We have been located in Latrobe, Pennsylvania since the day we made our first Heat Siphon back in 1983. It is times like these that make me proud of our employees and all their efforts to keep our customers happy and our dealers supplied with the best pool heaters we can make. Compared to a ROOSEVELT DIME Heat Siphon's NEW Water Temperature Sensor BEAD Thermistor is approximately the SIZE OF HIS EAR! Housed in a Titanium Probe tip that is THINNER THAN ROOSEVELT's NOSE. We designed it to have the absolute lowest thermal mass and yet retain the highest thermal conductivity - FAST RESPONSE (typical 1-3 seconds) to changes in pool or spa water temperature.
