand for supporting a pressure vessel includes a body having an upper wall and a sidewall extending downwardly from the upper wall, an aperture defined in the upper wall configured to permit passage therethrough of a fluid conduit, the fluid conduit being in fluid communication with the pressure vessel, and a locking element provided in connection with the body configured to engage the fluid conduit when in a locked position to inhibit removal of the stand from the pressure vessel.
