GEYSERWISE PTC AC/DC Element for 150L/200L Geyser with PV Water Heating System

GEYSERWISE PTC Element, 2.0kW (230V AC), 900W (48-72V DC), can be used in 150L or 200L Geysers with PV Water Heating Systems. Get your water heating system off-grid with no plumbing and no maintenance.

• Save electricity (+/-15%) by replacing your traditional resistive heating element with the Geyserwise PTC Element
• Temperature limiting characteristics ensure safety
• Compact, self-regulating & energy efficient
• Dry burn: can operate in dry air
• For use in 150L/200L Geyser with PV Water Heating System
• Lasts up to ten years

This PTC element can be fitted on the following geysers, with PV Water Heating Systems:

• Tecron & City Heat: you can fit the element as is, no extra component needed
• Duratherm: you can fit the element as is into the flange. You will also need a 22mm T-piece connected to the cold end of the geyser, whereby a stainless steel sensor tube is connected via a brass pocket to the one end of the T-piece
• Franke, GAP: you need a Franke/GAP flange and a stainless steel sensor tube
• Heat Tech, Builders Warehouse: you need a Heat Tech flange and a stainless steel sensor tube
• Kwikot: you need a stainless steel sensor tube and either a 5-Hole Kwikot Flange or a 6-Hole Kwikot Flange (check your geyser)
• Xstream: contact us with your geyser details, so our specialist can define which adapter you need and provide you with a quote

GeyserWise has designed an immersion heater element that offers inherent safety and improved functionality over typical resistance-wire heaters. The heating element makes use of Positive Thermal Coefficient (PTC) chips as the heat source it does not use resistance wire as a source of heat. PTC heating elements are ceramic chips that have self-limiting temperature characteristics. As the PTC chips heat up it reaches a designed temperature at which the heat output decreases substantially and stops it from getting hotter. As ambient temperature increases and less heat is lost, the resistance of the element will increase culminating in a near-zero current draw at its designated temperature.

The dynamic resistance and output of PTC heaters make them an excellent choice for providing controlled electric heating. In many applications, it is possible to do away entirely with thermostatic controls, adding significantly to the reliability of a product. Simplification of design and reduced energy consumption represent significant cost savings for a given application. Safety is an added benefit, since no matter how much current is applied to the PTC; it will never surpass its intended surface temperature.

Geyserwise, based in Cape Town since 2004, designs & distributes electronic thermostats, PV water heating systems, solar water heating pumps & accessories, with the aim to minimise the electrical consumption of the everyday residential electric geyser.
